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.
Answer:
It would be (3,2) since it is being reflected over the line it is already on

This question may be trick question xD haha.
Anyways, a right triangle is a triangle with a right angle (90 degrees). In your picture, that triangle is a right triangle, but the sides could be a bit slanted. Please take a picture from top view, so I can see it properly.
The triangle's length does not matter in this case. As long as it has a right angle, it's a right triangle.
Answer:
answer: 5x + 10
Step-by-step explanation:
The distributive property (of which this is an example) demands that the 5 must multiply the x (which was done correctly) to give 5x
But the problem becomes undone when you forget about the 2. You must multiply the 2 by 5 as well to give 10.
The plus sign cannot be destroyed. The terms are not alike. So the answer is 5x + 10
