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)

step-by-step explanation: the answer for wha if rt is 10 centimeters long, and wha is st? it’s 6

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
