Step-by-step explanation:
Find the MEAN with the information you have. Then say th edifference between the mean on the graph and the median.
Answer:
mean age of women
(x+y+z)/3=27
mean age of men
(x1+x2+x3+x4+x5+x6)/6=34
mean age of all people in the office
x+y+z=27*3=81
x1+...x6=34*6=204
so
mean age( x+y+z+x1+x2+..x6)/(3+6)=(27*3+34*6)/9
=(81+204)/9=285/9=32 approximately

After some algebraic manipulations, speeds are found:
Answer:
B. The total price depends on the number of crates
Step-by-step explanation:
We can immediately rule out C & A because the two factors in the graph are crates and total price. So both the number of crates and total price will be part of our answer, but pumpkins aren't shown on the graph at all.
This leaves us with B & D. Using common sense we know that the number of crates isn't going to change if the total cost changes but rather the total cost will change depending on how many crates you buy.
I hope that helps u understand & answers ur question! (If u have a question about anything I just said lmk and I'll be glad to tell u what I mean)
Good luck! :)
It might seem silly, but it's important to say that something is equal to itself. This applies to numbers like saying 2 = 2 and it also applies to geometric lengths as well. In line 5, we say that segment DB is the same length as segment DB. In short, DB is congruent to itself. This property is known as the reflexive property of congruence. You can think of a mirror giving off a reflection which has a similar word structure to reflexive.
You are correct if you were going to select choice B as the answer.
