Answer:

Runner C

Step-by-step explanation:

Tell me if I'm wrong but 100% sure I'm right

The linear regression for the best fit of the data to identify the runner that kept the most consistent pace is Runner C

The connection between the independent (x) and dependent (y) variables in the graph can be graphically represented using regression lines.

In a linear model, the terms are added rather than multiplied, divided, or provided as a non-algebraic function, as has been the case thus far in this section. Analysis of experimental, monetary, and biological data as well as complex system prediction are both possible using linear modelling.

A statistical technique used to build a linear model is called linear regression. The model explains how one or more independent variables Xi relate to a dependent variable y (also known as the response) (called the predictors). The distance between each data point and the regression line is called a residual.

Given data ,

Three runners competed in a race data were collected at each mile mark for each runner

And , If the runner ran at a constant paste the data would be linear

Now , a  linear a regression line was fitted to their data

And , In linear regression, consistent data refers to a set of data points that fall in a linear pattern with a small amount of scatter around the line of best fit. The data is said to be consistent if the residuals (the vertical distances between the observed data points and the predicted values on the line of best fit) are relatively small and do not exhibit any patterns or trends.

So , the runner C has the most consistent pace among the three runners

Hence , runner C is the best fit for the regression line

Answer: x=-6

Step-by-step explanation:

Given

2x + 8 = -4

Subtract 8 on both sides

2x + 8 - 8 = -4 - 8

2x = -12

Divide 2 on both sides

2x / 2 = -12 / 2

x = -6

NOTE: I assume the questions "solve for c" actually means "solve for x"

Step-by-step explanation:

Answer:

a) 0.45 hours

b)

P( Ron ) = 7/12

P( sue ) = 4/15

P(Ted ) = 3/20

c)  1.22 hours

Step-by-step explanation:

Ron , sue and Ted

mean values = 1, 1/2 , 1/3  hours

a) determine the expected time until only one student remains

E(x) = 9/20 = 0.45 hours

b) Probability that each student is the last student left

P( Ron ) = 7/12

P( sue ) = 4/15

P(Ted ) = 3/20

C) Time until all students are gone

= 146 / 120 =  1.22 hours

attached below is the detailed solution

This question is based on the concept of probability.Therefore, the answers are as follows:

(a) 0.45 hours

[tex]\bold{(b) \, P(Ron) = \dfrac{7}{12} ,P (Sue) = \dfrac{4}{15} ,P(Ted) = \dfrac{3}{20}\beta}[/tex]  

(c)  1.22 hours

Given:

The amount of time they will stay is exponentially distributed with means 1, 1/2, and 1/3 hours.

According to the question,

The amount of time they will stay is exponentially distributed with means 1, 1/2, and 1/3 hours.

(a) The expected time until only one student remains,

[tex]E(X) = \dfrac{9}{20} = 0.45 \,hours[/tex]

(b)  Now, find the probability they are the last student left,

[tex]P(Ron) = \dfrac{7}{12} \\P (Sue) = \dfrac{4}{15} \\P(Ted) = \dfrac{3}{20}[/tex]

(c) The expected time until all three students are gone is,

[tex]= \dfrac{146}{120} \\\\= 1.22 hours[/tex]

Therefore, the answers are as follows:

(a) 0.45 hours

[tex](b) P(Ron) = \dfrac{7}{12} ,P (Sue) = \dfrac{4}{15} ,P(Ted) = \dfrac{3}{20}\beta[/tex]

Step-by-step explanation:

1 Meter is equal to 0.001 Kilometer

1 Centimeter is equal to 0.01 Meters

The unit conversions which has the true measurements are

a) 7 cm = 0.07 m

b) 7,000 m = 7 km

In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.

The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.

A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.

Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.

Given data ,

Let the unit conversion be represented as A

Let the first measurement be p

where the value of p is

p = 7 cm

From the unit conversion , 1 m = 100 cm

So , 7 cm = 0.07 m

And , let the second measurement be q = 7,000 m

From the unit conversion , 1 km = 1,000 m

7,000 m = 7 km

Hence , the unit conversions are solved

Answer:

85

Step-by-step explanation:

Find the average of 100 and 70 which is 100 + 70 = 170/2 = 85

The value of angle m ∠ AED is,

⇒ m ∠ AED = 85 degree

We have to given that,

In the accompanying figure,

Chords AB and CD of circle O intersect at E.

And, m AD=100 and m CB=70.

Now, By given figure, we get;

⇒ m ∠ AED = (m AD + m CB) / 2

⇒ m ∠ AED = (100 + 70)/2

⇒ m ∠ AED = 170 / 2

⇒ m ∠ AED = 85 degree

Thus, The value of angle m ∠ AED is,

⇒ m ∠ AED = 85 degree

Answer:

Number 1 can form a right triangle. Numbers 2 & 3 cannot.

Step-by-step explanation:

To check if the sides are a right triangle, check if the sum of the squares of the two smaller sides equals the length of the square of the longest side. In other words, do the Pythagorean Theorem.

5² + 12² = 13²

25 + 144 = 169

169 = 169

They are equal therefore Number 1 can form a right triangle.

5² + 7² = 9²

25 + 49 = 81

74 = 81

They are not equal, therefore Number 2 can't form a right triangle.

10² + 12² = 30²

100 + 144 = 900

244 = 900

They are not equal, therefore Number 3 can't form a right triangle.
