does the following relation form a function if so how do you know

the relation is : (1,3) (5,6), (4, 3), and (2, 5)

Answer:

\(\frac{x}{27} =.075\)

\(\frac{x}{.075} = 27\)

Step-by-step explanation:

Let x represent the number that is 7.5% of 27.

The way I came up with my expressions is I took this equation and rearranged it:

\((.075)(27) = x\)

Just divide out one of the numbers to get another expression.

I hope this helps!!

Answer:

Perimeter is 126cm and area is 972\(cm^2\)

Step-by-step explanation:

Scale factor means you multiply the dimensions by the factor. In this case 4.5

The width 6cm becomes 27cm. The length 8cm becomes 36cm.

Perimeter = 2*L + 2*W, L is length and W is width.

\(P=27*2cm+36*2cm\\P=54cm+72cm\\P=126cm\)

Area = L*W

\(A=27cm*36cm\\A=972cm^2\)

Answer:

y=2x-6

Step-by-step explanation:

y+4=-2(x-1)

Since the slope intercept form is in the form of:

y=mx+c

Making above equation in this form.

y+4=-2(x-1)

opening bracket

y+4=2x-2

subtracting both side by 4.

y+4-4=2x-2-4

y=2x-6

This equation is the slope intercept form.

The expression that demonstrates the associative property of multiplication is 2(24) = 2(20+4).

The correct option is D.

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

The associative property of multiplication:

a(bc) = (ab)c, where a, b, and c are the integers.

From the given choices:

2(24) = 2(20+4)

2 x 24 = 2 (24)

48 = 2 x 24

48 = 48

Therefore, 2(24) = 2(20+4) is the required expression.

Answer:

The cost of the tile for the kitchen is $1,680

Step-by-step explanation:

From the figure attached,

Dimensions of the kitchen = 5 small squares by 3 small squares

Since 1 small square = 1/4 inch

So the dimensions of the kitchen in inches = 5/4 inches by 3/4 inches

Map Scale has been given as

1 inch = 16 ft

Therefore, the actual dimensions of the kitchen will be

5/4 x 16 ft by 3/4 x 16 ft = 20 ft by 12 ft

Area of the kitchen = 20 x 12 = 240 ft²

Per square feet tile cost = $7

So the cost of tiling 240 ft² will be = 240 × 7 = $1680

Therefore, cost of the tiles for the kitchen is $1680

35 people who attended the seminar of these random samples qualifies as a representative sample if studying the opinion of the attendees to a business seminar.

What does "random sample" actually mean?

A subset of a population is chosen at random in a basic random sampling.

                This sampling technique minimizes the possibility of selection bias by giving every member of the population an exact equal probability of being chosen.

Why is a random sample important? What is it?

The use of random sampling assures that the results of your study should be close to those that would have been obtained from measurements of the complete population (Shadish et al., 2002).

                        The most basic random sample gives each unit in the population an equal probability of being chosen.

The value of the expression such that a and b are integers is 1/9

An exponential function is a mathematical function in the form y = ab^x

Given the indices expression

\(\frac{(9\frac{1}{2} )^b}{3^a}\)

This can be simplified as:

\(=\frac{(3^{2*\frac{1}{2}} )^b}{3^a}\\=\frac{3^b}{3^a}\)

According to the law of indices, the expression will becomes;

\(\frac{3^b}{3^a} =3^{b-a}\)

Recall that a - b = 2, such that b - a = -2. Substitute into the result to have:

\(\frac{3^b}{3^a} =3^{b-a}\\3^{b-a}=3^{-2}\\3^{b-a}=1/9\)

Hence the value of the expression such that a and b are integers is 1/9

To verify if the relation is a function, it must be verified if from each value of x only one arrow departs.

A relation represents a function when each input value is mapped to a single output value.

In mapping notation, with the arrows, it must be verified if there is no input from which more than one arrow departs.

Step-by-step explanation:

A rational function has a horizontal asymptote of y=0 if the degree of the numerator is less than the degree of the denominator. For example, if \(f(x)=\frac{x+1}{x^2-3}\), then there's a horizontal asymptote at y=0 because the end behavior of the function is \(f(x)\approx\frac{x}{x^2}=\frac{1}{x}\) where the outputs will approach zero.

