You can use two method
First method: form a triangle from x = 4 to x = 7. See vertically and horizontally (count the squares). It would be 5 and 3. Therefore 5/3 would be the slope.
Second method: use the slope formula
Determine 2 points on the graph
(4,0) and (7,5)
Formula: (y2-y1)/(x2-x1)
(5-0)/(7-4) = 5/3
The slope is 5/3
ANSWER
The number of children between the ages of 9 and 15 who visited the park is
EXPLANATION
The number of children between the ages of 9 and 15 who visited the park are those within the age group 9 to 12 and 12 to 15.
We can from the graph that, the height of the bar that corresponds to the age group 9 to 12
and the height of the bar that corresponds to the age group 12 to 15
The sum of the two frequencies
Answer:
the answer is dams have changed
Step-by-step explanation:
2x+4=x+18
2x-x=18-4( Addition on the Right hand side changes to subtraction on the left hand side and wise-versa.)
1x=14
1x(1*x so X itself)
X=14
[((2 / 75.5) - 3) * 2]3 (make 3 an exponent.)
