There is a bag with only red marbles and blue marbles.
The probability of randomly choosing a blue marble is
5/12
.
There are 72 marbles in total in the bag and each is equally likely to be chosen.
Work out how many red marbles there must be.

Answers

Answer 1

Answer:

42 reds.

Step-by-step explanation:

There are 72 marbles in the bag.

P(Red) = 1 - Blue = 1 - 5/12 = 7/12

P(red) = 7/12 * 72 = 42

If 1 - 5/12 confuses you, then find the blue first

5/12 * 72 = 5 * 72/12 = 5 * 6 = 30

The rest must be red.

72 - 30 = 42

Step-by-step explanation:

To change triangle PQR to XYZ you divide by 4. This can be seen in the change from 12 to 3 on the left side of the triangle. So, you divide 20 by 4 and get 5 and then divide 16 by 4 and get 4.

12/4=3

20/4=5

16/4=4

So, you add these values together to get the perimeter of 12.

A graph titled Monthly Sales and Advertising Costs has Advertising Costs (1,000 dollars) on the x-axis and sales (1,000 dollars) on the y-axis. A line goes through points (6.4, 117) and (6.6, 120). The slope of the trend line is 15. What does that mean in regard to the data of the scatterplot? Check all that apply. The slope represents the rate of change of the data. Advertising costs increase $15,000 as sales increase by $1,000. Sales increase $15,000 as ads increase by $1,000. A positive slope infers a negative correlation. A positive slope infers a positive correlation.

Answers

The data in the scatterplot on monthly sales and advertising costs, show that:

The slope represents the rate of change of the data. Sales increase $15,000 as ads increase by $1,000.A positive slope infers a positive correlation.

What can be inferred from the graph on Monthly sales?

In a linear model, the slope is used to depict the change in the value of y as a result of a change in x. If this slope is positive, then there is a positive relationship between the y and x values.

In this scenario, the slope is positive which shows that there is a positive relationship between sales and advertisements such that they both increase together.

A
Liam can buy lunch for 7 or fewer people, including himself.

B
Liam can buy lunch for 7 or more people, including himself.

C
Liam can buy lunch for 6 or fewer people, including himself.

D
Liam can buy lunch for 6 or more people, including himself.

Answers

Answer:

C

Step-by-step explanation:

8 x 6 would equal 48, which results in not having enough money to buy lunch for more people.

Answer:

the answer should be c

Step-by-step explanation:

let's do a equation for this problem.

8x = 50

/8     /8

  x = 6.25

x represents the amount of friends. we divide 8 by both sides to isolate x by itself.

since the final result gives us a decimal, we have to round it to the nearest whole number. it's not possible to have a decimal amount of friends. it should be 6. it cannot be 7 if you are wondering because 7 is bigger than 6.25. there's no way there can be 7 friends when there is a limit amount of 6. therefore, the answer is c.

Sofia is a construction manager.She builds 9 house frames, each at a different site. Each frame uses 256 beams. A bundle of 400 beams delivered to each site. How many beams dose it take to build the 9 house frames? How many beams are left over at 9 house sites altogether

Answers

Answer:

2304 beams

1296 beams

Step-by-step explanation:

Total beams  to be used in the 9 houses = number of frames needed for a beam x total number of house frames

9 x 256 = 2304

Total beams left over = total number of beams delivered to the 9 houses - total number of beams  to be used in the 9 houses

total number of beams delivered to the 9 houses = 400 x 9 = 3600

3600 - 2304 = 1296

7:4 and 350:x

now,

350/7 = 50

and,

40 times 50 = 200

so, we have,

350:200

What will a $160,000 house cost 8 years from now if the price appreciation for homes over that period averages ​7% compounded​ annually?

Answers

Answer:

Step-by-step explanation:

We will use the A=P*(1+r/n)^nt formula

P = 160,000

R = the rate 7%

N= the times compounded. Since it is annually it is 1

T = 8 years

Filling in the information...

A = 160,000 x (1 + .07)^1*8

   = 160,000 x 1.07^8

   = 160,000 x 1.71818617983
