Find the measurement of angle A (round to the nearest tenth)
2 answers:
<u>Answer:</u>
The correct answer option is 17.1°.
<u>Step-by-step explanation:</u>
We are given a right angled triangle with two known side lengths of perpendicular and base with respect to the unknown angle A for which we have to find the measure.
For that, we can use the formula of tan which by using the two given side lengths.
Therefore, the measure of the angle A is 17.1°.

Step-by-step explanation:
Problems of normally distributed samples are 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 question, we have that:
How much energy should be required for the bottom 80% of bottled water?
At most the 80th percentile.
The 80th percentile is X when Z has a pvalue of 0.8. So it is X when Z = 0.84.
At most 9.12 joules should be required for the bottom 80% of bottled water
