O B. An inherent zero is a value that the variable can take.
Ос.
An inherent zero is a zero that implies none
Answer:
An inherent zero is a zero that implies none
Step-by-step explanation:
A zero which means that a phenomenon or variable does not exist or isn't represented is called inherent zero. It simply implies none.
Datasets that have inherent Zero:
1. Average age of participants In years
2.) Rainfall height in inches during rainy period
3.) Speed of wind during a storm.
Datasets with no inherent zero :
Dataset which involves measuring constructs usually have no inherent zero, such as :
1.) Average IQ level in a group of students
2.) Average level of satisfaction
3.) measurement involving temperature

( I need it by 10/20)
=====================================================
Explanation:
C is the midpoint of AB. This means AC is half as long as AB
Put another way, AB is twice as long as AC
AB = 2*AC
AB = 2*( AC )
32 = 2*( x/2 + 10 ) .... substitution
32 = 2*(x/2) + 2*10 ... distribute
32 = x + 20
x+20 = 32
x = 32-20 .... subtract 20 from both sides
x = 12
---------
If x = 12, then
AC = x/2 + 10
AC = 12/2 + 10
AC = 6+10
AC = 16
which is half of AB = 32, so it confirms our answer.

Sam bought brushes for $8, a palette for $5, and oil paints for $15. He paid $29.82 in all. What sales tax rate did Sam pay?
A.
0.06%
B.
0.65%
C.
6.5%
Answer:
6.5%
Step-by-step explanation:
Total cost before tax
= Cost of Brushes + Cost of Palette + Cost of paint
= 8 + 5 + 15
= $28.00
It is given that in total, he paid $29.82
Hence the amount he paid in taxes
= Total amount paid - total cost before tax
= $29.82 - $28.00
= $1.82
Therefore, sales tax rate
= (taxes / cost before tax ) x 100%
= (1.82 / 28) x 100%
= 6.5%
Answer:
C)6.5%
Step-by-step explanation:
so first you have to add up all the items, then u get 28.00, then what i did was i subtracted 29.82 and 28.00 i got 1.82. and 6.5 equals 1.82 so yea.

Answer:
#1) 25 degrees #2) 155 degrees #3) 25 degrees #4) 25 degrees #5) 5x+15= 110
Step-by-step explanation:
basically the use the vertical angle relationship to figure it out
that would mean that 4=155 and 3=1 and since the relationship is straight angle pair it means that 155+ x= 180 180-155= 25
5) CDE= FDG this is the vertical angle rule so 5x+15= 8x-42
solve that by adding like terms, 5x-15= 8x-42 +15 by doing adding to both sides it eliminates the 15 because you added it with the like terms, -42 and got -57
-57+8x= 5x now subtract 8 on both sides, -57= -3x divide and it equals 19
now plug that back into the eqaution of 5x+15 5(19)= 95 + 15= 110
What is the slope of a line that passes through the points (0, 3) and (5,96)
Answer:

parallel to the line 3x + 5y = 15?
9514 1404 393
Answer:
3x +5y = -30
Step-by-step explanation:
The parallel line can have the same x- and y-coefficients. You can find the value of the new constant by using the given point for x and y:
3x +5y = 3(-5) +5(-3) = -30
3x +5y = -30

What is 68% of 118
Show work
Answer:
80.24
Step-by-step explanation:
The easiest way to do this is to convert 68% to a decimal and multiply by 188. To convert a percent into a decimal, all you have to do is move the decimal point twice to the left. So...
68%=.68 Now, we can multiply by 118.
.68x118=80.24 68% of 118 is 80.24!

