Answer:
x = 16
Step-by-step explanation:
10 : 15 5:15 5 x 3 : 15 15:15
x : 24 x/2 : 24 (x/2) x 3 : 24 3x/2 :24
3x/2 = 24 multiply both sides by 2
3x = 48 divide both sides by 3
x = 16
Answer:
NP = 
Step-by-step explanation:
Since MP is an angle bisector then it divides the sides/ base in the ratio.
=
, substitute values
=
( cross- multiply )

Answer:
At least 832 teenargers must be interviewed.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so
Now, find the margin of error M as such
In which
is the standard deviation of the population and n is the size of the sample.
How many teenagers must the firm interview in order to have a margin of error of at most 0.1 liter when constructing a 99% confidence interval
At least n teenargers must be interviewed.
n is found when M = 0.1.
We have that 
So




Rounding up
At least 832 teenargers must be interviewed.
