Y is directly proportional ( x+2)² <br> when x = 8 y= 250 <br> find y when x = 4​
sladkih [1.3K]

Answer:

y=90 when x=4

Step-by-step explanation:

We are given that

y\propto (x+2)^2

When x=8 and y=250

We have to find the value of y when x=4

y=k(x+2)^2

Where k= Proportionality constant

Substitute the values

250=k(8+2)^2

250=100k

k=\frac{250}{100}

k=5/2

Now, substitute x=4 and k=5/2

Then, we get

y=\frac{5}{2}(4+2)^2

y=\frac{5}{2}\times 36

y=90

The Dot plots below show the number of sales made by Jason and Shane at work over the past seven days. Which observation about t
IgorLugansk [536]

Jason's data distribution is symmetrical and shows no outliers; Shane's data distribution is uniform and shows no outliers also. Therefore, the correct observation about the data sets that is correct is:<em> Option B.</em>

<h3>Symmetrical and Uniform Data Distribution on a Dot Plot</h3>
  • If the data plotted on the dot plot shows a bell shape curve and can be divided into equal halves by a vertical line, the data distribution is symmetrical.
  • When the data is spread equally across the range with no clear peaks, the data distribution is uniform.

<h3>What are Outliers?</h3>

Outliers are values that are far from the middle and are entirely different from the rest of the data.

The dot plots for sales made by Jason and Shane are shown in the image attached below.

Jason's data distribution is symmetrical and shows no outliers; Shane's data distribution is uniform and shows no outliers also. Therefore, the correct observation about the data sets that is correct is:<em> Option B.</em>

Travka [436]
One way to do this is to use ratios
another way is to graph it

if you use ratios then
1:25=5:125
1/25=5/125
1/25=1/25
therefor theya re in same ratios
(x,y)=(1,25)
find (3,y)
1:25 =3:y
1/25=3/y
multiplyh both siddes by y
y/25=3
multiply both sides by 25
y=75
the point is (3,75)
