Answer:
2.5
Step-by-step explanation:
By Pythagoras theorem,
Hypotenuse = √( 4^2 + 3^2 )
= √( 16 + 9 )
= √25
Hypotenuse = 5
4 / 2 = 5 / x
2 = 5 / x
x = 5 / 2
x = 2.5
Assume that a simple random sample has been selected from a normally distributed population. Find the test statistic t.
Test the claim that the mean lifetime of a particular car engine is greater than 220,000 miles. Sample data are summarized as n = 23, x-bar = 226,450 and s=11,500. Use a significance level of 5%. Determine the p-value.

Answers
Using the t-distribution, it is found that the p-value of the test is 0.007.
At the null hypothesis, it is tested if the mean lifetime is not greater than 220,000 miles, that is:
[tex]H_0: \mu \leq 220000[/tex]
At the alternative hypothesis, it is tested if the mean lifetime is greater than 220,000 miles, that is:
[tex]H_1: \mu > 220000[/tex].
We have the standard deviation for the sample, thus, the t-distribution is used. The test statistic is given by:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean. [tex]\mu[/tex] is the value tested at the null hypothesis. s is the standard deviation of the sample. n is the sample size.For this problem:
[tex]\overline{x} = 226450, \mu = 220000, s = 11500, n = 23[/tex]
Then, the value of the test statistic is:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{226450 - 220000}{\frac{11500}{\sqrt{23}}}[/tex]
[tex]t = 2.69[/tex]
We have a right-tailed test(test if the mean is greater than a value), with t = 2.69 and 23 - 1 = 22 df.
Using a t-distribution calculator, the p-value of the test is of 0.007.

Nancy sold tickets to a school play. She sold $426 worth of tickets. She sold 8 more adult tickets than children tickets and 3 times as many senior tickets than children tickets. If children tickets are $3, senior tickets are $4 and adult tickets are $6, how many adult tickets did Nancy sell
Answers
Answer:
So number of Adult tickets sold = A = 26.
Step-by-step explanation:
Define A, C, S as
A = number of adult tickets,
C = number of children tickets,
S = number of Senior tickets.
Then, by the statement of the problem, we have that
A = 8 + C,
S = 3C,
3C + 4S + 6A = 426,
so that
3C + 4(3C) + 6(8 + C) = 426
3C + 12C + 48 + 6C = 426
21C + 48 = 426
7C + 16 = 142
7C = 126
C = 126/7 = 18
A = 8 + 18 = 26
S = 3(18) = 54

What is the answer X=-2(6+4)
Answers
Answer:
X = -20
Step-by-step explanation:
X = -2(6+4)
^ add 6 and 4 together first because they are in parentheses
-2(10)
^ this parenthesis means you want to multiply -2 and 10
because 2 x 10 = 20
that must mean -2 x 10 = -20
therefore, the value of X is -20
X= -20

Answers
Answer:
yes
Step-by-step explanation:
The perimeter of the rectangle ABCD and WXYZ are 14 units and 28 units respectively. The perimeter of the rectangle ABCD and WXYZ are 12 units² and 48 units² respectively.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The perimeter of a rectangle = 2(L+W)
The vertices of two rectangles are A(−5,−1),B(−1,−1),C(−1,−4),D(−5,−4) and W(1,6),X(7,6),Y(7,−2),Z(1,−2).
As per the given data, the figure of two rectangles has been attached below.
According to the graph,
The perimeter of the rectangle ABCD = 2(3 + 4) = 2(7) = 14 units
The perimeter of the rectangle WXYZ = 2(6 + 8) = 2(14) = 28 units
The area of the rectangle ABCD = (3 × 4) = 12 units²
The area of the rectangle WXYZ = (6 × 8) = 48 units²
The rectangles are similar because the ratio of length to width is equivalent.
The perimeter of the rectangle ABCD and WXYZ are 14 units and 28 units respectively. The perimeter of the rectangle ABCD and WXYZ are 12 units² and 48 units² respectively.

Answers
Answer:
Domain: {0,1,2,4}
Range: {0, 1, 4, -6}
Step-by-step explanation:
Hi there!
The domain is the set of all x-values in a relation.
{(0,0),(1,1),(2,4),4,-6)}
The x-values are 0, 1, 2, and 4.
Domain: {0,1,2,4}
The range is the set of all y-values in a relation.
{(0,0),(1,1),(2,4),4,-6)}
The y-values are 0, 1, 4 and -6.
Range: {0, 1, 4, -6}
A function occurs when there is only one y-value for every x-value. This is the case for this relation, so therefore it is a function.

She paid $ 76,800 as down payment, the original amount financed was $ 243,200, her monthly payment was $ 2,919.71, and the total amount she will spend on this home is $ 1,127,896.38.
Given that Jenelle bought a home for $ 320,000, paying 24% as a down payment, and financing the rest at 5% interest for 30 years, to determine how much money did Jenelle pay as a down payment, what was the original amount financed, what is her monthly payment, and the total amount of money she will spend on this home, the following calculations must be made:
320,000 x 0.24 = Down payment 76,800 = Down payment 243,200 x 1.05 ^ 30 = X 243,200 x 4.32 = X 1,051,096.38 = X 1,051,096.38 / (30 x 12) = X 2,919.71 = X 1,051,096.38 + 76,800 = 1,127,896.38
Therefore, she paid $ 76,800 as down payment, the original amount financed was $ 243,200, her monthly payment was $ 2,919.71, and the total amount she will spend on this home is $ 1,127,896.38.