Step-by-step explanation:

The perimeter of Sam's string is 178 inches.

Given information:

Sam has a rectangular shaped window.

Length = 65 inches.

Width = 24 inches.

To find the perimeter:

you can use the formula:

Perimeter = 2 x (Length + Width)

Substituting the values into the formula, we have:

Perimeter = 2 x (65 + 24)

Perimeter = 2 x 89

Perimeter = 178 inches

Therefore, the perimeter of the rectangular window is 178 inches.

So, the perimeter of the rectangular window is 178 inches. This means that if you were to walk along the outline of the window, you would cover a total distance of 178 inches. It's important to note that the perimeter represents the total length of all the sides combined, and it is measured in the same unit (in this case, inches) as the length and width of the window.

The probability of selecting chocolate such that:

(a) both have cherry centers: 0.1630

(b) one has a cherry center and one does not: 0.507

In this question, we have been given a box of chocolates contains 24 chocolates.

n(S) = 24

Ten of the chocolates with cherry centers.

n(A) = 10

So, the number of chocolates with no cherry centers are:

n(B) = 14

We need to find the probability of selecting chocolate such that

(a) both have cherry centers

P = (10/24)(9/23)

P = 90/552

P = 15/92

P = 0.1630

(b) one has a cherry center and one does not

P = 2*(10/24)(14/23)

P = 0.507

(a) both have cherry centers

P = 0.1630

(b) one has a cherry center and one does not

Answer:

P(x) =x³-4x²-31x+70

Step-by-step explanation:

The function is expressed as:

P(x) = (x+5)(x-2)(x-7)

P(x) =(x²-2x+5x-10)(x-7)

P(x) = (x²+3x-10)(x-7)

P(x) = x³-7x²+3x²-21x-10x+70

P(x) =x³-4x²-31x+70

Hence the polynomial is P(x) =x³-4x²-31x+70

Answer:

300 masks

Step-by-step explanation:

If 267 is 89% of the whole amount, we can set up the following proportion:

\(\frac{89}{100} =\frac{267}{x}\), where x is the total amount of masks we need to find.

If we cross-multiply, we get 26700=89x. Divide both sides by 89, and we get 300. So, Cameron has a total of 300 masks in his collection.

I hope this helped.

Answer:

300 masks

Step-by-step explanation:

89% = 0.89

( / ) = divided by

267/total amount of masks = 0.89

267/0.89 = 300

The arc cossecant of the given value is of 30º.

The cosecant of an angle is given by the ratio between 1 and the sine of the angle, as follows:

cos(x) = 1/sin(x)

The arc cossecant of an angle is represented by the expression arc csc(x), and represents the inverse of the cossecant, that is, it is the angle which has a cosecant of x.

In this problem, the arc cossecant that is asked is:

\(\arccsc{\left(\frac{2}{3\sqrt{3}}\right)}\)

Basically, it asks for the angle which has a cossecant value of 2/(3sqrt(3)). This angle is found using a calculator, and it is of 30º.

Hence the numeric value of the expression is presented as follows:

\(\arccsc{\left(\frac{2}{3\sqrt{3}}\right)} = 30^\circ\)

The probability that the first card drawn without replacement is a diamond and the second card drawn is red is approximately 0.12

The probability for an event without replacement implies that once an item is drawn, then we do not replace it back to the sample space before drawing another item.

In a standard deck of cards, there is a total of 52 cards with 13 diamonds and 26 reds (including diamonds)

probability that the first card drawn is diamond = 13/52

probability that the first card drawn is red = 25/51 {because diamond is also a red and was drawn first without replacement}

So;

probability that the first card is a diamond and the second card is red = (13/52) × (25/51)

probability that the first card is a diamond and the second card is red = 325/2652

probability that the first card is a diamond and the second card is red = 0.1225

Therefore, the proprobability that the first card drawn without replacement a diamond and the second card is red is approximately 0.12
