Answer:
79.5
Step-by-step explanation:
a^2 =b^2+ c^2-2bc cos A
cos p = 73^2+35^2-75^2/2(73)(35)
cos p= 9229/5110
cosp=79.5
Well, its increasing by 2262 so if we multiply that number by 2, it equals 4524.So the total would be 10,524. If I'm wrong, I'm sorry.
Decimal: .3, money: $30/$100
Decimal is .3 because 30/100 is like saying 3/10 or .3/1
Are you to combine the answer or are they 2 separate equations you need to solve for y?
Answer:
C. 5 weeks.
Step-by-step explanation:
In this question we have a random variable that is equal to the sum of two normal-distributed random variables.
If we have two random variables X and Y, both normally distributed, the sum will have this properties:

To calculate the expected weeks that the donation exceeds $120, first we can calculate the probability of S>120:

The expected weeks can be calculated as the product of the number of weeks in the year (52) and this probability:

The nearest answer is C. 5 weeks.
