STATS QUESTION PLEASE HELP AND EXPLAIN!


A least squares regression line was calculated to relate the length (cm) of newborn boys to their weight in kg. The line is weight = -5.58 + 0.1686 length. A newborn was 48cm long and weighed 3 kg. According to the regression model, what was his residual? What does that say about him?


1) WHAT WAS HIS RESIDUAL?


2) WHAT DOES THAT SAY ABOUT HIM? SELECT THE CORRECT CHOICE AND FILL IN ANY ANSWER BOXES TO COMPLETE YOUR ANSWER (round to three decimal places as needed)

a. the newborn weighs ____ kg less than the weight predicted by the regression equation

b. the newborn weighs _____ kg more than the weight predicted by the regression equation

c. the newborn weighs the same as the weight predicted by the regression equation

Answers

Answer 1

Answer:

0.487 kg

b.) the newborn weighs 0.487kg more than the weight predicted by the regression equation

Step-by-step explanation:

Given the Regression equation:

Weight = - 5.58 + 0.1686 length

Length of newborn = 48 cm

Actual Weight of newborn = 3kg

Predicted weight from regression model:

Weight = - 5.58 + 0.1686(48)

Predicted Weight = 2.513kg

Hence, residual = (Actual - predicted)

Residual = (3kg - 2.513kg) = 0.487kg

Since the actual weight is more or greater than the predicted weight:

b.) the newborn weighs 0.487kg more than the weight predicted by the regression equation

Answers

Answer:

x=3

Step-by-step explanation:

6x - 2 = x + 13

subtract 1x from both sides

5x - 2 = 13

isolate the 5x by adding 2 to both sides

5x = 15

finnaly devide both by 5

x = 3

Answer:

      -7

Step-by-step explanation:

     1.6x-2=x+13

   +1.6x      +1.6x

          -2=2.6x+13

          -13        -13

1-Describe the error in the way the calculation of the slope of the two points is set up and/or solved. Please be specific. Do not just state what the slope should be. Describe the error.
2- Use the same two points from the error analysis question above and show how to calculate the slope correctly. Then, use the correct slope and one of the points to write the equation in point-slope form of the line. Show all work!

Answers

Answer:

Please check explanations for answer

Step-by-step explanation:

Let’s have two points (5,10) and (15,20)

1. Let’s find the slope of these two points

Mathematically, the slope can be calculated using the formula;

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

So m = (20-10)/(5-15) = 10/-10 = -1

The error here is the formula used in calculating the slope

The formula should be;

m = (y2-y1)/(x2-x1) and not x1-x2

2. To calculate the slope correctly, we have;

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

So the slope will be;

m = (20-10)/(15-5) = 10/10 = 1

In the point slope form, the equation can be represented as;

y-y1 = m(x-x1)

Let’s use the point (5,10)

y- 10 = 1(x-5)

The above is the point slope form

using one of the points and the correct slope of the line

The triangle below has been reduced by a scale of 0.4. A large triangle has a base of 30 centimeters and height of 10 centimeters. A smaller triangle does not have dimensions provided. What is the area of the reduced triangle? 24 centimeters squared 60 centimeters squared 75 centimeters squared 375 centimeters squared

Answers

Answer:

24 centimeters squared(cm²)

Step-by-step explanation:

The triangle below has been reduced by a scale of 0.4.

A large triangle has a base of 30 centimeters and height of 10 centimeters.

Hence, reducing the large triangle by the given scale ratio, we have :

Height = 10cm × 0.4 = 4cm

Base = 30cm × 0.4 = 12 cm

Hence, the area of the smaller triangle

= Area = 1/2 × Base × Height

Height = 4 cm

Base = 12 cm

Area = 1/2 × 4 × 12

= 24 cm²

A clothes hanger is in the shape on an isosceles triangle. If the hanger is 70° wide what are the base angles?

Answers

Answer:

55°

Step-by-step explanation:

Given parameters:

      Angles in the triangle;

                   70°, X° and X°

The triangle is an isosceles triangle;

  In all triangles, the sum of the interior angles is 180°

  So;

            70° + X° + X° = 180°

            70° + 2X° = 180°

                      2X°  = 180° - 70°

                      2X° = 110°

                        X°  = [tex]\frac{110}{2}[/tex]  = 55°

A round plate has a radius of 8.25 inches. What is the circumference of the plate?

Answers

Answer: The circumference of the plate = 51.86 inches.

Step-by-step explanation:

Given : The radius of a round plate = 8.25 inches

Formula: circumference of a circle = [tex]2\pi r[/tex] , where r = radius of circle .

Then, the circumference of the plate [tex]=2\times\dfrac{22}{7}\times8.25[/tex]   [ [tex]\pi=\dfrac{22}{7}[/tex] ]

[tex]=51.857142857\approx51.86\ \text{inches}[/tex]

Hence, the circumference of the plate = 51.86 inches.

What is the equation written in vertex form of a parabola with a vertex of (3,6) that passes
through point (4,4)?

Answers

Answer:

            f(x) = -2(x - 3)² + 6

Step-by-step explanation:

The vertex form of an equation of the parabola:  

                                                         f(x) = a(x - h)² + k

the vertex is (3, 6)  ⇒   h = 3,  k = 6

so:

      f(x) = a(x - 3)² + 6

The parabola goes through the point (4, 4) ⇒   x=4,  f(x)=4

 4 = a(4 - 3)² + 6

 4 = a(1)² + 6

-6           -6

- 2  = a

It means the equation of the parabola in vertex form:

                                f(x) = -2(x - 3)² + 6