5(-3p + 7) + 5(p - 1)
Answer:
The answer would be -10p+30.
Step-by-step explanation:
Distrubuting the 5 to -3p and 7 and 5 to p and -1 would be the first step.
Once you did that, you would get -15p+35+5p-5. Now just add -15p to 5p and add 35 to -5 and you'll get -10p+30.
A line contains the points (82, -96) and (87, -86)
What is the slope of the line in simplified form?
A. -2
B. 1/2
C. 2
D. -1/2
==================================================
Explanation:
Subtract the y coordinates
y1-y2 = -96-(-86) = -96+86 = -10
Subtract the x coordinates in the same order
x1-x2 = 82-87 = -5
Divide the two differences to get the slope m
m = (y1-y1)/(x1-x2)
m = -10/(-5)
m = 2
You could also use the formula
m = (y2-y1)/(x2-x1)
to get the same result. All that matters is that you subtract in the same order for the x and y coordinates.
Find the slope of the line that passes through the following pair of coordinates: (15,18) (0,6)
Answer: y= (4/5)x+6
Step-by-step explanation:
(0,6) is the y intercept/b . Use y2-y1 for the slope/m. Y= Mx+b now is y=(4/5)x+6.
Find the equation of the line passing through the given points. Express the equation in standard form.
(1,-6) and (-7,2)
We want to write the equation of the line passing through these two points in standard form.
First, we are going to do this in slope intercept form and then change the form to standard form, which is Ax + By = C
We will use the equation y = mx + b, and since we are given two points on the line we are going to determine the slope of the line by determining the change in the y coordinates
m = y sub2 - y sub1 divided by the change in the X coordinates x sub2 – x sub1
We will start by determining the slope
(1, -6) the 1 is x sub 1 and the 6 is y sub 1
(-7, 2) the -7 is x sub 2 and the 2 is y sub 2
2 - (-6) = 8
-7 -1 = -8
so equation now is m = -1
So now again referring back to the slope intercept of the line we now know y = -1 + b. We still have to determine b and the y intercept, and we can do this by using one of the given points and substituting in the value for y and x, and then solve for b. Since these points are on the line, they must satisfy this equation. If we use the first coordinates, we would substitute 1 for x and -6 for y.
-6 = -1 times x, which is 1 + b
b = -5
construct the line equation y = mx + b where m = -1 & b = -5
In slope intercept form the equation would be y = -x - 5
Now we want to write this in standard form now. We have to deal with two things. The x and y terms have to be on the left side and A and B and C have to be integers.
The standard form of a linear equation is Ax + By=CA x + By = C . Move all terms containing variables to the left side of the equation.
Add x to both sides of the equation.
y + x = -5
Reorder y & x
x + y = -5
Determine the relationship
A. Parallel because the slopes are the same
B. Perpendicular because the slopes are opposite reciprocals
C. Oblique because the slopes are different
Answer:
Perpendicular because the slopes are opposite reciprocals

Calculate the average rate of change in grams per day from day 4 to day 7. Enter your answer as a decimal rounded to the tenths place.
Answer:
The average rate of change in grams from day 4 to day 7 is approximately 0.11 grams/day
Step-by-step explanation:
The table for the radioactivity in iodine-131 can be presented as follows;
[tex]{}[/tex] [tex]{}[/tex]Radioactivity in iodine-131
Grams [tex]{}[/tex] Day
1.83 [tex]{}[/tex] 1

1.30 [tex]{}[/tex] 5
1.19 [tex]{}[/tex] 6
1.09 [tex]{}[/tex] 7
1.00 [tex]{}[/tex] 8
The average rate of change in grams from day 4 to day 7 is given as follows;
[tex]The \ rate \ of \ change \ from \ day \ 4 \ to \ day \ 7 = \dfrac{F(7) - F(4) }{7 - 4} = \dfrac{1.09 - 1.41 }{7 - 4} =-\dfrac{8}{75}[/tex]
The average rate of change in grams from day 4 to day 7 = -8/75 ≈ 0.11 g/day
The average rate of change in grams from day 4 to day 7 ≈ 0.11 grams/day rounded to the tenths place.
The average rate of change in grams per day from day 4 to day 7 is 0.11.
Calculation of the average rate of change:Radioactivity in iodine-131
Grams Day
1.83 1
1.68 2
1.54 3
1.41 4
1.30 5
1.19 6
1.09 7
1.00 8
Now the average rate should be
= F(7) - F(4) \ 7 - 4
= 1.09-1.41 \3
= -8\75
= 0.11
hence, The average rate of change in grams per day from day 4 to day 7 is 0.11.
