Answer:

C (3rd choice)

Step-by-step explanation:

Domain (x-values):

We can see that there is a max number of 14 hours and a min. of 0 hours. This means that the domain is [0, 14]. Note that the domain would be in brackets (as opposed to parentheses) because the values are included in the data set. Since time works on a continuum, it can be reasonably concluded that all values should be included (e.g., 1.5 hours exists). Therefore, we would state that all numbers from 0 to 14 are valid in the domain.

Range (y-values):

We can see that there is a max of 85 people and a min. of 0 people. This means that the range is [0, 85]. Again, since the values 0 and 85 are both included in the data, the range is notated in brackets. Be mindful that there is no such thing as half person, so the range must only include whole numbers. That means this chart acts as a step-function.

Answer:

$19.99

Step-by-step explanation:

There are 12 months in a year, so in 2 years, there are 24 months.

Find how much each payment will be by dividing the cost by 24:

479.76/24

= 19.99

So, each payment will be $19.99

Answer:

8 17/18

Step-by-step explanation:

3 5/6 + 5 1/9

23/6 + 46/9

161/18

8 17/18

Given:

y varies directly with x,

It is given that y = 7 when x = -9.

To find:

The value of y when x = 27 for the direct variation.

Solution:

It is given that y varies directly with x, so

[tex]y\propto x[/tex]

[tex]y=kx[/tex]             ...(i)

Where, k is the constant of proportionality.

It is given that y = 7 when x = -9. Putting these values in (i), we get

[tex]7=k(-9)[/tex]

[tex]-\dfrac{7}{9}=k[/tex]

Putting [tex]k=-\dfrac{7}{9}[/tex] in (i), we get

[tex]y=-\dfrac{7}{9}x[/tex]

Putting [tex]x=27[/tex],  we get

[tex]y=-\dfrac{7}{9}(27)[/tex]

[tex]y=-21[/tex]

Therefore, the required value is [tex]y=-21[/tex].

Answer: 489

Step-by-step explanation:

420+69=489

Answer:

x = (k-14)/5

Step-by-step explanation:

5x + 14 = k

Subtract 14 from each side

5x + 14-14 = k-14

5x = k-14

Divide by 5

5x/5 = (k-14)/5

x = (k-14)/5

Answer:

k - 14/5

Step-by-step explanation:

5x + 14 = k

On subtracting 14 on both sides,

5x = k - 14

On dividing by 5 on both sides,

x = k - 14/5

Therefore, the value of x = k-14/5

Answer:

66.7%

Step-by-step explanation:

Please find attached the complete question

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

probability that a randomly selected point within the circle falls in the white area = degree occupied by white area / sum of angles in a circle

sum of angles in a circle = 360

degree occupied by white area = sum of angles in a circle - sum of degrees of shaded area

360 - (60 + 60) = 240

240 / 360

convert to its simplest form by dividing by 120 = 2/3

2/3 x 100 = 66.7%

perimeter of rectangle=a+b+c

=3x+3x+15

=6x+15

if perimeter of rectangle is 90,

perimeter=a+b+c

90=3x+3x+15

90-15=6x

75/6=x

12.5=x

Answer:

X=12.5

Step-by-step explanation:

3x+3x+15

If it equalls 90 then write it as 6x+15=90

Now isolate X.

6x+15=90

6x=75

x=12.5

CHECK UR WORK

(3*12.5)+(3*12.5)+15=90

37.5+37.5+15=90

75+15=90

Answer:

14.583333% decrease

Step-by-step explanation:

First find the difference

24000-20500 =3500

Then divide by the original amount

3500/24000 =.14583333

Change to a percent

14.583333% decrease

Answer:

14.6%

Step-by-step explanation:

Use the ol’ reliable: [tex]\frac{new(value)-old(value)}{old(value)}*100[/tex]

In this case: [tex]\frac{20500-24000}{24000}*100=-14.6[/tex]

It’s a 14.6% decrease.

Answer:

2^(2/5) * 2^½ => first option

Step-by-step explanation:

^5√4 * √2 = ^5√2² * √2

= 2^(2/5) * 2^½ => first option

The expression can be written as [tex](4)^\frac{1}{5}\times(2)^\frac{1}{2}[/tex]. The correct option is C.

The symbol " that expresses a number's root is known as radical, and it is read as x radical n or the nth root of x. The horizontal line that surrounds the number is known as the vinculum, and the number beneath it is known as the radicand. The index or degree is the number n written before the radical.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is ⁵√4 x√2. The expression can be written as:-

E =  ⁵√4 x√2

Answer:

g(x) = 0.5x²

Step-by-step explanation:

Since the graph of g(x) still passes through the origin and is u shaped, it is also a quadratic graph but with a different coefficient of x².

Let g(x) = ax²

When x=2, g(x) = 1

Hence, 2a = 1

a = 0.5

Therefore, g(x) = 0.5x²

Answer:

eliminate D

Step-by-step explanation:

Answer:

Multiply the first equation by 15 (Answer D)

Step-by-step explanation:

Writing these equations symbolically, we have:

(2/3)x + (1/5)y = 6

(1/6)x - 3y = 8

Which number can she multiply the first equation by so that when the two equations are added together, the y term is eliminated?  After this multiplication, we should have +3y in the first equation; then 3y - 3y = 0 as desired.  The coefficient of the y term in the first equation is (1/5), whereas we want it to be +3.  

Multiplying the first equation by 15, we get 10x + 3y = 90.

Then our system is:

10x + 3y = 90

(1/6)x - 3y = 8

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

(61/6)x = 98    (the variable y has been temporarily eliminated).

Answer:

The total discount is 51%.

Step-by-step explanation:

A 30% discount is applied to the price of a product and another 30% discount to the new price. What is the total discount?

Let the price is p.

After first discount, the price is

= 70% of p = 0.7 p

After second discount, the price is

= 70% of 0.7 p

= 0.7 x 0.7 p

= 0.49 p

So, let the total discount is d.

[tex]d = \frac{p - 0.49 p}{p}\times 100 = 51%[/tex]

Step-by-step explanation:

Answer:

Angle-side-angle is a rule used to prove whether a given set of triangles are congruent.

The ASA rule states that:

If two angles and the included side of one triangle are equal to two angles and included side of another triangle, then the triangles are congruent.

Angle-Angle-Side (AAS) Rule

Angle-side-angle is a rule used to prove whether a given set of triangles are congruent.

The AAS rule states that:

If two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle, then the triangles are congruent.

In the diagrams below, if AC = QP, angle A = angle Q, and angle B = angle R, then triangle ABC is congruent to triangle QRP.
