Answer:
A one-sided, two-sample t-test
Step-by-step explanation:
In the context, the values of the population standard deviations are not provided, therefore we have to use the two sample t tests for the difference between the two population means. This claim for the hypothesis or the alternative hypothesis is given as the average selling price is more for the first group of the sample size of 21 as compared to the other group of the sample size of 87. Therefore, we perform an one sided test or the upper tailed test.
244 divided by 60 = 4.0666
c. (x + 5)(x - 7) use the FOIL method.
x² + 5x - 7x - 35
x² + (5x - 7x) - 35 collect like terms.
x² - 2x - 35
hope that helps, God bless!
Answer: M = 
Step-by-step explanation:
M (x + y) + 4y = x + 2y (Multiply 
in both sides)
M (x + y) = x + 2y - 4y
M (x + y) = x - 2y (Divide (x+y) from both sides)
M =
Answer:
B, A, C, I
Step-by-step explanation:
1. y= -2x-7
2. y= -1/3x +0
3. y= -2x-4
4. y= -1/3x-1
This is what I got, is the code supposed to make a word?
