Using the standard normal distribution, find the two z-scores that that form the middle shaded region. the shaded region is symmetric about z = 0 . round your z-scores to two decimal places.

Between (-0.675, 0.675)

Step-by-step explanation:

We know that a standard normal distribution curve is bell shaped unimodal , symmetrical about mean.

for thsi standard normal variate with notation z, we get mean =0 and std deviation = 1

For the middle shaded region, we find z such that the area between -z and z is 0.50 exactly half.

From standard normal distribution table, we get that z= ±0.675

Hence between z=-0.675 and z = 0.675 we get the middle region with area equal to exactly 1/2.

Between (-0.675, 0.675)

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
