The number of days that the eggs took in hatching is 54 days.
Given that mean is 50, standard deviation is 2 and confidence level is 95% and sample size is 35.
We are required to find the number of days it took to hatch the eggs.
We have to apply the z statistics because sample size is greater than 30.
Z=(X-μ)/σ, in which μ is mean and σ is standard deviation.
Z score for the confidence level 95% is 1.96.
1.96=(X-50)/2
3.92=X-50
X=50+3.92
X=53.92
X=54 (After approximation)
Hence the number of days that the eggs took in hatching is 54 days.

Answer:
The print is 18 inches longer then it is wide
Step-by-step explanation:
I multiplied 12 x 4 becuase there are 12 inches in a foot to get 48 inches. So the print is 48 inches long. Then I multiplied 2 times 12 to get 24 and then 24+6 + 30 so the rug is 30 inches wide. Finally I subtracted 30 from 48 to get the diffrence in inches. Which is 18 :)
Option B:
The linear equation that best describes the model is y = 40x + 800.
Solution:
Take two points which exactly on the line.
Let the points are (0, 800) and (10, 1200).

Slope of the line:



m = 40
y-intercept of the line is where the line crosses at y-axis.
y-intercept (b) = 800
Equation of a line:
y = mx + b
y = 40x + 800
The linear equation that best describes the model is y = 40x + 800.
Option B is the correct answer.
