Answer:
d. 75,595
Step-by-step explanation:
Given the estimated regression equation :
y=550 + 30x1 + 9x2
if number of items made (x) = 2500 ; number of stores stocking the product (x2) = 5
Predicted profit (y) will be :
Substitute the values x1 = 2500 and x2 = 5 into the estimated regression model:
y=550 + 30(2500) + 9(5)
y = 550 + 75000 + 45
y = 75595
Hence, the predicted profit will be 75,595
Answer:
n = 86
Step-by-step explanation:
Step 1: Write equation
41 + n = 127
Step 2: Subtract 41 on both sides
n = 86
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
41 + 86 = 127
127 = 127

Answer:


Step-by-step explanation:
Given that A perfume company claims that the mean weight of ther new perfume is at least 8.9 fluid oz
For testing this claim, in Statistics we perform a certain measures called hypothesis testing.
For this first step is to create null and alternate hypothesis.
Normally null hypothesis would have some statistic = something
Here we want to test the mean weight of perfume
Hence null hypothesis would be
H0: mu = 8.9 fl oz.
Alternate hypothesis would be opposite of this claim
i.e.
Ha: mu ≠8.9 fluid oz
Hence answer is


We know that the sum of all angle measures in a trapezoid is 360* (* means degrees)
Therefore we can construct the equation
(X+28)+(x)+(4x-14)+(4x-14)= 360
Now add like terms
10x = 360
And divide by the coefficient of X (aka 10)
X= 36
