Answer:

D

Step by step explanation:

[tex]F = \frac{9}{5}C + 32[/tex]

The main objective is to isolate C and to make C the subject of the equation:

[tex]= F - 32= \frac{9}{5} C[/tex]

[tex]= C = \frac{5}{9} (F - 32)[/tex]

Now substitute the given value of F:

[tex]C = \frac{5}{9} (68-32)[/tex]

[tex]=C = \frac{5}{9} (36)[/tex]

[tex]= C = 20^{o} C[/tex]

Answer:

D. C = 5/9 ( F - 32 ) ; conversion: 68° F = 20° C

The mapping diagram does not show a function, because the input -1 is mapped into two different values.

A function is a relation that maps elements from one set (called the domain) into another set (called the range), such that each input can be mapped into only one value.

In this case, we have a relation that maps elements from set A into set B. And you can see that the element -1 is mapped into two different values ( which are 8 and 9), then the mapping does not repsent a function.

Hair color Categorical data is a type of data that can be stored into groups or categories with the aid of names.

Statistical information made up of categorical variables—data that have been divided into categories—is known as categorical data. A set of grouped data is one of example. More specifically, countable qualitative data or quantitative data clustered within predetermined intervals could be used to create category data. The information is condensed into a probability table. However, the word "categorical data," which is used to describe data sets, is used when discussing data analysis. It should be noted that although the data set includes some categorical variables, it may also include non-categorical variables.

Categorical data is a collection of information that is divided into groups. I.e, if an organization or agency is trying to get a biodata of its employees, the resulting data is referred to as categorical. This data is called categorical because it may be grouped according to the variables present in the biodata such as sex, state of residence, etc.

x^3 = 1000

Step-by-step explanation:

Answer:

The expression that represents the verbal phrase "One-fourth times a number n, minus thirty" is (1/4)n - 30.

An equation for a linear function is, [tex]h(x)[/tex] = 56[tex]x[/tex] - 63 where h(7)=329 and h(11)=553.

Given that,

h(7)=329 and h(11)=553

Linear function, y = [tex]mx + c[/tex]

Let, h = y and [tex]x =x[/tex]

A function whose graph is a straight line and which is represented by an equation of the form y = mx + c where a and b are constants, m does not equal zero, and x is any real number.

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y).

So,

[tex]h(x)[/tex] = [tex]mx + c[/tex]

When,

[tex]x[/tex] = 7 , [tex]h(x)[/tex] = 329

( [tex]x_{1}[/tex] , [tex]h(x_{1} )[/tex] ) = ( 7 , 329 )      (Equation-1)

When,

[tex]x[/tex] = 11 , [tex]h(x)[/tex] = 553

( [tex]x_{2}[/tex] , [tex]h(x_{2} )[/tex] ) = ( 11 , 553 )         (Equation-2)

Linear function,

[tex]\frac{h(x)-h(x_{1} )}{x-x_{1} }[/tex] = [tex]\frac{h(x_{2} )-h(x_{1} )}{x_{2} -x_{1} }[/tex]

We can substitute equation -1 and 2

[tex]\frac{h(x)-329}{x-7}[/tex] = [tex]\frac{553-329}{11-7}[/tex]

[tex]\frac{h(x)-329}{x-7}[/tex] = 224/4

[tex]\frac{h(x)-329}{x-7}[/tex] = 56

[tex]h(x)[/tex] - 329 = 56 ( [tex]x-7[/tex] )

[tex]h(x)[/tex] - 329 = 56[tex]x[/tex] - 392

[tex]h(x)[/tex] = 56[tex]x[/tex] - 392 + 329

[tex]h(x)[/tex] = 56[tex]x[/tex] - 63

Therefore,

An equation for a linear function is, [tex]h(x)[/tex] = 56[tex]x[/tex] - 63 where h(7)=329 and h(11)=553.

Answer:

Numbers on die = 1, 2, 3, 4

Colors on board = Red, Green, Blue, Orange (equal sized sections)

To find:

The number of different possible outcomes are there if she rolls a fair die in the board.

Solution:

According to the given information,

The total possibilities for numbers = 4

Total possibilities for colors = 4

Total possibilities = Possibilities for number × Possibilities for colors

                            = 4x4

                            = 16

So, total 16 possible outcomes are there if she rolls a fair die in the board.

Let Red=R, Green=G, Blue=B, Orange=O, then list of total possible outcomes is:

{1R,1G,1B,1O,2R,2G,2B,2O,3R,3G,3B,3O,4R,4G,4B,4O}

Therefore, the total possible outcomes are 16 and the lies of outcomes is {1R,1G,1B,1O,2R,2G,2B,2O,3R,3G,3B,3O,4R,4G,4B,4O}.

There are 8 different possible outcomes if Rashon rolls a pyramid-shaped die labeled with 4 sides and flips a coin.

It is a branch of mathematics that deals with the occurrence of a random event.

If Rashon rolls a pyramid-shaped die that has four sides labeled 1 to 4, then the number of possible outcomes for the die roll is 4.

Additionally, flipping a coin has 2 possible outcomes, either heads or tails.

To find the total number of possible outcomes for rolling the die and flipping the coin, we need to multiply the number of outcomes for the die roll by the number of outcomes for the coin flip.

So, the total number of possible outcomes for rolling the die and flipping the coin is:

4 (number of die outcomes) x 2 (number of coin outcomes) = 8

Therefore, there are 8 different possible outcomes if Rashon rolls a pyramid-shaped die labeled with 4 sides and flips a coin.

All parts of the problem regarding die rolls have been solved and explained below.

In order to find the probability of getting any one point out of the 6 after rolling the die, we first need to Add up all of the number of points in the die, that is -

= 1+2+3+4+5+6

= 21.

We also know that after any roll of one die, the probability of getting about one particular point is 1/6.

So, the expected number of points after one roll can be calculated is-

= 21/6= 3.5

After two rolls, we can just twice the probability of it happening before-

= (2 x 21)/6 = 7.

Similarly, after 100 rolls =  350, and after N rolls, 3.5(N).

Suppose after walking 3.5 miles west, the first hiker's position is A, then after going 1.5 miles north from A his final position is B,

Similarly, after walking 2 miles east, the second hiker's position is C then going towards 0.5 miles south his final position is D.

By making the diagram of this situation,

Let D' is the point in line AB,

Such that, AD' = CD

In triangle BD'D,

BD' = AB + AD' = 1.5 + 0.5 = 2 miles,

Answer:

f(x) = -4[tex]x[/tex] - 2 or y = -4[tex]x[/tex] - 2

Step-by-step explanation:

In this question, you should use the graph to write the function/equation in slope intercept form.

y = mx + b where m is the slope and b is the y intercept

To calculate the slope, you can use rise/run between any two points. I will use the points (-2, 6) and (0, -2). In these points, the "rise" would be -8 as that is the number of units they are away from each other vertically. It is negative because the line obviously has a negative slow as it is travelling from up to down. The run in this case would be 2 as that is the distance the two points are away from each other horizontally.

Then, substitute.

[tex]\frac{-8}{2}[/tex] = -4, so m = -4

Now we will find the b value.

B is the y-intercept, or what the y value of the coordinate of the point that the line touches the y-axis. The coordinate is (0, -2). Therefore, the b value is 2.
