Answer:
%
Step-by-step explanation:
Probability is found by first forming a fraction where the numerator represents the number of desired outcomes and the denominator represents the total number of outcomes. In this case, the desired outcomes is the amount of times the coin lands on heads (9) and the total outcomes is the number of times the coin is tossed (20):

Divide numerator by denominator to get a decimal: 9÷20= 0.45
Multiply the decimal by 100 to get a percent: 0.45 x 100 = 45%
Answer:
The rate of return is 14%
Step-by-step explanation:
The rate of return can be determined by,
RR =
x 100%
where:
RR is the rate of return
is the final amount = $690 - $6 = $684
is the initial amount = $15 x 40 = $ 600
So that,
RR =
x 100%
= 0.14 x 100%
= 14%
Therefore, the rate of return is 14%.
Answer:
the C one is 18in and the E one is 12in
Step-by-step explanation:
If you subtract 1.1 from 5.8 you will end up with 4.7
then you subtract 10^7 from 10^8 which will give you 10^1
then you add the seven back which will give you your answer of
4.7 10^8
