Make them equal to each other because they are vertical angles.
6x-4=5x+5
x=9
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 answer is 32%
Step-by-step explanation:
steps)7-2n=3
then you move the constant to tge right hand side and change its sign
-2n=3-7
then
calculate the difference
-2n=3-7
-2n= -4
Divide both sides
n=2
