3y+6 is the answer
-9+5(y+3)-2y
-9+5y+15-2y
-9+3y+15
=3y+6
Answer:
a) 25
b) 49
c) 97
Step-by-step explanation:
The sample size is calculated using the formula, n = 
Now,
for 95% confidence level value of z-factor = 1.96
Given:
Mean = $3.94
standard deviation = $0.25
thus,
a) for margin of error = $0.10
n = 
or
n = 
or
n = 4.9²
or
n = 24.01 ≈ 25 (Rounded off to next integer)
b) for margin of error = $0.07
n = 
or
n = 
or
n = 7²
or
n = 49
c) for margin of error = $0.05
n = 
or
n = 
or
n = 9.8²
or
n = 96.04 ≈ 97 (Rounded off to next integer)
The answer is A. Y=square root of 2x
Answer:
Hey!
Your answer is 44!
Step-by-step explanation:
Here's how...
x+(x+2)+(x+4)+(x+6)+(x+8)=200
5x+20=200 (minus 20 on both sides to get 5x by itself)
5x=180 (divide both sides by 5 to get just x)
x=36
5th number - x+8=36+8=44 (simple substitution and addition)
