Evan has equal numbers of pop songs, jazz songs, and rock songs loaded on his personal music player. He has it set to play songs

on a random shuffle. Suppose Evan is designing a simulation that could be used to estimate the probability that the next two songs to play are both jazz songs.
Which simulation design could Evan use to estimate the probability?

A. Coin
Let heads (H) = jazz
Let tails (T) = pop or rock
Toss coin three times. Repeat.

B. Number cube
Let 1 = pop
Let 2 jazz
Let 3 = rock
Roll cube four times. Repeat.

C. Number cube
Let 1,2 = pop
Let 3,4 = jazz
Let 5, 6 = rock
Roll cube two times. Repeat.

D. Random Digits
Let 1,2,3 = jazz
Let 4,5,6 = pop
Let 7,8,9,0 = rock
Select two random digits. Repeat.

arsen [322]

Answer:

X=2

Step-by-step explanation:

9x+1=2x+15

1. restar 1 de ambos lados  ejemplo: 9x+1-1=2x+15-1

2. simplificar Ejemplo: 9x=2x+14

3. restar 2x de ambos lados ejemplo: 9x-2x=2x-2x+14

4. simplificar ejemplo: 7x=14

5.divide ambos lados entre 7 ejemplo: 7x/7= 14/7

6.Simplificar ejemplo: x=2

The GCF 28a^3b and 16ab^2 <br><br> A)4ab<br> B)4a^3b<br> C)28ab<br> D)112a^3b^2
natulia [17]
The GCF of 28 and 16 is 4 since 28/4=7 and 16/4=4 and 7 and 4 are relatively prime. The gcd of a^3 and a is a. The gcd of b and b^2 is b. Thus, the gcd of the whole thing is 4ab so A is the answer.

The surface areas of two similar solids are 169 m2 and 81 m2. The volume of the larger solid is 124.92 m3. Which proportion corr
Tpy6a [65]

Answer: C

Step-by-step explanation:

Given 2 similar solids whose

ratio of sides = a : b, then

ratio of areas = a^2 : b^2 and

ratio of volumes = a^3 : b^3

Here the area ratio = 169 : 81, thus

side ratio = sqrt{169} : sqrt{81} = 13 : 9

Hence the volume ratio = 13^3 : 9^3

Using proportion then

frac{13^3}{9^3} = frac{124.92}{x} → C
