If the data point is at (3, 10.5) and the prediction equation is y = -6.1x + 12.5, what is the value of the residual for this data point?
Answers
Given:
The data point is (3,10.5).
The prediction equation is [tex]y=-6.1x+12.5[/tex].
To find:
The value of the residual for this data point.
Step-by-step explanation:
The data point is (3,10.5). So, the actual value is 10.5 at [tex]x=3[/tex].
Prediction equation is
[tex]y=-6.1x+12.5[/tex]
Putting [tex]x=3[/tex], we get
[tex]y=-6.1(3)+12.5[/tex]
[tex]y=-18.3+12.5[/tex]
[tex]y=-5.8[/tex]
The formula for residual is:
Residual = Actual value - Expected value
[tex]Residual=10.5-(-5.8)[/tex]
[tex]Residual=10.5+5.8[/tex]
[tex]Residual=16.3[/tex]
Therefore, the residual for the given data point is 16.3.

Answer:
-6
Step-by-step explanation:
To find the slope, you do y₂ - y₁ / x₂ - x₁
y₂ - y₁ / x₂ - x₁
= -35 - 11 / 5 - 1
= -24 / 4
= -6
The slope is -6
Answer:
-6
Step-by-step explanation:
Hi,
To find the slope when given a table, just pick two points, subtract the y values, and then divide them by the x values after you subtract them as well. Here's what I mean...
Let's use 1, -11 and 5, -35
So...
-35 - (-11)
This is the change in y. -35 - (-11) is the same thing as -35 + 11 (subtracting negative switches to adding it)
You get -24
Now, the change in x.
5 - 1 = 4
So, -24/4 and you get the slope of : -6

6*(61^2) and 61^3
Step-by-step explanation:
If the squares have a side length of 61 (assuming this is a cube) our surface area is 6*(61^2) because each side is a square and there are six sides.
As for the volume, we have 61^3.

What is Unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
for second, 30*0.9=27
for third, 27*0.9 = 24.3
Similarly for the fifth computer,
=21.87*0.9
=19.68 minutes
Total time taken,
=30+ 27 +24.3+21.87+19.68
=122.553
=123 minutes.

3. Find the measure of arc JK.
Hint - arc LK is a semi-circle!
Find JK
A) 90
B) 116
C) 128
D) 130
Answers
Answer:
Option C
Step-by-step explanation:
We will analyze the figure and note down the properties given in the figure,
1). LK is a diameter so this line (chord) divides the circle into two arcs measuring 180°.
m(arc LJK) = m(arc LK) = 180°
2). m(∠JKL) = 28°
Therefore, by the property inscribed angle and intercepted arcs,
Intercepted arc (JL) = 2 × (Inscribed angle JKL)
m(arc JL) = 2(26°)
= 52°
Now we will use these two points to get the measure of arc JK.
m(arc JK) + m(arc LK) + m(arc JL) = 360°
m(arc JK) + 180° + 52° = 360°
m(arc JK) = 360° - 232°
= 128°
Option C will be the correct option.
Which of the following points is not an ordered pair for the function
ƒ(x ) =5/2 x + 6?
4, 16)
(2, 7)
(-2, 1)
Answers
Answer:
2,7
Step-by-step explanation:
To solve this type of problem you simply plug the left number or x value in the ordered pair into the function and then see if it equals the right or y value. So we would plug 4 in for x and get 16, you then do the same thing for the other two pairs and find out that when you plug 2 into the equation, it does not equal 7
