How much money will Karia have in this account if she keeps it for 5 years?The formula accrued amount in a compounded interest is expressed as;
A = P( 1 + r/n )^( n × t )
Where A is accrued amount, P is principal, r is interest rate and t is time.
Given that:
Principal P = $10,000Compounded annually n = 1Time t = 5 yearsInterest rate r = 2.2%Accrued amount A = ?First, convert R as a percent to r as a decimal
r = R/100
r = 2.2/100
r = 0.022
Plug the given values into the above formula and solve for A.
A = P( 1 + r/n )^( n × t )
A = 10,000( 1 + 0.022/1 )^( 1 × 5 )
A = 10,000( 1 + 0.022 )^( 5 )
A = 10,000( 1.022 )^( 5 )
A = $11,149
Therefore, the accrued amount after 5 years is $11,149.

Write an equation that helps D'angela determine the amount of money she must save each month to 500$ in her saving account
The equation that helps her is $65 + 5m = $500. D'angela must save $87 each month for the next 5 months to reach her goal of having $500 in her savings account.
What is system of equation?A group of equations that must be solved simultaneously is referred to as a system of equations. The variables in the equations are interconnected, and the set of values for the variables that satisfy all of the system's equations is the solution. Depending on whether the equations feature linear or nonlinear interactions between the variables, a system of equations can be either linear or nonlinear. A vast range of phenomena, including physical systems, economic systems, and social systems, are modelled using systems of equations, which appear in many branches of mathematics and science.
Let us suppose the amount of money saved by her = m.
The, for 5 months the amount saved is = 5m.
Given an initial deposit of $65, we have the equation of total amount as:
T = $65 + 5m
Now, she needs to save $500 thus,
$65 + 5m = $500
5m = $500 - $65
5m = $435
m = $87
Hence, D'angela must save $87 each month for the next 5 months to reach her goal of having $500 in her savings account.

Find h (-1).
The indicated value h(-1) has a value of 0 when evaluated
Find the indicated value of the functionFrom the question, we have the following parameters that can be used in our computation:
f(x) = - 2x ^ 2
g(x) = x - 3
h(x) = 2f(x) - g(x)
The indicated value of the function is

Suppose that the value of a stock varies each day from $9.82 to $26.17 with a uniform distribution. Find the third quartile; 75% of all days the stock is below what value? (Enter your answer to the nearest cent.)
The third quartile if the distribution is $22.08.
How to find the third quartileTo find the third quartile, we need to find the value of the stock that separates the top 25% of days from the bottom 75%.
Since the distribution is uniform, we can find the third quartile by taking 75% of the range and adding it to the minimum value.
The range of the stock is:
$26.17 - $9.82 = $16.35
75% of the range is:
0.75 x $16.35 = $12.26
Adding this to the minimum value gives us the third quartile:
$9.82 + $12.26 = $22.08

The lengths of the sides of a right triangle are three consecutive integers, right, and solve an equation to find the three integers
The only possible solution is x = 2. Therefore, the three consecutive integers that form the sides of the right triangle are 2, 3, and 4.
How to find side of triangle?Since they are consecutive integers, let's assume that the hypotenuse, which is the longest side of the right triangle, is x+2, as it is three units longer than the shortest side.
In a right triangle, the hypotenuse's square is equal to the sum of the squares of the other two sides, according to the Pythagorean theorem. We can thus write:
[tex](x+2)^2 = x^2 + (x+1)^2[/tex]
Expanding the squares, we get:
[tex]x^2 + 4x + 4 = x^2 + x^2 + 2x + 1[/tex]
Simplifying and rearranging terms, we get:
[tex]2x^2 - 2x - 3 = 0[/tex]
We can solve this quadratic equation by using the quadratic formula:
x = (-b ± [tex]\sqrt{b^2 - 4ac}[/tex]) / 2a
where a = 2, b = -2, and c = -3.
Plugging in these values, we get:
x = (-(-2) ± [tex]\sqrt{((-2)^2 - 4(2)(-3)))[/tex] / 2(2)
x = (2 ± [tex]\sqrt{(4 + 24))[/tex] / 4
x = (2 ± [tex]\sqrt28}[/tex] / 4
x = (2 ± [tex]2\sqrt{7}[/tex]) / 4
x = 1/2 ± [tex]\sqrt{7}[/tex]/2
The only option is x = 2, since x must be an integer. As a result, the numbers 2, 3, and 4 are the three consecutive integers that make up the sides of the right triangle.

