Answer:

4

Step-by-step explanation:

  • 2r = 5s/2 - s/4                    ⇒ bring to common denominator
  • 2r = 10s/4 - s/4
  • 2r = 9s/4
  • 9s = 8r                                ⇒ multiply both sides by 4
  • s = 8r/9                               ⇒ divide both sides by 9
  • s = 8/9*9/2                         ⇒ replace r with 9/2, simplify
  • s = 4                                    ⇒ answer

Question 1-3
Vikki [24]

The production graph of the company is a quadratic graph

The true statements about the production graph are:

  • When producing 5,000 sets of headphones per week, the weekly earnings is $0.
  • Producing 2,500 sets of headphones per week will give the maximum amount of weekly earnings.
  • The maximum possible earnings is about $6,250 per week.
  • If production is increased from 1,500 to 2,000 sets of headphones per week, then the weekly earnings will also increase

<h3>How to interpret the model?</h3>

To interpret the model, we simply evaluate the options one after the other

<u>Producing 5000 sets weekly</u>

From the graph, we have:

(x,y) = (5000,0)

This means that a weekly production of 5,000 sets of headphones give an earning of $0.

Hence, this option is true

<u>Increased production from 3000 to 4000</u>

From the graph, the function value decreases when x increases from 3000 to 4000.

This means that this option is false

<u>Producing 2500 sets</u>

The production of 2500 sets give a maximum earning of $6250

This means that options (c) and (d) are true

<u>Increased production from 1500 to 2000</u>

From the graph, the function value increases when x increases from 1500 to 2000.

This means that this option is true

Hence, the true statements are: (a), (c), (d) and (e)

PLEASE HELPP!!
Rasek [7]

Answer:

Given:

Two trail maps:

Trail on the first map = 8 cm

Trail on the second map = 6 cm

Scale on first map = 1 cm : 2 km

A) What is the scale factor from the map to the actual trail?

For the first map, the scale factor is 1 cm: 2km. Therefore the actual trail is 8 centimeters * 2 kilometers = 16 km.

The scale factor of the second map is 16 km / 6 cm = 2.67 km : 1 cm

B) The length of the actual trail is 16 kilometers.

HELP PLEASE WILL GIVE BRAINLIEST WORTH 50 POINTS
Alja [10]

Answer:

y = 8.13 x -16125.713


hope it helps

Step-by-step explanation:

Sum of X = 14004

Sum of Y = 977

Mean X = 2000.5714

Mean Y = 139.5714

Sum of squares (SSX) = 53.7143

Sum of products (SP) = 436.7143

Regression Equation = ŷ = bX + a

b = SP/SSX = 436.71/53.71 = 8.13032

a = MY - bMX = 139.57 - (8.13*2000.57) = -16125.71277

ŷ = 8.13032X - 16125.71277
