Part A
Which line best fits the data, l, m, or n? Why?
Part B
In the equation of a line, y = mx + b, what does b stand for? What is the value of b for the line of best fit?
Part C
In the equation of a line, y = mx + b , what does m stand for? What is the value of m for the line of best fit?
Part D
Now that you know m and b, what is the equation of the line of best fit?

Answers

Answer 1

Answer:

Part A:

Most of the data points are above line m. All of the data points are below line n. The data points are evenly distributed on either side of line l. Therefore, line l is the line of best fit for the data.

Part B:

For the line of best fit, the y-intercept is approximately 10 and the slope is approximately 2 .

Part C:

Y= 2x+10

Step-by-step explanation:

Part A:

Part B:

To find the y-intercept of a line, identify where the line intersects the y-axis. Because the line of best fit is line l, the y-intercept is 10.

To find the slope, choose two points on line l, such as (10,30) and (30,70):

Part C:

To get the equation of the line, substitute the y-intercept, 10, for b and the slope, 2, for m.

In a class of students, the following data table summarizes how many students have a cat or a dog. What is the probability that a student has a cat given that they do not have a dog? ( NO LINKS )

Answers

Given:

Number of students who has a cat and a dog = 5

Number of students who has a cat but do not have a dog = 11

Number of students who has a dog but do not have a cat = 3

Number of students who neither have a cat nor a dog = 2

To find:

The probability that a student has a cat given that they do not have a dog.

Solution:

Let the following events:

A = Student has a cat

B = Do not have a dog

Total number of outcomes is:

[tex]5+3+11+2=21[/tex]

The probability that a student has a cat but do not have a dog is:

[tex]P(A\cap B)=\dfrac{11}{21}[/tex]

The probability that a student do not have a dog is:

[tex]P(B)=\dfrac{11+2}{21}[/tex]

[tex]P(B)=\dfrac{13}{21}[/tex]

The conditional probability is:

[tex]P\left(\dfrac{A}{B}\right)=\dfrac{P(A\cap B)}{P(B)}[/tex]

[tex]P\left(\dfrac{A}{B}\right)=\dfrac{\dfrac{11}{21}}{\dfrac{13}{21}}[/tex]

[tex]P\left(\dfrac{A}{B}\right)=\dfrac{11}{13}[/tex]

Therefore, the probability that a student has a cat given that they do not have a dog is [tex]\dfrac{11}{13}[/tex].

Jean wants to invest a gift of $4,250 in the stock market. A broker suggests two companies, Solar Solutions (SOLR) and Frontline Medical (FLMD). He provides the probabilities for an annual return on $4,250 based on their historical gains: SOLR: 50% chance of $1,000 gain, 35% chance of $200 gain, 15% chance of $600 loss FLMD: 80% chance of $750 gain, 20% chance of $100 loss Which is the best analysis of these investments?

Answers

Answer:

the answer is the question with $580 in it please correct me if im wrong

Step-by-step explanation:

Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.

How to calculate the expected return?

The expected return on SOLR is calculated by multiplying the probability of each outcome by the amount of the gain or loss, and then adding these results:

50% chance of $1,000 gain: 0.5 x $1,000 = $500

35% chance of $200 gain: 0.35 x $200 = $70

15% chance of $600 loss: 0.15 x -$600 = -$90

Therefore, the expected return on SOLR is $500 + $70 - $90 = $480.

The expected return on FLMD is calculated in the same way:

80% chance of $750 gain: 0.8 x $750 = $600

20% chance of $100 loss: 0.2 x -$100 = -$20

Therefore, the expected return on FLMD is $600 - $20 = $580.

Since the expected return on FLMD is higher than the expected return on SOLR, FLMD is the better investment.

The expected return on FLMD is $580, which means that Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.

f(x) = x°-9x
g(x) = x2 - 2x-3
Which of the following expressions is equivalent to f(x)/g(x), for x > 3

Answers

F(x)=x^3-9x
and
g(x)=x^2-2x-3

so you just need to divide f(x) by g(x)

Therefore:

f(x)/g(x) = (x^3-9x) / (x^2-2x-3)

and of course you need to factor these two function to see if some factor would cancel another

x^3-9x = x(x^2-9)=x(x-3)(x+3)
and
x^2-2x-3 = (x-3)(x+1)

Step-by-step explanation:

The angles are supplementary

(2x + 40) + (3x - 85) = 180

Combine like terms

5x - 45 = 180

Add 45 to both sides

5x = 225

Divide both sides by 5

have x 50 notes and y N100 notes. There
are eight notes altogether and their total
value is N550. How many of each note do
I have

Answers

Answer:

Step-by-step explanation:

You need to use simultaneous equations to solve this problem since there are 2 variables.

1. 50x + 100y = 550 (value of the notes x the number of each note)

2. x + y = 8 (the number of each note added).

3. Multiply the second equation by 50 so that it the x variables are the same in both equations. Thus, 50x + 50y = 400.

4. Subtract 50x + 50y = 400 from 50x + 100y = 550.

5. The subtraction results in 50y = 150.

6. Divide by 50. y = 3, so x must equal 5.
