3.5 as a mixed number.

Answer:

Domain and Range in set notation

Domain: {x|x=4,0,-2}

Range: {x|x=-1,4,9,-9}

Step-by-step explanation:

We are given a relation G

G={(4,-1),(0,4),(-2,9),(-2,-9)}

We need to find domain and range of the relation G

Domain: The domain is the set of all first elements of ordered pairs (x-coordinates)

Range: The range is the set of all second elements of ordered pairs (y-coordinates).

So for the given relation G={(4,-1),(0,4),(-2,9),(-2,-9)}

Domain is: (4,0,-2)

Range is: (-1,4,9,-9)

So, Now writing Domain and Range in set notation

Domain: {x|x=4,0,-2}

Range: {x|x=-1,4,9,-9}

Answer: А. On average, the number of students going to an office hour varies from the mean by about 2.2 students

Step-by-step explanation:

The standard deviation is a measure of spread, which gives how values deviate from the average or mean value of a particular distribution. Hence, the standard deviation is usually defined about the average value of a distribution.

Therefore, for a certain random variable representing the number of student who visits office hours, the standard deviation will be defined about the average or mean value of the random variable Q.

Thus, stated as ; number of students going to an office hour varies from the mean by 2.2 on average.

Concept: Mathematical Modeling

The equation which represents Kendra's profit P(n) will be  P(n) = 0.55n.

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.

Given,

Profit was $55 by selling 100 donuts

Profit per donuts = 55/100 = $0.55

Let's say she sold n number of donuts

Then.

Profit P(n) = 0.55n.

Hence "Kendra's profit P(n) will be  P(n) = 0.55n".

Answer:

$513.5

Step-by-step explanation:

$475 + ($700 x 5.5 / 100)

$475 + ($3850 / 100)

$475 + $38.5

$513.5

Answer:

1. b = 47

2. c = 18

Step-by-step explanation:

From the question given above, we can see that the two shapes are right angle triangle.

Thus, if ΔUVW ≅ ΔFED, then

1. VW = ED

2. UW = FD

3. UV = EF

1. Determination of the value of b.

UW = 47

FD = b

UW = FD

47 = b

Therefore,

b = 47

2. Determination of the value of c.

VW = c

ED = 18

VW = ED

c = 18

Answer:

G

Step-by-step explanation:

Answer:

y=1/3x

When x of the line is -3, y of the line must be -1.When x of the line is 6, y of the line must be 2. y=1/3x+b. b is what we want, the 1/3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specifically passes through the two points (-3,-1) and (6,2).(-3,-1). y=mx+b or -1=1/3 × -3+b, or solving for b: b=-1-(1/3)(-3). b=0.b came out to be zero, so there is no "+b" term.

Answer:

8=w, -8=w  (±8=w)

Step-by-step explanation:

192=[tex]3w^{2}[/tex]

First, divide by 3

64=w²

now take the square roots of 64 and w² ( we're thinking about which numbers/variables will be multiplied to get 64 and w². They are 8 and w. But wait! -8 can also work, since when you square it a negative number, it will turn positive. )

8=w, -8=w

You can also write it as ±8=w

Hope this helps!

Answer:

The constant of proportionality is 5

Step-by-step explanation:

Given

[tex]y = \$30[/tex] --- Cost

[tex]x = 6[/tex] --- Number of shirts

Required

Determine the constant of proportionality

The relationship between y and x is:

[tex]y =kx[/tex]

Where:

k = constant of proportionality

Substitute [tex]30\ for\ y[/tex] and [tex]6\ for\ x[/tex]

[tex]30 = k * 6[/tex]

[tex]30 = 6k[/tex]

Divide both sides by 6

[tex]\frac{30}{6} = \frac{6k}{6}[/tex]

[tex]\frac{30}{6} = k[/tex]

[tex]5 = k[/tex]

[tex]k = 5[/tex]

The constant of proportionality is 5

Answer:

lets call andere A and diego D.

so

A-9=D

D times 2 = n

now we divide 10/2 and thats 5

diego scored 5 points so we can sub in

A-9=5

now we add 9. making 14

ANDRE SCORED 14

Answer:

Diego scored 14 points

x = 14

Answer:

P=(-4/5,34/5)

Step-by-step explanation:

P=2/5{(-8+6),(-2+19)}

P=2/5{-2,17}

P={-4/5,34/5}

Answer:

$56

Step-by-step explanation:

The jacket is on sales for 30% off the original price = (0.3)

The original price (P) = $80

However, the expression "p - 0.3p" is to be used to find the sales price

The sale price = p - 0.3p

The sale price = $80 - 0.3($80)

The sale price = $80 - $24

The sale price = $56

Answer:

the answer is A because anything with an exponent of 0 is = to 1

Answer:

(1/5, 9/5)

Step-by-step explanation:

Given the set of inequities

x+y>2..... 1

4x-y≥-1 .... 2

We are to get the solution point (x,y)

Solving simultaneously

From 1:

x>2-y

Substitute into 2

4(2-y)-y≥-1

4(2)-4y-y≥-1

8-5y≥-1

-5u ≥-1-8

-5y ≥-9

y≤9/5

Since x>2-y

x>2 - 9/5

x>1/5

Hence the required point is (x,y) = (1/5, 9/5)

Answer:

C. (0,3)
