A data set contains three points, and two of the residuals are -10 and -20. What is the third residual?

Answers

The residuals of any data set should get added to zero. If there are three residuals (say A, B, and C) in any data set, then it could be written as A + B + C = 0.

Given are the two residuals -10 and -20 out of three point in a particular data set.

Let's assume A = -10 and B = -20, so that we could find third value C of the given data set.

We know A + B + C = 0

(-10) + (-20) + C = 0

(-30) + C = 0

C = 30

It means that third residual must be 30.

Hence, the final answer is 30.

A triangle and a rectangle are drawn. The triangle's base is equal to the rectangle's length. The triangle's height is equal to the rectangle's width. Which sentence is true?

A.)exactly 1 of these rectangle's can fit inside this triangle.
B.)2 of these rectangles can fit inside this triangle
C.)exactly 1 of these triangle's can fit inside this rectangle
D.)2 of these triangles can fit inside this rectangle

Answers

c is the correct answer

Final answer:

Exactly 1 of these triangles can fit inside this rectangle.

Explanation:

The sentence that is true is exactly 1 of these triangles can fit inside this rectangle. To understand why, let's analyze the dimensions of the triangle and the rectangle. Suppose the base of the triangle is 4 units and the height is 3 units. If the length of the rectangle is also 4 units and the width is 3 units, the triangle will perfectly fit inside the rectangle. However, if the length or width of the rectangle is different from the corresponding dimensions of the triangle, it will not be possible to fit the triangle inside the rectangle without overlapping.

Mr.Johansson's truck weighs 3 tons. How many ounces does it weigh

Answers

Final answer:

To convert the 3-ton weight of Mr. Johansson's truck to ounces, we multiply 3 tons by 2,000 to get pounds and then multiply that figure by 16 to get 96,000 ounces.

Explanation:

Mr. Johansson's truck weighs 3 tons. To convert this weight to ounces, we need to know that one ton is equal to 2,000 pounds and one pound is equal to 16 ounces.

First, we convert tons to pounds:
3 tons x 2,000 pounds/ton = 6,000 pounds

Next, we convert pounds to ounces:
6,000 pounds x 16 ounces/pound = 96,000 ounces

Therefore, the weight of Mr. Johansson's truck is 96,000 ounces. This conversion showcases the application of the conversion factors between tons, pounds, and ounces, providing a precise measure of the truck's weight in a more universally comprehensible unit.

Final answer:

The truck weighs 96,000 ounces.

Explanation:

To convert tons to ounces, we can use the conversion factor that 1 ton is equal to 32,000 ounces.

So, to find how many ounces the truck weighs, we can multiply the weight of the truck in tons by the conversion factor.

Weight of the truck in ounces = Weight of the truck in tons x Conversion factor

Weight of the truck in ounces = 3 tons x 32,000 ounces/ton

Weight of the truck in ounces = 96,000 ounces.

Renee is making a scale diagram of her mp3 player. The length of her scale drawing is 8 inches, and the width is 14 inches. The actual length of the mp3 player is 4 centimeters, and the width is 7 centimeters. what is the scale factor?

Answers

Answer: 2

Explanation:

The scale factor is the ratio between the scale drawing measures and the actual measures.

                                   scale drawing length            8 inches
scale factor = ratio = -------------------------------- =   --------------- = 2
                                        actual length                    4 inches

Also,
                                   scale drawing width             14 inches
scale factor = ratio = ----------------------------- =       --------------- = 2
                                     actual width                      7 inces

As seen the scale factor is 2.

The scale factor is 1:2 or 1/2.

To determine the scale factor between the actual dimensions and the scale drawing, divide the actual length and width by the corresponding values in the scale drawing dimensions. In this case, the scale factor is 1:2 or 1/2.

To find the scale factor:

Calculate the ratio of the actual length to the scale length: 4 cm / 8 in = 0.5Calculate the ratio of the actual width to the scale width: 7 cm / 14 in = 0.5Since both ratios are the same, the scale factor is 1:2 or 1/2.

the length of bill's backyard swimming pool is 60 ft longer than the width if the pool. The surface area of the water is 1600 square ft. What is the width of the pool?

