Estimate the line of best fit using two points on the line 100 90 80 70 (e, 80) 60 30 20 10 (2.20) 10 O A. y= 2x O B. y = 2x+10
nexus9112 [7]

Answer:

y = 10x

Step-by-step explanation:

Given

The attached plot

Required

The line of the best fit using (8,80) and (2,20)

We have:

(x_1,y_1) = (8,80)

(x_2,y_2) = (2,20)

Calculate slope (m)

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{20 - 80}{2- 8}

m = \frac{-60}{-6}

m = 10

The equation is then calculated using:

y = m(x - x_1) + y_1

y = 10(x - 8) + 80

Expand

y = 10x - 80 + 80

y = 10x

Whitepunk [10]
<h3>Answer:</h3>
  • 6 large prints
  • 12 small prints
<h3>Step-by-step explanation:</h3>

<em>Numerical Reasoning</em>

Consider a set of prints that consists of 2 small prints and one large print (that is, twice as many small prints as large). The value of that set will be ...

... 2×$20 +45 = $85

To have revenue of at least $510, the studio must sell ...

... $510/$85 = 6

sets of prints. That is, the studio needs to sell at least 6 large prints and 12 small ones.

_____

<em>With an equation</em>

Let x represent the number of large prints the studio needs to sell. Then 2x will represent the number of small prints. Total sales will be ...

... 20·2x +45·x ≥ 510

... 85x ≥ 510

... x ≥ 510/85

... x ≥ 6

The studio needs to sell at least 6 large prints and 12 small prints.
