No, the slope for X3 will decrease somewhat in the multiple regression model.

When a third variable, X3, is added to the multiple regression model that is uncorrelated with both height and weight, the inclusion of this variable can affect the relationship between the predictor variables and the outcome variable.

In the simple regression model, where only X3 predicts shoe size, the slope for X3 is 0.1. However, in the multiple regression model where height, weight, and X3 are predictors of shoe size, the inclusion of additional variables can introduce collinearity and affect the relationships between the variables.

The presence of collinearity can lead to changes in the coefficients (slopes) of the predictors. Specifically, the slope for X3 in the multiple regression model is likely to change from its original value of 0.1. It may decrease somewhat as the other predictors (height and weight) account for some of the variance explained by X3.

The extent to which the slope for X3 changes in the multiple regression model depends on the specific relationships and interactions between X3, height, and weight. These changes are determined by the statistical analysis and the data at hand.

Answer:

1

Step-by-step explanation:

Pick two points on the line

(0,1) and (2,3)

Using the slope formula

m = (y2-y1)/(x2-x1)

   = (3-1)/( 2-0)

    = 2/2

  = 1

The slope is 1

Answer:

1

Step-by-step explanation:

To find the slope use the formula y2-y1/x2-x1

First find 2 points of the line

(0, 1) & (3, 4)

Next plug in 4 for y2, 1 for y1, 3 for x2, and 0 for x1

4 - 1/3 - 0 = 3/3

Since 3/3 is simplified to 1, the slope is 1

The Pythagorean triplets for the given values of 'n' are as follows:

For n = 1: (3, 4, 5)

For n = 2: (5, 12, 13)

For n = 3: (7, 24, 25)

For n = 4: (9, 40,41)

To find the Pythagorean triplets for different values of 'n', we can use the formula that generates Pythagorean triples:

For any two positive integers 'm' and 'n' such that m > n, the Pythagorean triplets can be obtained as follows:

a = m^2 - n^2

b = 2mn

c = m^2 + n^2

where 'a', 'b', and 'c' represent the sides of a right-angled triangle.

Let's calculate the Pythagorean triplets for each given value of 'n':

For n = 1:

m = 2

a = m^2 - n^2 = 2^2 - 1^2 = 4 - 1 = 3

b = 2mn = 2 × 2 × 1 = 4

c = m^2 + n^2 = 2^2 + 1^2 = 4 + 1 = 5

Therefore, the Pythagorean triplets for n = 1 are (3, 4, 5).

For n = 2:

m = 3

a = m^2 - n^2 = 3^2 - 2^2 = 9 - 4 = 5

b = 2mn = 2 × 3 × 2 = 12

c = m^2 + n^2 = 3^2 + 2^2 = 9 + 4 = 13

Therefore, the Pythagorean triplets for n = 2 are (5, 12, 13).

For n = 3:

m = 4

a = m^2 - n^2 = 4^2 - 3^2 = 16 - 9 = 7

b = 2mn = 2 × 4 × 3 = 24

c = m^2 + n^2 = 4^2 + 3^2 = 16 + 9

Therefore, the Pythagorean triplets for n = 3 are (7, 24, 25).

For n = 4:

m = 5

a = m^2 - n^2 = 5^2 - 4^2 = 25 - 16 = 9

b = 2mn = 2 × 5 × 4 = 40

c = m^2 + n^2 = 5^2 + 4^2 = 25 + 16 = 41

Therefore, the Pythagorean triplets for n = 4 are (9, 40, 41).

Answer:

  B.  y > 3x -7

Step-by-step explanation:

We can choose the correct inequality based on the y-intercept and the shading.

The dashed line crosses the y-axis at approximately y=-7. This is the value of y when x=0. This observation eliminates choices D, E, F.

The shading on the graph is seen to be above and to the left of the line. This means the variables in relation to the inequality symbol must be ...

  y > ( ) . . . . eliminates choice A

and

  x < ( )  or  ( ) > x . . . . eliminates choice C, confirms choice B

The inequality that matches the graph is y > 3x -7.

__

Additional comment

For looking at shading, we are interested in the relation of the inequality symbol to a variable term with a positive coefficient. If the coefficient is negative, you can do either of ...

That is, if you have -3x < ( ), when considering shading, you can consider the relation x > ( ) with the inequality reversed, or you can consider ( ) < x, which has x on the other side of the inequality. Both of these tell you shading is right of the line, where x-values are greater than those on the line.

