Volume = length x width x height
Thus, you need to find the cubic root of 500....the number that when multiplied by itself three times = 500,
There are different ways to write this.
![\sqrt[3]{500}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B500%7D%20)
=
![\sqrt[3]{125 * 4}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B125%20%2A%204%7D%20)
= 5
![\sqrt[3]{4}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B4%7D%20)
You can also show it as a decimal using a calculator = 7.94
Let X be a discrete binomial random variable.
Let p = 0.267 be the probability that a person does not cover his mouth when sneezing.
Let n = 18 be the number of independent tests.
Let x be the number of successes.
So, the probability that the 18 individuals, 8 do not cover their mouth after sneezing will be:
a) P (X = 8) = 18! / (8! * 10!) * ((0.267) ^ 8) * ((1-0.267) ^ (18-8)).
P (X = 8) = 0.0506.
b) The probability that between 18 individuals observed at random less than 6 does not cover their mouth is:
P (X = 5) + P (X = 4) + P (X = 3) + P (X = 2) + P (X = 1) + P (X = 0) = 0.6571.
c) If it was surprising, according to the previous calculation, the probability that less than 6 people out of 18 do not cover their mouths is 66%. Which means it's less likely that more than half of people will not cover their mouths when they sneeze.
Step-by-step explanation:
1\5 ÷3/7=7/15
3/7 multiply by 7/15=1/5

Step-by-step explanation:
Answer:
4
Step-by-step explanation:
if the area is 1/4 that would mean that the sides are equal to 1/2. if you stretch 1/2 out 4 times longer that would be equal to 2. 2 x 2 = 4