Answers

Given data:
Surface Area of water = A = 1600[tex]ft^{2}[/tex]
Length of the swimming pool = L = 60[tex]ft[/tex] + W
Width of the swimming pool = W =?

Since,
Area = Length * Width
A = L * W

Therefore,
1600 = (60 + W) * W
1600 = 60W + W*W

=> [tex]W^{2} + 60W - 1600 = 0[/tex]

In the above equation(in terms of quadratic formula),
a = 1
b = 60
c = -1600
x = W

Use,

x(for positive) = [tex]x =\frac{ -b + \sqrt{ b^{2} - 4*a*c } }{2*a} [/tex]
Plug-in the values you would get:
x = (-60 + 100) / 2
x = 20 --- (1)

x(for negative) = [tex]x =\frac{ -b - \sqrt{ b^{2} - 4*a*c } }{2*a} [/tex]
Plug-in the values you would get:
x = (-60 - 100) / 2
x = -80 --- (2)

Since x = W = Width, and width CANNOT be negative, therefore, the correct answer is (1):

Ans: Width = 20ft

To find the width of Bill's rectangular pool, set up an equation with 'x' as the width, resulting in x(x + 60) = 1600. Solving this quadratic equation, the width of the pool is found to be 20 feet.

The question asks us to determine the width of Bill's backyard swimming pool given that the pool's length is 60 feet longer than its width and the surface area of the water is 1600 square feet. To solve this, we can set up an equation where the width of the pool is x feet and the length is x + 60 feet. Because surface area is found by multiplying the length by the width for a rectangular object, our equation is x(x + 60) = 1600.

Now, solve for x:

x^2 + 60x = 1600x^2 + 60x - 1600 = 0

We can solve this quadratic equation by factoring or using the quadratic formula. In this case, the equation factors nicely:

(x + 80)(x - 20) = 0

Setting each factor equal to zero gives us:

x + 80 = 0 or x - 20 = 0x = -80 or x = 20

Since a negative width doesn't make sense for a physical object, we discard x = -80 and the width of the pool is 20 feet.

An architect is designing square windows with an area of ( x 2 + 20x + 100) ft2 . The dimensions of the windows are of the form ax + b, where a and b are whole numbers.

a. Find the dimensions of each square window.
b. Find an expression for the perimeter of a window.
c. Find the perimeter of a window when x = 4.

Answers

A) The dimensions are (x+10) by (x+10).
B) The perimeter is given by 4x+40.
C) The perimeter when x is 4 is 56.

The quadratic can be factored by finding factors of c, the constant, that sum to b, the coefficient of x. Our c is 100 and our b is 20; we want factors of 100 that sum to 20. 10*10=100 and 10+10=20, so those are what we need. This gives us (x+10)(x+10 for the factored form.
Since the dimensions are all (x+10), and there are 4 sides, the perimeter is given by 4(x+10). Using the distributive property we have 4*x+4*10=4x+40.
To find the perimeter when x=4, substitute 4 into our perimeter expression:
4*4+40=16+40=56.

What if mac bought8pack of toy boats and then he gave his friend 3boats? If mac has 13 boats now,how many boats were in each pack?

Answers

There were two boats in each car.

To solve for this, we need to set up an algebraic equation.
We have 8 packs of toy boats, meaning there are a specific amount of toy boats per pack, so we have to multiply 8 by a variable, x. Considering this is the total, too, we should let this sit at the end of the equation (=8x). Mac gave his friend 3 toy boats, meaning we will be subtracting 3 from our equation, but this will be on the other side of the equation with 8x (-3). We also have a current total of 13 toy boats after Mac gave away 3 boats, meaning that 13 will have to sit alone (+13).
With this information, let's set up an equation. With what we have, the equation will look like this:
8x - 3 = 13
Now all we have to do is solve for x. To start this off, we should add 3 to both sides to isolate the variable.
8x = 13 + 3; simplify.
8x = 16; All that is left is to divide both sides by 8 and we will have figured out how many toy boats were in each pack.
8x / 8 = x; 16 / 8 = 2.

We are left with our answer, x = 2. That being said, there were 2 toy boats per pack.
