If the number of equally likely sample outcomes of a single stage of an experiment is 4, what is the total number of elements in the sample space if the experiment has 3 stages? a. 16 b. 12 c. 64 d.

C. 64

Step-by-step explanation:

We know that the number of total elements in the sample space is given by :_

, where N is the number of total possible outcomes for an event and n is the number of times event is repeated.

Given: The number of equally likely sample outcomes of a single stage of an experiment = 4

The number of stages in the experiment = 3

Then , the total number of elements in the sample space :-

Hence, the total number of elements in the sample space = 64.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

it would open into a square depending on the type of envelope i’m not sure about the second part
