the residual plot below suggests which violation(s) of regression assumptions? a. autocorrelation b. multicollinearity c. heteroscedasticity d. nonnormality

Answers

Answer 1

the residual plot below suggests that this violation is Heteroscedasticity

The residual is the discrepancy between the actual value and the model's estimated value. The fundamental premise of regression or time series analysis is that the residual variance or quantity should be constant. As a result, there shouldn't be any patterns visible in the residual scatter plot.

The residuals scatter plot reveals a pattern. The dispersion of residuals is growing at higher values of Docs. As a result, residual variance is not constant.

Heteroscedasticity is present when the residual variance is non-constant. Regression makes the supposition that the residual variance should be constant (Homosceasticity). Consequently, the scatter plot of residuals violates the heteroscedasticity condition.

to rent a certain meeting room, a college charges a reservation fee of $18 and an additional fee of $6 per hour. The chemistry club wants to spend at most $72 on renting the room. what are the possible numbers of hours the cemetery club could rent the meeting room? use t for the number of hours. write your answer as an inequality solved for t.

Answers

Answer:

t ≤ 9 hours

Step-by-step explanation:

Reservation fee = $18

Additional fee per hour = $6

Let x = number of hours

At most in inequality means ≤ less than or equal to

The inequality is

18 + 6t ≤ 72

6t ≤ 72 - 18

Answer:

there is no mode

median: 13.5

Step-by-step explanation:

mean= 14+9+20+5+17+13 = 78

78÷6= 13

range = highest number minus the smallest number

20-5 = 15

the mode is the number that occurs the most

Answers

Answer:

(-6.5, 3)

7.2units

Step-by-step explanation:

Given the coordinate

A =(-26, -15)

B = (13, 21)

Midpoint of A and B is expressed as;

X = -26+ 13/2

X = -13/2

X = -6.5

Y = -15+21/2

Y = 6/2

Y = 3

Hence the required midpoint is (-6.5, 3)

b) The distance between the coordinate (-6.5, 3) and (0,0) is expressed as;

D = √(-3)²+(0+6.5)²

D = √9+42.25

D = √51.25

D = 7.2units

Hence the distance between the midpoint and the base camp is 7.2units

if p and q vary inversely and p is 17 when q is 15, determine q when p is equal to 5

Answers

Answer:

Step-by-step explanation:

q = 51

Writing these statements symbolically, we get p = k/q. This is inverse variation.

Solving for k, we get k = pq. Thus the governing equation is k = pq, or k = (17)(15) = 255.

We then have a specific equation: p = 255/q, or q = 255/p.

If p is 5, q is q = 255/5 = 51

Value of a in term of x = 8/x

Step-by-step explanation:

Given:

14 = ax + 6

Find:

Value of a in term of x

Computation:

⇒ 14 = ax + 6

Step 1; Subtract 6 from both side

⇒ 14 - 6 = ax + 6 - 6

We get step 2

⇒ 8 = ax

Divide x from both side and we get step 3

⇒ 8 / x = ax / x

Step 4

⇒ 8/x = a

Step 5

⇒ a = 8/x

Value of a in term of x = 8/x
