Bob and Doug are both 100-meter sprinters. Bob's sprint time is normally distributed with a mean of 10.00 seconds and Doug's spr

Answer:

The standard deviation (σ) = 0.05

Step-by-step explanation:

The question is to find the standard deviation.

STEEP 1: FIND THE MEAN

(10+9.9) ÷ 2 = 9.95

STEP 2: SQUARE THE DIFFERENCE BETWEEN SPRINT TIME AND MEAN

10-9.95= 0.05

0.05^2 = 0.0025

9.9 - 9.95= -0.0025

-0.0025^2 = 0.0025

STEP 3: FIND THE VARIANCE

0.0025+0.0025= 0.005

0.005/2= 0.0025

STEP 4: FIND THE STANDARD DEVIATION (σ )

√variance

√0.0025 = 0.05

Therefore

σ = 0.05.

From the standard deviation, the percentage probability of the higher value to occurs is

0.05×100= 5%

That means Doug has 95%

And Bob has 5%

Solve for v. v + 3/8 = -1/4

IceJOKER [234]

v + 3/8 = -1/4
v = -1/4 - 3/8
v = - 2/8 - 3/8
v = -5/8

What are the x and y- intercepts for the line 4(y+3)=−2(x+6)? Please give an actual answer.

kow [346]

Hello!

X and Y intercepts are found when graphing an equation. You know the X and Y intercepts by when a point crosses the X axis, and for the Y intercept, when a point crosses the Y axis.

First off we must simplify the equation.

4y + 12 = -2x - 12

Here is the photo of the graph attached.

By looking at the graph we can see the answer is...

X intercept = (-12,0)
Y intercept = (0,-6)
