Answer:

A. False

C. False

B. False

D. True

Step-by-step explanation:

Frequency histogram is denote the actual frequency of each observation or different class- intervals whereas Relative frequency distribution shows the fraction of that frequency to the total frequencies or the percent of that frequency to the total.

Thus the shape of both histogram are same.

A. False.

C. False

Since, Scale of the y-axis is different. But they has same shape.

B. False

Since, vertical scale is different for both histogram and horizontal scale is same.

D. True

What are the 2 factors that multiply 15000 and adds up to 5

s2008m [1.1K]

Ok so there are no real solutions for xy=15000 and x+y=5
there are immaginary solutions though so

xy=15000
x+y=5

x+y=5
y=5-x

x(5-x)=15000
-x^2+5x=15000
0=x^2-5x+15000
quadriacic formula
if ax^2+bx+c=0, then
x= $\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}$

x^2-5x+15000
a=1
b=-5
c=15000
x= $\frac{-(-5)+/- \sqrt{(5)^{2}-4(1)(15000)} }{2(1)}$
x= $\frac{5+/- \sqrt{25-60000} }{2}$
x= $\frac{5+/- \sqrt{-59975} }{2}$
x= $\frac{5+/- 5i\sqrt{2399} }{2}$
so the numbers are
$\frac{5+ 5i\sqrt{2399} }{2}$ and $\frac{5- 5i\sqrt{2399} }{2}$
