Answer:
The number of children = x = 176
The number of Adults = y = 87
Step-by-step explanation:
Let us represent
The number of children = x
The number of Adults = y
On a certain hot summer's day, 263 people used the public swimming pool.
x + y = 263.... Equation 1
x = 263 - y
The daily prices are $1.25 for children and $2.50 for adults. The receipts for admission totaled $437.50.
$1.25 × x + $2.50 × y = $437.50
1.25x + 2.50y = 437.50.....Equation 2
We substitute 263 - y for x in Equation 2
1.25(263 - y) + 2.50y = 437.50
328.75 - 1.25y + 2.50y = 437.50
- 1.25y + 2.50y = 437.50 - 328.75
1.25y = 108.75
y = 108.75 ÷ 1.25
y = 87
Solving for x
x = 263 - y
x = 263 - 87
x = 176
Therefore:
The number of children = x = 176
The number of Adults = y = 87
Answer:
765
Step-by-step explanation:

The stem-and-leaf plot for the distribution is given as follows:
- 3| 0 1 1 2 3 3 4 5 5 5 7 8 9
b) From the plot, the correct options are given as follows:
- A typical content is 32 calories per 100 ml.
- The distribution is roughly symmetric.
<h3>What is a stem-and-leaf plot?</h3>
The stem-and-leaf plot lists all the measures in a data-set, with the first number as the key, for example:
4|5 = 45.
For this problem, the observations are given at the top in red, and using each <u>first digit as the key</u>, the stem and leaf plot is:
- 3| 0 1 1 2 3 3 4 5 5 5 7 8 9
The mean of these observations is:
(19 + 2 x 22 + 23 + 25 + 2 x 27 + 2 x 28 + 30 + 2 x 31 + 32 + 2 x 33 + 34 + 3 x 35 + 37 + 38 + 39 + 2 x 40 + 41 + 43)/26 = 32(approximately)
The correct statements from the plot are as follows:
- A typical content is 32 calories per 100 ml(due to the mean).
- The distribution is roughly symmetric(13 values below the mean, 13 at or above).
