Katie made desserts for a bake sale at her school. At the bake sale, she sold 5 brownies and 15 cookies. What percent of the desserts that Katie sold were cookies? Please help me .

Percent of cookies to total desserts = 75%

Step-by-step explanation:

Given:

Number of brownies sold by Katie = 5 brownies

Number of cookies sold by Katie = 15 cookies

Find:

Percent of cookies to total desserts

Computation:

Number of total desserts = 5 brownies + 15 cookies

Number of total desserts = 20 desserts

Percent of cookies to total desserts = [Number of cookies sold by Katie / Number of total desserts]100

Percent of cookies to total desserts = [15 / 20]100

Percent of cookies to total desserts = [0.75]100

Percent of cookies to total desserts = 75%

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
