Answer:

Just substitute..

y=3x for X

y=3(-1)

y=3(0)

y=3(1)

y=3(2)

y=3(3)

then what you get for y just plot it

what are the minimum first quartile median third quartile and the maximum of the data set? 9,20,4,18,4,18,20,9

Answers

Answers
1. Minimum = 4
2. First quartile = 6.5
3. Median = 13.5
4. Third quartile = 19
5. Maximum = 20

Explanation
To calculate the measure of central tendency, you first arrange the set of the data in ascending order.  
The set of data given will be;
4, 4, 9, 9, 18, 18, 20, 20.

Part 1:
The minimum value of the data is 4.

Part 2:
The first quatile is the median of the lower half which is comprised by:
4, 4, 9, 9

1st quartile = (4+9)÷2
                  = 13÷2
                  = 6.5

Part 3:
Median of the data is;

Median = (9+18)÷2
              =27÷2
            = 13.5

Part 4:
3rd quartile is the median of the upper half which comprises of; 
18, 18, 20, 20.

3rd quartile = (18+20)÷2
                  = 48÷2
                   = 19

Part 5
The maximum of the set of data is 20.

during a bike challenge, riders have to collect various colored ribbons. each 1/2 mile they collect a red ribbon, each 1/8 mile they collect a green ribbon, and each 1/4 mile they collect a blue ribbon. which colors of ribbons will be collected at the 3/4 mile marker?

Answers

The correct answer is:
green and blue.

Explanation:
We want to see which fractions (3)/(4) is a multiple of. We know that (3)/(4) is a multiple of (1)/(4), because (1)/(4)*3=(3)/(4).

We can divide fractions to determine if (3)/(4) is a multiple of (1)/(2):
( (3)/(4))/( (1)/(2));

in order to divide fractions, flip the second one and multiply:
(3)/(4))*(2)/(1)=(6)/(4)=1 (1)/(2).
This did not divide evenly, so (3)/(4) is not a multiple of 1/2.

Checking to see if (3)/(4) is a multiple of (1)/(8), ( (3)/(4))/( (1)/(8));

flip the second one and multiply:
(3)/(4)*(8)/(1)=(24)/(4)=6.
This divided evenly, so (3)/(4) is a multiple of (1)/(8).

Answer: Hello there!

As we know, each 1/2 mile there is a red ribbon, each 1/8 mile there is a green ribbon, and each 1/4 mile there is a blue ribbon.

We want to know which color of ribbons is in the 3/4 mile marker.

then we need to see if 3/4 is a multiple of some of the previous numbers.

Start with the red ribbons, we need to see the quotient between 3/4 and 1/2, if the result is a whole number, then 3/4 is a multiple of 1/2

this is q = (3/4)/(1/2) = (3/4)*2 = 6/4

here we haven't a whole number, then there is no red ribbon at the 3/4 mile marker.

now with the green ones:

(3/4)/(1/8) = (3/4)*8 = 24/4 = 6

there we have a whole number, this means that at the 3/4 mile marker, we will see the sixth green ribbon, then we have a green ribbon in this marker.

now with the blue:

(3/4)/(1/4) = (3/4)*4 = 3

At the 3/4 mile marker, we will see the third blue ribbon, then there is a blue ribbon in this marker.

Then we know that in the 3/4 mile marker, there are a green and a blue ribbon.

Phil and Nick are selling fruit for a fundraiser. Customers can buy small and large boxes of tangerines. Phil sold 11 small boxes and 10 large boxes of tangerines for a total of $146. Nick sold 5 small boxes of tangerines and 12 large boxes of tangerines for a total of $126. Write the systems of equations.
What is the cost of a large box of tangerines?

Answers

Answer:

11s + 10l = 146

5s + 12l = 126

$8

Step-by-step explanation:

Let :

Small box = s

Large box = l

11s + 10l = 146 - - - - (1)

5s + 12l = 126 - - - - (2)

Multiply (1) by 5 ; (2) by 11

55s + 50l = 730

55s + 132l = 1386

Subtract

-82l = - 656

l = 8

11s + 10(8) = 146

11s + 80 = 146

11s = 66

s = $6

Hence, the price of a large box of tangerine = $8

Tom gets $12 off a box of chocolates that had an original priceof $48. What percentage is the discount?

Answers

Well you can just start off by doing 48/12 which is 4. So he got 1/4 off the box of chocolates, and 1/4 in percentile form is 25%. 
He got a discount of 25%
One way to calculate this is finding what the percentage of 36 is out of 48.
 
36/48= 0.75

You then have to subtract this number from 1 (since you're asking for a markdown, not up) and get 0.25.

0.25 x 100 = 25%

The discount is therefore 25%

Alternatively, you could subtract 36 from 48 to get 12, the amount it was marked down by. Then find the percentage of 12 out of 48.

12/48 = 0.25

0.25 x 100 = 25%

Hope this helps :)

John needs to make a scale drawing of his school building for art class. If the building is 256.25 meters long, and John scales it down using a ratio of 25 meters to 1 inch, how long will the building be in the sketch?

Answers

So we want to know how long will the scale drowing of the building be if the building is 265.25m long and the scale is 1 inch on the drawing is equal to 25 meters of the building. To find the answer lets scale the building. If the real length of the building is 256.25 meters, then the number of inches will be: 256.25/25=10.25 inches.
