Probability:
Probability refers to possibility. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.

Step-by-step explanation:
Brad wants to have $14832 available as a down payment for a house in 3 years. How much must he deposit now at
9.3% compounded monthly to reach that goal?
Round final answer to the nearest cent (2 decimal places)
Answer:
P = $11233.08
Step-by-step explanation:
Another word for deposit is the principal and the compounded monthly indicates we're working with compound interest.
The formula for compound interest is:
[tex]A(t)=P(1+\frac{r}{n} )^{rt}[/tex], where P is the principal ("deposit"), r is the rate, n is the number of compounding periods, and t is the time.
Before solving, we will need to convert the percentage to a decimal (9.3% to 0.093) and remember that n = 12, since there are 12 months in a year.
Thus, we will need to solve for P to find Brad's deposit:
[tex]14832=P(\frac{0.093}{12})(^{12*3})\\14832=P(1.00775)^{36} \\14832=1.32038641P\\11233.07532=11233.08=P[/tex]

What are inequality equations in algebra ?
When you first begin learning algebra, the equals sign is used to denote that two items are, in fact, equal to one another. As an illustration, consider the equations 3 = 3, 5 = 3 + 2, apple = apple, pear = pear, etc. When compared, an inequality reveals two things: first, that the objects being compared are not equal, or at the very least, they are not always equal; and second, how they are uneven.
Consider the provided inequality.
5x + 1/3(3x+6) > 14
Distributive property:
a (b +c)= ab + ac
By the distributive property.
5x + 1/3 * 3x + 1/3 * 6 > 14
5x + x + 2 > 14
Add the like terms
6x + 2 > 14
Subtract 2 from both sides.
6x > 12
Divide both sides by 6.
6x/6 > 12/6
x > 2
Hence, value of x for the given inequality equation will be greater than 2 i.e, x > 2.

The equation for the red graph is y = f(x/2).
We are given a graph. The graph shows two functions. A function connects an input to an output. It is similar to a machine with input and output. And the result is somehow connected to the input in some way. One of the functions is depicted by black lines. We need to find the equation of the function represented by the red lines.
We can see that the function represented by the red lines can be formed if the black lines are stretched horizontally. The black lines can be stretched horizontally by a factor of 2 to form the red lines. A function y = f(x) can be stretched horizontally by a factor of "k" as given below.
y = f(x/k)

Part 1
Arrivals to a bank automated teller machine (ATM) are distributed according to a Poisson distribution with a mean equal to per minutes. Complete parts a and b below.
The probabilities, using the Poisson distribution, are given as follows:
a) Three customers in five minutes: 0.1805 = 18.05%.
b) Fewer than two customers in ten minutes: 0.0916 = 9.16%.
What is the Poisson distribution?The probability mass function of the Poisson distribution is presented as follows:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
The parameters of the Poisson distribution are:
x is the number of successes that we want to find the probability of.e = 2.71828 is the Euler number[tex]\mu[/tex] is the mean in the given interval or range of values of the input parameter.The mean is of two arrivals per five minutes, hence:
[tex]\mu = 2[/tex]
The probability of exactly three arrivals in five minutes is:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 3) = \frac{e^{-2}2^{3}}{(3)!} = 0.1805[/tex]
For ten minutes, the mean is given as follows:
[tex]\mu = 2 \times 2 = 4[/tex]
The probability of fewer than two arrivals is:
P(X < 2) = P(X = 0) + P(X = 1).
In which:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-4}4^{0}}{(0)!} = 0.0183[/tex]
[tex]P(X = 1) = \frac{e^{-4}4^{1}}{(1)!} = 0.0733[/tex]
Then:
P(X < 2) = P(X = 0) + P(X = 1) = 0.0183 + 0.0733 = 0.0916 = 9.16%.

