Answer:
-1.58
Step-by-step explanation:
We have that the mean (m) is equal to 89 and the standard deviation (sd) 2.4
They ask us for P (x <85.2)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / (sd)
We have all these values, replacing we have:
z = (85.2 - 89) / (2.4)
z = -1.58
Answer:
130.00 + 30.00 = $160.00
Step-by-step explanation:
Hi there!
To find x, we'll need to proceed methodically. First, we'll start by finding the length of ST. The 30-60-90 relationship tells us that ST = 2. Then, we can find RT, also using the 30-60-90 relationship. RT = 4. Lastly, we can use the 45-45-90 relationship to determine that x = 4.
Hope this helps!! :)
