Use absolute value to express the distance between −13 and 17 on the number line
Answer:
Step-by-step explanation:
Distance between two points a and b using the absolute value is given by
|b-a|.
Here we have a=-13
and b =17
so
Distance = | 17- (-13) |
Distance = |17 +13 |
Distance = | 30 |
Distance = 30 units
In absolute value, the distance is written as |30|
The given points:
[tex](x_1, x_2) = (-13, 17)[/tex]
To find:
the distance between -13 and 17The distance between the two points on a number line is calculated as;
[tex]Distance = \sqrt{(x_2-x_1)^2} \\\\Distance = \sqrt{(17--13)^2}\\\\Distance = \sqrt{(30)^2} \\\\Distance = + /- \ \ 30[/tex]
In absolute value, the distance is written as;
Distance = |30|

Write an equation in slope-intercept form of the line that passes through (-1,-3) and is parallel to the graph of y=4.
Answer:
The line parallel to this one and through the given point would be y = -3.
Step-by-step explanation:
In order to find a parallel line, we first have to accept that this is a horizontal line. This is because there is no x value in the equation. That means in order to make it horizontal as well, we need it to have no x value again.
Given the ordered pair, this means our new equation is y = -3

The equation of a circle is (x+7)to the second power+(y−13)to the second power=196 .
What is the center of the circle?
Enter your answer in the boxes.
Answer:
(-7,13)
Step-by-step explanation:
The equation of a circle is (x+7)to the second power+(y−13)to the second power=196
(x+7)^2 +(y-13)^2 = 196
To find the center of the circle we use the center radius form of the circle
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
where (h,k) is the verted and r is the radius of the circle
now we compare with the given equation
h= -7 and k =13
So center of the circle is (-7,13)

A photo of a painting measures
13 inches by 17 inches. The scale factor
is 1
3 . What size is the painting?
The size of the painting is [tex]\( \frac{13}{3} \) inches by \( \frac{17}{3} \)[/tex] inches.
If the photo of the painting has dimensions of 13 inches by 17 inches and the scale factor is 1/3 it means that the dimensions of the painting itself are 1/3 times the dimensions of the photo.
To find the size of the painting, we need to multiply the dimensions of the photo by the scale factor.
For the length:
[tex]\[ \text{Length of painting} = 13 \times \frac{1}{3} = \frac{13}{3} \][/tex]
For the width:
[tex]\[ \text{Width of painting} = 17 \times \frac{1}{3} = \frac{17}{3} \][/tex]

Answer:
Step-by-stPart A
Answer: 7/36
This is in fraction form
The decimal version of this number is roughly 0.1944
-----------------------------------
To get this answer, we multiply the fractions 7/9 and 2/8
The fraction 7/9 is the probability of selecting purple on the first draw. There are 7 purple out of 9 total (2+7 = 9)
The fraction 2/8 is the probability of selecting white on the second draw. This is assuming we don't put the first selection back in the bag. There are 2 white out of 8 marbles over
Multiply the fractions to get:
(7/9)*(2/8) = (7/9)*(1/4) = (7*1)/(9*4) = 7/36
============================================================
Part B
Answer in fraction form: 1/36
Answer in decimal form: 0.0278 (which is approximate)
------------------
We have 2 white out of 9 total. So the probability of getting white the first time is 2/9
After we select and don't put that first selection back, we have 1 white out of 8 left over. The probability of getting white a second time is 1/8
Multiply the fractions:
(2/9)*(1/8) = (2*1)/(9*8) = 2/72 = 1/36
============================================================
Part C
Answer: There is a greater chance to get two purple in a row
Without doing any math, you can tell that purple is more likely simply because there are more purple than white. We have 7 purple and 2 white. For any given single selection, we have a greater chance of picking purple over white.
If you want do to the math, then the probability of selecting two white marbles in a row is 1/36 = 0.0278 which was found in part B above.
The probability of selecting two purple is (7/9)*(6/8) = (7/9)*(3/4) = (7*3)/(9*4) = 21/36 = 7/12 = 0.5833
In summary,
the probability of selecting two white marbles in a row is 0.0278
the probability of selecting two purple marbles in a row is 0.5833
we see that the probability for the two purple marbles is much greater
A farmer applied different types of fertilizer to two different sections of his watermelon field. At the end of the growing season, the farmer randomly weighed 20 watermelons from each section. The table shows the mean and the mean absolute deviation (MAD) of the weights for each fertilizer.
Fertilizer Mean (lb) MAD
1 24 3
2 22 2
Calculate the means-to-MAD ratio. Can the farmer conclude that Fertilizer 1 generally produces heavier watermelons?
Select from the drop-down menus to correctly answer the question.
The farmer (can, cannot) conclude that Fertilizer 1 generally produces heavier watermelons because the distributions of weights for the two fertilizers are (identical, somewhat similar, similar, different).
What is the domain of this function
Answer:
Domain (-∞,4)U(4,∞)
Step-by-step explanation:
Inmagine functions as little machines that turn one number into another, the domain would the numbers that we can enter to the machine so we would have a real number on the output of it.
In this specific case we can use all the numbers but 4 because if we make [tex]x=4[/tex] we would have [tex]\frac{12}{4-4}=\frac{12}{0}[/tex] and this is an indeterminate form which won't be solution to the problem.
According to the explanation our domain would be all the numbers but 4 like this:
Domain (-∞,4)U(4,∞)
