Complete question:
<em>Write the verbal statement as an equation using x as a variable. Then solve. 2 more than 3 times a number is 17.
</em>
<em />
The required expression is 3x + 2 = 17 and the value of x is 5
Let the unknown number be x
- 3 times a number is expressed as 3x
- 2 more than3 times the number is 3x + 2
If the result is equivalent to 17, the required expression will be 3x + 2 = 17
Solve the resulting expression:
3x + 2 = 17
3x = 17 - 2
3x = 15
x = 15/3
x = 5
Hence the required expression is 3x + 2 = 17 and the value of x is 5

Answer:
24.6 < μ < 27.2
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 25.9 - 1.3 = 24.6 pounds.
The upper end of the interval is the sample mean added to M. So it is 25.9 + 1.3 = 27.2 pounds.
So the correct answer is:
24.6 < μ < 27.2
65mph
John drove a total of 200 miles (40mph•5)
655-200= 455 miles
Charlie drove this in seven hours, and 455mi/7hours = 65mph
In mathematics, a unit circle is a circle of unit radius—that is, a radius of 1. Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane.
