Answer:
198
Step-by-step explanation:
π rad=180
==> 1.1π rad gives 1.1π× 1/π×180=198
Answer:
x = 30
Step-by-step explanation:
Since RQ bisects ∠ PRS, then
∠ SRQ = ∠ PRQ , substitute values
3x - 20 = x + 40 ( subtract x from both sides )
2x - 20 = 40 ( add 20 to both sides )
2x = 60 ( divide both sides by 2 )
x = 30
Answer:

We can use the z score formula given by:

And replacing we got:

And using the normal standard distribution and the complement rule we got:

Step-by-step explanation:
For this case w eknow the following parameters:
represent the mean
represent the deviation
n= 32 represent the sample sze selected
We want to find the following probability:

We can use the z score formula given by:

And replacing we got:

And using the normal standard distribution and the complement rule we got:

Answer:
x = 10
Step-by-step explanation:
You know z = x+4, so ...
3z -x/2 = 37 . . . . . . . . the given relation
3(x +4) -x/2 = 37 . . . . substituting for z
5/2x +12 = 37 . . . . . . .eliminate parentheses and simplify
5/2x = 25 . . . . . . . . . . subtract 12
x = 10 . . . . . . . . . . . . . multiply by 2/5
_____
<em>Check</em>
3z = 3·14 = 42
x/2 = 10/2 = 5
42 exceeds 5 by 37 . . . . true
