In 2014 the tenants at jefferson school’s fall festival was 650. in 2015 the attendance was 575. what was the percent change in attendance from 2014 to 2015

The percent change in attendance from 2014 to 2015 is 11.54 %

Solution:

Given that,

In 2014 the tenants at Jefferson school’s Fall festival Was 650

In 2015 the attendance was 575

To find: percent change in attendance from 2014 to 2015

Percentage change equals the change in value divided by the absolute value of the original value, multiplied by 100.

Change in attendance from 2014 to 2015 = attendance from 2014 - attendance from 2015

Change in attendance from 2014 to 2015 = 650 - 575 = 75

Therefore percentage change is given as:

Thus the percent change in attendance from 2014 to 2015 is 11.54 %

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
