Answer:
64.428
Step-by-step explanation:
well to find the mean we add all of the numbers up and then divide it by the amount of numbers in the sequence
so if we add all of the numbers up it will give us
451
then if we divide that by the number of numbers in the sequence which is 7 then that will leave us with
around 65 or exactly it would be
64.428
27 salads because if you out it in a proportion of 12/20=x/45 x= 27
the second question would be $7.40 because $29.60/4 is $7.40
You can set up proportions to find the width of the stream.
6/7.5=x/28
Cross multiply and solve for x.
168=7.5x
Divide by 7.5
x=22.4 ft
The stream is 22.4 ft wide
