find z-score for the standard normal distribution with mean 0 and standard deviation 1 with the probability 0.9850

z-score=2.17

Step-by-step explanation:

We are given that

Mean,

Standard deviation,

Probability, p-value=0.9850

We have to find z-score for the standard normal distribution  with mean 0 and standard deviation 1 with the probability 0.9850.

To find the z score for the standard normal distribution we will use z-table.

From z- table we get

p-value =0.9850 when z -score=2.17

z-score corresponding to p-value=2.17

Therefore, the z-score for the standard normal distribution with mean 0 and standard deviation 1 with the probability 0.9850=2.17

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
