Answer:

n₁ = 8

n₂ = - 3

Step-by-step explanation:

√(7n + 25) - n = 1

√(7n + 25) = n + 1

[√(7n + 25)]² = (n + 1)²

7n + 25 = n² + 2n + 1

n² + 2n + 1 - 7n - 25 = 0

n² - 5n - 24 = 0

n² + 3n - 8n - 24 = 0

n(n + 3) - 8(n + 3) = 0

(n - 8)(n + 3) = 0

n - 8 = 0 => n₁ = 8

n + 3 = 0 => n₂ = - 3

Tina spent 3/5 of her paycheck on a trip to the beach. She spent 3/8 of her paycheck on new clothes for the trip. What fraction

yuradex [85]

Answer:

<u>Tina spent almost all her paycheck on the trip and buying new clothes for the trip. She spent 39/40 of her paycheck.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount spent by Tina on a trip to the beach = 3/5

Amount spent by Tina on new clothes = 3/8

2. What fraction of her paycheck did Tina spend on the trip and clothes together?

Total spent by Tina on the trip and new clothes = 3/5 + 3/8

Total spent by Tina on the trip and new clothes = 24/40 + 15/40 = 39/40

<u>Tina spent almost all her paycheck on the trip and buying new clothes for the trip. She spent 39/40 of her paycheck.</u>

Answer:

0.055 = 5.5% probability that exactly 5 employees were over 50.

Step-by-step explanation:

The employees are removed from the sample without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by the following formula:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

In which:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

7 + 18 = 25 employees, which means that $N = 25$

7 over 50, which means that $k = 7$

10 dismissed, which means that $n = 10$

What is the probability that exactly 5 employees were over 50?

This is P(X = 5). So

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

$P(X = 5) = h(5,25,10,7) = \frac{C_{7,5}*C_{18,5}}{C_{25,10}} = 0.055$

0.055 = 5.5% probability that exactly 5 employees were over 50.
