Answer:
-15
Step-by-step explanation:
<u>Definition of absolute value: </u>
<em>Distance from zero on a number line. </em>
<em />
Imagine a number line with 0 in the middle of it. Now mark the number 3 on it. Also mark the <em>opposite </em>of 3, which is -3. What is the <u>distance</u> from zero to those 2 points? it's 3.
This is exactly like saying |3| = 3 and |-3| = 3
Even if the number inside absolute value is negative, it <em><u>simplifies</u></em> to the positive of the same number.

So let's talk about your problem.
-|-15|
> the absolute value simplifies to 15
-|-15| = - 15
So that ends up being your answer.
Hope this helps!!!!!!!
Answer:
a) 18
b) 2.101
Step-by-step explanation:
a) What are the degrees of freedom for Student's t distribution when the sample size is 19?
Degrees of freedom = n - 1
Where n = sample size
= 19 - 1
= 18
b) Use the Student's t distribution to find tc for a 0.95 confidence level when the sample is 19.
(Round your answer to three decimal places.)
We would be determining these using the t distribution table
1 - 0.95 = 0.05 ( for two tailed)
Or
0.05/2 = 0.025(one - tailed)
Hence, the tc(test score) for a 0.95 confidence level when the sample is 19 is 2.101

Answer:
116 c
Step-by-step explanation:
Remember that the total of the angles always equals 180 degrees
4x + 2 + 8 + 6x + 30 = 180
Now solve
4x + 2 - 2 + 8 + 6x + 30 = 180 - 2
4x + 8 - 8 + 6x + 30 = 178 - 8
4x + 6x + 30 - 30 = 170 - 30
4x + 6x = 140
10x = 140
10x ÷ 10 = 140 ÷ 10
x = 14
Now that we know what x is we can fill in the blanks
4(14) + 2
58 + 2
58
Angle O is 58 degrees
8 + 6(14)
8 + 84
92
Angle R is 92 degrees
To check we can add them all up
30 + 58 + 92 = 180
x = 14
