Which is the residual vaulewhen x=2
The answer would be -1
koban [17]3 years ago
5 0

The residual value is the vertical distance between the observed value and the predicted value. In other words,

residual value = point in scatter plot - point in the line of best fit

When x=2, the corresponding scatter plot point is at y=1 and the corresponding point in the line of best fit is y=2 [can be seen from the graph]

Hence,

residual value = 1-2=-1. Answer choice B is correct.

A maple syrup producer would like to increase production by 500 gallons per each consecutive year with a goal of producing at le
ipn [44]

Answer:

b) x ≥ 3000 gallons

Step-by-step explanation:

Part a)

Production of Year 1 = x gallons

By each year the producer will increase the production by 500 gallons. So,

Production in Year 2 = x + 500 gallons

Similarly,

Production in Year 3 = x + 500 + 500 = x + 1000 gallons

Production in Year 4 = x + 1000 + 500 = x + 1500 gallons

Production in Year 5 = x + 1500 + 500 = x + 2000 gallons

Part b)

The maple syrup producer wants to produced atleast 20,000 gallons in 5 years.

Total amount produced in 5 years = x + x + 500 + x + 1000 + x + 1500 + x + 2000

Total amount produced in 5 years = 5x + 5000

Since, producer wants total production to be atleast 20,000, we can set up the inequality as:

5x + 5000 ≥ 20000

Subtracting 5000 from both sides, we get:

5x ≥ 15000

Dividing both sides by 5, we get:

x ≥ 3000

This means, in the first year the production of maple syrup must be atleast 3,000 gallons i.e 3000 gallons or more to have a total of atleast 20,000 gallons in 5 years.
