Answer:

True

Step-by-step explanation:

Look at one one point of the original figure. Then move it left 5 units and up 1 unit. Do this for the other 3 units. Since all of the points line up with the second figure, the answer is true.

The time it takes to completely tune an engine of an automobile follows an exponential distribution with a mean of 40 minutes.

Mazyrski [523]

Answer: a. P (x<30) = 0.5276

b. P (30<x<35) = 0.0555

Step-by-step explanation: An exponential distribution is a distribution of time in which events happens at a constant average rate.

The rate is calculated as

$\lambda=\frac{1}{\mu}$

with μ as the mean.

The probability density distribution for this type of distribution is

$f(x)=\lambda e^{-\lambda x}$

And probability is calculated as

$P(X$

For tuning of an engine, the rate is

$\lambda=\frac{1}{40}$

λ = 0.025

a. Probability of less than 30 minutes:

$P(X$

P (X < 30) = 0.5276

Probability of tuning in 30 minutes or less is 52.76%.

b. Probability of between 30 and 35 can be described as

$P(30$

$P(X$

P (X < 35) = 0.5831

P (X < 30) = 0.5276

Then:

$P(30$

P (30 < X < 35) = 0.0555

Probability of tuning an engine between 30 and 35 minutes is 5.55%.

. Write the equation in slope intercept form for the line that goes through point (−10, 8) with slope =6.

Doss [256]

Y = mx + b is slope intercept form

x = -10
y = 8
m = 6

1. Solve for b

8 = (6)(-10) + b
b = 68

2. Plug m and b back into your slope intercept equation

y = 6x + 68
