Suppose that a nonzero constant b is added to every value of a generic sample dataset 1 2 3 { , , , , }n x x x x , to produce a new dataset 1 2 3 { , , , , } n x b x b x b x b . Provide a formal mathematical (i.e., algebraic) proof for what happens to the mean, variance, and standard deviation. (Hint: Think of the dotplot for informal motivation.)

Answers

Answer:

Step-by-step explanation:

Suppose there is the addition of a constant "b" to each generic dataset, then, new mean = old mean + b. This will affect the variance and the standard deviation of the resulting dataset to remain the same:

From the information given:

[tex]\mathbf{x_1,x_2,x_3...x_n \ have \ mean \ \overline x }[/tex]

Proof:

If c is added to each data set:

Then,

[tex]\mathbf{x_1+c,x_2+c,x_3+c...x_n+c \ and \ the \ new \ mean \ \overline x = \overline x + c}[/tex]

also;

[tex]\mathbf{New \ Sd^2 = \dfrac{(x_1+c -(\overline x+c))^2+ (x_2+c -(\overline x+c))^2 +...+ (x_3+c -(\overline x+c))^2}{n}}[/tex]

[tex]\mathbf{New \ Sd^2 = \dfrac{(x_1+c -\overline x+c)^2+ (x_2+c -\overline x+c)^2 +...+ (x_3+c -\overline x+c)^2}{n}}[/tex]

[tex]\mathbf{New \ Sd^2 = (x_1- \overline x)^2+ (x_2- \overline x)^2+ ... +(x_n- \overline x)^2}[/tex]

[tex]\mathbf{New \ Sd^2 = old \ sd^2}[/tex]

Now, we calculate the root, applying it's properties. So

[tex]\sqrt{81x^6y^4} = \sqrt{81} \times \sqrt{x^6} \times \sqrt{y^4} = 9 \times x^{\frac{6}{2}} \times y^{\frac{4}{2}} = 9x^3y^2[/tex]

You need a Calculator that has tangent, cosine, & sine on it. Or you can just use Desmos. You can find the angle by using inverse tangent. Since 17 is across from the angle, 17 is opposite and since 16 is right next to the angle, 16 is adjacent. Opposite over adjacent makes tangent. Since you don’t have an angle you need to use inverse tangent instead of just tangent. The way you do inverse tangent on a calculator is click 2nd and then click Tan. I show it in the picture below. After you figure that out all you need to do is in the parentheses put 17/16.

There will be 340 people on a school trip to Washington, D.C. Each school bus holds

45 people, and all the buses will be filled except for the last bus. How many school

buses will be needed and how many people will be on the last bus?

A. 8 buses with 25 people on the last bus

B. 7 buses with 25 people on the last bus

C. 8 buses with 35 people on the last bus

D. 8 buses with 45 people on the last bus

Answers

Step-by-step explanation:

340 people ÷ 45 per bus = number of busses.

340÷45=7.555555555

7 full busses

45 people × 7 busses = 315 people with seats

340 people total - 315 people with seats = 25 people left

answer A. 8 busses with 25 on last bus.

There will be 8 busses needed with 25 on last bus. so option A is correct.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given; There will be 340 people on a school trip to Washington, D.C.

Each school bus holds 45 people, and all the buses will be filled except for the last bus.

So, 340 people ÷ 45 per bus = number of busses.

340÷45 = 7.555555555

The numebr of buses = 7 full busses

Then, 45 people × 7 busses = 315 people with seats

340 people total - 315 people with seats = 25 people left

Hence, There will be 8 busses needed with 25 on last bus. so option A is correct.

explain how you can use fractions strips or number lines to show that 3/4 and 6/8 are equivalent.

Answers

Answer:

answers is down there

Step-by-step explanation:

you can use fraction strips by using them 3/4 and 6/8 because they are equivalent and that's just life :)

3/4 and 6/8 are equivalent numbers/fractions

The fractions are given as:

[tex]\frac 34[/tex] and [tex]\frac 68[/tex]

To model 3/4 using number lines, we do the following steps

Draw a straight lineDivide into 4 equal segmentsPut a mark at the end of the 3rd point

To model 6/8 using number lines, we do the following steps

Draw a straight lineDivide into 6 equal segmentsPut a mark at the end of the 6th point

When both points are compared, then we find out that:

[tex]\frac 34 \equiv \frac 68[/tex]

Hence, 3/4 and 6/8 are equivalent

Step-by-step explanation:

Okay so first of all, we want to find the probability of picking that first purple marble. There are 8 purple marbles you can chose out of a possible 12 marbles, so the probability is 8/12, or 2/3.

Next, find the probability of finding the second purple marble. Since you took out one purple marble already, there are 7 purple marbles you could chose out of a possible 11 marbles, so the probability is 7/11.

To find out the probability of both of these events happening, you multiply these probabilities:

[tex]\frac{2}{3} * \frac{7}{11}\\\frac{2*7}{3*11} \\\frac{14}{33}[/tex]

The answer is : 14/33

You are offered a 30--day trial period at your dream job. However, the owner of the company is a little unusual so the pay options are non-traditional. They offer you two different pay options for the 30 days:
Option 1: You make $60,000 per day.
Option 2: You make 1 penny the first day, 2 pennies the second day, 4 pennies the third day, 8 pennies the fourth day, etc.
Which is $5,368,709.12 after 30 days of working.

Answers

Answer:

The question is not complete but from the flow of thought, the question seems to be about what your choice will be between option 1 and option 2.

The correct answer is

option 2

Step-by-step explanation:

The question is asking you to choose an option that pays more after 30 days. In other to determine the more beneficial option, we will compare both options and select the one that pays more. This is done as follows:

option 1: $60,000 per day, after 30 days =

60,000 × 30 = $1,800,000

option 2 = $5,368,709.12 after 30 days

From the total amounts after 30 days of the two options listed above, option 2 is higher than option 1 by $3,568,709. Therefore, option 2 is a better choice.
