Answer:
A. x = 5
Step-by-step explanation:
2 + 8x = 11x - 13 -------- subtract 2 from both sides
2 + 8x - 2 = 11x - 13 - 2
8x = 11x - 15 -------- subtract 11x from both sides
8x - 11x = 11x - 15 - 11x
-3x = -15
x = -15 / -3
x = 5

Three fair, standard six-sided dice are rolled. What is the probability that the sum of the numbers on the top faces is 18? Express your answer as a common fraction.
Explanation:
There is only one way to get a sum of 18 and that is rolling three '6's to get 6+6+6 = 18.
There are 6*6*6 = 216 different ways to roll three dice.

what is the slope of a line that passes through the points ( 3,7) and(12,7)?
Answer:
The slope is 0.
Step-by-step explanation:
To find the slope, we can do (7 - 7) / (12 - 3) = 0 / 9 = 0. This makes sense because if we look at the points, they both have the same y-coordinate, so we know that as x increases / decreases, y never changes. Because y never changes, the slope is 0.
Answer:
m=0
Step-by-step explanation:
To find slope, it is y2-y1/x2-x1
Therefore, x1=3, x2=12, y1=7 and y2=8
Plugging those variables in,
(7-7)/(12-3)=
7-7=0
12-3=9
0/9=0
Therefore, slope of the line that passes through points (3,7) and (12,7) is 0

The graph of a linear equation is a straight line.
The graph has a positive slope and it passes through the origin
The given parameters are:
[tex]\mathbf{m =\frac 23}[/tex]
[tex]\mathbf{(x,y)= (0,0)}[/tex]
A linear equation is represented as:
[tex]\mathbf{y = mx + b}[/tex]
[tex]\mathbf{m =\frac 23}[/tex]
So, we have:
[tex]\mathbf{y = \frac 23 x + b}[/tex]
[tex]\mathbf{(x,y)= (0,0)}[/tex] represents the y-intercept (i.e. b = 0).
So, we have:
[tex]\mathbf{y = \frac 23 x + 0}[/tex]
[tex]\mathbf{y = \frac 23 x}[/tex]
See attachment for the graph of [tex]\mathbf{y = \frac 23 x}[/tex]

Kendrick is using a compass and straightedge to copy angle M the figure shows the portion of the construction that he has already completed where should Kendrick place the center of the compass to do the next step of the construction
Answer:
The next step of the construction is;
Place the compass at point N and adjust the width to the point where the arc crosses the other side leg of the angle
Step-by-step explanation:
The steps to copy an angle are;
1) Mark the point C of the vertex of the new angle
2) Draw a ray from C in the desired direction
3) With the compass placed at M of the original angle, draw an arc that crosses both sides of the original angle. Mark the crossing points N and O
4) With the same compass width from the arc drawn in the above step, draw a similar arc that crosses the ray from C at point D
5) Place the compass at point N and adjust the width to point O, the point where the arc crosses the other side of the angle
6) While the adjusted compass width is held to remain the same, place the compass at point D and draw an arc to cross the previous arc drawn from C and label the intersection point E
7) With the straight edge, draw a ray FC that passes through E to point C to complete the copied angle.

A group of 4 friends likes to golf together, and each friend keeps track of her all-time lowest score in a single round. Their low scores are all between 90 and 100, except for Angie, whose low score is 80. Angie then golfs a great round and has a new low score of 75. How will decreasing Angie's low score affect the mean and median?
Answer: Mean get decreased and median remains same.
Step-by-step explanation:
Given: The low scores of all 4 friends are all between 90 and 100, except for Angie, whose low score is 80.
i.e. Angie is an outlier.
[An outlier is an extreme value which lies far from the other data values.]
Angie then golfs a great round and has a new low score of 75.
i.e. more lower value.
Since Mean gets effected by an outlier but median remains same.
Here, value of new outlier(75) is less than the previous one (80), so mean score will get decreased, where as median (middle most value in ordered data) remains the same.
If sets A and B have the same number of terms, is the standard deviation of set A greater than the standard deviation of set B? 1.The range of set A is greater than the range of set B. 2. Sets A and B are both evenly spaced sets.
Step-by-step explanation:
(1) The range of set A is greater than the range of set B.
This statement gives only the range which means only outermost values but what about the other values. For example-11,0,0,0,11 and -10,-10,0,10,10
Clearly, Former one has higher range but lower standard deviation.
(2) Sets A and B are both evenly spaced sets.
Evenly spaced is fine. However, we don't know the spacing since that is required to know the deviation.
For, example, sets A{2,4,6,8,10} and B {1,2,3,4,5} so in this case SD of A> SD of B. Or, we can have B{2,4,6,8,10} and A{1,2,3,4,5} so in this case SD of B> SD of A.

