Answer:
8 and 5
Step-by-step explanation:
----------------------------------------------------------
Given information
----------------------------------------------------------
Area = 3x² + 14x + 8
Length = x + 4
----------------------------------------------------------
Formula
----------------------------------------------------------
Area = Length x Width
----------------------------------------------------------
Find Width
----------------------------------------------------------
3x² + 14x + 8 = (x + 4) x width
width = (3x² + 14x + 8) ÷ (x + 4)
width = (x+4)(3x+2) ÷ (x + 4)
width = 3x + 2
----------------------------------------------------------
Answer: The width is 3x + 2 (Answer C)
----------------------------------------------------------
3 over 7, 2 over 5, 2 over 3 so your answer is b. this is the correct answer I think because1/2 equals one half 2/2 equals 1 whole hope you understand what I meanunderstand what I mean
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)
