A - actually not true, a probability plot would be better
B - not true, since exact values are plotted a box-and-whisker would be better
C - true (that's what a histogram does)
D - True (You can get the measures of central tendency quickly)

2:
A - true
B - False - those are easily found
C - False - They are arranged on the x-axis

Suppose a parabola has an axis of symmetry at x = -8 , a maximum height of 2, and passes through the point (-7, -1). Write the e
lidiya [134]
As it has a maximum value the coefficient of x^2 will be negative

The vertex will be at (-8,2)  so in vertex form it is

y = a(x + 8)^2 + 2
and as it passes through (-7,-1) we have:

-1  = a(-7+8)^2 + 2

-1 = a + 2  so a = -3

answer is  y = -3(x + 8)^2 + 2

in standard form this is y = -3x^2 -48x  - 190

Solve for y. <br><br> xy + p = 5<br><br> A) y = 5 - p - x<br> B) y = (5-p)/x<br> C) y = 5 - px
Damm [24]
Minus p both sides
xy=5-p
divide both sides by x
y=(5-p)/x

Find the slope of the line 8x – 4y = 8\ (hint: find 2 points; then use the slope formula)
Vera_Pavlovna [14]
8x - 4y = 8

-4y = -8x + 8

y = -8x/-4 + 8/-4

y = 2x - 2,  comparing to y = mx + c, slope m = 2

Slope = 2.
