Answer:
A cookie costs $4/7
Step-by-step explanation:
Let's write an eqution in which X represents the cost of a cookie
14x=8

Now simplify by 2
[tex]x=\frac{4}{7}[/tex]
So a cookie costs $4/7

Find the scale factor for the dilation shown.
Answers
First you need to find the length and height of the squares.
Bigger square:
Length = 20
Height = 16
Small square:
Length = 5
Height = 4
Then take the heights and lengths and divide the bigger numbers (lengths in this case) by the smaller numbers (heights in this case)
*This is using inverse operations. Diving to get what to multiply, since scale factor is multiplying.
bigger shape LENGTH divided by smaller shape LENGTH:
20 units / 5 units = 4
bigger shape HEIGHT divided by smaller shape HEIGHT:
16 units / 4 units = 4
There’s your answer!
Also you didn’t really have to do lengths AND heights, only one, because you already knew both shapes were similar.
if you didn’t know:
the “/ “ symbol means divide

Answer: C. The housecats' weights have a higher mean and are more consistently centered around their mean.
Step-by-step explanation:
if we were being more technical then he would be correct because the house cats have a higher mean than the smaller dogs.
SD= 9.9
HC= 11
so the house cats have a higher mean than the smaller cats, in addition has a more consistent mean then smaller dogs due to the range of the lowest in the highest number.

C. The housecats' weights have a higher mean and are more consistently centered around their mean.
