Acollege football coach wants to know if there is a correlation between his players leg strength and the time it takes for them to sprint 40 yard. he sets up the following test records the data.

every day for a week he counts how many times each player can leg press 350 pounds. the following week he has each player sprint 40 yards every day. table shows the average number of leg press repetitions and the average 40 yard dash time (in seconds) for seven randomly selected players. what is the equation of the line of best fit? how many seconds should he expect a player to take to run 40 yards if that player can do 22 leg-press repetitions? round any values to the nearest 10th if necessary

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
