Answer:
1) The equation of the line of best fit is y = 0.3·x + 5
2) The time it would take a player that can complete 22 leg press repetitions to run 40 yards is 11.6 seconds
Step-by-step explanation:
1) The given data are;
Leg press (Reps):
40-yard Dash Time
12
8.6
32
14.6
7
7.1
11
8.3
23
11.9
28
13.4
15
9.5
From the attached graph we observe that with the data sorted in increasing order, there is a linear relation between the number of leg presses and the time to complete a 40 yard dash
The slope = (14.6 - 7.1)/(32 - 7) = 0.3
The equation of the line of best fit is the linear equation of the data given in point and slope form as follows;
y - 7.1 = 0.3×(x - 7)
y - 7.1 = 0.3·x - 2.1
The equation of the line of best fit is therefore;
y = 0.3·x + 5
Where;
y = The time to complete the 40-yard dash
x = The number of leg press completed
2) When x = 22, we have;
y = 0.3 × 22 + 5 = 11.6 seconds
If a player can do 22 leg-press repetitions, it would take the player 11.6 seconds to complete the 40 yard-dash.
Answer:
day and night
Step-by-step explanation:
that is the answer
Plug in 300 for C(x), to get:
300=

Then subtract to get: 0=

Then use the quadratic formula and plug everything in. Use a calculator to simplify.
You'll get two answers: 29.486 and -0.513.