The cost to rent a car from Rent a Wreck is $15 a day plus a $30 deposit. The cost to rent a car from Barely Running is $20 a day. How many days would you have to rent the car for the cost of both companies to be the same?
In the equation , cost of both companies will be same to rent a car is 6 days.
What is equation?
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
Here the deposit for the rent car in Wreck = $30
Cost for renting in Wreck = $15 per day
Cost for renting in Barely = $20 per day.
Here let us take the number of days as x.
Then, Cost for renting in Wreck = 15x+30
Cost for renting in Barely = 20x
To rent a car , if cost of both companies is same then the equation is,
=> 15x+30 = 20x
=> 20x-15x = 30
=> 5x = 30
=> x = 30/5 = 6
Hence We have to rent a car for 6 days the cost of both companies to be the same.

Answer:
|x| > 6
Step-by-step explanation:
The correct statement is: |x| > 6.
This means that the distance between x and 0 on the number line is greater than 6 units, so x can be any number greater than 6 or less than -6.
The options given are:
|x| < 6: This statement indicates that the distance of x from 0 on the number line is less than 6 units. In other words, x could be any value between -6 and 6, not including -6 and 6.|x| > 6: This statement indicates that the distance of x from 0 on the number line is greater than 6 units. Therefore, x could be any value less than -6 or greater than 6.|x| = 6: This statement indicates that the distance of x from 0 on the number line is exactly 6 units. Therefore, x could be either 6 or -6.|x| ≥ 6: This statement indicates that the distance of x from 0 on the number line is greater than or equal to 6 units. Therefore, x could be any value less than or equal to -6 or greater than or equal to 6.|x| ≤ 6: This statement indicates that the distance of x from 0 on the number line is less than or equal to 6 units. In other words, x could be any value between -6 and 6, including -6 and 6.Therefore, the correct statement is |x| > 6.
here's how to express the statement |x| > 6 as an inequality part 10a^2
| x | > 6
Squaring both sides of this inequality, we get:x^2 > 6^2
Simplifying, we get:x^2 > 36
Multiplying both sides by 10, we get:10x^2 > 360
So the inequality we get after multiplying both sides by 10 is:10x^2 - 360 > 0
Therefore, the inequality for |x| > 6 in terms of 10a^2 is:10x^2 - 360 > 0
Note that this inequality does not directly involve "a," as it is not mentioned in the original statement.

B. 2.75x+1.95y = 750, where x is # of chicken sandwiches and y is # of hamburgers
C. 2.75x+1.95y ≥ 750, where x is # of chicken sandwiches and y is # of hamburgers
The correct option is A, the inequality is:
2.75x + 1.95y ≤ 750
Which inequality models the situation?Let's define the variables we will be using:
x = number of chicken sandwiches
y = number of hamburgers.
We know that the budget is $750, and the chicken sandwich costs $2.75 to make and the hamburger costs $1.95 to make, then we can write the inequality:
"Total cost equal to or smaller than 750"
2.75x + 1.95y ≤ 750

