Answer:

z-score = 5

Step-by-step explanation:

the annual salaries of all employees at a financial company are normally distributed with a mean of $34,000 and a standard deviation of $4,000.

To find z-score we use formula

z= \frac{x- mean}{standard \ deviation}

annual salary of $54,000, x is 54000

Plug in the values in the formula

z= \frac{x- mean}{standard \ deviation}

z= \frac{54000- 34000}{4000}=5

Answer:

7.04*4=x

x/3=how much the tickets cost

Step-by-step explanation:

If each of the four friends pays $7.04, the equation would be set up like this: 7.04*4=28.16. This means the total cost for tickets is 28.16. If the total cost for three tickets is 28.16, just divide the total cost by how many tickets were purchased. 28.16/3=9.39. This means one ticket cost 9.39.

(9h+3)(−h−1) porfavor ayudenme con esta pregunta.
BartSMP [9]

Answer:

-9h² - 12h - 3

Step-by-step explanation:

Follow the FOIL method:

FOIL = First, Outside, Inside, Last

Multiply the terms together:

First: 9h * -h = -9h²

Outside: 9h * -1 = -9h

Inside: 3 * -h = -3h

Last: 3 * -1 = -3

Combine like terms: 9h² + (-9h - 3h) - 3

9h² - 12h - 3

-9h² - 12h - 3 is your answer.
