Answer:
C
Step-by-step explanation:
First, eliminate choice B b/c the max is 28, not 26.
Next, lets find the median.
(12+18+20+20+24+26+28+28) = (20+24)/2 = 22
That leaves us with only A & C as a possible answer.
Q1 = The median of the first half of the data (12, 18, 20, 20)
Q1 = (18+20) / 2 = 19
A & C have the same Q1 values, so we need to compare Q3 values.
Q3 = The median of the second half of the data (24, 26, 28, 28)
Q3 = (26+28) / 2 = 27
The Correct Answer is C b/c A had a different Q3 value.
Answer:
8
Step-by-step explanation:
Answer:
Both Yes
Step-by-step explanation:
both have a 90 degree angle
Answer: 140
Oleg, Sasha, and Dima shared 600 toys. Sasha had twice as many toys as Oleg. Dima had 40 more toys than Oleg.
Let the number of toys Oleg has = x
Let the number of toys Sasha has = y
Let the number of toys Dima has = z
Sasha had twice as many toys as Oleg
So y = 2*x= 2x
Dima had 40 more toys than Oleg.
z = x + 40
Oleg, Sasha, and Dima shared 600 toys
x + y + z= 600
We know y=2x and z=x+40
Replace it for y and z
Subtract 40 on both sides
Divide by 4 on both sides
Oleg had 140 toys
