A.10%
B.25%
C.50%
D.75%

50% I know I did this before

Answer: C

Step-by-step explanation:

Because 8 + 2 = 10 and that is half and blue is the other half so it’s 50%

The population of Gilbert increased 275%. Which of the following are equivalent to 275%?

It’s 27 1/2 which is the 3rd one

The 2 3/4 or 2.75 is equivalent to 275%.

What is Percentage?

The percentage formula is used to calculate the amount or percentage of anything in terms of 100. Percentage indicates "per hundred" in its most basic form. The percentage formula is used to express a number between zero and one. It is a number that is expressed as a fraction of 100. It is represented by the sign% and is mostly used to compare and find ratios.

The population of Gilbert increased by 275%. The equivalent to 275% will be:

To express as fraction and decimal, we divide 275 by 100.

= 275/100

= 2 3/4

= 2 + 0.75

= 2.75

So, the equivalent fraction is 275% = 2 3/4 or 2.75.

cos= -1/2

tan= square root 3

csc= -2 square root 3/2

sec= -2

cot= square root3/4

Answer:

[tex]\sin\left(\frac{4\pi}{3}\right)=-\frac{\sqrt{3}}{2}\\\cos\left(\frac{4\pi}{3}\right)=-\frac{1}{2}\\\tan\left(\frac{4\pi}{3}\right)=\sqrt{3}\\\csc\left(\frac{4\pi}{3}\right)=-\frac{2\sqrt{3}}{3}\\\sec\left(\frac{4\pi}{3}\right)=-2\\\cot\left(\frac{4\pi}{3}\right)=\frac{\sqrt{3}}{3}[/tex]

Consider a single spin of the spinner.


Which events are mutually exclusive? Choose all that apply.


a

landing on an unshaded sector and landing on a number less than 2

b

landing on a shaded sector and landing on a 3

c

landing on an unshaded portion and landing on an odd number

d

landing on a shaded sector and landing on an even number

e

landing on a shaded sector and landing on a number greater than 3

Answers

The question is incomplete

Find attached to the question, the appropriate diagram

Answer:

a) landing on an unshaded sector and landing on a number less than 2

b) landing on a shaded sector and landing on a 3

Step-by-step explanation:

Mutually exclusive events are two events that can occur separately on their own but they cannot occur together or at the same time.

The options given are explained below:

We have two shaded sectors: 1 and 4

We have two unshaded sectors : 2 and 3

a) landing on an unshaded sector and landing on a number less than 2

Looking at option a, we find out that it is possible for the spinners to land on an unshaded sector separately likewise on a number less than 2 but it cannot land on an unshaded sector AND and number less than 2 because looking at the spinner, the numbers on the unshaded sectors are 2 ( is equal to two) and 3 ( which is above 2).

Therefore this option is mutually exclusive and correct.

b) landing on a shaded sector and landing on a 3

It is possible to land on a shaded sector likewise it is possible to land on a 3 but it is not possible to land on a shaded sector and land on a 3 at the same time.

This is because, the number on the shaded sector is 1 and 4 and the number on the unshaded sector is 2 and 3, we have only one spinner so the spinner can only land on one sector at a time.

Therefore, Option b is a mutually exclusive event and it is a correct option.

c) landing on an unshaded portion and landing on an odd number

The unshaded portion on the spinner has number 2 and 3 on them, therefore it is possible to land on an unshaded portion and odd number which is 3 at the same time.

Option c is not a mutually inclusive event and it is wrong.

d) landing on a shaded sector and landing on an even number

The shaded sector on the spinner has number 1 and 4 on them, therefore it is possible to land on an shaded sector and even number which is 4 at the same time.

Option d is not a mutually inclusive event and it is wrong.

e)landing on a shaded sector and landing on a number greater than 3

The shaded sector on the spinner has number 1 and 4 on them, therefore it is possible to land on an shaded sector and a number greater than 3 which is 4 at the same time.

Option e is not a mutually inclusive event and it is wrong.

Therefore, option a and option b are mutually exclusive events and they are correct.

Answer:

a.  landing on an unshaded sector and landing on a number less than 2

e  landing on a shaded sector and landing on a number greater than 3

Step-by-step explanation:

Two events ; for example events A and B are said to be mutually exclusive , if they cannot both occur simultaneously.In set theoretical notation , we say that the two sets A and B are disjoint set.

i.e

A ∩ B = ∅

Pr (A ∩ B) = 0

The intersection of A and B is an empty set and as such there is no intersection.

From the given options; option a and e are correct because ;

a.

landing on an unshaded sector and landing on a number less than 2

Landing on an unshaded portion would 2 or 3.

Landing on a number less than 2 would be 1.

There is no intersection and as such these events are mutually exclusive.

e.

landing on a shaded sector and landing on a number greater than 3

Landing on a shaded portion would be 1 or 4.

Landing on a number greater than 3 would be just 4.

The intersection of both events will be an empty set (∅)

As such these events are not mutually exclusive.

A cube is a rectangular prism with the same measurement for length, width and height. If a cube is 6
inches tall, what is its volume?

Answers

Answer:

216 inches cubed

Step-by-step explanation:

To find the volume you need length times width times height. Since it is a cube it would be 6 inches * 6 inches * 6 inches which is 216 inches cubed.

Volume of the cube is 216 cubic inch

What is Cube?

A cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex

What is Rectangular prism?

A rectangular prism is a 3D figure with 6 rectangular faces

What is Volume?

Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface

Given,

A cube is a rectangular prism with the same measurement for length, width and height

Height of the cube h= 6 inches

Length of the cube l= 6 inches

Width of the cube w= 6 inches

Volume of the cube = l× w × h

Volume of the cube = 6×6×6 =216 cubic inch

Hence the volume of  cube is 216  cubic inch

Suppose matrix D is the inverse of matrix C. Which of the following is equal to D?
O CDD
O CCD
O DDD
O CCC

Answers

Answer is First answer choice: CDD

==========================================

Explanation:

C and D are inverses of each other. When they multiply together, they will produce the identity matrix I

C*D = I

D*C = I

note: this is the uppercase letter 'i' and not the number one. The 'i' stands for 'identity'. Another thing to note is that matrix multiplication is not normally commutative, but it works for matrix inverses.

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

So this means C*D*D = (C*D)*D = (I)*D = I*D = D because multiplying the identity matrix with some matrix X leads to the same matrix X.

This is why the first choice is the answer.

The second choice doesn't work because C*C*D = C*(C*D) = C*(I) = C*I = C

The third choice doesn't work because we don't have any C's here. All we can say is that D*D*D = D^3

Similarly choice 4 doesn't work as all we can say is C*C*C = C^3.

Rounded to the nearest hundredths 27.5=3+5(k-9.5)

Answers

Answer:

12 = k

Step-by-step explanation:

Begin: 27.5 = 3 + 5 (k-9.5)

1. Always begin with the parenthesis, which is 5(k-9.5), which comes out to be 5k - 47.5 since the 5 must be multiplied by the k and the -9.5.

Now: 27.5 = 3 + 5k - 47.5

2. Combine the 3 and -47.5, which comes to be -44.5

Now: 27.5 = -44.5 + 5k

3. Add 44.5 to both sides, to make the right side have only the 5k, and the left side to have 72

27.5 + 44.5 = -44.5 + 44.5 + 5k

Now: 72 = 5k

4. Divide both sides by 5 to be left with just what k equals

72/5 = 5k/5

Final Answer: 12 = k
