Employees salary [$}: 30,000, 30,000, 35,000, 35,000, 40,000, 40,000.

CEO Salary: $70,000.

The correct answer is this: BOTH JAN AND MARCY ARE CORRECT.

Jan says the employee average salary is $35,000. This is correct as shown below:

Average employee salary = 30,000 + 30,000 + 35,000 +35,000 + 40,000 + 40,000 / 6 = 210 / 6 =  $35,000.

Marcy says the average salary of all company members is $40,000. This is also true as shown below.

Average salary of all company members = 30,000 + 30,000 +35,000 + 35,000 + 40,000 + 40,000 + 70,000 / 7 = 280 / 7 = $40,000.

What is an equation of the line that passes through
lys-0071 [83]

Answer:

B

Step-by-step explanation:

For the perpendicular of an equation you need to flip the fraction and change the sign from positive to negative or if it's negative to positive. 3/2 is changed to -2/3 which when multiplied by -2 gives you 4/3 and 4/3+5/3 is equal to 3.

y = 80x - 60

Answer is B. y = 80x - 60

Double check:

When x = 1, y = 80(1) - 20 = 80 -60 = 20

When x = 2, y = 80(2) - 20 = 160 -60 = 100

When x = 3, y = 80(3) - 20 = 240 -60 = 180

When x = 4, y = 80(4) - 20 = 320 -60 = 260

When x = 5, y = 80(5) - 20 = 400 -60 = 340

Use suitable identities to find the following products (x+4)(x+10)​
Anestetic [448]

Answer:

x^2 + 14x + 40

Step-by-step explanation:

Here we gonna use the identity -

(x+a)(x+b) = x^2+(a+b)x + ab

So  using the identity here,

(x+4)(x+10) \\=> x^2 +(4+10)x+4*10\\=>x^2+14x+40
