Determine the slope and the y- intercept of the line 7x +3y = -8

Answers

Answer:slope is -7/3 and x=0 y=-8/3

Step-by-step explanation:

The slope of the line is -7/3

The y-intercept of the line is -8/3.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

7x + 3y = -8

3y = -8 - 7x

3y = -7x - 8

y = (-7/3)x - 8/3

This is in the form of y = mx + c

Now,

Slope = -7/3

y-intercept = -8/3

Thus,

The slope is -7/3 and the y-intercept is -8/3.

Required:
a. Use the α =0.05 significance level and the six-step hypothesis-testing process to check if there is a difference in the mean flight times among the three airlines.
b. Develop a 95% confidence interval for the difference in the means between Goust and Cloudtran

Answers

Solution :

We know that

[tex]$H_0: \mu_1 = \mu_2=\mu_3$[/tex]

[tex]$H_1 :$[/tex] At least one mean is different form the others (claim)

We need to find the critical values.

We know k = 3 , N = 35, α = 0.05

d.f.N = k - 1

       = 3 - 1 = 2

d.f.D = N - k

        = 35 - 3 = 32

SO the critical value is 3.295

The mean and the variance of each sample :

Goust                      Jet red                 Cloudtran

[tex]$\overline X_1 =50.5$[/tex]           [tex]$\overline X_2 =50.07143$[/tex]        [tex]$\overline X_3 =55.71429$[/tex]

[tex]$s_1^2=19.96154$[/tex]      [tex]$s_2^2=14.68681$[/tex]         [tex]$s_3^2=36.57143$[/tex]

The grand mean or the overall mean is(GM) :

[tex]$\overline X_{GM}=\frac{\sum \overline X}{N}$[/tex]

         [tex]$=\frac{51+51+...+49+49}{35}$[/tex]

        = 52.1714

The variance between the groups

[tex]$s_B^2=\frac{\sum n_i\left( \overline X_i - \overline X_{GM}\right)^2}{k-1}$[/tex]

     [tex]$=\frac{\left[14(50.5-52.1714)^2+14(52.07143-52.1714)^2+7(55.71426-52.1714)^2\right]}{3-1}$[/tex]

   [tex]$=\frac{127.1143}{2}$[/tex]

   = 63.55714

The Variance within the groups

[tex]$s_W^2=\frac{\sum(n_i-1)s_i^2}{\sum(n_i-1)}$[/tex]

    [tex]$=\frac{(14-1)19.96154+(14-1)14.68681+(7-1)36.57143}{(14-1)+(14-1)+(7-1)}$[/tex]

   [tex]$=\frac{669.8571}{32}$[/tex]

  = 20.93304

The F-test  statistics value is :

[tex]$F=\frac{s_B^2}{s_W^2}$[/tex]

  [tex]$=\frac{63.55714}{20.93304}$[/tex]

  = 3.036212

Now since the 3.036 < 3.295, we do not reject the null hypothesis.

So there is no sufficient evidence to support the claim that there is a difference among the means.

The ANOVA table is :

C) C, B, D, E, A, F
D) A, B, C, D, E, F

Answers

Answer:

C) C, B, D, E, A, F

Step-by-step explanation:

The closer the data points are to each other along the line of best fit on a scatter plot, the greater the correlation coefficient and vice versa.

Therefore, the scatter plot that has the least correlation coefficient would be the scatter plot with the data points that are farther apart from each other along the line of best fit which is C, followed by B, D, E, A, and F.

he first date went well. You are still dating the same person and still looking for a great person to spend your life with. You are cautiously moving forward with the relationship and know that if they are a great match, their likelihood of being kind to animals is 0.9 whereas their likelihood of being kind to animals if they are not a great match is 0.7. You see that your prospective spouse is kind to animals. What is the probability that they are a great match now?

Answers

Answer:

0.125 = 12.5% probability that they are a great match now.

Step-by-step explanation:

To solve this question, we need the probability of a person being a great match, which i will use 0.1.

This question is solved using conditional probability.

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Is kind to animals.

Event B: Is a great match.

Probability of being kind to animals:

0.9 of 0.1(Is a great match).

0.7 of 1 - 0.1 = 0.9(is not a great match). So

[tex]P(A) = 0.9*0.1 + 0.7*0.9 = 0.72[/tex]

Probability of being kind to animals and a great match:

0.9 of 0.1. So

[tex]P(A \cap B) = 0.9*0.1 = 0.09[/tex]

What is the probability that they are a great match now?

