Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm. If all the scoops are evenly distributed, they would all be 3.8 cm tall.
<h3>How to find the mean value of a data set?</h3>The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.
If the data set consists of values
x_1, x_2, ..., x_n
, then we get the mean value as:

Use this formula: 
a) d=11
Work:
d=sqrt((4-(-7))^2+(5-5)^2
d=sqrt((11)^2+(0)^2)
d=sqrt(121+0)
d=sqrt(121)
d=11
b) d=4
c) d = 16
d) d=160
e) d=12
a) d=11
Work:
d=sqrt((4-(-7))^2+(5-5)^2
d=sqrt((11)^2+(0)^2)
d=sqrt(121+0)
d=sqrt(121)
d=11
b) d=4
c) d = 16
d) d=160
e) d=12

Step-by-step explanation:
Given value:
They understand that, by using algebraic expressions laws, they subtract that inverse whenever we subtract powers with the same base. Every exponent's core is 2, therefore we subtract:
They have a shared denominator. It's least that is equally divided
among 8 or 2 is 8:
This gives us:
As rational notation is written as extremists, that root was its denominator as well as the power seems to be the numerator.
Which means 8 is the root and 5 the force that gives us:
