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:
Step-by-step explanation:
The Cylindrical coordinates are:
x = rcosθ, y = rsinθ and z = z
From the question, on the xy-plane;
where:
0 ≤ r ≤ and 0 ≤ θ ≤ 2π
∴
Answer:
(2,-4)
Step-by-step explanation:
Just plug in the numbers
6(2)- (-4)/2=14
12- -2=14
14=14