Find the value of z. A. 40 B. 80 C. 56 D. 62
Answer:
A
Step-by-step explanation:
The secant- tangent angle 50° is half the difference of the measures of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex](210 - x) = 50 ( multiply both sides by 2 )
210 - x = 100 ( subtract 210 from both sides )
- x = - 110 ( multiply both sides by - 1 )
x = 110°
The sum of the 3 arcs on the circle = 360°
210 + x + z = 360
210 + 110 + z = 360
320 + z = 360 ( subtract 320 from both sides )
z = 40°

Which number is greater -4 or 8
Answer:
8
Step-by-step explanation:
think about this: which number has the bigger distance from 0 on a number line.
-4 -3 -2 -1 0 1 2 3 4 5 6 7 8
You can see the distance between -4 and 8. Because 8 is eight spaces away from zero, and -4 is 4 spaces away from zero, we can see that 8 is bigger
The 8 is greater than -4. The difference between the two numbers is 12, and 8 is a positive number, while -4 is a negative number, solidifying that 8 is the larger value.
To compare the numbers -4 and 8, we can use the number line or basic numerical comparison. On the number line, -4 is to the left of 8, indicating that 8 is greater. Additionally, we can verify this by subtracting -4 from 8, which gives us 12 (8 - (-4) = 12). Since 12 is positive, 8 is indeed greater than -4.
In numerical comparison, when a positive number is compared to a negative number, the positive number is always greater. This is because negative numbers are "less than" zero, and positive numbers are "greater than" zero.
In conclusion, 8 is greater than -4. The difference between the two numbers is 12, and 8 is a positive number, while -4 is a negative number, solidifying that 8 is the larger value.

If 1 inch on a map represents y miles, how many miles are represented by x feet on the same map?
Answer:
1 inch represents 1 mile
66330 inches represent 1 mile
Convert to feet = 5280 feet for every mile
So if the map shows y = 1 1/4 then this means 1 1/4 miles
which would make the decimal of y = 1.25
which makes x = 5280 x 1.25 = 6600
We can just convert to decimalization the ' length of y in inches' and multiply by 5280 to find our answer.
= y * x = (1 .) + additional) * 1 * 5280
Not forgetting the above decimal if under 2 inches.
Or in any measure including if over 2 inches we can use
= measure of y * 5280 = ( ) answer
If [tex]1[/tex] inch on a map represents [tex]y[/tex] miles, then the miles represented by [tex]x[/tex] feet on the same map will be [tex]12[/tex] miles.
What is map ?A map is a visual representation of an entire area or a part of an area, typically represented on a flat surface.
What is mile?Mile is a measure of length, in one mile there 1.6 kilometers.
We have,
[tex]1[/tex] inch [tex]=y[/tex] miles
Then,
[tex]x[/tex] feet will represent miles on map will be as
We know that,
[tex]1[/tex] feet [tex]=12[/tex] inch

According to question,
Miles represented by [tex]x[/tex] feet [tex]=12y[/tex] miles
Because according to the above given statement we came to know that in [tex]1[/tex] feet there are [tex]12[/tex] inches.
Hence, we can say that if [tex]1[/tex] inch on a map represents [tex]y[/tex] miles, then the miles represented by [tex]x[/tex] feet on the same map will be [tex]12[/tex] miles.
