Given that z is a standard normal random variable, find z for each situation.
a. the area to the left of z is .9750
b. the area between 0 and z is .4750
c. the area to the left of z is .7291
d. the area to the right of z is .1314
e. the area to the left of z is .6700
f. the area to the right of z is .3300 (hint: normal probability dist)

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

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 .
