Answer:
it's 2.06
Step-by-step explanation:
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:
29 years
Step-by-step explanation:
In 29 years the grandson will be 40 and the grandfather will be 80. 80 is twice as much as 40.
Answer:
HJ
Step-by-step explanation:
we know that
If two lines are parallel, then their slopes are the same
so
The slope of the line that is parallel to a line that has a slope of 3 is equal to 3
Verify the slope of the blue and red line , because their slopes are positive
<em>Blue line</em>
we have
C(-3,0),D(3,2)
The slope m is equal to
m=(2-0)/(3+3)
m=2/6
m=1/3
<em>Red line</em>
we have
H(-1,-4),J(1,2)
The slope m is equal to
m=(2+4)/(1+1)
m=6/2
m=3
therefore
The answer is the red line HJ
2x^2+9x+9
2x^2+6x+3×+9
2x(x+3)+3(x+3)
(2x+3)(x+3)
