Step-by-step explanation:
The formula of volume is 4/3 × π × radius3.
volume of smaller sphere = 4/3 x 3.14 x 3*3*3
v = 113.04
volume of larger sphere = 4/3 x 3.14 x 6*6*6
v = 904.32
904.32 / 113.04 = 8
Answer:
The answer is 20x + 45
Step-by-step explanation:
SO distribute 5 into 4x and 9 to get 20x + 45
Answer: 0.345
Step-by-step explanation:
Given : The incomes of families in Newport Harbor are normally distributed with Mean : and Standard deviation :
Samples size : n=4
Let x be the random variable that represents the incomes of families in Newport Harbor.
The z-statistic :-
For x= $800,000
By using the standard normal distribution table , we have
The probability that the average income of these 4 families exceeds $800,000 :-
Hence, the probability that the average income of these 4 families exceeds $800,000 =0.345
