32. A company's profit varies directly as the number of products it sells. The company makes a
profit of $13,000 on 325 products. What is the company's profit when 999 products are sold?
This is a proportion.

Answer:

$18

Step-by-step explanation:

15 : 100 = x : 15

x =  15 · 15 / 100

x = 225 / 100

x = $ 2.25 (tips)

5 : 100 = x : 15

x = 15 · 5 / 100

x = 75 / 100

x = $ 0.75 (tax)

15 + 0.75 + 2.25 = $18

Answer: D & C

Step-by-step explanation:

The net Income of the business is represented as

Net profits or income = Net sales revenue (gross income) – Cost of goods and services sold – Administration, operating, marketing, and advertising costs, taxes, interests, and other expenses.

Here C is an option because we need to take operating expenses into consideration but if you consider cost of goods brought into store as operating then option changes to D.

D represents the sales which helps us determine the net income of the business.

After changing  the denominators to rename these fractions  the sum is 5/6 .

Given :

If necessary, use / for the fraction bar(s).

We still need to find a way to add these fractions. Now you try.

Change the denominators to rename these fractions and find their sum.

To find sum we need to find LCM of denominators .

Least common multiple :

Least Common Multiple ( LCM ) is a method to find the smallest common multiple between any two or more numbers.

so = 1 / 2 + 1 / 3

LCM of 2 and 3 is 6

= 1 * 3 + 1 * 2 / 6

= 3 + 1 * 2 / 6

= 3 + 2 / 6

Answer:

OD=Vertex: (1, -25); intercepts: x= 6,-4

Step-by-step explanation:

y=x²-2x-24

where a = 1,b = –2 and c = –24

to find the vertex we will use this formula

Step 1

(h,k) = (-b/2a, -D/4a), where D = b²–4ac.

(h,k) = (–(–2)/2×1) , –((–2)² – 4 × 1 × –24/4×1)

(h,k)= (2/2) , –(4 + 96)

(h,k) = (1 , –100/4)

(h,k) = (1,–25)

STEP 2

To find x intercept make y = 0

y=x²-2x-24

x² – 2x – 24 = 0

x² –6x + 4x – 24 = 0

x(x –6) +4(x –6) = 0

(x+4)(x–6)=0

x+4 = 0; x = –4

x–6 = 0; x = 6

x = (–4,6)

For the given circle the value of cotθ is -√30/√19.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The terminal side of an angle θ.  

The standard position intersects the unit circle at (√30/7, -√19/7).

We need to find the value of cotθ.

Suppose that θ is an angle in standard position whose terminal side intersects the unit circle at (√30/7, -√19/7)

cotθ=x/y

=-√30/7/√19/7

=-√30/7×7/√19

=-√30/√19

Hence, the value of cotθ is -√30/√19 for the given circle.

Answer:

Step-by-step explanation:

Firstly, I presume that the question talks about a rectangle and there is consistency in units i.e.Area is in units^2 and perimeter is in units (else there is no possible solution).

Now, perimeter = 2(L+B) = 40

OR (L+B) = 20.

Also, area = LxB = 100.

Now, LxB = 100 will give you the following values for LxB (Note in a rectangle, L>B or L=B):- (100×1),(50×20),(25x4),(20×5),(10×10).

Only one value gives L+B = 20 viz.L=10 & B=10.

Step-by-step explanation:

The total expected waiting time including the morning and the evening time is 41/3

given that your waiting time for a bus in the morning is uniformly distributed on [0, 8], whereas waiting time in the evening is uniformly distributed on [0, 10] independent of morning waiting time.

Sum of both waiting times = X+Y

Where X = morning wait time is U(0.8) and

Y = evening wait time is U(0,10)

Since X and Y are independent

Var(x+y) = Var(x)+Var(y)

Var(x) = (8^2 - 0^2)/12 = 16/3

Var(Y) = (10^2 - 0^2)/12 = 25/3

Var(x+y) = 16/3 + 25/3

= (16 + 25)/3

= 41/3

Therefore, the total expected value of waiting time including the morning and the evening time is 41/3.

The probability of both people being Democrats is 0.243, and the probability of one person being a Republican and one person being a Democrat is 0.486.

To find the probability of each of the following, we can use the formula for the probability of selecting a group of items from a larger group with replacement:

P(A and B) = P(A) * P(B)

Where P(A) is the probability of selecting the first item, and P(B) is the probability of selecting the second item.

