As a company manager for the Quick Money Business there is a 0.40 probability that you will be promoted this year. There is a 0.72 probability that you will get a promotion or a raise. The probability of getting a promotion and a raise is 0.25. If you get a promotion, what is the probability that you will get a raise?

Answers

Answer 1

Answer:

Answer:

Probability of getting raise when you get promoted = 0.625

Step-by-step explanation:

We have to find the probability of getting a raise. So,

Promotion = P, Raise = R

First we find if you get the promotion, what is the probability that you will also get a raise

$P(R | P) = (P(P \& R))/(P(P)) = \frac {0.25}{0.4} = 0.625$

Probability of getting raise when you get promoted = 0.625.

Now we find the probability of getting a raise,

$P(P\ or\ R) = P(P) + P(R) - P(P \& R)\n\0.72 = 0.4 + P(R) - 0.25\nP(R) = 0.72 - 0.4 +0.25\nP(R) = 0.57$

So, the probability of getting raise = 0.57.

for his birthday torin got $50.00 more from his grandparents than from his uncle. his uncle gave him $10.00 less than his cousin torin recieved $135.00 in total how much did he recieve from his cousin

Answers

Let us assume that the amount Torin got from his grandparents = x
The amount Torin received from his cousin = y
Let us assume that the amount Torin got from his uncle = z
Now let us concentrate on the information's provided in the question.
Now
x = 50 + z
z = x - 50
z = y - 10
y = z + 10
We also know that
x + y + z = 135
Now if we replace the value of x and y that we have already got then
x + y + z = 135
50 + z +z + 10 + z = 135
3z + 60 = 135
3z = 135 - 60
3z = 75
z = 75/3
= 25
So the amount received from his cousin is $25

Adam builds model rockets. Where he lives , his backyard is 12 feet below sea level. When he ignites his rocket, it flies a maximum of 350 feet straight up into the air before releasing its parachute. What is the altitude of adams rocket at its highest point, as measured from sea level?

Answers

Answer:

The answer is 338 feet.

Step-by-step explanation:

Adam builds model rockets. Where he lives , his backyard is 12 feet below sea level.

The rocket flies a maximum of 350 feet straight up into the air before releasing its parachute.

So, the altitude of Adams rocket at its highest point, as measured from sea level = $350-12=338$ feet

350 _ 12= 338 ft above sea level.

This above is part B. I need help with filling in the blank. Will give 15 points for help. Please help it's for plato. And I'm add an attachment for Part A and the work I have for part A.

Answers

Answer:

Part A y = 15(1 + 0.4)^x.

Part B 434 after 10 days.

Step-by-step explanation:

Part A.

21 = 15 ( 1 + r)^1

15 + 15r = 21

15r = 6

r = 6/15 = 0.4

So the equation is

y = 15(1 + 0.4)^x.

Part B.

So after 10 days x = 10

y = 15(1 + 0.4)^10

y = 434 to the nearest whole number.

Answer:

y = 434 to the nearest whole number.

Step-by-step explanation:

A businessman has 10 employees. His salary is equal to 6 times the average of employees salaries. If the 11 of them receive a total of $64,000 in one year, what was the business mans salary that year ?? a) $4000, b) $6000, c) $24,000, d) $ 40,000, e) $44,000

Answers

business man's salary = x
employee's salary = y

x + 10y = 64000
x = 6y

(6y) + 10y = 64000
16y = 64000
y = 4000

x = 6(4000)
x = 24000

Answer: (c) $24,000
