Step-by-step explanation:
The question is incomplete as the required graph is not attached. The general explanation is as follows:
To calculate the slope of a line, we select two points on the line.
Assume, the points are:
[tex](x_1,y_1) = (-1,0)[/tex]
[tex](x_2,y_2) = (0,-4)[/tex]
The slope will be:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{-4-0}{0--1}[/tex]
[tex]m = \frac{-4}{1}[/tex]
[tex]m = -4[/tex]
For each of the options, the slope is calculated from the following representation
[tex]y = mx + b[/tex]
Where
[tex]m \to[/tex] slope i.e. the coefficient of c
By comparison, we have:
[tex]A.\ m =4[/tex]
[tex]B.\ m = 7[/tex]
[tex]C.\ m = -4[/tex]
[tex]D.\ m = -4[/tex]
So: (C) and (D) have the same coefficients as the assumed function

Which is most likely the correlation coefficient for the
set of data shown?
Answer:
0.872
Step-by-step explanation:
The regression fits the data well leavubgbiut just one of the points, this shows there is a strong relationship between the plotted variables. Also, we have to look at the direction of the regression line which will give us an idea of the slope, hence the type of correlation between the two variables (either positive or negative relationship). In this case the slope is positive and hence the correlation Coefficient will be positive as well. Hence we can say there is a strong positive relationship between the variable. The only option which depicts this association is 0.872
Let A be an m x n matrix and let b be a vector in RM. Three of the following four statements are all equivalent to each other. Choose the one statement that is not equivalent to the other three.
(a) The reduced row echelon form of Ab] has no zero row.
(b) The system Ax = b has a solution.
(c) b can be expressed as a linear combination of the columns of A.
(d) b is in the span of the columns of A.
Answer:
A.
Step-by-step explanation:
From the given information:
If A = m × n matrix
where;
b is a vector in [tex]R^m[/tex]
Then; the statement that doesn't fit and is not related to the other three from the given options is Option A.
This is because the statement in Option A appears to be inconsistent. For the model Ax=b to have a solution, A must be non-singular and b must be in A's column space.
Option c and d are equivalent, also option b and c are equivalent.

Write the equation of the line that passes through the points (5, -1) and
(2, -1). Put your answer in fully reduced point-slope form, unless it is a
vertical or horizontal line.
Answer:
y = -1
Step-by-step explanation:
First, you find the slope by using the slope formula and get 0. Now, choose one coordinate and plug it into the equation y = mx + b along with the slope. If you chose the first coordinate, the equation would be -1 = (0)(5) + b. After solving for b (the y-intercept) you would get -1. Lastly, you rewrite the equation as y = -1.

Write the equation of the circle that is centered at (- 13, - 2) and has a diameter of 24^ *
Step-by-step explanation:
Given :-
Centre = (-13,-2) Diameter = 24And we need to find out the equation of the circle. Since the diameter is 24 u therefore it's radius will be 12 u . Now we can use the Standard equation of circle to find out the equation .
Standard equation of circle :-
[tex]\implies (x-h)^2+(y-k)^2 = r^2 [/tex]
Where (h,k) is centre and r is radius.[tex]\implies (x-(-13))^2+(y-(-2))^2 = 12^2 \\\\\implies ( x+13)^2+(y+2)^2=144 \\\\\implies x^2+169+26x+y^2+4+4y=144\\\\\implies x^2+y^2+26x+4y+ 29 =0[/tex]

Answer: -52.2936778905
Step-by-step explanation:
Write the formula for the parabola that has x- intercepts (3,0) and (8,0), and y- intercept (0,−2)
Answer:
(-1/12)(x-3)(x-8)
or
[tex]-\frac{x^2-11x+24}{12}[/tex]
Step-by-step explanation:
If something has x intercepts of (3,0) and (8,0) we can write the following
y=(x-3)(x-8)
To make the y intercept (0,-2) we will mulitply this by some constant, a
y=a(x-3)(x-8)
to solve for a set y= -2 and x=0
a(0-3)(0-8)= -2
a(-3)(-8)= -2
24a= -2
a= -1/12
Which means our final equation is
(-1/12)(x-3)(x-8)
which in standard form is equal to
[tex]-\frac{x^2-11x+24}{12}[/tex]
The mean temperature for the first 4 days in January was 1°C.
The mean temperature for the first 5 days in January was 3°C.
What was the temperature on the 5th day?
Answer:
Step-by-step explanation:
mean is average, so if we label the first through fifth days of january a-e we can solve it.
So average of the first four is (a+b+c+d)/4 = 1 and the first five is (a+b+c+d+e)/5 = 2. Since it's easy, let's get rid of the fraction in both.
(a+b+c+d)/4 = 1 and (a+b+c+d+e)/5 = 2
a+b+c+d = 4 and a+b+c+d+e = 10
Now, we know a+b+c+d is 4, so we can replace that in the second equation
a+b+c+d+e = 10
4 + e = 10
e = 6
ad since e is the fifth day, we know the temperature of it. Let me know if something here didn't make sense