Both people are Democrats:

There are 16 Democrats and 31 total people, so the probability of selecting a Democrat is 16/31. Therefore, the probability of selecting two Democrats is (16/31) * (16/31) = 0.243.

One person is a Republican and one person is a Democrat:

There are 15 Republicans and 31 total people, so the probability of selecting a Republican is 15/31. There are 16 Democrats and 31 total people, so the probability of selecting a Democrat is 16/31. Therefore, the probability of selecting one Republican and one Democrat is (15/31) * (16/31) = 0.486.

In the graph B we can see that y intercept is 9 and zero is 3. So the graph b is the correct answer.

In the given question, linear function k has a zero at 3 and a y-intercept of 9.

We have to choose which graph best represents k.

As we know that;

The link between the two unknown variables is represented by a linear equation. The linear equation have one degree.

The most basic linear equation demonstrates the relationship between (x,y), which can be used to create a table, a graph on the coordinate plane, or to perform an assessment at a particular x or y value.

We represent linear function in the form of y=mx+c.

where m is the slope of the line, c is the y intercept of the line, x is independent variable and y is the dependent variable.

As we see the y intercept in the graph crosses the y axis.

Here y intercept is 9.

The zeros of the linear function is that where y value is zero.

As in the graph B we can see that y intercept is 9 and zero is 3. So the graph b is the correct answer.

Answer:

t ≥ 5

Step-by-step explanation:

In the tank now: 19

Fill rate per minute: 6

Number of minutes: t

Amount filled in t minutes: 6t

Total amount in tank after t minutes: 6t + 19

Amount desired: at least 49 liters

At least 49 liters means "greater than or equal to 49"

Inequality:

6t + 19 ≥ 49

Subtract 19 from both sides.

6t ≥ 30

Divide both sides by 6.

The length of the side DE, that is parallel to the side AC is 6.3 units

Here the line DE is parallel to the side AC of the triangle

In the given triangle

The length of the side BD = The length of the side AD

The length of the side BE = The length of the side EC

That mean the parallel line AC is equally dividing the two side of the triangle

Therefore, the length of the line DE will be be exactly half of the line AC

The length of the side AC = 12.6 units

The length of the side DE = The length of the side AC / 2

Substitute the values in the equation

The correct order of the given statements is- 1, 2, 3, 4, 5, 6, followed by 7.

Here, we are given the following statement-

For all sets A, B and C if A ≤ B and B∩C = Φ

then A∩C = Ф

We can use the proof-by-contradiction method to prove the given statement as shown below-

Suppose that there exist 3 sets, that are- A, B, and C

Such that A ≤ B, B∩C = Φ

and A∩C ≠ Φ

Then, there must exist an element x such that x ∈ A∩C

Now, by the definition of intersection, we have- x ∈ A and x ∈ C

Then x ∈ B because A ≤ B. Additionally, we know that x ∈ C

Hence, by the definition of intersection, x ∈ B∩C

Thus, B∩C ≠ Φ by definition of null set (Φ)

But this contradicts the supposition. Hence, our assumption is false and so A∩C = Ф.

Probability is the study of numerical representations of the likelihood that an event will happen or that a statement is true. An event's probability is a number between 0 and 1, where 0 generally denotes the event's impossibility and 1 typically denotes its certainty.

Here,

a) It is irrelevant what suit the opening card is. Any of the suits may be drawn first, provided that the subsequent four cards are dealt from the same deck and are of the same suit.

After the initial card is drawn, there are only 12 of a given suit left in the deck, which has 13 of each suit in total. The third card, which has 11, the fourth card, which has 10, and the fifth and final card, which has nine, are then the cards that are still available. Each time, one fewer card will be present in the deck as a whole.

y = (-1/16)*x - 39/16

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept

If a linear equation crosses through two known points (x₁, y₁) and (x₂, y₂), then the slope of that line is given by:

a = (y₂ - y₁)/(x₂ - x₁)

And two lines are parallel if and only the two lines have the same slope and different y-intercept.

Here we want to find a line that passes through (-6, 1) and (10, 0), the slope of that line is:

a = (0 - 1)/(10 + 6) = -1/16

And we want to find a line with this slope that passes through the point (-7, -2), so we need to have:

-2 = (-1/16)*-7 + b

-2 = 7/16 + b

-2 - 7/16 = b

-32/16 - 7/16 = b

-39/16 = b
