Answer:
Type A coffee in lbs = 97 lbs
Step-by-step explanation:
Type a = 4.55/lbs = x
type b = 5.70/lbs = y
Total in lbs = 147lbs
total in sales = 726.50
First,
x + y = 147 lbs -------------------equ 1
4.55x + 5.70y = lbs ------------ equ 2
<em>Multiply equ 1 by 4.55</em>
4.55x + 4.55y = 668.85 -------------equ 3
4.55x + 5.70y = 726.50 ------------equ 4
<em>Subtracting equ 3 from equ 4</em>
1.15y = 57.65
y = 50
<em>Substituting y = 50 into equ 1</em>
x + 50 = 147
x = 97
The population difference within the pair is normal.
The population distribution of mice with and without diabetes are identical.
mRNA population distribution for mice with diabetes is shifted relative to the population distribution for mice without diabetes.
Conclusion,
the two population has same shape , the two samples are independent simple random samples and the two samples are paired , the population means are the same .
Hence, each of the two population distribution is normal.

I would say D midpoint! Hope this helps :)
27/64 . because you do 3/4 to the third power (3x) which gives you that
