Answer:
35280ways
Step-by-step explanation:
let X be the number of ways the letters can be arranged with no restriction,
let M be the number of ways they can be arranged if the letters C and O must stand together,
and let the number of ways the letters C and O can be arranged if they can not stand together.
X=8!
M= 7!
N=X–M=8!–7!=35280 ways
Answer:
The mean of this distribution is 36 years.
Step-by-step explanation:
When the distribution is normal, we use 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 question, we have that:
There is a 0.02275 probability that the age of any randomly chosen person in the department is less than 22
This means that when X = 22, Z has a pvalue of 0.02275. So when X = 22, Z = -2. So
The mean of this distribution is 36 years.

Yes it is because you multiplied 3.4 by 10 and that gives u 0.34
Given that, Joe travels 68 mi in 4 hours, the number of miles Joe will travel in 45 minutes is 12.75.
<h3>How many miles did joe travel in 45 minutes?</h3>
Given that;
- Joe travels 68 miles in 4 hours
- joe travel x miles in 45 minutes
First, we convert 4 hours to minutes: 4 × 60 = 240 minutes
Now,
Joe travels 68 miles in 240 minutes
Joe will travel x miles in 45 minutes
We have;
x × 240 = 68 × 45
x × 240 = 3060
x = 3060 / 240
x = 12.75 miles.
Given that, Joe travels 68 mi in 4 hours, the number of miles Joe will travel in 45 minutes is 12.75.
