Answer 1

Answer:

Answer: (a) 0.87x

(b) 0.87x = 174

(c) 200 players

Step-by-step explanation:

$\n$ Let x be the total number of players who signed up for the season,

$\n$ since 13% dropped , it implies that 13% of x dropped out , which means 0.13x dropped out.

$\n$ To know the players who finished the league , it implies

$\n$ x - 0.13x = 0.87x

$\n$ This means that 0.87x finished the league

$\n$ (a) The expression for the number of players who finished the season will therefore be 0.87x , this is as a result of subtracting those that dropped out (0.13x) from those that signed up ( x)

$\n$ (b) The equation to represent the number of players who signed up for the soccer will thus be:

$\n$ $\n$ x - 0.13x = 174 , since it was given that 174 finished the league, this implies

$\n$ 0.87x = 174

$\n$ (c) Solving the equation, we have

$\n$ 0.87x = 174

$\n$ 0,87x / 0.87 = 174 / 0.87

$\n$ x = 200

$\n$ Therefore 200 players signed up for the league

Answer 2

Answer:

Step-by-step explanation:

a. 87% finished the season because 13% dropped

b. 100×174 = 87x

c. 17400 = 87x ➡ x = 17400 ÷ 87 ➡ x = 200 player signed up for the soccer league.

What is the mean of 72,73,86,59,75,58,50,55

Answers

MEAN

Mean is the average. To find the mean of a data set, you have to add all the numbers and divide the sum by the amount of numbers you added.

In this equation, you have 8 numbers. That means you will be dividing by 8.

The first thing you need to do is add all the numbers. Add:

$72+73+86+59+75+58+50+55 = \bf 528$

Now that you have added all the numbers and got the sum, divide by 8. Remember that you will be dividing by 8 since you added 8 numbers.

Divide:

$528 / 8 = \bf 66$

The mean is 66

If you have any questions, feel free to ask in the comments! :)

The answer is 66.

Step by step explanation:
First, add all of the numbers together.
Then, divide the sum of the numbers by the number of entries you see.

Since there’s 8 numbers, you divide it by 8.