Step-by-step explanation:
The answer for no 7 can be calculation as follows
Since both rectangles are similar, then the corresponding side are proportional, and it follows
[tex]\frac{\overline{KJ}}{\overline{AB}}=\frac{x}{\overline{AD}}[/tex]
[tex]\frac{48}{144}=\frac{x}{72}[/tex]
Where [tex]x[/tex] is the line segment [tex]\overline{MJ}[/tex]
Multiply both sides by [tex]72[/tex] to isolate [tex]x[/tex]
[tex]\frac{48}{144}\times 72=\frac{x}{72}\times 72[/tex]
[tex]\frac{48\times 72}{144}=x[/tex]
[tex]\frac{3456}{144}=x[/tex]
[tex]24=x[/tex]
Since the value of [tex]x[/tex] is [tex]24[/tex], then the length of [tex]\overline{MJ}[/tex] is [tex]24[/tex] in
The answer for no 8 can be calculation as follows
Since both rectangular frames are similar, then the corresponding side are proportional, and it follows
[tex]\frac{w_2}{w_1}=\frac{x}{h_1}[/tex]
Where [tex]w_2[/tex] is the width of frame [tex]2[/tex], [tex]w_1[/tex] is the width of frame [tex]1[/tex], [tex]x[/tex] is the height of frame [tex]2[/tex], [tex]h_1[/tex] is the height of frame 1
Substitute [tex]8[/tex] for [tex]w_2[/tex], [tex]12[/tex] for [tex]w_1[/tex], [tex]15[/tex] for [tex]h_1[/tex]
[tex]\frac{8}{12}=\frac{x}{15}[/tex]
Multiply both sides by [tex]15[/tex] to isolate [tex]x[/tex]
[tex]\frac{8}{12}\times 15=\frac{x}{15}\times 15[/tex]
[tex]\frac{8\times 15}{12}=x[/tex]
[tex]\frac{120}{12}=x[/tex]

1. The relationship as a function r = f(t) is: r = (9 - 2t)/9.
2. The numeric value at t = -9 is: f(-9) = 3.
3. The value of t for which f(t) = 5 is t = -18.
What are the desired measures?The relationship is given as follows:
9r + 2t = 9.
To write the relationship as a function of t, we have to isolate the variable r as a function of the variable t, hence:
9r = 9 - 2t
r = (9 - 2t)/9.
To find the numeric value at t = -9, we replace the lone instance of t in the relationship by -9, hence:
r = (9 - 2(-9))/9 = 27/9 = 3.
To find when f(t) = 5, we have to find t for which f(t) = 5, hence:
9r = 9 - 2t
2t = 9 - 9r
2t = 9 - 9(5)
2t = -36
t = -36/2
t = -18.

The solution for the linear equation:
x - (2/3)*x - (1/2) = (1/3) + (5/6)*x
Is x = -5/3
How to solve the linear equation?Is hard to understand what you wanted to write, but I assume that the linear equation that we need to solve is:
x - (2/3)*x - (1/2) = (1/3) + (5/6)*x
To solve this linear equation, we need to isolate the variable x in one of the sides of the equation
To do so, we move all the terms with "x" to the left side and the terms without to the right side:
x - (2/3)*x - (5/6)*x = 1/3 + 1/2
Now we solve this:
x - (4/6)x - (5/6)x = 2/6 + 3/6
x - (9/6)*x = 5/6
We can write the "1" in the first term as 6/6
(6/6)*x - (9/6)*x = 5/6
(-3/6)*x = 5/6
-3x = 5
x = 5/-3
x = -5/3

The outlier of the data is 14.16 gram
What is Outlier?An outlier is a data point in statistics that dramatically deviates from other observations. An outlier may reflect measurement variability or it may point to an experimental error; the latter is occasionally removed from the data set. In statistical analyses, an outlier can result in significant issues.
Given:
Weights of the samples are 13 g, 14 g, 23 g, 11 g, 15 g, 14 g, 14 g, 12 g, 13 g, 15 g, 14 g, and 12 g.
So, the outlier is
= 13 x 2 + 14 x 4 + 12 x 2 + 11 + 15 x 2+ 13 / 12
= 170 gram /12
= 14.16 gram.

Rewrite the equation in vertex form. (Include fractions in final answer).
y=-3x^2 -7x+4
For the given equation y = 3x² -7x + 4 the vertex form is given by
( 7/6, -1/12).
As given in the question,
Equation is given by :
y = 3x² -7x + 4
Standard form of the equation to get the vertex form is given by :
y = a ( x - h )² + k
Where ( h, k ) represents the vertex of the equation,
Now,
Simplify the given equation y = 3x² -7x + 4 into standard form to get vertex form,
y = 3x² -7x + 4
⇒ y = 3 [x² -2×(7/6)] + 4
⇒ y = 3 [ x² - 2×(7/6) + (49/36) - (49/36) ] + 4
⇒ y = 3 [ x² - 2×(7/6) + (49/36) ] - 3(49/36) + 4
⇒ y = 3 [x - (7/6)]² - (49/12) + 4
⇒ y = 3[x - (7/6)]² - (1/12)
Compare it with standard form ,
a = 3, h = (7/6) , k = -(1 /12)
Vertex form ( h, k) = ( 7/6 , -1/12 )
Therefore, for the given equation y = 3x² -7x + 4 the vertex form is given by ( 7/6, -1/12).
