Answer:
The probability that a randomly selected monthly cell phone bill is less than $95 is 0.9772
Step-by-step explanation:
The average monthly household cellular phone bill is $73.
Local monthly household cell phone bills are normally distributed with a standard deviation of $11.
We are supposed to find the probability that a randomly selected monthly cell phone bill is less than $95 i.e.P(x<95)
Z=2
Refer the z table for p value
So,p value = 0.9772
Hence the probability that a randomly selected monthly cell phone bill is less than $95 is 0.9772
Answer:
1. 45
2. 24
3. 32
Step-by-step explanation:
One
Ashley= 3/4 * Steve
Ashley= 3/4 * 60
Ashley = 180/4
Ashley = 45
Two
60% of 40
60/100 * 40
2400/100 = 24
Three
40% 80 = 40/100 * 80 = 3200 / 100 = 32
Answer: 105 square feet
Step-by-step explanation: The answer is 105 square feet because find the area of the pool by multiplying 12 and 20 to get 240. You then want to find the area of the total space. Add 3 to 12 and add 3 to 20. Then multiply 23 by 15 to get 345. You then want to subtract 345 - 240 to get rid of the extra space to get your answer of 105.
Exterior Angles Theorem is used.
The exterior angle of a triangle is equal to the 2 opposite interior angles.
Therefore, 65+78=143°, since 65 and 78 are the 2 opposite interior angles.
So, the answer is 143°
