100m= 0.621371 miles 11 seconds = 0.0030556 hours v=d/t

<span>0.0621371miles/0.0030556hour=20.3355miles/hour</span> So with the significant digits the answer would be 20.3 miles/hour. Therefore, this answer should be correct

Sabendo que x2 + y2=74 e que xy=35, calcule valor de (x - y2)2

Ann [662]

To solve this problem you must apply the proccedure shown below:

1. You have the following information given in the problem above:

- x²+y²<span>=74
xy=35

2. Therefore, you have that (x-y)</span>² is:

=(x-y)²
=x²-2xy+y²
=(x²+y²)-2xy

3. When you substitute the values given in the problem, you obtain:

=74-2(35)
=74-70
=4

4. Therefore, as you can see, the correct answer is: 4

The web logs of a certain website show that the average number of hits in an hour is 75 with a standard deviation equal to 8.6.

Wittaler [7]

Answer:

a) There is a 10.75% probability of observing less than 60 hits in an hour.

b) The 99th percentile of the distribution of the number of hits is 95.21 hits.

c) There is a 24% probability of observing between 80 and 90 hits an hour

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by

$Z = \frac{X - \mu}{\sigma}$

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. The sum of the probabilities is decimal 1. So 1-pvalue is the probability that the value of the measure is larger than X.

In this problem, we have that

The web logs of a certain website show that the average number of hits in an hour is 75 with a standard deviation equal to 8.6, so $\mu = 75, \sigma = 8.6$ .
