Savannah is being charged a simply interest rate of ______.
Answers
Step-by-step explanation:
To find the simple interest rate that Savannah is being charged, we can use the formula for simple interest:
I = P * r * t
where I is the total interest paid, P is the principal (the amount borrowed), r is the interest rate, and t is the time period over which the interest is paid.
Since Savannah must pay back the $2,900.00 principal plus a $1,375.00 fee, the total interest paid is $1,375.00. The time period is 8 months, which is equal to 8/12 = 2/3 of a year. Substituting these values into the formula and solving for r, we get:
$1,375.00 = $2,900.00 * r * (2/3)
r = $1,375.00 / ($2,900.00 * (2/3)) = 0.1429
This is the interest rate that Savannah is being charged. To express this rate as a percentage, we can multiply it by 100% to get:
r = 0.1429 * 100% = 14.3%
Therefore, Savannah is being charged a simple interest rate of approximately 14.3%.

A one-factor ANOVA is used to evaluate the mean differences among four treatment conditions with a sample of n = 12 participants in each group. For this study, what is dfwithin treatments?
Answers
In this case, with four treatment groups and n = 12 participants in each group, dfwithin treatments would be equal to 3, because there are 4 - 1 = 3 treatment groups.
In a one-factor ANOVA, dfwithin treatments refers to the degrees of freedom within the treatment groups, which is a measure of the amount of variability that is present within each group.
The degrees of freedom within the treatment groups is used to calculate the mean square within treatments (MSwithin), which is a measure of the variability within each group. MSwithin is calculated by dividing the sum of the squared differences between each participant's score and the group mean by dfwithin. This value is then used to determine the statistical significance of the treatment effects, by comparing it to the mean square between treatments (MSbetween), which is a measure of the variability between the treatment groups.
In a one-factor ANOVA, the total degrees of freedom is equal to the number of participants in all of the groups combined (4 groups * 12 participants per group = 48) minus the number of groups (48 - 4 = 44). The degrees of freedom between treatments is equal to the number of groups minus 1 (4 - 1 = 3), and the degrees of freedom within treatments is equal to the total degrees of freedom minus the degrees of freedom between treatments (44 - 3 = 41).

An insurance company is reviewing its current policy rates. When originally setting the rates they believed that the average claim amount was $1,800. Now there are concerns that if the true mean is actually higher than this they could potentially lose a lot of money. They randomly select 40 claims, and calculate a sample mean of $1,950. Assuming that the standard deviation of claims is $500, and set significance level = :05, test to see if the insurance company should be concerned.
Answers
So, the insurance company should be concerned that they could potentially lose money.
To test whether the insurance company should be concerned about the true mean claim amount being higher than the original estimate of $1,800, we can perform a one-sample t-test.
The null hypothesis for this test is that the true mean claim amount is equal to the original estimate of $1,800, and the alternative hypothesis is that the true mean claim amount is greater than the original estimate.
The t-statistic for this test is calculated as follows:
t = (sample mean - null mean) / (standard deviation / sqrt(sample size))
Plugging in the values from the problem, we have:
t = ($1,950 - $1,800) / ($500 / sqrt(40)) = 2.5.
We can then use a t-table or a computer to find the critical value of t for a one-tailed t-test with 39 degrees of freedom and a significance level of 0.05. The critical value is 1.68.
Since the calculated t-value of 2.5 is greater than the critical value, we can reject the null hypothesis and conclude that the true mean claim amount is significantly greater than the original estimate of $1,800.
Therefore, the insurance company should be concerned that they could potentially lose money.

Step-by-step explanation:
For a degrees since 72 degrees and a degrees make a straight angle:
180-72= a
So, a=108 degrees
Same goes for b degrees:
180-92=b
So, b=88 degrees
For c degrees, you need to know that the sum of the angles in a quadrilateral equal to 360 degrees.
So, 74+a+b+c=360

Mean = 95.125
Variance = 198.90625
Standard deviation = 14.06,
Confidence interval = 95.125 +/- 3.45
To find the 95% confidence interval of the mean score for all bowlers in this league, we need to first calculate the sample mean and sample standard deviation of the given data set.
The sample mean is calculated as follows:
mean = (96 + 103 + 94 + 105 + 91 + 101 + 99 + 89 + 94 + 91 + 82 + 94 + 97 + 99 + 89 + 107 + 97 + 100 + 96 + 92 + 96 + 95 + 99 + 90 + 84 + 97 + 99 + 87 + 102 + 92 + 91 + 90 + 88 + 103 + 94 + 90 + 98 + 91 + 87) / 40mean = 95.125
The sample standard deviation is calculated as follows:
First, we need to calculate the variance of the data set, which is done by taking the sum of the squared differences between each score and the mean, and dividing by the sample size minus 1:
variance = ((96 - 95.125)^2 + (103 - 95.125)^2 + (94 - 95.125)^2 + (105 - 95.125)^2 + (91 - 95.125)^2 + (101 - 95.125)^2 + (99 - 95.125)^2 + (89 - 95.125)^2 + (94 - 95.125)^2 + (91 - 95.125)^2 + (82 - 95.125)^2 + (94 - 95.125)^2 + (97 - 95.125)^2 + (99 - 95.125)^2 + (89 - 95.125)^2 + (107 - 95.125)^2 + (97 - 95.125)^2 + (100 - 95.125)^2 + (96 - 95.125)^2 + (92 - 95.125)^2 + (96 - 95.125)^2 + (95 - 95.125)^2 + (99 - 95.125)^2 + (90 - 95.125)^2 + (84 - 95.125)^2 + (97 - 95.125)^2 + (99 - 95.125)^2 + (87 - 95.125)^2 + (102 - 95.125)^2 + (92 - 95.125)^2 + (91 - 95.125)^2 + (90 - 95.125)^2 + (88 - 95.125)^2 + (103 - 95.125)^2 + (94 - 95.125)^2 + (90 - 95.125)^2 + (98 - 95.125)^2 + (91 - 95.125)^2 + (87 - 95.125)^2) / (40 - 1)variance = 198.90625
The sample standard deviation is then the square root of the variance:
standard deviation = sqrt(198.90625)
standard deviation = 14.06
Now that we have the sample mean and sample standard deviation, we can use these values to calculate the 95% confidence interval of the mean score for all bowlers in this league.
We can use the following formula to calculate the confidence interval:
confidence interval = mean +/- (1.96 * (standard deviation / sqrt(sample size)))
Substituting in the values we calculated above, we get:
confidence interval = 95.125 +/- (1.96 * (14.06 / sqrt(40)))
Hence , confidence interval = 95.125 +/- 3.45

