ipn [44]

Answer:

Prob = 95.0%

Explanation:

There are 382 people in total

69 respond and are in the 18-21 age bracket

12 refuse to respond and are in the 18-21 age bracket

282 respond and are in the 22-29 age bracket

19 refuse to respond and are in the 22-29 age bracket

Then, the number of people that are in the 18-21 age bracket or agreed to respond is

69 + 12 + 282 = 363

Therefore, the probability of getting someone in the 18-21 age bracket or someone who agreed to respond is

P = 363/382

P = 0.9502

P = 95.0 %

Multiply 2 y (one-fourth y + three-fourths). 9 over 4 y + 11 over 4 one-half y + 6 over 4 one-half y squared + 6 over 4 y 9 over
Illusion [34]

The result of multiplying 2y (one-fourth y + three-fourths) is one-half y squared + 6 over 4 y

<h3>Multiplication of numbers</h3>

  • 2 y (one-fourth y + three-fourths).

2y(1/4y + 3/4)

= (2y × 1/4y) + (2y × 3/4)

= 2/4y² + 6/4y

= 1/2y² + 3/2y

Given options:

  • 9 over 4 y + 11 over 4

= 9/4y + 11/4

  • one-half y + 6 over 4

= 1/2y + 6/4

  • one-half y squared + 6 over 4 y

= 1/2y² + 6/4y

  • 9 over 4 y squared + 11 over 4 y

9/4y² + 11/4y

Therefore, the result of multiplying 2y (one-fourth y + three-fourths) is one-half y squared + 6 over 4 y
