Use a protractor to measure the degrees of the angles. Then, join them together.
Answer:
I will answer in a general way because the options are not given.
We know that the area of model A is smaller than the area of model B.
For model A, we have 72 shaded sections, out of 100.
Then the quotient of model A is:
72/100 = 0.72
For model B we have 10 sections, and x shaded ones.
Because model B is greater than model A, we know that:
x/10 should be larger than 72/100
then we have the inequality:
x/10 > 0.72
x > 0.72*10
x > 7.2
And we can not have more than 10 shaded sections (because there is a total of 10 sections) then:
10 ≥ x > 7.2
Then x can be any whole number in that interval.
the possible values of x are:
x = 8
x = 9
x = 10

-4/1 because y is going down by four and x is going down by 1.
Answer:
the median is 6 and the mean is 8.375
Step-by-step explanation:
first you have to arrange the numbers from least to greatest the median is the middle number which in this case there are two but both of them are 6 so the median is 6 and for the mean you just average by adding it all together then divide by the total