Barnes and no ble and are on sale for 35gat target. If you have a 25.1.
off Coupon for Barnes and noble and a 51. Red card discount at target,
find what the price before tax would be at each of the two
retailers.
Answers
The price before tax of the books at Barnes and Noble would be 44$ - 25.1$ = 18.9$ if you use your coupon.
The price before tax of the books at Target would be 35$ - 51.1$ = -16.1$ if you use your Red card discount. However, the final price of the books cannot be negative, so the price before tax of the books at Target would be 35$ if you use your Red card discount.
Using substitution to solve the following system of linear equations, what is the y-coordinate for the solution? 6x + y = -32 y = x - 4 Select one:a. y = -8b. y = 8c. y = 2d. y = -4
Answers
Therefore , the answer to this problem is that y-coordinate for the solution is option a) y = -8
What does equation mean?A number, a variable, or a mix of both are used in an expression coupled with specific operation symbols. An equal sign is used to denote the division of two expressions that make up an equation.
Here,
6x + y = -32 and
y = x - 4
=> 6x +( x - 4) = -32
=>7x -4=-32
=>7x =-28
=> x = -4
Thus,
y = -4 - 4 = -8
Therefore , the y-coordinate comes out to be y = -8
Thus, the correct option in the following option is option a)y=-8.

When planning a more strenuous hike, Brett figures that he will need at least 0.5 liters of water for each hour on the trail. He also plans to always have at least 1.80 liters of water as a general reserve. If x represents the duration of the hike (in hours) and y represents the amount of water needed (in liters) for a hike, the following inequality describes this relation: y> 0.5x + 1.8 Which of the following would be a solution to this situation?
a.) Having 3 liters of water for 4.5 hours of hiking
b.) Having 2 liters of water for 2.5 hours of hiking
c.) Having 4.5 liters of water for 4 hours of hiking
d.) Having 2.5 liters of water for 3 hours of hiking
Answers
Option C is correct,4.5 is greater than 3.8, so this solution does work.
If x represents the number of hours and y represents the number of liters of water, then we can plug the possible solutions into our inequality to see which solution(s) work.
Inequality
In mathematics, an inequality is a relation that makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.
The first option is having 0.5 liters of water for 4.5 hours of hiking. So will plug 3 in for y and 4.5 in for x:
y > 0.5x + 1.8
3 > 0.5(4.5) + 1.8
3 > 4.05
But 3 is not greater than 4.05, this solution does not work.
The next option is having 2 liters of water for 2.5 hrs of hiking:
2 > 0.5(2.5) + 1.8
2 > 3.05
But 2 is not greater than 3.05, so this solution does not work.
Option c is having 4.5 liters of water for 4 hours of hiking:
4.5 > 0.5(4) + 1.8
4.5 > 3.8
So 4.5 is greater than 3.8, this solution does work.
The last option is having 2.5 liters of water for 3 hours of hiking:
2.5 > 0.5(3) + 1.8
2.5 > 3.3
2.5 is not greater than 3.3, so this solution does not works
Option c is correct,4.5 is greater than 3.8 so this solution does work.

find a direct relationship between x and y.
x=t-5 and y=t^2-6t
Answers
The direct relationship of the variables is y = (t^2 - 6t)/(t - 5) * x
How to determine the direct relationship?From the question, we have the following parameters that can be used in our computation:
x = t - 5 and y = t^2 - 6t
The direct relationship between x and y is calculated using
Y = (y/x) * X
Substitute the known values in the above equation, so, we have the following representation
y = (t^2 - 6t)/(t - 5) * x
Hence, the direct relationship is y = (t^2 - 6t)/(t - 5) * x

Think of two numbers that multiply to -24, but add to -14.
Answers
Answer:
x = -7 + √(73)
y = -7 - √(73)
Step-by-step explanation:
Product p = x × y = -24
Somme s = x + y = -14
Then
x and y are solutions to the equation:
z² - sz + p = 0
Then
x and y are solutions to the equation:
z² + 14z - 24 = 0
Using the quadratic formula:
x = ( -14 + √[(14² - 4×(1)×(-24)] ) / ( 2×(1) ) = -7 + √(73)
and
y = ( -14 - √[(14² - 4×(1)×(-24)] ) / ( 2×(1) ) = -7 - √(73)
