Answer:
Step-by-step explanation:
Given that X, the number of square feet per house is N(mean, 137)
Sample size = 19
Sample mean x bar =1350 sq ft
Since population std dev is given,
std error of sample = 
Since sample size is small, t critical value can be used
df = 18
t value for 80% two tailed = 1.333
Margin of error = ±1.333(std error) = ±
Confidence interval = sample mean ±margin of error
= 
Answer:
0.15
Step-by-step explanation:
Answer:
1,015
Step-by-step explanation:
7 pounds of honey equals 1 pound of wax
So if we have 145 pounds of was, we multiply 145 by 7
145x7= 1,015
Answer:
A
Step-by-step explanation:
on the left of the equation, (6^4)^-5 = 6^-20
the right side you add the exponents so it would be (-7-3) =-10
so it would be 6^-10, which is greater than 6^-20
If you mean just any fraction in the world that isn't equivalent to 1/3, then 5/6 7/9 and 2/10 would work
Hope this helps! Good Luck!
