Given that z is a standard normal random variable, find z for each situation (to 2 decimals). the area to the left of z is .2119.

Given that z is a standard normal random variable,

the area to the left of z is .2119.

The area to the left of z is given and we need to find out the z-score

To find z we use z-score table

z- score table is attached below.

We look at the z- score that has value 0.2119

From the table we can see that 0.2119 has z-score -0.80

the area to the left of -0.80 is .2119.

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
