Answers
the earned interest after 3 years is $1,608.75.
What is simple interest?
Before delving further into the concept of simple interest, it is worth noting that it is a straightforward method for calculating interest on money, whereby interest is added at a constant rate for each time period and always to the initial principal amount. When we deposit our money into a bank, we can earn interest on our investment. Simple interest is one type of interest that banks may offer.
The formula for simple interest is:
I = P * r * t
where:
I = interest earned
P = principal (initial amount)
r = interest rate per year (as a decimal)
t = time (in years)
Substituting the given values, we have:
P = $9,750
r = 0.055 (since the interest rate is 5.5%)
t = 3
I = $9,750 * 0.055 * 3
I = $1,608.75
Therefore, the earned interest after 3 years is $1,608.75.

Do the data provide convincing statistical evidence that women pay more than men for the same transmission repair?
Answers
we do not have convincing statistical evidence that women pay more than men for the same transmission repair
How to determine if data provide convincing statistical evidence that women pay more than men for the same transmission repairTo determine whether the data provide convincing statistical evidence that women pay more than men we do not have convincing statistical evidence that women pay more than men for the same transmission repair for the same transmission repair, we can perform a hypothesis test.
Null hypothesis: The mean repair cost for women is the same as the mean repair cost for men.
Alternative hypothesis: The mean repair cost for women is greater than the mean repair cost for men.
We can use a two-sample t-test for the difference in means, assuming equal variances.
The test statistic is given by:
t = (xbar1 - xbar2) / (s_p * sqrt(1/n1 + 1/n2))
where xbar1 and xbar2 are the sample means, s_p is the pooled standard deviation, and n1 and n2 are the sample sizes.
The degrees of freedom is given by:
df = n1 + n2 - 2
Using the data given, we have:
xbar = 2542.86, xbar2 = 2469.29
s1 = 691.27, s2 = 599.77
n1 = n2 = 7
First, we can calculate the pooled standard deviation:
s_p = sqrt(((n1-1)*s1^2 + (n2-1)*s2^2) / (n1 + n2 - 2))
s_p = sqrt(((6)*691.27^2 + (6)*599.77^2) / (7 + 7 - 2))
s_p = 644.47
Then, we can calculate the t-statistic:
t = (xbar 1 1 - xbar2) / (s_p * sqrt(1/n1 + 1/n2))
t = (2542.86 - 2469.29) / (644.47 * sqrt(1/7 + 1/7))
t = 0.97
Using a t-distribution table with df = 12 and a significance level of 0.05, the critical value for a one-tailed test is 1.7823. Since our t-statistic is less than the critical value, we fail to reject the null hypothesis.
Therefore, we do not have convincing statistical evidence that women pay more than men for the same transmission repair

in one day a 20 pound dog eats 3 cups of food. How much would a 50 pound dog eat
Answers
Let x be the amount of food (in cups) that a 50 pound dog eats in one day.
Since the amount of food eaten is directly proportional to the weight of the dog, we can set up the following proportion:
20 pounds / 3 cups = 50 pounds / x cups
To solve for x, we can cross-multiply:
20 pounds * x cups = 3 cups * 50 pounds
20x = 150
x = 7.5
Therefore, a 50 pound dog would eat approximately 7.5 cups of food in one day, assuming that the amount of food eaten is directly proportional to the weight of the dog.
A scoop from a bin of assorted jelly beans contained a mix of flavors. root beer 5 licorice 22 cinnamon 6 What is the experimental probability that the next jelly bean scooped from the bin will be a cinnamon jelly bean? Write your answer as a fraction or whole number. P(cinnamon)=
Answers
Answer: The experimental probability of an event happening is defined as the number of times the event occurs divided by the total number of trials.
In this case, the number of cinnamon jelly beans in the scoop is 6. The total number of jelly beans in the scoop is 5+22+6=33.
Therefore, the experimental probability of scooping a cinnamon jelly bean from the bin is:
P(cinnamon) = number of cinnamon jelly beans / total number of jelly beans
P(cinnamon) = 6 / 33
P(cinnamon) = 2 / 11
So the experimental probability of scooping a cinnamon jelly bean from the bin is 2/11, which can be written as a fraction.

Step-by-step explanation:
Question 1 :
The statement that best describes the solutions of a two-variable equation is (1) The ordered pairs must lie on the graphed equation. This means that any ordered pair (x,y) that satisfies the equation will corresponds to a point on the graph of the equation. In other words, if we plot all the points (x,y) that make the equation true, we will obtain the graph of the equation. Any points that do not lie on the graph is not a solution to the equation. Therefore, when solving a two-variable equation, we need to find the values of x and y that make the equation true and plot those points on the graph to visualize the solutions.
Question 2 :
To use the arithmetic sequence formula, we need to know the first term (a1), the common difference (d), and the desired term (an). In this case, we are given the first term as 4 and the common difference as 3 (since each term is increasing by 3). To find the 10th term, we would replace the variable "n" with 10 in the formula. Therefore, to determine the 10th term of this sequence, we would use the formula:
a10 = a1 + (n-1)d
a10 = 4 + (10-1)*3
a10 = 4 + 27
a10 = 31
Thus, the 10th term of the given sequence is 31.
Question 3 :
The formula an = al + (n-1)d is used to determine the nth term in an arithmetic sequence, where "a" represents the first term in the sequence, "n" represents the term number being solved for, and "d" is the common difference between terms. The formula essentially states that to find any term in an arithmetic sequence, one must add the common difference between terms multiplied by the number of terms-1 to the value of the first term. This formula can be applied to various situations, such as determining the total cost of goods sold in a business with a constant markup percentage, or calculating the number of days it will take to save a given amount of money with a fixed monthly contribution. By understanding the principles behind the formula, individuals can successfully solve problems involving arithmetic sequences in a variety of contexts.