Find the measure of angle QZT.
========================================================
Explanation:
Minor arc QV is 80 degrees because it adds to minor arc VU = 100 to get 80+100 = 180. Note how angle QPU = 180, since it's a straight line and QU is a diameter of the circle.
Add up the minor arcs
TUUVVQto get: 44+100+80 = 224
This means arc TUQ is 224 degrees. Inscribed angle QZT subtends arc TUQ. Use the inscribed angle theorem to say that the inscribed angle is half of the arc it cuts off.
angle QZT = (arc TUQ)/2
angle QZT = 224/2
angle QZT = 112 degrees

Answer:

• If the values are opposites or additive inverses, add the equations.
Step-by-step explanation:
Given
[tex]12x = 48 - 8y[/tex]
[tex]10x + 8y = 38[/tex]
Required
How to solve
Options (1) and (2) are incorrect because none of the options eliminate x or y.
For option (3),
- Check for the coefficients of x and y
- If they are the same (sign and value), then subtract; otherwise add
For instance:
[tex]12x = 48 - 8y[/tex]
[tex]10x + 8y = 38[/tex]
Rewrite the second equation
[tex]12x = 48 - 8y[/tex]
[tex]10x = 38 - 8y[/tex]
The coefficient of y are the same, so we subtract;
[tex]12x - 10x = 48 - 38 -8y -(-8y)[/tex]
[tex]12x - 10x = 48 - 38 -8y +8y[/tex]
[tex]2x = 10[/tex]
[tex]x= 5[/tex]
See that y has been eliminated

A woman has eight keys on a key ring, one of which fits the door she wants to unlock. Sherandomly selects a key and tries it. If it does not unlock the door, she randomly selects anotherkey from those remaining and tries to unlock the door with it. She continues in this manner untilthe door is unlocked. Let X be the number of keys she tries before unlocking the door, countingthe key that actually worked.
Required:
Find the expected number of keys she will try before she opens the door.
Answer:
The expected number of keys she will try before she opens the door is 4.5.
Step-by-step explanation:
A woman has eight keys on a key ring, one of which fits the door she wants to unlock.
Each of them is equally as likely to be the one to work, which means that this situation is represented by an uniform distribution with lower bound [tex]a = 1[/tex] and upper bound [tex]b = 8[/tex].
Find the expected number of keys she will try before she opens the door.
The expected value of the uniform distribution is given by:
[tex]E = \frac{a + b}{2}[/tex]
Considering [tex]a = 1, b = 8[/tex], as is the case in this exercise:
[tex]E = \frac{1 + 8}{2} = 4.5[/tex]
The expected number of keys she will try before she opens the door is 4.5.

To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing calculator, but he could only see one line. Why is this? because the system of equations actually has only one solution because the system of equations actually has no solution because the graphs of the two equations overlap each other because the graph of one of the equations does not exist
Answer:
because the graphs of the two equations overlap each other
Step-by-step explanation:
Equations that have an infinite amount of solutions overlap each other when graphed.
This is because equations with an infinite amount of solutions have a similar equation so when graphed you only see one line

measure of the angle labeled?
Given:
The figure of a circle.
The measure of arc SR = 75 degrees.
Measure of angle RSQ = 95 degrees.
To find:
The measure of SQ.
Solution:
Let us consider, O be the center of the circle.
According to the central angle theorem, the measure central angle on an arc is twice of inscribed angle on the corresponding angle.
Using the central angle theorem, we get
[tex]m\angle QOR=2\times m\angle RSQ[/tex]
[tex]m\angle QOR=2\times (95^\circ)[/tex]
[tex]m\angle QOR=190^\circ[/tex]
It is the central angle on major arc QR.
We know that the measure of complete central angle is 360 degrees.
The central angle on minor arc QR is:
[tex]360^\circ -190^\circ =170^\circ[/tex]
It means the measure of arc RSQ is 170 degrees.
[tex]m(arc RS)+m(arc SQ)=m(arcRSQ)[/tex]
[tex]75^\circ+m(arc SQ)=170^\circ[/tex]
[tex]m(arc SQ)=170^\circ -75^\circ[/tex]
[tex]m(arc SQ)=95^\circ[/tex]
Therefore, the measure of arc SQ is 95 degrees.
