Answer:
For the 99th percentile, we have X = 206 seconds.
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:

99th percentile:
Value of X when Z has a pvalue of 0.99. So we use 




For the 99th percentile, we have X = 206 seconds.
Answer:
first choice
Step-by-step explanation:
make 1/3 and 1/2 a common denominator, which is 6.
1x2
- = 2
-
3x 2 6
1 x 3
- = 3
-
2 x 3 6
now u have 2/6, and 3/6
u subtract 2/6 by 3/6 since ur finding a solution to an inequality. remember to do the opposite sign.
2/6-2/6 = 0 (u cancel that out)
3/6 - 2/6 = 1/6
now u have
q>1/6
since there's no 1/6 the first choice is the most accurate
Answer:
A
Step-by-step explanation:
Answer: The answer is 896.
Step-by-step explanation: There are several ways to answer this. If you multiply both the 28 and the 32 you get the final answer 896 quickly.
However there are different ways to get the answer that aren't as quick as this one.
First we multiply.
<em>30*20=600 </em>
Then we continue multiplying.
<em>8*30=240 </em>
<em>20*2=40 </em>
<em>8*2=16 </em>
Then we add all the values up starting with the hundreds
<em>600+240=840. </em>
<em>40+16=56</em>
Finally we add both of the values up and we get our answer <em>840+56=896. </em>
<u><em>A=896 Hope this helps!</em></u>
