Answer:
Step-by-step explanation:
InterQuartile Range is the difference in 3rd Quartile and 1st Quartile.
In box-plots, you can see two tails and a box. The left side of the box is the "first quartile" and the right edge of the box is "third quartile".
<u>For TOP BOX PLOT:</u>
3rd Quartile = 41
1st Quartile = 24
So, IQR (interquartile range) = 41 - 24 = 17
<u>For BOTTOM BOX PLOT:</u>
3rd Quartile = 35
1st Quartile = 28
IQR = 35 - 28 = 7
Difference in two IQRs is:
17 - 7 = 10
Correct answer is A
Answer:
a) parabola opens upwards
b) y-intercept y = 2
c) x₁ = 1 x₂ = 2
Step-by-step explanation:
y = x² - 3x + 2
This parabola is open upwards since the coefficient of x² is positive (1)
b) y-intercept is when x = 0 then
y = (0)² - 3*(0) + 2
y-intercept y = 2
to determine zeros, we can proceed as follows
x² - 3x + 2 = 0
Factoring that xpression
( x -1 ) * ( x - 2 ) = 0
Then either x- 1 = 0 and x₁ = 1 or
x - 2 = 0 and x₂ = 2
