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: -3
Explanation: In this problem, we're given the function f(x) = 2x + 1 and we're asked to find f(-2).
To find f(-2) or the value of the function or the value of the function when <em>x = -2</em>, we simply substitute -2 in for <em>x</em> in our function.
So we have f(-2) = 2(-2) + 1 or -4 + 1 which equals -3.
So f(-2) or the value of the function when x = -3 is -3.
