Find the probability that a Type A bulb lasts at least 300 hours and a Type B bulb lasts at least 400 hours.
barxatty [35]

Answer:

P(X>3)P(X>4)=(1-F_1(3))(1-F_2(4))

Step-by-step explanation:

We require more information by I will explain in principle:

If Type A has at least 300 hours and Type B at least 400 hours.

(X>3)(Y>4)=P(X>3)P(X>4)

You need to determine the Probability density function of X and Y and then subtract 1 from both

P(X>3)P(X>4)=(1-F_1(3))(1-F_2(4))

This will give you the probability of the expression.

The graph below shows the distance, y, that a car traveled in x hours:
Vika [28.1K]
This is a linear relationship as the rate of change is constant, ie constant velocity.  And the slope represents the velocity, and slope is:

m=(y2-y1)/(x2-x1)

m=(50-25)/(2-1)=25/1

m=25

So the rate of change is 25 mph

Question:

What is the area of the

rectangle?

(rectangle is 5/7 ft wide and 3 1/2 ft long)

Enter your answer as a mixed number in simplest form in the box.

Answer:

2 1/5

Step-by-step explanation:

Because we are finding the area we are multiplying and the formal is L x W = Area so the Length is 3 1/2 and the width is 5/7 so we multiply them and we get: 2.5

3 1/2 x 5/7 = 2.5 let make it a mixed number  5/2 let simplify it now 5 divided by 2 = 2 1/5

is the answer
