Suppose a normal distribution has a mean of 266 and a standard deviation of 12. what is p(x ≥ 242)?

apex pls

Step-by-step explanation:

The formula for normal distribution is expressed as

z = (x - u)/s

Where

u = mean

s = standard deviation

From the information given,

u = 266

s = 12

x = 242

We want to determine P(x ≥ 242). This is the probability of x greater than or equal to 242

P(x ≥ 242) = 1 - P(x </=242)

For x = 242,

z = (242 - 266)/12 = -24/12 = -2

Looking at the normal distribution table, the corresponding z score for P(x </= - 2) is 0.02275

P(x ≥ 242) = 1 - 0.02275 = 0.97725

step-by-step explanation:

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
