Answer:
85.7
Step-by-step explanation:
Given that two sections of a class took the same quiz. Section A had 15 students who had a mean score of 80, and Section B had 20 students who had a mean score of 90.
Section A total score = 15*80=1200
Section B total score 20*90 = 1800
Overall total score=3000
Overall total students = 15+20 =35
Hence overall mean =
rounding off to one decimal place
overall mean = 85.7
For these questions you’re distributing.
When multiplying exponents it’s quite simple
(x)(x)= x^2
(x^3)(x^3)= x^6
Raising a function with an exponent with another exponent
(x^4)^4 is x^16
So when two functions to a power are multiplied the exponents add. Then a function with an exponent is raised to another exponent, the exponents multiply.
b. 15h^2-10h
c. 12p^4-15pm
d. 12h^3+8h^2g
e. h^4+7h
Answer: $18.48
Step-by-step explanation: The formula for interest is I = PRT, where I equals interests, P equals the principle, R equals the rate and T is Time.
I = 308 x .06 x 1
I = $18.48
You will pay $18.48 interest for one year.
