Answer:
192x^4 - 192 x^3i
Step-by-step explanation:
a^3 b
Lets find a^3
a=4x
a^3
(4x)^3
64x^3
b = 3x-3i
a^3b
(64x^3) * (3x-3i)
Distribute
64x^3*3x - 64x^3 *3i
192x^4 - 192 x^3i
Answer:
10,000
Step-by-step explanation:
"The number who have been vaccinated against both is twice the number who have been vaccinated only against mumps."
Let b = number of children vaccinated against both.
Let m = number of children vaccinated only against mumps.
b = 2m
"If 5,000 have been vaccinated against both"
5000 = 2m
m = 2500
5000 children are vaccinated against both.
2500 children are vaccinated only against mumps.
The total number vaccinated against mumps is the number vaccinated only against mumps plus the number vaccinated against both:
2500 + 5000 = 7500
"the number of children who have been vaccinated against rubella is twice the number who have been vaccinated against mumps."
total number of children vaccinated against rubella = 2 * 7500 = 15,000
5000 of those children are vaccinated against both.
15,000 - 5000 = 10,000
10,000 children are vaccinated only against rubella.

Answer:
The 65th percentile is 37
Step-by-step explanation:
The 65th percentile is the number that splits the data in two groups. The amount of data that is less to the 65th percentile corresponds to the 65% of the data. Since we have 20 value, we calculate the 65% of 20, which is 13. By organazing the data from least to greatest, we count the values in the data set until we reach the 13th value, which in this case is 37.
