The question is incomplete. The complete question is :
The National Coffee Association reported that 62% of U.S. adults drink coffee daily. A random sample of 225 U.S. adults is selected. Round your answers to at least four decimal places as needed.
Required:
a. Find the mean μ.
b. Find the standard deviation σ.
c. The standard deviation σ.
Solution :
a). Percentage of the US adults who drinks coffee daily = 62%
Therefore, the mean, μ = 0.62
b). We know, p = μ = 0.62
And n = 225
Therefore, the standard deviation is given by :
c). Standard deviation, σ = 0.0324
Answer: 5n-6=39;n=9
Step-by-step explanation:
The product of: indicates multiplication
A number: indicates you need a variable (n)
And five: indicates what your multiplying (5)
Decreased by six: indicate your subtracting 6
Is thirty nine: indicates your answer is 39
Now solve using inverse operations
5n-6=39
<u> +6 +6</u>
<u>5n</u>=<u>45</u>
5 5
n=9
Length = 5x
width = x
area = 125
A = L*W
125 = (5x)(x)
125 = 5x^2
125/5 = x^2
25 = x^2
sqrt{25} = sqrt{x^2}
5 = x
The width is 5 feet.
The length is 5 times 5 feet or 25 feet.
To find the perimeter, we use P = 2L + 2W.
P = 2(25) + 2(5)
P = 50 + 10
P = 60 feet.
Done!
F(10) = (10)^2 + 1
= 100 + 1
= 101
101 is the answer
Answer:
3/35
Step-by-step explanation:
2/5 ÷ 14/3
2/5 × 3/14
= 3/35
