asambeis [7]

Answer:

The grade point average of the student is 49.92.

Step-by-step explanation:

A student earned grades :​ C, A,​ B, and A

Corresponding numbers of credit​ hours : 44​, 66​, 11​, and 66

Assigns quality points to letter grades :

A = 4 , B = 3 , C = 2 , D = 1 , F = 0

The grade point average​ (GPA):

\frac{\sum (\text{grade point}\times \text{credit hours})}{\sum (\text{grade point})}

=\frac{2\times 44+4\times 66+3\times 11+4\times 66}{2+4+3+4}

=\frac{649}{13}=49.9230\approx 49.92

The grade point average of the student is 49.92.

There are 30 boys in a sporting club. 20 of them play hockey and 15 play volleyball. Each boys plays at least one of the two gam
SVETLANKA909090 [29]

Answer:

<em>5 boys play all the two games</em>

<em>25 boys play only one game</em>

Step-by-step explanation:

<u>Sets</u>

There are two sets defined in the question: one for the boys who play hockey (H) and the other for the boys who play volleyball (V).

All the boys play at least one of the two games, so no elements are outside both sets.

There are 30 boys in total. 20 of them play hockey and 15 play volleyball. Since the sum of both numbers is greater than the total of boys, the difference corresponds to the boys who play both games.

Thus 20 + 15 - 30 = 5 boys play both games

Given that 5 boys are shared by both sets, from the 20 playing hockey, 15 play ONLY hockey. From the 15 boys playing volleyball, 10 play ONLY volleyball.

Thus 15 + 10 = 25 boys play only one game.

The Venn diagram is shown in the image.

Need help step by step​

Y = mx + b

8x - 4y - 9 = 0

first you move the nine to the other side of the equal sign (add nine to both sides)

8x - 4y = 9

then you need to also move your 8x over to the other side as well (remember we are trying to get y by itself!)

- 4y = -8x + 9

then we are going to divide -4 to both sides

and you get

y = 2x - 9/4

we can then identify the slope as 2

so B. 2 would be your answer

hope this helped
