Before we start sticking a bunch of x's in these things, let's remember what they are.
Look at a few examples:
| 5 | = 5
| 0 | = 0
| -3 | = 3
So...
What do absolute values do to positive numbers?
NOTHING!
What do absolute values do to 0?
NOTHING!
What do absolute values do to negative numbers?
MAKE THEM POSITIVE!
That's it, Baby! That's as hard as it gets!
Why are the answers to absolute value guys never negative?
Because absolute values are distances!
The surface area of a cube is simply the area of one face multiplied by 6, since all of the 6 faces are exactly the same, therefor:
Surface area = 5*5*6 = 150 ft^2
A confidence interval that will capture the true population mean with 95% confidence. The value is ( 23.6459 , 24.8293 ) .
What is population mean?
A population in statistics is a group of comparable objects or occurrences that are relevant to a particular topic or experiment. A statistical population can be a collection of real things or a hypothetical, possibly limitless collection of objects derived from experience.
Data: 18
for given data
as population variance is unknown so we used sample variance
Now
hence 95 % of population mean is
As n=101 which is large so critical value is 1.98397

Answer:
The correct answer is 30 miles.
Step-by-step explanation:
Porter is driving due east to point, say B, from his initial point, say A, for about 20 miles. Therefore AB = 20 miles.
He is driving due south to point, say C, from B, for about 23 miles. Therefore BC = 23 miles.
Therefore the distance between A and C is given by the Pythagoras theorem,
⇒ AC = = = 30.479 miles ≈ 30 miles.
Therefore Porter is 30 miles away from his initial point, to the nearest hundredth of a mile.
