The spinner is divided into equal parts. use a tree diagram to find the probability that the spinner will land on a vowel both times, if the spinner is spun twice. a. b. c. d.

Answer is

Step-by-step explanation:

Given is a spinner which is divided into equal parts of three.

One part has E, next part has U and third part has N.

Vowels are E, U comprising 2/3 of the area of the circle.

Tree diagram would be

I spin .... prob 2/3 ...landing on vowel .... ii spin ... prob 2/3 ... landing on a vowel

Hence required probability = product of two probabilities

=

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
