Answer:
14%
Step-by-step explanation:
<em><u>49 parts of 350 parts</u></em> do not need specifications...
= 49/350
So, 49/350 = x/100
= <u>49(100) = 350x</u>
= 4900 = 350x
= 4900/350 = x
x = 14%
Answer:
represents the radius (in cm) of a circle whose circumference is 15 cm
if
, then a represents the circumference (in cm) of a circle whose radius is 15cm
Step-by-step explanation:
In a circle the following relationship can be posed:

Let g be a function that determines the radius of the circle from the value of its circumference, so, you have:

Thus,
represents the radius (in cm) of a circle whose circumference is 15 cm. You have to
.
On the other hand, if
, then
represents the circumference (in cm) of a circle whose radius is 15cm. You have to 
Answer:
Top 5% is 5.84 milliters and the bottom 5% is 5.60 millimeters.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

Top 5%:
X when Z has a pvalue of 0.95. So X when Z = 1.645




Bottom 5%:
X when Z has a pvalue of 0.05. So X when Z = -1.645




Top 5% is 5.84 milliters and the bottom 5% is 5.60 millimeters.
