If he hits it 3/10 times and 10 x 8 = 80 then you would do 3 x 8 = 24

Set up a proportion: 3/10= x/80. Then if you multiply 10 by 8, you get 80 on both sides, But, If you do it to the top, you also have to do it to the bottom, so the anser is 3 x 8 , or 24.

Write the equation of a line that passes through the point (1,4) and has a slope of 9.
Kryger [21]

Answer:

y=9x-5

Step-by-step explanation:

You want to find the equation for a line that passes through the point (1,4) and has a slope of 9.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

To start, you know what m is; it's just the slope, which you said was 9. So you can right away fill in the equation for a line somewhat to read:

y=9x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(1,4). When x of the line is 1, y of the line must be 4.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: b is what we want, the 9 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specifically passes through the point (1,4).

So, why not plug in for x the number 1 and y the number 4? This will allow us to solve for b for the particular line that passes through the point you gave!.

(1,4). y=mx+b or 4=9 × 1+b, or solving for b: b=4-(9)(1). b=-5.The equation of the line that passes through the point (1,4) with a slope of 9

is

y=9x-5

The histogram below shows the number of properties in a town that sold within certain time periods.
Tomtit [17]

Answer:

Option c) The scale on the y-axis misrepresents the difference in the heights of the bars.

Step-by-step explanation:

Given is a histogram that shows the number of properties in a town that are sold within certain periods.

On x axis is given number of days to sell and on y axis the number of properties

X axis is given in interval form with interval width 30 and on y axis scales are marked as 0,1,2....12,13 etc

The mistake is on y axis after 0, 10 is marked with unit distance from 0 but from 10 to 11 also distance is shown as 1 unit.

Hence correct option is

Option c) The scale on the y-axis misrepresents the difference in the heights of the bars.

Write an equation of the line parallel to y=3x+2 that passes through (-1, -2)
Mariulka [41]

Answer:

y=3x+1

Step-by-step explanation:

From the question, we are given;

  • The equation y = 3x + 2
  • A point (-1, -2)

We are required to determine the equation of a line parallel to the given line and passing through the point (-1, -2)

  • We are going to determine the gradient of the line first; when an equation is written in the form of y = mx + c, where m is the gradient.

y = 3x + 2, m₁ = 3

  • But, m₁ = m₂ for parallel lines
  • Therefore, the gradient of the line in question, m₂ is 3
  • With the gradient, m₂=3 , and a point (-1, -2) we can get its equation;

Taking another point (x, y)...

Then;

\frac{y+2}{x+1}=3

y+2=3(x+1)\\y+2=3x+3\\y=3x+1

Therefore; the equation of the line is y=3x+1
