The scatter chart below displays the residuals verses the dependent variable, x. Which of the following conclusions can be drawn

based upon this scatter chart? a. The residuals are normally distributed. b. The model over predicts the value of the dependent variable for small values and large values of the independent variable. c. The model fails to capture the relationship between the variables accurately, and there may exist nonlinear relationship. d. The residuals have a constant variance.

Answer: Hello the scatter plot related to your question is missing attached below is the scatter plot

answer :  The model fails to capture the relationship between the variables accurately, and there may exist nonlinear relationship ( C )

Step-by-step explanation:

The conclusion that can be drawn based upon the scatter chart is that The model fails to capture the relationship between the variables accurately, and there may exist nonlinear relationship

<em>A scatter plot helps in observing the relationship within different numeric variables but the scatter plot attached fails in the showing the actual relationship </em>

Cerrena [4.2K]
4/105 In total there are 2+4+1+8=15 The probability of taking a blue is number of blue divided by number of total, so that would be 4/15. Since, it is not replaced, we can now say that there are 1 less marbles in the bag (since we took out a blue). Now probability of getting a green marble is:2/14=1/7

What the explicit formula of 3 5 7 9
SIZIF [17.4K]

Answer:

a_{n}=3+2(n-1)

Step-by-step explanation:

Given:

The given sequence is 3, 5, 7, 9

The difference between the second and first term is 5 - 3 = 2

The difference between the third and second term is 7 - 5 = 2

The difference between the fourth and third term is 9 - 7 = 2

So, there is a common difference of 2. Thus a sequence which has the same difference is known as an arithmetic sequence.

The explicit formula to determine the n^{th} term of an arithmetic sequence is given as:

a_n=a_1+(n-1)d

Where, a_1\rightarrow 1^{st}\ term, d\rightarrow \textrm{common difference}

Plug in 3 for a_1 and 2 for d. This gives,

a_{n}=3+(n-1)\times 2

Therefore, the explicit formula to represent the given sequence is:

a_{n}=3+2(n-1)

Xº<br> 50°<br> What is the value of x?
Sav [38]

Answer:

65

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180

one of the angle is given as 50 degrees so:

50 + x + x = 180

50 + 2x = 180 subtract 50 from both sides

2x = 130 divide both sides by 2

x = 65

pychu [463]

Answer:

10

Step-by-step explanation:

GIVEN: Josiah is playing a computer game that lets him customize a story There are 5 different eras and 2 location to choose from.

TO FIND: How many different stories can Josiah construct.

SOLUTION:

Total different eras =5

Total different locations =2

He can choose one era and one location.

Total different stories that Josiah can construct =^5C_1\times^2C_1

                                                                               =10

Hence Josiah can construct 10 different stories.
