​What's wrong with the following​ statement?
NeTakaya

Answer:

It is not a normal distribution but an uniform distribution

Step-by-step explanation:

A uniform distribution is one in which all values are equally likely within a range, therefore in lottery drawings, any of the numbers are likely to appear, however a normal distribution the values are likely to cluster around the mean, or average. Meaning that numbers far away from the mean won't appear that often, however, in lottery drawings, this normal distribution doesn't happen.

ipn [44]

The zeros are -5, 4

Step-by-step explanation:

x^2 +x - 20=0

What 2 number multiply to -20 and add to 1

5*-4 = -20

5+-4 = 1

Using the zero product property

x+5 = 0  x-4 =0

x=-5  x=4
