Research studies show that the relationship between the tire pressure of a vehicle's tires and the life of the tires is quadratic. The following table shows data for the tire pressure of a car's tires (in pounds per square inch) and its
average tire life (in thousands of miles).

Use a graphing or online regression calculator to find the quadratic function of best fit for this set of data. Then, predict
the tire life for this vehicle's tires given that the tire pressure is maintained at 30 psi (pounds per square inch).
47,800 miles
48,800 miles
50,800 miles
51,800 miles

they go with it happens or they mite give a chance?

step-by-step explanation:

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )
