Answer:
C. 6 because any answer besides that is too low or too high.
Step-by-step explanation:
110.25 pitches so far- 150 at max. 5.75 pitches per game.
4: 4x5.75 = 23
110.25 + 23 = 133.25
5. 5x5.75 = 28.75
110.25 + 28.75 = 139
6: 6x5.75 = 34.5
110.25 + 34.5 = 144.75
7: 7x5.75 = 40.25
110.25 + 40.25 = 150.50 > which rounds up to 151
9/14 stays the same
2/7 turns into 4/14
1/ into 7/14
all of them added is 20/14
simplified is 1 3/7
Answer:
The bulbs should be replaced each 1436.9 hours.
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 problem, we have that:

How often should the bulbs be replaced so that no more than 1% burn out between replacement periods?
This is the first percentile of hours. So it is X when Z has a pvalue of 0.01.
So it is X when Z = -2.33.




The bulbs should be replaced each 1436.9 hours.
Answer:
<h2>True</h2>
Step-by-step explanation:
1 meter = 100 centimeters
therefore 2m = 2(100cm) = 200cm
