Answer:
A. -3.84 meters
Step-by-step explanation:
Given:
A penguin can dive 2% of the total depth every 1 second.
Total depth = 48 meters.
Now we have to find 2% of 48.
=
=
= 0.96 meter
So, the penguin dives -0.96 meters per seconds down the water.
The negative sign represents below the surface of the water.
The total depth of the penguin after 4 seconds = 4 times -0.96
= -3.84 meters
Therefore, the answer is A. -3.84 meters
Answer:
340
Step-by-step explanation:
The first step is finding the percentage of those who fail within 19 months.
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:
The proportion is the pvalue of Z when X = 19. So
has a pvalue of 0.6808.
Jolt is expected to replace 0.6808 of the connectors sold. Out of 500, that is, on average, 0.6808*500 = 340.
Jolt expects to replace, on average, 340 of the connectors sold.
