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.

Karina is showing her steps to solve the expression −26.7 ÷ 1/3

timama [110]

Step 2: -26.7 · -3

When you divide with a fraction, it's helpful to multiple by the reciprocal of the fraction .

This step instead multiplied by the negative reciprocal .

Therefore, the correct answer would be -80.1 instead of 80.1

The error was made in step 2.

Enter an equation in point-slope form for the line. (6,8) and (7,1) is on the line. The equation of the line in point slope form

Yuri [45]

Answer:

$y - 8 = -7(x - 6)$ or $y - 1 = -7(x - 7)$

Step-by-step explanation:

The point-slope form equation is $y - b = m(x - a)$ , where,

(a, b) = a point on the line.

$m = slope = \frac{y_2 - y_1}{x_2 - x_1}$

Given the two points, (6, 8) and (7, 1), find the slope of the line:

$m = \frac{1 - 8}{7 - 6}$

$m = \frac{-7}{1}$

$m = -7$

There are two possible point-slope equation we can come up with using each points on the line given.

Using the point (6, 8) and m = -7,

Substitute m = -7, a = 6, and b = 8 into $y - b = m(x - a)$

$y - 8 = -7(x - 6)$

Using the point (7, 1) and m = -7,

Substitute m = -7, a = 7, and b = 1 into $y - b = m(x - a)$

$y - 1 = -7(x - 7)$
