Two students have examined the scatter plot shown and have created a line of best fit for the data. Student A believes that the line of best fit for the data is y=−2x+24, while Student B believes that the line of best fit for the data is y=1.5x+23. Determine which student created a better line of best fit given the data in the graph. Justify your answer using mathematics.

Answers

Answer 1

Answer:

Is student B because student B data has -2 which is facing the same way the scatter plot is while student A is facing the left while the scatter plot is on the right.

If you don't understand go to desmos graphing calculator and enter y=−2x+24 and y=1.5x+23.

What value represents the upper quartile of the box plot shown?

Answers

Answer:

33

Step-by-step explanation:

The median is 26 and the lower quartile is 19

The upper quartile is 30. If you look at the box, the first part of the box (left side) is the lower quartile, and the right side is the upper quartile. Therefore the answer is 30.

1992?

a. Substitute 92 for x in the equation.

b. Substitute 92 for y in the equation.

c. Substitute 22 for x in the equation.

d. Substitute 22 for y in the equation.

Answers

Answer:

c. Substitute 22 for x in the equation.

Step-by-step explanation:

The scatter plot of this question is missing, so i have attached it.

The slope equation of this is written as;

y = mx + b

Where;

y is the values in the y-axis

x is the values in the x-axis

b is the intercept on the x-axis

Now, from the scatter plot of the trend line, we can see that the values in the x-axis represent the number of years after 1970 while the y-axis shows us the price of gas per gallon for each corresponding year.

Now, we want to use the trend line equation be used to predict the cost of gas per gallon in the year 1992.

Year 1992 means 22 years after 1992. Since we have our y-intercept from the scatter plot to be 0.25, then to find the cost of gas per gallon in the year 1992, we will just plug in 22 for x and 0.25 for b into the slope line equation.

Which of the following represents a "rule of thumb" for how much
student loan debt you should be willing to incur to pay for college?

Answers

Answer:

Rule of thumb is;

Your cumulative total student loans taken as at the time you are graduating should be less than your proposed annual starting salary.

Step-by-step explanation:

When calculating the loan a college student can afford, a rule of thumb comes in very handy which is that:

Your cumulative total student loans taken as at the time you are graduating should be less than your proposed annual starting salary.

This is because If your total student loan debt is less than your proposed annual income, it means all things being equal, you would be able to pay back the loan in about 10 years or less. However, if the loan debt exceeds your proposed income, it means you are likely to going to struggle and find it very difficult to repay your loan.

Given the sequence, 26, 13, 6.5, ..... find a) the 10th term and b) the sum of the first 18 terms

Answers

Answer:

a) 10th term is 0.051

b) The sum of first 18 terms of given sequence is 51.48

Step-by-step explanation:

We are given the sequence 26, 13, 6.5, ..... we need to find

a) 10th term

b) Sum of first 18 terms

Before solving we need to determine if the sequence is arithmetic or geometric

The sequence is arithmetic if common difference d is same.

The sequence is geometric if common ratio r is same.

Finding common difference d: 13-26 = -13, 6.5-13= -6.5

As common difference is not same so, the sequence is not arithmetic.

Finding common ratio r : 13/26 =0.5, 6.5/13= 0.5

As common ratio is same so, the sequence is geometric.

a) Finding common difference: 13-26 = -13, 6.5-13= -6.5

As common difference is not same so, the sequence is not arithmetic.

a) 10th term

The formula to find 10th term is: [tex]a_n=a_1r^{n-1}[/tex]

We have a₁=26 and r = 0.5 n=10

[tex]a_n=a_1r^{n-1}\\a_{10}=26(0.5)^{10-1}\\a_{10}=26(0.5)^{9}\\a_{10}=0.051[/tex]

So, 10th term is 0.051

b) Sum of first 18 terms

The formula to find sum of geometric series is: [tex]S_n=\frac{a(1-r^n)}{1-r}[/tex]

where a= 1st term, r = common ratio and n= number of terms

In the given sequence we have

a=26, r=0.5 and n=18

Finding sum of first 18 terms

[tex]S_n=\frac{a(1-r^n)}{1-r}\\S_{18}=\frac{26(1-(0.5)^{18}}{1-0.5}\\S_{18}=\frac{26(0.99)}{0.5}\\S_{18}=\frac{25.74}{0.5}\\S_{18}=51.48[/tex]

So, sum of first 18 terms of given sequence is 51.48

Step-by-step explanation:

1. Add similar elements: 4x+27x=31x

2. Multiply 13 times 2 to get 26

3. Once again add the similar elements: 31x+26x=57x

4.  Expand!!: Originally (4x+1) take away the Parentheses!!

5. 57x+6=4x+1

6. Subtract 6 from both sides: 57x+6-6=4x+1-6

7.  Simplify: 57x=4x-5

8. Subtract 4x from both sides: 57x-4x=4x-5-4x

9. Simplify: 53x=-5

10. Divide both sides by 53: 53x/53= -5/53

11. x= -5/53

The product of (2 + 7i) (2 - 7i) in the form of a + bi is 53 + 0i.

What is an imaginary number?

An imaginary number is denoted by i.

The value of i is √-1.

i² = √-1² = -1

We have,

(2 + 7i) (2 - 7i)

We need to write in the form of a + bi.

a + bi

a = real number

b = imaginary part

(2 + 7i) (2 - 7i)

Remove the brackets.

= 2 x (2 - 7i) + 7i x (2 - 7i)

=  4 - 14i + 14i - 49i²

= 4 - 14i + 14i - 49 x -1

= 4 - 14i + 14i + 49

= 4 + 49

= 53

We have only the real part.

So,

The product of (2 + 7i) (2 - 7i) is 53 + 0i.

Thus,

The product of (2 + 7i) (2 - 7i) in the form of a + bi is 53 + 0i.
