Determine the mean of the numbers 6, 17, 22, 28, and 37.

Kipish [7]

To find the mean or the avg you add up all the numbers you have and then divide by how many numbers you added together in this case 5

$6+ 17+22+28+37=110$

$\frac{110}{5} =22$

so the mean is 22, hope this helped you!

Two drivers, Alison and Kevin, are participating in a drag race. Beginning from a standing start, they each proceed with a const

Vilka [71]

Answer:

Alison wins against Kevin by 0.93 s

Step-by-step explanation:

Alison covers the last 1/4 of the distance in 3 seconds, at a constant acceleration $a_a$ , we have the following equation of motion

$s/4 = a_at_a^2/2$

where s (m) is the total distance, ta = 3 s is the time

$s = 4a_a3^2/2 = 18a_a$

$a_a = s/18$

Similarly, Kevin overs the last 1/3 of the distance in 4 seconds, at a constant acceleration $a_k$ , we have the following equation of motion:

$s/3 = a_kt_k^2/2$

tk = 4 s is the time

$s = 3a_k4^2/2 = 24a_k$

$a_k = s/24$

Since $a_a = s/18$ we can conclude that $a_a > a_k$ , so Alison would win.

The time it takes for Alison to cover the entire track

$s = a_aT_a^2/2$

$T_a^2 = 2s/a_a = 2s/(s/18) = 36$

$T_a = \sqrt{36} = 6 s$

The time it takes for Kevin to cover the entire track

$s = a_kT_k^2/2$

$T_k^2 = 2s/a_k = 2s/(s/24) = 48$

$T_a = \sqrt{48} = 6.93 s$

So Alison wins against Kevin by 6.93 - 6 = 0.93 s

[Right Triangle Only] sin∅ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Define

We have a right triangle. We can use trig to find the angle.

Step 2: Identify Variables

Angle = x

Opposite = 15

Hypotenuse = 23

Step 3: Find Angle x

Substitute: sinx° = 15/23
Inverse: x° = sin⁻¹(15/23)
Evaluate: x = 40.7057°
