Answer:

Option: A is the correct answer.

A. y = -1.893x + 31.901

Step-by-step explanation:

We are given a table of values as:

x         y

2       30

5       19

7       20

12       9

16       2

Now clearly from the set of values we see that with the increasing value of x the y-value is decreasing this means that the correlation is negative.

Hence, the slope of the line of best fit will be negative.

Hence, option: B and option: C are discarded.

Hence, when we plot the data values in a scatter plot.

We see that the equation of line of best fit is:

y=-1.893x+31.901

The container that holds the water for the football team is 2/9 full. After pouring in 12 gallons of water, it is 2/3 full. How
Luden [163]

Answer:

27 gallons

Step-by-step explanation:

Our equation is: \frac{2x}{9} +12 = \frac{2x}{3}

What do we need to find: x

We need to first find x, so lets find x first.

12 =  \frac{2x}{3}  -  \frac{2x}{9}

=> 12 = \frac{6x}{9} - \frac{2x}{9}

=> 12 = \frac{4x}{9}

=> x = 27

Lets go back to our equation.

\frac{2(27)}{9} +12 = \frac{2(27)}{3}

We are going to simplify this before solving this. We are going to get:\frac{54}{9} +12 = \frac{54}{3}

=> 18 = 18

Therefore, we found x and we checked that our x value is correct. Now, we need to find how many gallons can the container can hold.

\frac{3x}{3} = a                                                           [a = gallons can the container hold]

=> x = a

Basically that means the container can hold 27 gallons of water.

Please give me brainliest if this is helpful ;D

A box is filled with candies in different colors. There are 40 white candies, 24 green ones, 24 yellow ones, 12 red ones, and 20
AleksAgata [21]

Answer:

3/10 or 30% chance red and green being pulled

Step-by-step explanation:

to get your fraction you do your amount wanted pulled (red and green) over the amount total (all of the colors)

24 + 12 = 36

40 + 24 + 12 + 24 + 20 = 120

36/120 now reduce 6

6/20 reduce by 2

3/10

If x:y = 2:5, find the value of (-x+3y):(2x+y)
Anit [1.1K]

Answer:

let x=2t and y=5t

-x+3y = -2t+15t = 13t

2x+y = 4t+5t = 9t

So the ratio is 13t : 9t

So, the ratio is 13 : 9

The height of a certain banner is equal to one third of its length. If the banner is 5 ft tall, write the equation that can be u
pav-90 [236]

Answer:

L=3h

Step-by-step explanation:

Let height of a banner be h, then we know that this is \frac{1}{3} of the length L of the banner; so we have

h=\frac{1}{3} L .

Now we can rearrange this equation to solve for the length of the banner given it's height:

L=3h

So there we have it!

If the banner is 5 ft tall, then it's length will be:

L=3*5=15ft
