Answer:
3u-15
Step-by-step explanation:
3(u-5)
Just multiply 3 by both of the numbers inside the parentheses and we get: 3u-15
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:
177 sq ft
Step-by-step explanation:
Big square = 169
4+4 = 8
13-8 = 5•1.6 = 8
Little square = 8
169+8 =177
Answer:
Step-by-step explanation:
just replace the x by the number given, it's simple calculation
6c^2-5d+8
6 (5)^2-5(4)+8
30^2-20+8
900-20=8
880-8=872
ANSWER:872
