Answer:
E = 56
Step-by-step explanation:
Given that E varies directly with 
then the equation relating them is
E = k ← k is the constant of variation
To find k use the condition E = 40 when C = 25
k = 
= 
= 
= 8, thus
E = 8 ← equation of variation
When C = 49, then
E = 8 × 
= 8 × 7 = 56

Answer:
x= -1/3 or -0.3
Step-by-step explanation:
Answer:
a. 8.95
b. it is
c. yes it belongs
d. males are 2.574 taller than females on average.
Step-by-step explanation:
GIven the regression outpuit that we have in this question, the value of the t test statistics for the shoe size can be solved as
a. test statistic = 1.164/0.13
t test = 8.95
b. the regression coefficient of shoe size is 1.164, this is statistically significant
c. Yes the variable shoe size does belong to the model.
d. The regression coefficient of gender shows that on the average, while holding other variables constant, males are 2.574 inches taller than the their female counterparts.
