Answer:
20 ft
Step-by-step explanation:
The ratio of object height to shadow length is (6 ft)/(1.5 ft) = 4.
The object is 4 times as tall as its shadow is long, so the pole is 4×5 ft = 20 ft tall.
This answer is pretty simple.
Since there are 3 yards of ribbon, and you need to make ____ number of pieces with each 1/4 long
To do this you divide.
3 divided by 1/4
The answer is 12
4/3 (k)(k + 7)(3k + 9)
4/3 (k)(3k^2 + 9k + 21k + 63)
4/3 (k)(3k^2 + 30k + 63)
4/3 (3k^3 +30k + 63)
4k^3 +40k +84
Answer:
3.625
Step-by-step explanation:
Given a normal distribution :
Average weight = population mean = 172 pounds
Population standard deviation = 29 pounds
Number of samples selected(n) = 64
The standard deviation of the sample also called the standard error is the proportion of the population standard deviation to the square root of the number samples.
Sample standard deviation :
Population standard deviation /√n
= 29 /√64
= 29 / 8
= 3.625
