Consider the following statements:
I. Multicollinearity is present when there is a high degree of linear correlation between the predictors.
II. A regression analysis between weight (y in pounds) and height (x in inches) resulted in the following least squares line: y-hat = 135 + 6x + errors. This implies that if the height is zero, the weight is 135 pounds in this linear model.
a. I is true and II is false.
b. I is false and II is true.
c. Both I and II are true.
d. Both I and II are false.
e. More information is needed for each statement in order to tell which is true or false.

Answers

Answer 1

Answer:

d. Both I and II are false

Step-by-step explanation:

When there is a high degree of linear correlation between the predictors the errors are found.

The basic objective of the regression model is to separate the dependent and independent variables. So if the variables have high degree of linear correlation then the multi collinearity causes problems or has errors. It is not necessary that multi collinearity must be present with high degree of linear correlation.

For example we have 3 variable of heat length and time. And all of them have a high degree of correlation. With increase in heat and time the length increases . But for multi collinearity with the increase of time and decrease of heat length does not increase. So this causes errors.

y-hat = 135 + 6x + errors

The linear relationship between height and weight is inexact. The deterministic relation in such cases is then modified to allow the inexact relationship between variables and a non deterministic or probabilistic model is obtained which has  error which are unknown random errors.

y- hat= a + bXi + ei   (i=1,2,3...)

ei are the unknown random errors.

So both statements are false.

Answer:

376 people

Step-by-step explanation:

25% is 94

to get the there 75% divide 94 by 25% or .25 and you get 376. 25% of that is 94.

Alright i believe the answer is 376, to find the answer we need to find the percent of 1/4 and it is 25% so now i must find how many 25's can fit into the 100% or the whole, in this case 4 can fit into it so now i must multiply 94 * 4 = 376

so i think that is the answer is 376...

Identify the graph that displays the speed of a car accelerating onto a highway until it reaches the speed limit, and then continuing on the highway at the speed limit. ​

Answers

Answer: D

Step-by-step explanation:

Graph D shows the car increasing speed over time, then, the flat line shows the car remains at a constant speed. In order for the scenario to apply, there needs to be a line parallel to the x-axis which shows a speed remaining the same over a given amount of time. D is the only graph which has this feature, thus this graph displays the scenario.

a. 21.3 m
c. 19.3 m
b. 25 m
d. 23 m

Answers

Answer: 21.3m

Step-by-step explanation:

The height of the kite of the ground would be calculated as:

We have to calculate the question using a right angled triangle that has angle ACB as 90° while angle CAB will be 40°.

Therefore, the height of the kite would be:

= 30 sin 40 + 2

= 30 (0.6428 ) + 2

= 19.284 + 2

= 21.284 m

= 21.3 m

A customer ordered a product online for $299 and was charged an additional $10 for shipping and handling. The customer received a rebate of $99 and a $25 credit for turning in an old cell phone. After a tax of 4% was applied, how much did the customer pay for the product?

Answers

Answer:

the  amount paid by the customer for the product is $192.40

Step-by-step explanation:

The computation of the amount paid by the customer for the product is shown below:

= Total amount + Total amount × tax rate

= ($299 + $10 - $99 - $25) + ($299 + $10 - $99 - $25) × 0.04

= $185 + 185 × 0.04

= $185 + $7.4

= $192.40

Hence, the  amount paid by the customer for the product is $192.40

Answer:

  B. The graph of h(x) opens downward.

  D. The graph of h(x) is wider.

Step-by-step explanation:

The negative leading coefficient causes the graph to be reflected across the x-axis, making it open downward.

The leading coefficient magnitude less than 1 compresses the graph vertically, giving it a wider appearance.

Answer:

B

Step-by-step explanation:

The solution is Option B.

The equation which does not satisfy the relation is 3 ( x + 6 ) = 30

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of x in the diagram be = 3

So , the total number of x = 3x

The sum of the values in the box = 30

So , the equation will be

6 + x + x + x = 30

On simplifying the equation , we get

6 + 3x = 30   be equation (1)

a)

6 + 3x = 30

The equation satisfies

b)

3 ( x + 6 ) = 30

On simplifying the equation , we get

3x + 18 = 30

The equation does not satisfy

c)

3x = 30 - 6

Adding 6 on both sides of the equation , we get

3x + 6 = 30

The equation satisfies

d)

30 = 3x + 6

The equation satisfies

Hence , the equation which does not satisfy the relation is 3 ( x + 6 ) = 30
