Answer:
14 boys paid for the full year fee and 4 boys paid for the partial year fee
Step-by-step explanation:
Create a system of equations, where x is the number that paid for the $24 fee and y is the number that paid for the $16 fee:
24x + 16y = 400
x = y + 10
Solve by substitution by plugging in y + 10 as x:
24x + 16y = 400
24(y + 10) + 16y = 400
Solve for y:
24y + 240 + 16y = 400
40y + 240 = 400
40y = 160
y = 4
Then, plug in 4 as y to find x:
x = y + 10
x = 4 + 10
x = 14
So, 14 boys paid for the full year fee and 4 boys paid for the partial year fee.

The equation of line in point-slope form of the line that passes through the point (−1, −3) and has a slope of 4 is:
y+3=4(x+1)
Step-by-step explanation:
Given
m=4
and
Point = (x1,y1) = (-1,-3)
The general form of point-slope equation of line is:

Hence,

visited museum didn't visit museum Total
visited zoo 9 14 23
didn't visit zoo 5 2 7
Total 14 16 30
Simply look at the table and check the number that corresponds to visitors who visited the museum but did not visit the zoo. The number is 5.
Divide it by the total number of people surveyed. Total is 30.
Probability visited the museum but did not visit the zoo = 5/30 = 0.16666 or 16.67%</span>
