Theo is using this spinner to predict the favorite movie genre of randomly chosen students in his school. if theo spins the spinner 60 times, how many times should he expect it to land on "action"?
a) 10
b) 12
c) 15
d) 20

Option B.

Step-by-step explanation:

In the question the number categories on the spinner are not given.

Consider there are 5 different categories on the spinner.

A = Spinner land on "Action".

So, probability of  land on "Action" is

Number of spins, n= 60 times

The expected number of land on "Action" is

Therefore, the correct option is B.

Step-by-step explanation:

If there are 6 genre on the spinner, that represents the total possible outcomes, and Action is only one of them, so its probability in one try is

Then, he tried 60 times, that means we have to multiply the simple probability to the total number of trials.

He should expect to land on Action 15 times out of 60.

Therefore, the right answer is c) 15.

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
