Please answer!! I’ll mark Brainiest!! Anika is on the crew to set up rides for the state fair. The crew does most of the setup o

n the day that the
Tale anives at the fairground and then continues to work on finishing the setup for about a week to have the
rides ready to go in time for the opening of the fair. The scatter plot shows Anika's setup time on different
days and the linear model for the data

Answer:

Step-by-step explanation:

Answer:

(a) We will form an equation of line from the points given (6,10) and (2,15)

Using:

On substituting the values in the formula above we will get the required equation of line.

On simplification we will get:

(b) We need to tell at day 0 put x=0 in above equation:

Anika worked for 70 hours on the set up crew on the day the fair arrived at the fairgrounds day 0.

Now, we need to tell decrease per day which is equal to the slope of line

To find the slope compare the equation with general equation which is y=mx+c where m is slope

Here, in

 which is the decrease per day.

pogonyaev
R of Earth = R of Saturn - 51,853.9 km
6,378.1 km = R - 51,853.9 km
R = 6,378.1 km + 51,853.9 km
R = 58,232 km.

Complete the sentence to finish the explanation of how you could show that points A, B, and C on the coordinate plane are collin
rosijanka [135]

Answer:

  • <u>First blank: the equation of the line that passes through A and B</u>

<u></u>

  • <u>Second blank: is a solution of the equation</u>

Explanation:

Three or more points are collinear if and only if they are on the same line, and, thus they are solutions, of the same equation of the line.

When you know two points through their coordinates you can always find the equation of the line:

  • Point A (x₁, y₁)
  • Point B (x₂, y₂)

You can find the slope, m, of that line by using the slope formula:

  • m = rise / run = Δy / Δx = (y₂ - y₁) / (x₂ - x₁)

And then, you apply the point-slope equation:

  • y - y₁ =  m (x₂ - x₁)

Since you know m, x₁, and y₁, your equation is determined.

Once you have your equation, substitute the x and y coordinates with the coordinates of the point C. If, and only if, the equation is satisfied, the point C is on the same line and the three points are collinear.

Sasha is becoming a stronger runner. Last year she ran five miles in 50 minutes. This year her timing improved by 20%. How long
olga55 [171]

Answer:

40 minutes

Step-by-step explanation:

Last year she ran five miles in 50 minutes

This year her timing improved by 20%. This means she runs 5 miles in 20% less time than last year

How long does it take her to run five miles?

= 50 minutes - 20% of 50 minutes

= 50 minutes - 20/100 * 50 minutes

= 50 minutes - 0.2 * 50 minutes

= 50 minutes - 10 minutes

= 40 minutes

This year, it takes her 40 minutes to run 5 miles