Answer:

20

Step-by-step explanation:

If point B is on line segment AC, then we know for sure AB + BC = AC.

To understand this better, draw a line segment, then put a point anywhere on the line segment. There are two line segment divided by that point. If you combine those two line segments then you have your original figure.

So 11 + 9 = 20.

Answer:

560 metres

Step-by-step explanation:

80 cm in metres is 0.8 metres.

After 1 revolution any point on the wheel will be back to the original position before moving. 0.8 times 2, which gives us 1.6 metres. In 1 revolution the bike travels 1.6 metres.

Now 1.6 metres times 350 gives us 560.

So the answer is 560 metres.

The solution of the differential equation with the given initial conditions is y(t) = 4e^(5t).

To find the solution of the differential equation with the given initial conditions, we need to use the method of separation of variables. Here's how:

1. Separate the variables: y'/y = 5

2. Integrate both sides: ∫y'/y dy = ∫5 dt

3. Simplify the integrals: ln(y) = 5t + C

4. Solve for y: y = e^(5t+C) = e^(5t) * e^C

5. Use the initial condition y(0) = 4 to find the value of C: 4 = e^(5*0) * e^C => e^C = 4

6. Substitute the value of C back into the equation: y = e^(5t) * 4 = 4e^(5t)

tThe population in this scenario refers to the entire group of policyholders of the large automobile insurance company.

Set up the hypotheses ; Null hypothesis (H0): The mean age in the population of policyholders is 50.  Alternative hypothesis (Ha): The mean age in the population of policyholders is different from 50. Determine the significance level: The significance level is given as 5%.  Calculate the test statistic: The test statistic for a two-sample t-test is given by:
    t = (sample mean - hypothesized mean) / (standard error)

 In this case, the sample mean is 47.2, and the hypothesized mean is 50. The standard error can be calculated using the formula: standard error = sqrt(variance / sample size).  In this case, the variance is 121 and the sample size is 361. Calculate the degrees of freedom:  For a two-sample t-test, the degrees of freedom is calculated as the sum of the sample sizes minus 2.  In this case, the sample size is 361.  Determine the critical value:  Since the alternative hypothesis is two-tailed (different from 50), we divide the significance level by 2 (5% / 2) to get the critical value for each tail.

Answer:

70

Step-by-step explanation:

Let the no of books bought be x

The cost price of 1 book is 5x

No of the missing book is 15

The remaining book is x-15

The selling price of 1 book is 87

Selling price of (x-15) book is 87

Hence the number of books can be calculated as follows

8(x-15)-5x= 90

8x-120-5x= 90

8x-5x= 90+120

3x= 210

x= 210/3

= 70

Hence the number of books bought is 70

Answer:

Im gonna take a guess and say that the number of students is x and the $ collected is y

Step-by-step explanation:

The general solution of the system is x(t) = Ce^(-9t), y(t) = De^(5C^2/36 e^(-18t)).

We have the system of differential equations:

x/dt = -9x

dy/dt = -(5/2)x^2 y

The first equation has the solution:

x(t) = Ce^(-9t)

where C is a constant of integration.

We can use this solution to find the solution for y. Substituting x(t) into the second equation, we get:

dy/dt = -(5/2)C^2 e^(-18t) y

Separating the variables and integrating:

∫(1/y) dy = - (5/2)C^2 ∫e^(-18t) dt

ln|y| = (5/36)C^2 e^(-18t) + Kwhere K is a constant of integration.

Taking the exponential of both sides and simplifying, we get:

y(t) = De^(5C^2/36 e^(-18t))

where D is a constant of integration.

Therefore, the general solution of the system is:

x(t) = Ce^(-9t)

y(t) = De^(5C^2/36 e^(-18t)).

The speed of the object is 12121 m per week.

What does it mean to do speed?

The object is moving at a speed of 2 centimeters every 7 seconds.

We need to find the speed in m per week.

2 cm = 0.02 m

1 week = 604800 s

7 s =  \(1.65 * 10^{-6} week\)

Speed = distance/time

So,

\(v = \frac{0.02 m}{1.65 * 10^{-6 } week}\)

\(v = 12121.21 m/ week\)

or v = 12121 m/ week

So, the speed of the object is 12121 m per week.
