Answer:The answer is and the number in green box =7
Step-by-step explanation:
P(Sophomore| Girl)=?
We have P(A | B) =P(A∩B)/ P(B)
P(Sophomore∩Girls)=
Total Students =8+12+5+5 =30
Total girls =4+7+3+4 =18
P(Girls)=
P(Sophomore | Girl)=P(Sophomore | Girls)/P(Girls)
=
=
The number in green box =7
Let be "x" the number of hours of your work week you spend stocking shelves.
According to the information provided in the exercise, you work a total of 20 hours each week and you spend 3/5 of that time stocking shelves.
You can write that fraction as a decimal number by dividing the numerator by de denominator:
Then, to find the value of "x", you only need to multiply the total hours you work each week by 0.6.
Therefore, the result is:
You spend 12 hours of your work week stocking shelves.
