Consecutive even integers are 2 apart
they are
x,x+2,x+4
total sum is 60
x+x+2+x+4=60
3x+6=60
minus 6 both sides
3x=54
divide both sides by 3
x=18
x+2=20
x+4=22
the ages are
18,20,22
Answer:
e^(ln x) is just plain x
Step-by-step explanation:
The functions f(x) = e^x and g(x) = ln x are inverses of one another. In other words, one "undoes" the other.
Thus, as the rule goes, e^(ln x) is just plain x.
Here, e^(ln x) = 4 simplifies to x = 4.
Y=5+4x

Step-by-step explanation:
According to the sample size, it will be necessary to approximate the data through the normal distribution and through this calculate the standard deviation to obtain both the average, the standard deviation and the obtained deviation. Here the sample size is 40.
Approximately the distribution of proportion is a Normal distribution using the CLT. the mean will be 0.78, then we have that the standard deviation is,



Then the distribution will be normal with the values of 0.78 to 0.0655 for the mean and the standar deviation respectively.
<em>Normal (0.78,0.0655)</em>
