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.

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 is an equivalent expression?

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

The given expression is 1/4(2-5x+6).

The equivalent expression is

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.

if the r-value, or correlation coefficient, of a data set is 0.854, what is the coefficient of determination to three decimal places?

Answers

To find the coefficient of determination, square the correlation coefficient:
(0.854)² = 0.729316.  To three decimal places, this would be 0.729.

Answer with explanation:

Coefficient of determination(r²), is defined as, how well the data values are associated with each other when Regression line is drawn. In regression analysis, the coefficient of determination  measures , how well the regression predictions approximate the real data points, means it measures the closeness between two variables.The Value of r², lies between  0 to 1. If value of r²=1, it shows ,regression line that is data values are Perfectly associated with each other.

If ,r²=0, it means there is no variation between two variables.There is 0% variation between two variables.

Coefficient of Variation=[Correlation coefficient]²

                                         =r²

                                        =(0.854)²

                                        =0.854 × 0.854

                                         =0.729316

                                          =0.730(Approx)

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.

beer Bottles are filled so that they contain an average of 475 ml of beer in each bottle. Suppose that the amount of beer in a bottle is normally distributed with a standard deviation of 8 ml.

Answers

I attached the rest of your question in the image below.
We use the normal distribution density function f(z)  to find the probability of a specific range of values.
Z= ((X-μ)/σ)
μ = 475σ = 8
a) X< 470 ml
P[X<470] = P[Z<(470-475)/8] = P[Z<(470-475)/8] = P[Z<-0.625] = 0.2659

b) 6 pack with a mean of less than 470ml
Z = ((X-μ)/(σ/√n))
Z = (470-475)/(8/√6) 
P [Z<-1.53] = 0.063
c) 12 pack with a mean of less than 470ml
Z = ((X-μ)/(σ/√n))
Z = (470-475)/(8/√12) 
P [Z<-2.165] = 0.0152
 

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.
