The plot for January places the median age at 40, so half of the surveyed group was over 40. That would be half of 100 people, or 50 people.
The plot for July places the upper quartile at age 40, so 1/4 of the surveyed group was over 40. That would be 1/4 of 100 people, or 25 people.
There were 50 - 25 = 25 more visitors over the age of 40 at the beach in January.
Answer:
x+y
Step-by-step explanation:
Let's pretend the value of the crayon's is 'y'. The value of the markers is 'x'. If we add them together, we get x+y. This is because we do not know the value of each variable.
Hope this helps! Have a nice day <3
Answer:
= 105(x+2)/33-x
Step-by-step explanation:
Given the expression
[3(x+2)*10*7]÷70 - 2(x+2)
= 3(x+2)*70÷70 - 2(x+2)
= 210(x+2)/70-2x-4
= 210(x+2)/66-2x
= 210(x+2)/2(33-x)
= 105(x+2)/33-x
Answer:
I believe the answer to the first question is:
R is the midpoint of PQ. (I think)
The answer to the second question is:
Rectangle. Because rectangles are the only shape in that list that has parallel sides and congruent angles.
And the answer to the third question is:
16, 16, 18. Because an isosceles triangle is a triangle that has two sides of the same length.
I hope this helps! :)
