In think you actually wanted the answer to the division of 455 by the number 67.
455/67 = 6.791.
For dividing such large numbers, try to go step by step. In this case try the multiplying 67 by 1 first, then by 2, then by 3, then by 4, then by 5, then by 6 and lastly by 7. When you multiply 67 by 7, then you will get 469. So this will show you that you cannot go beyond multiplying with 6. When you multiply 67 with 6 you get 402. hen again try multiplying the remainder and proceed accordingly.
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.
-17/12 want me to explain
Answer:
Where's the figure,my friend?
Answer:
Nine of the times for the first race were at least 16 seconds
Step-by-step explanation:
Here we have from the scatter plot, the times are given as
Time Frequency
19 2
18 2
17 2
16 3
15 1
Therefore, total number of times that are above 16 seconds in the first race is
3 + 2 + 2 + 2 = 9
Therefore, the first option is correct
