Answers

The formula for the area of a triangle is 1/2*b*h
The best thing to do is to multiply the answers then half them.
7*12= 84
84/2= 42
Therefore, the area is 42cm2

The probability distribution for a game is shown in the table below.what is the probability of NOT winning a cash prize if the game is played on time?

A) 7/10
B) 1/5
C) 4/5
D) 3/10

Answers

Given:

It is given that

Probability of winning $ 0 = (3)/(10)

Probability of winning $ 100 = (1)/(5)

Probability of winning $ 200 = (1)/(10)

Probability of winning $ 500 = (2)/(5)

To find the probability of not winning a cash prize.

Explanation:

Not winning cash prize = winning $ 0

So,

Probability of not winning a cash prize

= Probability of winning $ 0

= (3)/(10)

Therefore,

The probability of not winning a cash prize is (3)/(10). Option D.

What is the MAD of 15, 17, 15, 17, 21, 17, 15, 21, 20, and 18

Answers

Okay i will just do this step by step...

1st.) Find the mean of all the values. 
Of course finding the mean is adding all the numbers up together and dividing by the number of numbers present. 
So add all the numbers...
15 + 17 + 15 + 17 + 21 + 17 + 15 + 21 + 20 + 18 = 176
Now divide by 10 since there are ten numbers. 
176 
÷ 10 = 17.6 

2nd.) subtract the mean from each value, (ignore the minus signs in our answer, they are not needed, our answer will be a positive number!!!)
So...
15 - 17.6 = 2.6 
17 - 17.6 = 0.6
15 - 17.6 = 2.6 
17 - 17.6 = 0.6 
21 - 17.6 = 3.4
17 - 17.6 = 0.6 
15 - 17.6 = 2.6 
21 - 17.6 = 3.4
20 - 17.6 = 2.4
18 - 17.6 = 0.4 

Now our new Set of numbers is...
2.6, 0.6, 2.6, 0.6, 3.4, 0.6, 2.6, 3.4, 2.4, 0.4 

3rd.)  So now we have to take those numbers and find the Mean out of those... Soo first add them up together. 
2.6 + 0.6 + 2.6 + 0.6 + 3.4 + 0.6 + 2.6 + 3.4 + 2.4 + 0.4 = 19.2 
Now divide by the number of numbers present or in this case (10)
soooo
19.2 
÷ 10 = 1.92

sooooo
MAD = 1.92

Morgan and Leigh spend a certain amount of money from their money box each month to buy plants. The table shows the relationship between the amount of money (y) remaining in Morgan's money box and the number of months (x):

Function 1
Number of Months
(x) Amount Remaining (in dollars)
(y)
1 50
2 40
3 30
4 20


The equation shows the relationship between the amount of money (y) remaining in Leigh's money box and the number of months (x):

Function 2:
y = −9x + 60

Which statement explains which function shows a greater rate of change?
Function 1 shows a greater rate of change, because Morgan spends $10 each month and Leigh spends $9 each month.
Function 1 shows a greater rate of change, because Morgan spends $10 each month and Leigh spends $60 each month.
Function 2 shows a greater rate of change, because Morgan spends $10 each month and Leigh spends $60 each month.
Function 2 shows a greater rate of change, because Morgan spends $50 each month and Leigh spends −$9 each month.

Answers

the change for 1st function is -10 and rate of change of 2nd function is -9. Use the slope formula to find the  answer of 1st function.

Answer:

The first one since after each x interval the y is decreasing by 10 and in the second equation after each x interval the y is decreasing by 9

The first representation is the answer: Morgan
