The line of best fit to model the data in the table is y = 5.2x – 0.4. a 2-column table with 5 rows. the first column is labeled x with entries 1, 2, 3, 4, 5. the second column is labeled y with entries 8, 13, 18, 23, 24. what is the residual for 5? –1.6 –0.6 0.6 1.6

Answers

From the line of the best fit y = 5.2x -0.4 for the considered data, the residual for x = 5 is given by: Option A: -1.6

How to find the residual value for a given input output pair?

Suppose the given input output pair be (x,y) (actual data point)

Then suppose the prediction be y' from the line of best fit for that input x.

Then the residual value will be calculated for that point as:

Residual value = Actual value - Predicted value

Residual = y - y'

Here, we're given the data as:

         x                         y

         1                          8

         2                        13

         3                        18

         4                        23

         5                        24

The line of best fit for this data is [tex]y= 5.2x -0.4[/tex]

For x = 5, the real corresponding y value is 24, and the predicted value is:

[tex]5.2(5) -0.4 = 25.6[/tex]

Thus, the residual for x=5 is: y - y' = 24 - 25.6 = -1.6

Thus, from the line of the best fit y = 5.2x -0.4 for the considered data, the residual for x = 5 is given by: Option A: -1.6

A bag contains 5 blue marbles, 2 green marbles, and 3 yellow marbles. What is the probability of choosing one green marble and then a yellow marble with replacement? 3/50 1/15 1/2 6/10

Answers

Answer:

Step-by-step explanation:

Total number of marbles = 5 + 2 + 3 = 10

Probability of choosing 1 green marble = 2/10

Probability of choosing 1 yellow marble = 3/10

Notice (and this is important) that the denominator didn't change. Why?

Because you replaced the first marble into the bag. That word replacement is critical in a problem of this nature. There is the term non replacement which means that the second draw would have a denominator of 9.

So what is the probability of P(green then yellow)?

P(green then yellow) = 3/10 * 2/10 = 6/100

Answer: P(green then yellow) = 3/50 because 6 / 100 reduces.

Which expression represents the height of the triangular base of the pyramid? five-halves startroot 2 endrootunits five-halves startroot 3 endrootunits 5 startroot 2 endrootunits 5 startroot 3 endrootunits

Answers

The expression that represents the height of the triangular base of the pyramid is given by: Option B: (5/2)√3 untis

What is Pythagoras Theorem?

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

The question is incomplete, and the upper part of the completed question is:
"The base of a solid oblique pyramid is an equilateral triangle with an edge length of 5 units. A solid oblique pyramid has an equilateral triangle base with an edge length of 5 units. "

The diagram of the base of the considered pyramid is attached below.

The perpendicular from A to BC is touching BC at C, and is bisecting it (it can be proved).

Consider the triangle ADB. It is a right angled triangle.

We need the length of AD which represents the height of the triangle ABC.

This is obtained using Pythagoras theorem as:

[tex]|AB|^2 = |AD|^2 + |DB|^2\\\\|AD|^2 = |AB|^2 - |DB|^2\\\\|AD| = \sqrt{5^2 - \left( \dfrac{5}{2}\right)^2}[/tex]

(took positive root because of |AD| being length, which is a non-negative quantity).

SImplifying it, we get:

[tex]|AD| = \sqrt{5^2 - \left( \dfrac{5}{2}\right)^2}\\\\|AD| = \sqrt{\dfrac{5^2(4-1)}{4}} = \dfrac{5\sqrt{3}}{2} = \dfrac{5}{2} \times \sqrt{3} \: \rm units[/tex]

Thus,  the expression that represents the height of the triangular base of the pyramid is given by: Option B: (5/2)√3 untis

Would the sum of the interior angles of a triangle in this type of geometry be different from those of triangle in Euclidean geometry? Explain.

Answers

Answer: Yes

Step-by-step explanation:

If a triangle was inscribed onto the surface of a sphere, the sum of its interior angles will not add up 180 degrees. This is actually a method in differential geometry to see if a surface is flat or curved; see if the angles up to 180 degrees. Now, it depends on how large the triangle is. If we were to draw a triangle on the surface of the earth with lets say a piece of chalk, the angles will appear to add up to 180 degrees. The larger amount of surface that the triangle covers, the larger deviation you will get from 180 degrees.

s/(2πh) = r

Step-by-step explanation:

You want to put the unknown value you are solving on 1 side and rest on the other side. In this case, you have to have r alone on one side.

s=2πrh

Since they are all multiplied with r, you divide them all on both sides to send them to other side.

s/(2πh) = 2πrh/ (2πh)

cancel out right side and it leaves r alone.

s/(2πh) = r

Ms. Gartland bought x number of shirts for the new members of her chorus. The cost for x number of shirt, including $3.99 shipping was $77.49 each shirt cost 12.25 there was no sales tax on this purchase. which equation could be used to find?

Answers

Answer:

12.25s + 3.99 = 77.49 would be your equation used to find the amount of shirts purchased.

When we solve the equation, we get 6 which is the quantity of shirts Gartland purchased.

Step-by-step explanation:

We know the shirts were 12.25 but we didnt know how much she pruchased leaving our shirts (s) unknown.

We added 3.99  for shipping and our total cost was 77.49

We do 12.25s + 3.99 (shipping) = 77.40 total cost

Find the sum of 150+143+136+…+(-102)+(-109) arithmetic series

Answers

Answer:

779

Step-by-step explanation:

Given Arithmetic series is: 150+143+136+…+(-102)+(-109)

Here,

First term (a) = 150

Common difference (d) = 143 - 150 = - 7

[tex]n^{th}\: term:\:a_n = -109[/tex]

The formula for [tex]n^{th}\: term[/tex] of an arithmetic series is given as:

[tex]a_n = a +(n-1)d[/tex]

Plugging the values of a, d and [tex]a_n[/tex] in the above formula, we will find the number of terms that exist from 150 to (-109)

[tex]-109 = 150+(n-1)(-7)[/tex]

[tex]\implies\: -109 -150=(n-1)(-7)[/tex]

[tex]\implies\: -259=(n-1)(-7)[/tex]

[tex]\implies\: \frac{-259}{-7}=(n-1)[/tex]

[tex]\implies\: 37=n-1[/tex]

[tex]\implies\: 37+1=n[/tex]

[tex]\implies\: n=38[/tex]

Thus, there are total 38 terms in the given Arithmetic series.

Now,

Sum of n terms of an arithmetic series is given by the formula: [tex]S_n=\frac{n}{2}(a +a_n)[/tex],

Plugging in the values, we find:

[tex]S_{38}=\frac{38}{2}[150 +(-109)][/tex]

[tex]\implies S_{38}=\frac{38}{2}[150 +(-109)][/tex]

[tex]\implies S_{38}=19[150 -109][/tex]

[tex]\implies S_{38}=19[41][/tex]

[tex]\implies S_{38}=779[/tex]