Answers
Answer:
the product of (3-2x)(2x+1)(x-5) is -4x^3 + 26x^2 - 19x - 75.
Step-by-step explanation:
To find the product, we need to multiply these three expressions:
(3 - 2x)(2x + 1)(x - 5)
Let's start by multiplying the first two expressions using the distributive property:
(3 - 2x)(2x + 1) = 6x - 4x^2 + 3 - 2x
Now we can multiply this result by the third expression using the distributive property again:
(6x - 4x^2 + 3 - 2x)(x - 5) = 6x^2 - 34x + 15x - 75 - 4x^3 + 20x^2
Simplifying this expression by combining like terms, we get:
-4x^3 + 26x^2 - 19x - 75
Therefore, the product of (3-2x)(2x+1)(x-5) is -4x^3 + 26x^2 - 19x - 75.

PQ = √[(Qx - Px)² + (Qy - Py)²]
= √[(-3 - (-5))² + (6 - 7)²]
= √[4 + 1]
= √[5]
RS = √[(Sx - Rx)² + (Sy - Ry)²]
= √[(-8 - (-6))² + (2 - 0)²]
= √[4 + 4]
= √[8]
Since PQ and RS are not equal, we need to find a point S such that PQRS has equal sides. Moreover, the diagonals of a rectangle bisect each other. Hence, we can use the midpoint formula to find a point that bisects PR:
M = [(-5 - 6)/2, (7 + 0)/2]
= (-11/2, 7/2)
Let's consider each option:
a.) S(-4,-1)
The slope of PQ is (6 - 7)/(-3 + 5) = -1/2, so the slope of RS must be -1/2 as well. The slope of RS is (2 - 0)/(-8 + 6) = 1, so S(-4, -1) cannot be a point of RS.
b.) S(-7,2)
The slope of PQ is (6 - 7)/(-3 + 5) = -1/2, so the slope of RS must be -1/2 as well. The slope of RS is (2 - 0)/(-7 + 6) = -2, so S(-7, 2) cannot be a point of RS.
c.) S(-8,2)
The slope of PQ is (6 - 7)/(-3 + 5) = -1/2, so the slope of RS must be -1/2 as well. The slope of RS is (2 - 0)/(-8 + 6) = 1, so S(-8, 2) could be a point of RS. Moreover, the distance from S to the midpoint of PR is:
√[(-11/2 - (-8))² + (7/2 - 2)²]
= √[25/4 + 9/4]
= √[34]/2
This is equal to the length of PQ, so PQRS could be a rectangle with S(-8, 2).
d.) S(-8,1)
The slope of PQ is (6 - 7)/(-3 + 5) = -1/2, so the slope of RS must be -1/2 as well. The slope of RS is (1 - 0)/(-8 + 6) = -1, so S(-8, 1) cannot be a point of RS.
Therefore, the answer is option c.) S(-8,2).

In a circle ABCD, OB = 10 cm. Find the measure of AC.
Answers
The measure of AC, in circle ABCD can be found to be 20 cm.
How to find the measure?In Circle ABCD, O is the midpoint of the circle which means that OB is the radius.
As A and C are on opposite sides of the circle, it means that the value of the measure of AC would be the diameter of the circle which can be found if we have the radius.
The diameter which is AC would then be:
= Radius x 2
= OB x 2
= 10 x 2
= 20 cm
In conclusion, the measure of AC is 20 cm.

determine if (4,1) is a solution for the system of equations
y=-1x+5
y=2x-7
Answers
Answer: The point (4, 1) is a solution to this system of equations.
Step-by-step explanation:
To determine if (4, 1) is a solution to this system, you must plug it in to both of the equations. It is in the form of (x, y); so x = 4, and y = 1
Equation #1: y = -x + 5
1 = -(4) + 5
1 = 1 <————— This is part of the solution to this equation.
Equation #2: y = 2x - 7
1 = 2(4) - 7
1 = 8 - 7
1 = 1 <———- This is part of the solution to this equation.
The point (4, 1) is a solution to this system of equations.
A line passes through the point (-4, -3) and has a slope of 5.
Write an equation in slope intercept form for this line.
Answers
The equation of the line is y=5x+17.
What is slope intercept form of the equation?
When the slope of the line being studied is known, and the provided point is also the y intercept, the slope intercept formula, y = mx + b, is utilised (0, b). It provides both a slope and an intercept, which is why the form is known as the slope-intercept form.
Here the given the point [tex](x_1,y_1)=(-4,-3)[/tex] and slope m = 5.
Now using equation formula then,
=> [tex]y-y_1=m(x-x_1)[/tex]
=> y -(-3)=5(x-(-4))
=> y+3 = 5(x+4)
=> y+3 = 5x+20
=> y = 5x+20-3
=> y = 5x+17
Hence the slope intercept form of the equation is y = 5x+17.