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.09}{0.72} = 0.125[/tex]

0.125 = 12.5% probability that they are a great match now.

A writer buys a new laptop for $1866. Every year the laptop decreases in value by 20%.

Answers

Answer:

the answer is A

A function that represents a $1866 laptop that decreases in value by 20% each year is f(n)=1866(1.2)ⁿ.

What is the function?

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Given that,

$1866 laptop that decreases in value by 20% each year.

Here, f(n)=1866(1+20%)ⁿ, where n is the number of years

f(n)=1866(1+20/100)ⁿ

f(n)=1866(1.2)ⁿ

Therefore, a function that represents a $1866 laptop that decreases in value by 20% each year is f(n)=1866(1.2)ⁿ.

The p value is: 0.0301

Step-by-step explanation:

Given

[tex]\mu = 131520[/tex]

[tex]\bar x = 124247[/tex]

[tex]n = 30[/tex]

Required

Determine the p value

First, calculate the standard deviation of the given data.

This is calculated as:

[tex]\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n}}[/tex]

So, we have:

[tex]\sigma = \sqrt{\frac{(83700 - 124247)^2 + (84380- 124247)^2 + (89380- 124247)^2 + ..... + (156920- 124247)^2 + (168370- 124247)^2}{30}}[/tex]

[tex]\sigma = \sqrt{\frac{13427820070}{30}}[/tex]

[tex]\sigma = \sqrt{447594002.333}[/tex]

[tex]\sigma = 21156[/tex]

The test statistic is then calculated as:

[tex]t = \frac{\bar x - \mu}{\sigma/\sqrt n}[/tex]

[tex]t = \frac{124247 - 131520}{21156/\sqrt{30}}[/tex]

[tex]t = \frac{-7273}{21156/5.48}[/tex]

[tex]t = \frac{-7273}{3860.58}[/tex]

[tex]t = -1.88[/tex]

The p value is calculated as:

[tex]P(Z > -1.88)[/tex]

[tex]P(Z>-1.88) = 0.030054[/tex]

[tex]P(Z>-1.88) = 0.0301[/tex] --- approximated.

Hence, the p value is: 0.0301

The distance between two coordinate points is 11.66 units.

What is distance formula?

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x₁, y₁) and (x₂, y₂) is Distance = √[(x₂-x₁)²+(y₂-y₁)²].

The given coordinate points are (-3, -2) and (7, 4)

Substitute (x₁, y₁) =(-3, -2) and (x₂, y₂)=(7, 4) in distance formula, we get

Distance = √[(7+3)²+(4+2)²]

= √(100+36)

= √136

= 11.66 units

Therefore, the distance between two coordinate points is 11.66 units.

Area of triangle ABC = 6 square units

Step-by-step explanation:

By applying Pythagoras theorem in right triangle ADC,

AC² = AD² + CD²

3² = (1.8)² + CD²

9 - 3.24 = CD²

CD = √5.76

CD = 2.4 units

By applying mean ratio theorem,

[tex]\frac{AD}{CD}=\frac{CD}{DB}[/tex]

CD² = AD × DB

(2.4)² = 1.8 × DB

DB = [tex]\frac{5.76}{1.8}[/tex]

DB = 3.2 units

AB = AD + DB

AB = 1.8 + 3.2

AB = 5 units

Since, area of a triangle ABC = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                                = [tex]\frac{1}{2}(\text{AB})(\text{CD})[/tex]

What is a graph?

In math, graph science is the theory of geometric structures called graphs that are used to represent pairwise different objects. Vertices—also known as nodes or points—that are joined by edges make form a network in this sense.

Undirected graphs, where edges connect two vertices equally, and focused therapy, where edges connect two vertices unevenly, are distinguished.

As per the given information in the question,

Here mirror (x = 2) is vertical, hence only x-coordinate changes vertical distance from x-axis will not change.

For point k(3, 0)

It is one unit right side or x  = 2. So, its  image point will be one unit left side that is k'(1, 0).

For point L(0, -4)

It is two unit left side, so L' will be 2 unit right side of x = 2, so the point will be L'(4, -4)

Similarly, point J(1, -1) will become J'(3, -1).
