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%
Answer
the picturre ?????
Step-by-step explanation:
It would take them another 2.5 hours. To solve this you first need to multiply 60 by 4 to get 240. Subtract 240 from 780 to get 540. Then, Multiply 65 by 6 to get 390. Subtract 390 from the remaining 540 to get 150. Divide the final 150 by 60 to get 2.5. this is the remaining time they have to go before they reach their family and friends.
Answer:
The density of salt solution is 
.
Step-by-step explanation:
Given that,
Volume of certain solution, V = 7.5 litres
Mass of salt in solution, m = 37 grams
We know that, 
We need to find the density of salt in the solution. The density of salt is given by mass per unit volume. The formula can be written as:
So, the density of salt solution is .
