Answer:
The mean is μ = 15.2 and the standard deviation is σ = 0.9. Find the probability that X is greater than 15.2. Write your answer as a decimal rounded to 4 places.
The mean is μ = 15.2 and the standard deviation is σ = 0.9.
Find the probability that X is between 14.3 and 16.1.
Write your answer as a decimal rounded to 4 places.

Answer:
8 quarters
Explanation:
Let's look at the ratio first off.
2 quarters: 4 dimes: 7 nickels
Let's write it in terms of money
50 cents of quarters: 40 cents of dimes: 35 cents of nickels
If we add up all the cents then we get $1.25
Then, if we divide $5 by $1.25 we get 4.
You should then multiply the original ratio by 4:
8 quarters: 16 dimes: 28 nickels
Let's check this by turning it to money:
$2: $1.60: $1.4
This all adds up to $5
Therefore your answer is 8 quarters.

Answer:
P=380 ft.
Explanation:
Area=length x width
Perimeter= 2*length + 2*width
Width= 4*length + 8
A=5472 ft²
5472= l * (4l +8) (plug in values)
5472 = 4l² +8l (simplify)
4l² + 8l - 5472 = 0 (subtract 5472)
4(l² + 2l -1368) = 0 (factor out a 4)
4(l +38)(l-36)=0 (factor)
l=36 ft. (-38 is extraneous because it is negative)
5472=38*w
w=152 ft.
P=2(38) + 2(152)
P= 380 ft.