y = 2x² + 8x + 6
у
(0.5, [?]). ([ ], [ ]
Answer:
(½,0),(1,0)
...............
Answer:
Step-by-step explanation:
To find the x-intercepts of a function, we set y = 0 and solve for x.
For the function 2x² - 3x + 1:
2x² - 3x + 1 = 0
We can use the quadratic formula to solve for x:
x = [ -(-3) ± sqrt( (-3)² - 4(2)(1) ) ] / (2*2)
x = [ 3 ± sqrt(1) ] / 4
x = 1/2 or x = 1
Therefore, the x-intercepts are (1/2, 0) and (1, 0).
For the function y = 2x² + 8x + 6:
2x² + 8x + 6 = 0
We can simplify this equation by dividing both sides by 2:
x² + 4x + 3 = 0
This equation factors as:
(x + 3)(x + 1) = 0
So the solutions are x = -3 and x = -1.
Therefore, the x-intercepts are (-3, 0) and (-1, 0).
For the coordinates (0.5, [?]).
To find the y-coordinate of the point (0.5, [?]), we can substitute x = 0.5 into the equation for the function:
y = 2(0.5)² + 8(0.5) + 6
y = 2(0.25) + 4 + 6
y = 5.5
Therefore, the coordinates are (0.5, 5.5).
For the coordinates ([ ], [ ]).
Without knowing the specific function, we cannot determine the x-intercepts or any other information about the graph. We would need to know the equation of the function or have additional information about the graph.

What is triangle?
A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry. A triangle is defined by its three sides and the three angles formed by those sides.
To find the lengths of PQ and QR in triangle RPQ, we can use the law of sines:
sin(R) / RP = sin(P) / PQ = sin(Q) / QR
We are given R = 30° and P = 60°, so we can find Q:
Q = 180° - R - P
Q = 180° - 30° - 60°
Q = 90°
Now we can use the law of sines:
sin(30°) / 4 = sin(60°) / PQ = sin(90°) / QR
Simplifying this equation, we get:
PQ = (4 * sin(60°)) / sin(30°) ≈ 6.93
QR = (4 * sin(90°)) / sin(30°) = 4 * 2 ≈ 8
Therefore, PQ ≈ 6.93 and QR ≈ 8.

Considering this data, how many of the next 20 pastries served should you expect to be bran muffins?
we should expect 4 of the next 20 pastries served to be bran muffins.
How to solve the question?
To calculate the expected number of bran muffins out of the next 20 pastries served, we need to first determine the proportion of pastries that are bran muffins out of the total number of pastries observed.
The total number of pastries observed is 10 (1 poppy seed muffin + 3 cinnamon rolls + 2 bran muffins + 2 apple fritters + 2 croissants). Out of these, 2 are bran muffins. Therefore, the proportion of pastries that are bran muffins is 2/10 or 0.2.
To calculate the expected number of bran muffins out of the next 20 pastries served, we simply multiply the proportion of bran muffins by 20.
Expected number of bran muffins = 0.2 x 20 = 4
Therefore, we should expect 4 of the next 20 pastries served to be bran muffins.
It's important to note that this calculation assumes that the proportion of bran muffins served remains the same for the next 20 pastries. If there are any changes in the pastry selection or the proportion of each pastry, the expected number of bran muffins would also change.

(a) P (X < 15)
(b) P (X > 30)
(c) P (18 ≤ X ≤ 25)
2. Assume ∼(0,1). Find the following:
(a) a such that P (X < a) = 0.95
(b) b such that P (X ≤ b) = 0.05
(c) c such that P (X > c) = 0.8485
1) The value of given random variable having mean 20 and variance 25 is (a) 0.1587, (b) 0.0228 and (c) 0.5328.
2) The z-score corresponding to a probability of a) 0.95 is 1.645, b) 0.05 is -1.645 and c) 0.1515 is -1.04.
What about mean?The mean is a measure of central tendency, which represents the average value of a set of numbers. It is calculated by adding up all the values in the set and then dividing by the total number of values.
According to question:1) (a) We can standardize the random variable X using the formula z = (X - μ) / σ, where μ is the mean and σ is the standard deviation. Therefore,
z = (15 - 20) / 5 = -1
Using a standard normal distribution table or calculator, we can find P(Z < -1) = 0.1587.
(b) Similarly, we have
z = (30 - 20) / 5 = 2
Using the standard normal distribution table or calculator, we can find P(Z > 2) = 0.0228.
(c) To find P(18 ≤ X ≤ 25), we can again standardize the random variable:
z1 = (18 - 20) / 5 = -0.4
z2 = (25 - 20) / 5 = 1
Then we can use the standard normal distribution table or calculator to find P(-0.4 ≤ Z ≤ 1) = 0.5328.
2) (a) Since we are given that X is a standard normal random variable, we can use the standard normal distribution table or calculator to find the value of a such that P(X < a) = 0.95. From the table, we find that the z-score corresponding to a probability of 0.95 is 1.645. Therefore,
a = μ + σ * z = 0 + 1 * 1.645 = 1.645
(b) Similarly, we can find the value of b such that P(X ≤ b) = 0.05 using the standard normal distribution table or calculator. From the table, we find that the z-score corresponding to a probability of 0.05 is -1.645. Therefore,
b = μ + σ * z = 0 + 1 * (-1.645) = -1.645
(c) We want to find the value of c such that P(X > c) = 0.8485. Since the normal distribution is symmetric about the mean, we know that P(X > c) = 1 - P(X < c), so we can find the value of c such that P(X < c) = 1 - 0.8485 = 0.1515. From the standard normal distribution table, we find that the z-score corresponding to a probability of 0.1515 is -1.04. Therefore,
c = μ + σ * z = 0 + 1 * (-1.04) = -1.04.

