Step-by-step explanation:
Which one is the height?¿
The formula is
b1+b2 divided by 2 times the height
That's the best I can do for you atm atleast.
Answer:
48°
Step-by-step explanation:
We can solve this using our knowledge on tangents of an angle. Remember, tangents are the opposite leg divided by the leg adjacent to that angle.
This means the tangent of x° =
. Now that we know the tangent ratio, we can find the angle with inverse trigonometric ratios. These kinds of ratios give us the opposite of the tangent - which would lead to the angle measure we're looking for. The equation would look like this:

Using a calculator, the answer would be:

Rounding this to the nearest degree would give us 48° as our answer! I hope this was clear enough.
A and D because x is 1/3y not 3y and x times y would be 48 and yes I'm sure
It should be 185 pounds. Have a GREAT day!!!!! :)
Answer:
The probability that a student arriving at the ATM will have to wait is 67%.
Step-by-step explanation:
This can be solved using the queueing theory models.
We have a mean rate of arrival of:

We have a service rate of:

The probability that a student arriving at the ATM will have to wait is equal to 1 minus the probability of having 0 students in the ATM (idle ATM).
Then, the probability that a student arriving at the ATM will have to wait is equal to the utilization rate of the ATM.
The last can be calculated as:

Then, the probability that a student arriving at the ATM will have to wait is 67%.
