Which graphed function is described by the given intervals? Decreasing on (−∞, 0) Increasing on (0, ∞)

Answer: The answer is 21

Answer:

2x2 matrix

Step-by-step explanation:

Given

Dimension of matrices A = 2x2 matrix

Dimension of matrices B = 2x1 matrix

The dimension of matrix AB can be gotten by cancelling the row of matrices 1 and column of matrices 2.

After cancelling both row and column, the remaining dimension will be 2x2 matrix. Hence the dimension of AB is 2x2 matrix

Answer:

1) x = 8

2) ∠RPS = 36°

Step-by-step explanation:

GIVEN :-

TO FIND :-

FACTS TO KNOW BEFORE SOLVING :-

In a straight line , if there are two angles such that their sum is equal to straight angle (or 180° in other words) , then those angles are known as linear pair.

PROCEDURE :-

1)

Measure of ∠QPS = 180° and it comprises of ∠QPR & ∠RPS.

⇒ ∠QPR & ∠RPS are linear pair.

⇒ ∠QPR + ∠RPS = 180°

⇒ 7x + 88 + 3x + 12 = 180°

⇒ 10x + 100 = 180

⇒ 10x = 180 - 100 = 80

⇒ x = 80/10 = 8

2)

x = 8. So,

∠RPS = 3×8 + 12 = 24 + 12 = 36°

Answer:

Suppose that in a given event, there are N outcomes:

{x₁, x₂, ..., xₙ}

Such that the probabilities are:

{p₁, p₂, ..., pₙ}

The expected value is:

EV = x₁*p₁ + x₂*p₂ + ... + xₙ*pₙ

In this case, we know that each ticket costs $3.

There is 1 winning ticket out of 300 tickets, where the prize is $62.

Then we have two events, the one where you win.

x₁ = $62 - $3 = $59

With a probability:

p₁ = 1/300

The one where you don't win (and still pay for the ticket):

x₂ = -$3

p₂ = 299/300

a) Then the expected value is:

EV = ( 1/300)*$59 + (299/300)*(-$3) = -$2.79

b) The expected value is additive, this means that if you buy 6 tickets, the expected value will be equal to 6 times the expected value of a single ticket.

EV = 6*(-$2.79) = -$16.74

c) For the PTO the events are:

Winner ticket, so you lose $62 and win $3 for selling the ticket.

x₁ = $3  - $62 = -$59

p₁ = 1/300

Normal ticket, you win $3.

x₂ = $3

p₂ = 299/300

In this case the expected value is:

EV = (1/300)*(-$59) + (299/300)*$3 = $2.79

d) If the PTO sells the 300 tickets, then the expected value is 300 times the expected value for a single ticket:

EV = 300*$2.79 = $837

We should have the exact same than selling the 300 tickets:

300*$3 = $900

minus the $62 for the price:

$900 - $62 = $838

There is a difference of $1, that happens because we rounded the value of the expected value (the actual one was $2.792...)

Answer:

9 x 7 = 63

6.8 x 10 = 68 divided by 2 = 34

13 + 15 = 28, 28 x  6 = 168 divided by 2 = 84

The Trapezoid.

21.6 divided by 3 = 7.2 I THINK (remember I don't really know if this is the way you learned because i dont think i've learned this)

(I split it into 2 triangles)

2 + 2 = 4

4 x 4 = 16 divided by 2 = 8

4 x 3.2 = 12.8 divided by 2 = 6.4

8 + 6.4 = 14.4

Step-by-step explanation:

Answer:

The officers can be chosen in 1320 ways.

Step-by-step explanation:

The order in which the officers are chosen is important(the first is president, second vice president and third secretary) which means that the permutations formula is used to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

In this question:

3 officers from a set of 12. So

[tex]P_{(12,9)} = \frac{12!}{9!} = 1320[/tex]

The officers can be chosen in 1320 ways.

Hi there!

[tex]\large\boxed{(-\frac{5}{3},-\frac{5}{3})}[/tex]

We can begin by setting the two expressions equal to solve for t:

2t - 1 = 5t

Subtract 2t from both sides:

-1 = 3t

Divide both sides by 3:

t = -1/3

Plug in this value of t into x(t) and y(t):

x(-1/3) = 2(-1/3) - 1 = -2/3 - 1 = -5/3

y(-1/3) = 5(-1/3) = -5/3

Thus:

(-5/3, -5/3) are the corresponding coordinates.

The image of the triangle is missing, so i have attached it.

Answer:

Option D: 8

Step-by-step explanation:

We are given;

AB = 10

AD = 25

AE = 20

We want to find length of AC.

By proportion, we can find length of AC. Thus;

AB/AD = AC/AE

Plugging in the relevant values, we have;

10/25 = AC/20

AC = (10 × 20)/25

AC = 8

Answer:

f = 119

e = 61

d = 90

Step-by-step explanation:

Answer:

Angle e is 61

Angle f is 119

Angle d is 90

Step-by-step explanation:

When two lines meet, the opposite angles are the same, so e is 61. On a straight line, there are 180 degrees, so angle f would be 180-61=119. Angle d uses the same method, the square in the bottom right tells you one side is 90, so for the other side you take 180-90, and you get 90.

Answer:

41

Step-by-step explanation:

The sum of the angles of a triangle is 180

Let the unknown angle be x

94+45+x = 180

Combine like terms

139 +x = 180

Subtract 139 from each side

139+x-139= 180-139

x =41

Answer: 41 vans will be needed.

Step-by-step explanation:

There are a total of 492 campers. We know that each van can hold a total of 12 passengers.

So, simply divide 492 by 12 to get the total amount of vans needed.

492/12 = 41 vans.

Answer:

27

Step-by-step explanation:

Evaulate 9÷3[(20-7) -2to the power of 2]

9÷3[(20-7) - 2²]

9 ÷ 3 = 3

[(20-7) - 2²] = (13 - 4) = 9

Hence ;

9÷3[(20-7) - 2²]
