Answer:320 children and 262 adults swam in the public pool
Step-by-step explanation:
Let x represent the number of children that swam in the public pool.
Let y represent the number of adults that swam in the public pool.
582 people used the public swimming pool. This means that
x + y = 582
The daily prices are $1.50 for children and $2.00 for adults. The receipts for admission totaled to $1004.00. This means that
1.5x + 2y = 1004 - - - - - - - - - -1
Substituting x = 582 - y into equation 1, it becomes
1.5(582 - y) + 2y = 1004
873 - 1.5y + 2y = 1004
- 1.5y + 2y = 1004 - 873
0.5y = 131
y = 131/0.5 = 262
Substituting y = 262 into x = 582 - y, it becomes
x = 582 - 262 = 320
A and d................................
First factor out the gcf.
4x(x+4)
The inner binomial cannot be factored so that is the final answer.
Answer:
a.) 26< a <u>28 </u>
b.) 4
Step-by-step explanation:
a.) After looking at the age in years collum you can notice that all of ages have a difference of 2. With this you can infer that the missing number is 28.
b.) To find the mean add up all the numbers in the frequency column.
3+2+7+8+0=20
Divide that by the amount of numbers. There are 5 numbers so 20/5=4.
Hope this helps!
B 12 minutes
Because if you look the middle of the box plot the line is at 12
