Answer:
Step-by-step explanation:
1,2,3,(4),5,6,7
median (middle number) or Q2 = 4
Q1 (lower quartile) = 2
Q3 (upper quartile) = 6
IQR = Q3 - Q1 = 6 - 2 = 4
So the general form followed most of the time is y=mx+b. The m represents the slope, so in this case the slope is 5.
Answer:
The slope is 2
Step-by-step explanation:
To find the slope, you can use two pair of coordinates to use the equation
m=
, so you can use the coordinates (1,2) and (2,4) and substitute the appropriate values into the equation, which would look like:
, which would simplify to
, which is 2, meaning that the slope is 2
Answer:
The width is 10 inches.
x(x + 3) = 70
x² + 3x = 70
Subtract 70 from both sides.
x² + 3x - 70 = 0
Factor the trinomial
(x - 7)(x + 10) = 0
Set each equal to zero.
x = - 7, - 10
Distance can't be negative so x = 7 is the right one. Now we plug in for the length (x + 3)
x + 3
7 + 3
10
Step-by-step explanation:
2.1 x 10 to the power of 4.
10x10= 100 x 10= 1,000 x 10= 10,000
10,000 x 2.1= 21,000
