Answer:

(x + 1)(x + 8)

Step-by-step explanation:

You can try expanding each of these expressions to check if they equal

x^2 + 9x + 8

or you can use the Diamond Method to factor this trinomial.

1*8 = 8 and 1 + 8 = 9

x^2 + x + 8x + 8 = x^2 + 9x + 8

x(x + 1) + 8(x + 1) = x^2 + 9x + 8

(x + 8)(x + 1) = x^2 + 9x + 8

Major league baseball salaries averaged $1.5 million with a standard deviation of $0.8 million in 1994. suppose a sample of 100

seropon [69]

Answer: The probability that the avg. salary of the 100 players exceeded $1 million is approximately 1.

Explanation:

Step 1: Estimate the standard error. Standard error can be calcualted by dividing the standard deviation by the square root of the sample size:

$SE=\frac{0.8}{\sqrt{100}}=\frac{0.8}{10} = 0.08$

So, Standard Error is 0.08 million or $80,000.

Step 2: Next, estimate the mean is how many standard errors below the population mean $1 million.

$\frac{1 - 1.5}{0.08}$

$=-6.250$

-6.250 means that $1 million is siz standard errors away from the mean. Since, the value is too far from the bell-shaped normal distribution curve that nearly 100% of the values are greater than it.

Therefore, we can say that because 100% values are greater than it, probability that the avg. salary of the 100 players exceeded $1 million is approximately 1.
