Lastima Nelson, Inc. is recruiting a new Chief Financial Officer (CFO). The recruiting budget is $44,000. Lastima has spent $10,
Musya8 [376]
The budget is $44000

Total spent so far is $10000 + $8500 = $18500

The amount left to spend = 44000 - 18500 = $25500

$25500 is the maximum 6% commission that Lastima Nelson Inc. can spend and stays within the budget

Let the maximum price of the home be x
This value of x will be the 100% before the 6% commission is calculated of it.

6% of x is 25500
1% of x is 25500 ÷ 6 = $4250
100% of x is 4250 × 100 = $425,000

So, the maximum value of the home is $425,000

Determine the equation
sergejj [24]

Answer:

y=\frac{3}{4} x-\frac{5}{4}

Step-by-step explanation:

two points on the line are

(-1, -2)

(-5, -5)

The slope:

m=\frac{-2-(-5)}{-1-(-5)} =\frac{-2+5}{-1+5} =\frac{3}{4}

The equation:

with (-1,-2)

y-(-2)=\frac{3}{4} (x-(-1))

y+2=\frac{3}{4} x+\frac{3}{4}

y=\frac{3}{4} x+\frac{3}{4} -\frac{8}{4}

y=\frac{3}{4} x-\frac{5}{4}

Hope this helps

A fair dice is rolled 3 times in a row. The outcomes are shown below.
maks197457 [2]

Answer:

1/3

Step-by-step explanation:

I think this is 1/3 because it is a ratio of successful outcomes to total number of outcomes..

Ex. Rolling a 6 sided dice.. you roll a 5...  it would be 1/6.

Hope that makes sense.
