Find the area under the standard normal distribution curve for each.
yawa3891 [41]
From the standard normal tables, obtain
P(z<1.95) = 0.9744
P(z<0.37) = 0.6443
P(z<1.32) = 0.9066
P(z<1.82) = 0.9656
P(z<1.05) = 0.8531
P(z<2.05) = 0.9798
P(z<0.03) = 0.5120
P(z<0.53) = 0.7019

Answers:
    Range of z                                       Area
     --------------   ---------------------------------------
a.     0 - 1.95                                      0.9744
b.     0 - 0.37                                     0.6443
c.  1.32 - 1.82   0.9656 - 0.9066 =   0.0590
d. 1.05 - 2.05  0.9798 - 0.8531   =   0.1267
e. 0.03 - 0.53  0.7019 - 0.5120   =   0.1899

When using the quadratic formula we call the part under that radical the discriminant this part of the formula can be used to he
blondinia [14]

Answer:

A, B, and C

Step-by-step explanation:

The discriminant is denoted by b^2 - 4ac, and it can give us information about the roots of the quadratic equation.

It tells us that if:

- b^2 - 4ac < 0 , then there are 0 real solutions; they're all imaginary (involving the letter i, which is the square root of -1)

- b^2 - 4ac = 0 , then there is 1 real solution; this 1 solution has a multiplicity of 2 because the roots of the quadratic are the same number

- b^2 - 4ac > 0 , then there are 2 real solutions; there are no imaginary solutions

Looking at the possible choices, we see that all of A (A, I'm assuming you meant to write "if the discriminant is zero there is one real solution"), B, and C reflect the above properties.

Thus, they're all right.
