Sara spent half of her allowance going to the movies. She washed the family car and earned 9 dollars. What is her weekly allowance if she ended with 16 dollars ?

Answer:

Option C - (Maria , Jack and Bo)

Step-by-step explanation:

Given : The Venn diagram shows the pizza topping preferences for 9 students.

To find : What are the elements are in A and B?

Solution :

Let event A =  student like pepperoni

Let event B = students like olives  

We have to find the elements in A and B

A and B means the intersection of event A and event B.  

From the Venn Diagram, the number of students who likes Pepperoni and Olives are the students in the intersection of the two circles inside the rectangle.

The students in the intersection of A and B are Maria , Jack and Bo.

Therefore, Option C is correct.

Answer:A can be use to form a triangle.

Step-by-step explanation:

a+b>C

5+18 >20

23>20

SO this is a triangle since if you add A and B together it is greater than C.

Answer: y = 1/2x + 4

Final answer:

The average change in field position per run is -2 1/4 yards. This is found by dividing the total yardage lost (6 3/4 yards) by the number of runs (3).

Explanation:

The subject of this problem is calculating the average. In this case, we are looking for the average yardage lost by the running back on each run. The running back for the Bulldogs football team has carried the ball 3 times for a total loss of 6 3/4 yards.

To find the average change in field position on each run, divide the total loss by the number of runs:

1. Convert the mixed number 6 3/4 to an improper fraction. This gives us 27/4.
2. Divide the numerator (27) by the denominator (4). This gives us -6.75.
3. Divide -6.75 by 3 (the number of runs). This gives us -2.25.
4. Convert -2.25 to a mixed number, which gives us -2 1/4.

Therefore, -2 1/4 yards is the average change in field position on each run.
