Answer:
60%
Step-by-step explanation:
36/60 x 100= 60%
Step-by-step explanation:
100% = 4.25
1% = 100%/100 = 4.25/100 = 0.0425
how many % are 3.4 ?
we find this by calculating how often 1% (0.0425) fits into 3.4.
3.4 / 0.0425 = 80 %
We have been given that the ages of students in a school are normally distributed with a mean of 15 years and a standard deviation of 2 years.
We are asked to find the percentage of students that are between 14 and 18 years old.
First of all, we will find z-score corresponding to 14 and 18 using z-score formula.




Similarly, we will find the z-score corresponding to 18.



Now we will find the probability of getting a z-score between
and
that is
.

Using normal distribution table, we will get:


Let us convert
into percentage.

Therefore, approximately
of the students are between 14 and 18 years old.
Hello there!
The answer to your question is A. <span>1.75 in.</span>³
The ball split, so now the diameter is 1.50 in. The radius is always half of the diameter. So now, do the volume formula for a sphere. You answer should turn out to be A.
Hope I helped!
