Answer:

The mean number of customers that will arrive in a five-minute period is 2.

Step-by-step explanation:

a. What is the mean or expected number of customers that will arrive in a five-minute period

For one minute, the mean is of 0.4 customers.

So, using proportions, for 5 minutes, the mean is of 5*0.4 = 2 customers.

The mean number of customers that will arrive in a five-minute period is 2.

11 sq root 45-4 sq root 5
Karo-lina-s [1.5K]
First evaluate the sq root of 45.
To do so, you have to find perfect square factors (2 x 2, 3 x 3, 4 x 4, and etc.)

The factors of 45 are 3 x 3 x 5.

Notice that there is a 3 x 3. That means you can get the 3 out of the square root and multiply with the number outside of the square root.

11(3)square root 5 - 4 square root 5

33 square root 5 - 4 square root 5

Subtracting and Adding square roots is the same thing as subtracting and Adding variables. If they have the same variable you can +/-. So if they have the same square root, then can +/-.

Answer: 29 square root 5

Zx and Zy are supplementary angles. Zy measures<br> 156°<br> What is the measure of Zx?
cupoosta [38]

Answer:

Zx = 24 degrees

Step-by-step explanation:

since it is supplementary it adds up to 180 degrees. so you have part of the angle (156 degrees) so the equation would be 180 - 156 = Zx (origionally Zx + 156 = 180).
