Rational numbers are written in how many ways?

Answer:

yeah, its 64

Step-by-step explanation:

Answer:

$56.875

Step-by-step explanation:

Given the following data;

Rate = $8.75 per hour

Number of time worked = 6.5 hours

To find the total amount earned;

Total amount = rate * time

Total amount = 8.75 * 6.5

Total amount = $56.875

Therefore, Marcus earned $56.875 last week.

Answer: HOPE THIS HELPS!!!

Step-by-step explanation:

Let a = number of large frames she bought

Let b = number of small frames she bought

--------------------------------------

(1) a+B+=27

(2) 14a+7b=245

-----------------------

There are 2 equations and 2 unknowns

so it's solvable

---------------

Multiply both sides of (1) by 7

and subtract (1) from (2)

(2) 14a+7b=245

(1) -7a-7b=-189

-----------------------

7a=56

a=8

and

(1) a+2B=27

(1) 8+b=27

(1) b=19

------------------

She bought 8 large frames and 19 small frames

------------------

check:

(2) 14+7b=245

(2) 14*8+7*19=245

(2) 112+133+=245

(2) 245=245

Problem 1

Answer: No, it is not a statistical question

Explanation:

This is because the question is directed at a specific family, your family in particular. If the surveyor is only asking one person, then there's no need for statistics since a sample isn't formed.

If the question is posed to many people taking a survey, then it would be statistical in nature. However, no further context or clarification is given, so I'll assume that the question is directed at one person, or one family, only. I think your teacher would say "During which month do families take vacation?" to be more general and involve statistics.

==============================================================

Problem 2

Answer: The statistical variable is the number of tv sets owned, and this variable is quantitative

Explanation:

The variable is what we want to figure out, and it's random in nature. Hence the name "random variable". It takes on nonnegative whole numbers 0,1,2,3,... so we can see the data set is discrete. The term "discrete" in math means that there aren't infinitely many numbers between two values. For example, if we pick 2 and 5, we can see the values 3,4 are between them and that's it. Contrast this with a continuous data set and there are infinitely many real numbers between 2 and 5 (eg: 2.78912 and 3.412)

While it might be tempting to think of a discrete number set as finite, that's not entirely true. We have infinitely many nonnegative whole numbers to work with. Though of course, there's a realistic limit that we arrive to and someone having 277 televisions is completely out of the ordinary, if not impossible.

The data variable "Number of TV sets owned" is not only discrete, but it's also ordinal, interval and ratio data as well. Here's a breakdown of what I mean

Since we have many terms apply to this, it sometimes helps to pick just one and try to have it describe the others implicitly. So we go for ratio data since that encapsulates interval and ordinal data types as well. If something is ratio, then automatically it must be ordinal and interval. Division depends on the numbers being well ordered, and that gaps between values make sense and are consistent.

To recap, the data type is quantitative, discrete, and we have a ratio scale.

The variable "number of tv sets owned" is not categorical since the choices to pick from 0,1,2,3,... aren't names; instead they are numbers in which we can perform math operations on and have it make sense. So that's why we go for quantitative data instead of categorical. If it asked "what brand of TV are owned by families?", then the categories of the various brand names would be the answer choices, and lead to categorical data.

Side note: categorical data is always qualitative

Answer:

78-x=61, subtract by 61 on both sides to get 17-x=0, so x would have to be 17

Answer:

[tex]T_7 = 11[/tex]

[tex]T_n = 2n- 3[/tex]

Step-by-step explanation:

Given

[tex]S_n = n^2 -2n[/tex]

[tex]T_n = S_n - S_{n-1}[/tex]

Solving (a): T7

Substitute 7 for n in [tex]T_n = S_n - S_{n-1}[/tex]

[tex]T_7 = S_7 - S_{7-1}[/tex]

[tex]T_7 = S_7 - S_6[/tex]

Calculate S7 and S6

[tex]S_n = n^2 -2n[/tex]

[tex]S_7 = 7^2 - 2 * 7 = 35[/tex]

[tex]S_6 = 6^2 - 2 * 6 = 24[/tex]

So:

[tex]T_7 = 35 -24[/tex]

[tex]T_7 = 11[/tex]

Solving (b): Tn

[tex]T_n = S_n - S_{n-1}[/tex]

Where [tex]S_n = n^2 -2n[/tex]

Calculate[tex]S_{n-1}[/tex]

We have:

[tex]S_{n-1} =(n-1)^2 - 2(n-1)[/tex]

Open brackets

[tex]S_{n-1} = n^2 -2n + 1 -2n +2[/tex]

[tex]S_{n-1} = n^2 -2n-2n + 1 +2[/tex]

[tex]S_{n-1} = n^2 -4n + 3[/tex]

So:

[tex]T_n = S_n - S_{n-1}[/tex]

[tex]T_n = n^2 - 2n - (n^2 -4n + 3)[/tex]

[tex]T_n = n^2 - 2n - n^2 +4n - 3[/tex]

Collect Like Terms

[tex]T_n = n^2 - n^2- 2n +4n - 3[/tex]

[tex]T_n = 2n- 3[/tex]

The value of Tn and T7 are 2n - 3 and 11 respectively

Given the formula for calculating the nth term as a function of sum expressed as:

[tex]S_n - S_{n-1} =T_n[/tex]

If Sn = n² - 2n, then;

Sn-1 = (n-1)² - 2(n-1)

Tn =  n² - 2n - [(n-1)² - 2(n-1)]

Tn = n² - 2n- (n² - 2n + 1 - 2n + 2)

Tn = -1 + 2n - 2

Tn = 2n - 3

For T7;

T7 = 2(7) - 3

T7 = 11

Hence the value of Tn and T7 are 2n - 3 and 11 respectively

Answer:

B. $8,631.96

Step-by-step explanation:

Create an equation where x is the number of years and y is the car's value

y = 48500(0.75)^x

Plug in 6 as x, since the question asks for the value in 6 years, and simplify:

y = 48500(0.75)^6

y = 8631.96

So, in 6 years, the car will be worth $8,631.96

Answer (assuming it can be in slope-intercept form):

[tex]y = -\frac{6}{5} x+3[/tex]  

Step-by-step explanation:

1) First, use the slope formula [tex]m =\frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope of the line. Substitute the x and y values of the given points into the formula and solve:

[tex]m =\frac{(-3)-(3)}{(5)-(0)} \\m = \frac{-3-3}{5-0}\\m = \frac{-6}{5}[/tex]

So, the slope is [tex]-\frac{6}{5}[/tex].  

2) Now, use the slope-intercept formula [tex]y = mx + b[/tex] to write the equation of the line in slope-intercept form. All you need to do is substitute real values for the [tex]m[/tex] and [tex]b[/tex] in the formula.

Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{6}{5}[/tex] for it. Since [tex]b[/tex] represents the y-intercept, substitute 3 for it. (Remember, the y-intercept is the point at which the line hits the y-axis. All points on the y-axis have an x-value of 0. Notice how the given point (0,3) has an x-value, too, so it must be the line's y-intercept.) This gives the following equation and answer:

[tex]y = -\frac{6}{5} x+3[/tex]
