Which two points would a line of fit go through to best fit the data?
(3, 6) and (7, 3)
(3, 7) and (9, 1)
(1, 9) and (5, 7)
(1, 7) and (2, 5)
Answer:
(a) (3, 6) and (7, 3)
Step-by-step explanation:
You want the two points that best describe a line of best fit through the data shown on the given graph.
Line of best fitA calculator finds the slope of the line of best fit to be about -0.74. The pair of points that best matches that is ...
(3, 6) and (7, 3) . . . . choice A
The line through these points has a slope of -0.75 and is very close to the best-fit line. The attachment shows how the various point pairs relate to the computed line. The answer choice points are the larger red dots.
__
Additional comment
The slope of the line of best fit is the ratio of the covariance of x and y to the variance of x:
m = cov(x, y)/var(x) = -7.744/10.455 ≈ -0.741

theta is a right angled triangle tan theta=24/43) work out the value of theta give your answer to 1 decimal place
Answer:
We know that tan(theta) = opposite/hypotenuse = 24/43.Using inverse tangent, we can find the angle theta:theta = tan^(-1)(24/43)Using a calculator, we can find:theta ≈ 29.6 degrees (rounded to 1 decimal place)Therefore, the value of theta to 1 decimal place is approximately 29.6 degrees.
Step-by-step explanation:
The value of theta in a right angle triangle for which tan(theta) = 24/43 can be found using the inverse tangent function, also known as arctan. When evaluated, theta equals approximately 29.4 degrees.
Explanation:In trigonometry, the tangent of an angle in a right angle triangle is the ratio of the side opposite to the angle to the side adjacent to the angle. Here, tan(theta) = 24/43, which means the ratio of the opposite side to the adjacent side is 24/43. To find the angle 'theta', you will need to use the inverse tangent function, commonly known as arctan or tan^-1.
In this case, theta = arctan(24/43). Use a calculator and ensure it's set to give the answer in degrees, not radians. The answer would be approximately 29.4 degrees to 1 decimal place.

Step-by-step explanation:
With the way the equations are set up, substation is faster.
Just substitute -1/2x + 8 for the y in the first equation.
3x + 4(-1/2x + 8) = 36
And then you can just solve the equation. You would get x = 4.

How many pounds of candy that sells for $1.25 per Ib must be mixed with candy that sells for $0.75 per lb to obtain 20 lb of a mixture that should sell for $1.20 per lb?
Let x be the number of pounds of candy that sells for $1.25 per lb that we need to mix, and let y be the number of pounds of candy that sells for $0.75 per lb. We can set up a system of equations to represent the problem:
x + y = 20 (we need a total of 20 pounds of candy in the mixture)
1.25x + 0.75y = 1.20(20) (the value of the mixture should be $1.20 per lb)
Simplifying the second equation, we get:
1.25x + 0.75y = 24
Multiplying the first equation by 0.75 and subtracting it from the second equation, we can eliminate y:
1.25x + 0.75y = 24
0.75x + 0.75y = 15
0.5x = 9
Dividing both sides by 0.5, we get:
x = 18
Therefore, we need 18 pounds of candy that sells for $1.25 per lb and 2 pounds of candy that sells for $0.75 per lb to make a 20-pound mixture that sells for $1.20 per lb.

Answer: $88
Step-by-step explanation:
1. Plug in the given data into the formula.
p = 80
r = 0.1 (represents 10%)
t = 1 year
2. Solve for i based on the formula's values
i = (80)(0.1)(1) = 8
Interest earned is $8 but THIS IS NOT THE FINAL ANSWER!
3. Add i (interest) to p (starting amount)
Elena started with $80, so the interest of $8 is added for a final answer of $88 after one year.

The graph of y = f(x) is shown in the attached image.
For each point (a,b) that is on the graph of y = f(x), the point (2a +1, 3b) is plotted, forming the graph of another function y = g(x). As an example, the point (0,2) lies on the graph of y = f(x), so the point (2*0 + 1, 3*2) = (1, 6) lies on the graph of y = g(x).
I need help expressing g(x) in terms of x and describing the transformations that can be applied to the graph of y = f(x) to obtain the graph of y = g(x). I would like an explanation.
The calculated expression of function g(x) in terms of x is g(x) = 3f((x-1)/2)
Expressing the function g(x) in form of xTo express g(x) in terms of x, we need to use the relationship given between the points on the graph of y=f(x) and the corresponding points on the graph of y=g(x).
Specifically, if a point (a,b) is on the graph of y=f(x), then the point (2a+1,3b) is on the graph of y=g(x).
Using this relationship, we can write:
g(x) = 3f((x-1)/2)

3.14 otherwise known as pi
lets multiply pi by radius^2
3.14×3^2= 28.26 divide it by 2 because circle is cut in half 28.26/2= 14.13

Answer: 128
Step-by-step explanation:

Use PEMDAS1.Do the parentheses-(These are parentheses) first
When the number it touching another number like this, you need to multiply them together
12x6=72
72+14x2x2
2. Then do exponents, but we don't have any so next to multiplying
2x2=4
72+14x4
14x4=56
3. Now we divide, but we don't have to divide anything so now we add
72+56=128
4. There is no subtraction in the problem, so now we are done and the total is 128

What is the difference between factors of a number and multiples of a number?
Use the number 25 as an example.
Answer:
Factors are like numbers that are multiplied together to get that number
Using 25:
The factors of 25 are 1,5,25
1*25 = 25 and 5*5 = 25, so they are the factors of 25
Multiples are the products of the specified number and another number
Using 25:
Some of the multiples of 25 are 25, 50, 75, 100 and so on
25*1 = 25, 25*2 = 50, 25*3 = 75, 25*4 = 100, so they are the multiples of 25

Answer:
Step-by-step explanation:
The sum of the interior angles of a triangle is 180 degrees. Therefore, we can set up an equation using the measures of the angles in triangle ABC:
ZABD + CBD + ABC = 180
Substituting in the given measures, we get:
(0.12x + 64) + (0.13x + 28) + ABC = 180
Simplifying and solving for x, we get:
0.25x + 92 + ABC = 180
ABC = 180 - 0.25x - 92
ABC = 88 - 0.25x
We know that the measure of angle ABC is 0.11x + 12. Substituting this into the equation for ABC, we get:
0.11x + 12 = 88 - 0.25x
Solving for x, we get:
0.36x = 76
x = 211.11
Therefore, the value of x is approximately 211.11.
Answer:
x = 352
Step-by-step explanation:
From the given Linear Pair, we can observe that ∠ABD and ∠CBD form a Straight Angle which is 180°.
∠ABD = 0.12x + 64°
∠CBD = 0.13x + 28°
Now we can understand that ∠ABD + ∠CBD = ∠ABC (Linear Pair)
∠ABC = 180°
So, ∠ABD + ∠CBD = 180°
(0.12x + 64°) + (0.13x + 28°) = 180°
(0.12x + 0.13x) + (64° + 28°) = 180° (Distribution Property)
0.25x + 92° = 180°
0.25x = 180° - 92°
0.25x = 88°
x = 88/0.25
x = 352
Hope my answer helps you ✌️
