Answer:
a. 74.63%
b. 33.63%
c. 87.67%
Step-by-step explanation:
If 59% (0.59) of the workers are married, then It means (100-59 = 41%) of the workers are not married.
If 43% (0.43) of the workers are College graduates, then it means (100-43= 57%) of the workers are not college graduates.
If 1/3 of college graduates are married, it means portion of graduate that are married = 1/3 * 43% = 1/3 * 0.43 = 0.1433.
For question a, Probability that the worker is neither married nor a college graduate becomes:
= (probability of not married) + (probability of not a graduate) - (probability of not married * not a graduate)
= 0.41 + 0.57 - (0.41*0.57) = 0.98 - 0.2337
= 0.7463 = 74.63%
For question b, probability that the worker is married but not a college graduate becomes:
=(probability of married) * (probability of not a graduate.)
= 0.59 * 0.57
= 0.3363 = 33.63%
For question c, probability that the worker is either married or a college graduate becomes:
=probability of marriage + probability of graduate - (probability of married and graduate)
= 0.59 + 0.43 - (0.1433)
= 0.8767. = 87.67%
13/99 can't be simplified any further, because 13 is a prime number, meaning that 13 has only 2 factors 1 and itself.
An easy way to do this question is finding 40% of 120 then subtracting it from $120. This is done in a few ways, i use the unitary method:
120/100= 1% =1.2
x40 to find 40% = $48
120-48= 72
The sale price is 72
OR
multiply 120 by .6 to find the result with 40% taken away
Answer:
66m*2
Step-by-step explanation:
2(20m + 13m)
= 66m*2
9 and then put a pi symbol. You do 3squared since it’s the radius and that’s 9. Then since it’s wanted in terms of pi that’s it. 9pi
