$2 {y}^{2} - 9y - 2 + 4(y + 1) =$

$2 {y}^{2} - 9y - 2 + 4y + 4 =$

$2 {y}^{2} - 9y + 4y - 2 + 4 =$

Collect like terms

$2 {y}^{2} - 5y + 2 =$

$(2y - 1 )(y - 2)$

What is the probability that Geraldo, the 25-year-old you’re considering for a 30-year policy, lives to be 55 years old? Remembe

gogolik [260]

Answer: 1

Step-by-step explanation:

Given:

Geraldo current age = 25years.

Policy being considered for = 30years

Age at the end of the policy = 55years

What is the probability that Geraldo lives to be 55years.

Therefore

P ( A + B ) = 25 /55 + 30 / 55

= 5 / 11 + 6 / 11

= 11 / 11

= 1

56% enrolled if a same of 500 is randomly selected what probability 250 will get selected?

dalvyx [7]

I'll get you started:

mean = np = (500)(.56) = ?

standard deviation = √npq = √(500)(.56)(.44) = ?

Note: q = 1 - p

Finish the calculations.

To find z-score:

z = (x - mean)/sd

Note: x = 250

Once you have the z-score, look in a z-table using the score to find your probability. Remember that the question is asking "at least 250" when looking at the table.
