Answer:
(16√75)/(5√12) = 8
Step-by-step explanation:
The hypothesis test shows that we reject the null hypothesis and there is sufficient evidence to support the claim that the return rate is less than 20%
<h3>What is the claim that the return rate is less than 20% by using a statistical hypothesis method?</h3>
The claim that the return rate is less than 20% is p < 0.2. From the given information, we can compute our null hypothesis and alternative hypothesis as:


Given that:
Sample size (n) = 6965
Sample proportion 
The test statistics for this data can be computed as:



z = -2.73
From the hypothesis testing, since the p < alternative hypothesis, then our test is a left-tailed test(one-tailed.
Hence, the p-value for the test statistics can be computed as:
P-value = P(Z ≤ z)
P-value = P(Z ≤ - 2.73)
By using the Excel function =NORMDIST (-2.73)
P-value = 0.00317
P-value ≅ 0.003
Therefore, we can conclude that since P-value is less than the significance level at ∝ = 0.01, we reject the null hypothesis and there is sufficient evidence to support the claim that the return rate is less than 20%

This In Expression Form Is:
3r + 4t.
The Reason Why Is Because:
When You Triple r, That Is 3r, And When You Quadruple t, It becomes 4t. And Plus Means to Add. So, This Becomes 3r + 4t
I Hope this Helps!
Answer:
(2, −1)
(5, 2)
Step-by-step explanation:
{(−2, 5), (−1, 2), (0, 1), (2, 5)}
To find the inverse of the given points , swap the x and y values
Because x become the y value of inverse and y becomes the x value of inverse
(-2,5) becomes (5,-2)
(-1,2) becomes (2,-1)
(0,1) becomes (1,0)
(2,5) becomes (5,2)
The point of the inverse function are
(5,-2) (2,-1) (1,0) and (5,2)
option B and C are correct
