use technology or a z-score table to answer the question.

the expression p(z < 1.87) represents the area under the standard normal curve below the given value of z.

what is p(z < 1.87)?

 d) 0.9693

Step-by-step explanation:

refer to the z-table attached.  

The table shows the percent from the MEAN.  The percent below the mean is 50% so that needs to be added to the value in the table.  

Look on the left side for 1.8 and the top for 0.07 (which is 1.87).  

The value is 0.4693 --> add 0.5 to that value to get 0.9693.

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