The area of each triangle to the nearest square inch is approximately 95 square inches.
What is triangle?A triangle is a 2-dimensional geometric shape that consists of three straight sides and three angles. It is one of the basic shapes in geometry, and it is widely used in various fields such as mathematics, engineering, architecture, and art.
According to given information:To find the area of an equilateral triangle with a radius of 12.7 inches, we can use the formula:
Area = [tex](\sqrt{(3)/4})[/tex] x [tex](side)^2[/tex]
where side is the length of one of the sides of the equilateral triangle.
We know that the radius of the equilateral triangle is 12.7 inches, which means that the distance from the center of the triangle to one of the corners (i.e., the length of one of the sides) is also 12.7 inches. To find the length of the side, we can use the formula for the height of an equilateral triangle:
and solve for side:
side = Height / ([tex]\sqrt{(3)/2[/tex]) = (2 x Height) / [tex]\sqrt{(3)[/tex]
Plugging in the value of the radius, we have:
side = (2 x 12.7 inches) / [tex]\sqrt{(3)[/tex] ≈ 14.67 inches
Now we can use the formula for the area of an equilateral triangle:
Area = ([tex]\sqrt{(3)/4}[/tex]) x [tex](side)^2[/tex]
Plugging in the value of the side, we have:
Area = ([tex]\sqrt{(3)/4[/tex]) x [tex](14.67 inches)^2[/tex] ≈ 94.71 square inches
Therefore, the area of each triangle to the nearest square inch is approximately 95 square inches.

What is the period and amplitude of a wave?The period and amplitude are two important characteristics of a wave.
Period: The period of a wave is the time it takes for one complete cycle of the wave to occur. The period of a wave determines its frequency, which is defined as the reciprocal of the period.
Amplitude: The amplitude of a wave is the maximum displacement of the wave from its equilibrium position. In simpler terms, it represents the height or strength of the wave.
In then given graph, the period of the wave = 1 complete cycle in 4 months = 4 months/cycle = 4 months
Amplitude = 84 degrees Celsius.

Billy has x pounds. Liam has twice as much money as billy. Nicola has 3 times as much money as liam. The total amount of money they have is £180 pounds.
A) form an expression in terms of x and find out how much money they have.
Answer:
Billy has £20, Liam has £40, and Nicola has £120. The total amount of money they have is £180, as given in the problem.
Step-by-step explanation:
Let's start by defining the variables:
Billy's money: x pounds
Liam's money: 2x pounds (twice as much as Billy)
Nicola's money: 3(2x) = 6x pounds (three times as much as Liam)
The total amount of money they have is £180, so we can write an equation:
x + 2x + 6x = 180
Simplifying the left side of the equation:
9x = 180
Solving for x:
x = 20
Now we can find out how much money each person has:
Billy: x = 20 pounds
Liam: 2x = 2(20) = 40 pounds
Nicola: 6x = 6(20) = 120 pounds
