What is the range of f(x)=3x+9

Answer:

20 cm

Step-by-step explanation:

each side of each triangle is 5. You can label all of the sides. They'll each be 5.

5 + 5 + 5 + 5 = 20

Answer:

Step-by-step explanation:

Let's use the variable Y to represent the length of time (in seconds) that the traffic light remains yellow at a speed of x miles per hour. According to the information given, the time the light is yellow (Y) is 1 second more than 0.05 times the speed limit (x). We can write this as:

Y = 0.05x + 1

In this equation:

Y represents the length of time the light is yellow in seconds.

x represents the speed limit in miles per hour.

The equation shows that the time the light is yellow increases linearly with the speed limit, with an additional 1-second buffer.

Answer:

Model D is least likely to have a brake failure.

Step-by-step explanation:

since when we will compare all the values of the probability of brake failure for the models in % by the following table:

Car Model           Brake Failure

                                   in New Car

A                              0.0065%

B                              0.0037%

C                                 0.0108%

D                                 0.0029%

 E                                 0.0145%

Total                      0.0048%

We will see that 0.0029% is the least percent among all the other entries.

Hence car model D is most likely to have a least chance of brake failure.

Answer:

-0.02

Step-by-step explanation:

To find the mean (average) of a set of numbers, you add up all the numbers and then divide by the total count of numbers. In this case, you have four numbers: -0.05, 0.09, -0.04, and -0.08.

Mean = (Sum of the numbers) / (Total count of numbers)

Mean = (-0.05 + 0.09 - 0.04 - 0.08) / 4

Now, calculate the sum of these numbers:

Mean = (-0.05 + 0.09 - 0.04 - 0.08) = -0.08

Now, divide the sum by the total count of numbers, which is 4:

Mean = -0.08 / 4 = -0.02

So, the mean of the numbers -0.05, 0.09, -0.04, and -0.08 is -0.02.
