Calculate The Residuals For The Scatter Plot (image Provided)

Answers

Answer 1

From the given graph, and using the scatter plot function of a graphing calculator, the residuals are;

-0.08693, -0.019376, -0.518, -0.183, -0.083, 0.135, 0.318, and 0.578

Which method can be used to find the residuals?

From the diagram, the given points are;

(14, 4), (15, 4), (16.5, 3.5), (18, 4), (18, 3.9), (19.5, 3.85), (20, 4), (26.8, 3.8)

Utilizing a graphing calculator, using the scatter plot function we have the following predicted values;

Best fit line; y = 5.032 - 0.0676•x

Residuals = Actual - Predicted from equation

The residuals are;

y1 = 4 - 4.08693 = -0.08693

y2 = 4 - 4.019376 = -0.019376

y3 = 3.5 - 3.918 = -0.518

y4 = 4 - 3.817 = -0.183

y5 = 3.9 - 3.817 = -0.083

y6 = 3.85 - 3.715 = 0.135

y7 = 4 - 3.682 = 0.318

y8 = 3.8 - 3.222 = 0.578

The residuals are therefore;

The residuals are;

-0.08693, -0.019376, -0.518, -0.183, -0.083, 0.135, 0.318, and 0.578

what does 160=7x+6 equal to?

Answers

Answer:

x=22

Step-by-step explanation:

7x+6=160.

Lets start by moving 6 over to the other side. We can do this by subtracting 6 from both sides of the equation.

7x+6-6=160-6

7x=154

Now, let's isolate x by getting rid of the 7. The 7 is being multiplied with x, so to get rid of it we have to divide both sides by 7.

7x/7 = 154/7

x=22

Look Below :

Step-by-step explanation:

160 - 6 = 7x

154 = 7x

Answers

The points on the graph of the inverse variation are of the form:

(x, 8/x)

Which ordered pairs are on the graph of the function?

An inverse variation function is written as:

y = k/x.

Here we know that k = 8.

y = 8/x

Then the points (x, y) on the graph of the function are of the form:

(x, 8/x).

So evaluating in different values of x, we can get different points on the graph:

if x = 1, the point is (1, 8)if x = 2, the point is (2, 4)if x = 3, the point is (3, 8/3)if x = 4, the point is (4, 2)

The sum of two numbers is 8 and sum of their reciprocal is 8/15. Find the numbers.​

Answers

x + y = 8
x = 8 - y
And,
1/x + 1/y = 8/15
y + x/xy = 8/15
8/xy = 8/15
xy = 15
( 8 - y)y = 15
8y - y^2 = 15
y^2 - 8y + 15 = 0
y^2 - 3y - 5y + 15 = 0
y(y - 3) - 5( y - 3) = 0
(y - 3) (y - 5) = 0
y = 3 & x = 5
Thus, the two numbers are 3 and 5.

Answer:

The 2 numbers are 3 and 5.

Step-by-step explanation:

x + y = 8

1/x + 1/y = 8/15

From first equation  y = 8 - x so

1/x + 1 / (8-x) = 8/15

Multiply through by the LCM 15x(8-x):-

15(8 - x) + 15x =  8x(8-x)

120 - 15x + 15x = 64x - 8x^2

8x^2 - 64x + 120 = 0

x^2 - 8x + 15 = 0

(x - 3)(x - 5) = 0

x = 3 or  5

so y = 8-3 = 5 or 3.

Step-by-step explanation:

2. Given the equation of a line, y = 1/5x, the slope is:

Answers

Answer:

1/5

Step-by-step explanation:

The slope-intercept form looks like [tex]y=mx+b[/tex] where b is the y-intercept and m is the slope. m is the slope because if you increase x by 1, the value y increases by m, and if you increase x by 1 again, the y-value will increase by the value of m, because it's being multiplied. b is the y-intercept since the y-intercept is when x=0 so mx will become m(0) which is just 0 leaving b by it self. In this case you have y=1/5x so if you were to start with 0 as x the value of y is 0. Now increase it by 1 so x becomes 1, the value of y becomes 1/5x, now increase it by 1 again so x becomes 2, the value of y is 2/5x, so as you can see the function is just increasing by 1/5 so that's the slope, so essentially whatever the coefficient of x is (the number in front of the variable x), is the slope

Solution:  In order to determine the slope of the line we need to see how the slope-intercept form compares to this expressions.  The slope-intercept form is y = mx + b where m is the slope and b is the y-intercept.  In this case we have no y-intercept therefore we do not have a b.

Answer:

P = 55°

K = 27°

Step-by-step explanation:

55° + 98° + c = 180°

153° + c = 180°

c = 27°

since C is opposite K, K = 27°

Since 55° is opposite P, P = 55°

We can check this by adding up the values of P, K, and 98

27°+55°+98° = 180°

32 less than 3/7 of a number is 11/35 of that number. Find the number.

Answers

Answer is x=280
Step by step
We know 32 less than is subtraction -32
We know 3/7 of a number is 3/7x
We know “is” is equal =
We know 11/35 of a number is 11/35x
So
3/7x - 32= 11/35x

Now solve by first by combining like terms
Change the denominator of 3/7 to match the other fraction so we can combine. 7x5=35 so we do the same to the numerator, 3x5.
3. 15
____. _____
7. 35

3/7x -32 = 11/35x
15/35x - 32 = 11/35x
Subtract 15/35x from both sides to combine like terms
-32 = -4/35x
Now divide both sides by -4/35 to solve for x
To divide a fraction flip it and multiply
( -35/4 )(-32)
X= 280

You can check your work by substituting your number for x into your equation

3/7 (280) -32 = 11/35 (280)
120 - 32 = 88
88 = 88

Answer:

Step-by-step explanation:

Let "a number" be x.

"3/7 of a number" means (3/7)x

"32 less" means - 32

Thus, "32 less than 3/7 of a number" means (3/7)x -32

"is 11/35 of that number" means = (11/35)x

Put these together and we get:

(3/7)x -32 = (11/35)x

(3/7)x - (11/35)x = 32   Rearrang to get the x on one side

We need to change "(3/7)x - (11/35)" so that the two terms have a common denominator.

If we multiply the first term by (5/5) [which is equal to 1], we get:  

(5/5)(3/7)x or

(15/35)x

We can now write:

(15/35)x - (11/35)x = 32

(4/35)x = 32

Multiply both sides by (35/4)

(35/4)(4/35)x = (35/4)(32)

x = (35)(8)

x = 280

A pencil cost $1.20 and a pen cost $2.90. Jasmiah bought an equal number of such pencils and pens. She spent $32.30 more on the pens than on the pencils. How many pencils and pens did she buy altogether?

Answers

Answer:

38

Step-by-step explanation:

Let x be the number of pencils bought.

Let y be the number of pens bought.

Given information from the question:

x = y - equation 1

2.9y - 1.2x = 32.30 - equation 2

From here we can use the substitution method in solving simultaneous equations to find x and y. We will substitute equation 1 into equation 2.

2.9y - 1.2y = 32.30

1.7y = 32.30

y = [tex]\frac{32.3}{1.7} \\= 19[/tex]
