According to a Pew Research Center study, 14% of Americans have changed their views on a political or social topic in the last year because of something they saw on social media. Let the random variable be the number of people, from a random sample of 60 Americans, who have changed their political or social views in the last year because of social media.
Is the number of these people who have changed their views because of social media a binomial random variable?
A. Yes. All four conditions are met.
B. No. There is not a fixed number of trials.
C. No. The trials cannot reasonably be assumed to be independent.
D. No. The outcomes cannot be described as only "success" and failure"
E. No. The probability of success is not the same for each trial.

Answers

Answer 1

Answer:

A. Yes. All four conditions are met.

Step-by-step explanation:

Binomial random variable:

Can only have two outcomes(yes/no questions).

Each trial must be independent, that is, the probability of a success is always the same in a trial.

It's probabilities must be between 0 and 1.

Number of these people who have changed their views because of social media a binomial random variable.

For each people, there are only two possible outcomes. Either they did change, or they did not. For each people, the probability of changing is independent of other people, that is, the probability is the same, so yes, the conditions are met.

Answers

Given :

M(6,5) is the mid-point of the straight line joining A(2 , 3) to the

point B.

To Find :

The coordinates of B.

Solution :

Let, coordinates of point B is ( h , k ) .

It is given that M is the mid - point of the straight line joining points A and B.

Coordinates of M is given by :

[tex]M = (\dfrac{2+h}{2},\dfrac{3+k}{2})\\\\(6,5 ) = (\dfrac{2+h}{2},\dfrac{3+k}{2})\\\\\dfrac{2+h}{2} = 6 \ , \ \dfrac{3+k}{2} = 5\\\\h = 10 \ ,\ k = 7[/tex]

Therefore, coordinates of point B is ( 10 , 7 ).

Answer:

885.18

Step-by-step explanation:

Base = 18x18=324

triangles = 1/2(18)height

To find the height, you could divide it in half and use the 30-60-90 rule or Pythagorean theorem.

9²+b²=18²

81+b²=324

b²=324-81

b²=243

b=√243

b=15.58

So each triangle is 1/2(18)(15.58845)=140.2961.

Four of them would be 561.1845.

Now add the base.

561.1845+324=885.1844

Answers

Answer:

c must be less than 10 but greater than 4.

Step-by-step explanation:

In order to solve this problem, you have to apply the triangle inequality theorem. This theorem is used to determine whether or not you can form a triangle. According to the theorem, the sum of the two sides must be greater than the longest side of the triangle.

For instance, a triangle has side lengths 4, 5, and 7.

Can you form a triangle with these values?

Well, let's see

Since 4 and 5 are values less than 7, you are going to be adding those numbers. 4 plus 5 is 9. 9 is greater than 7. This means that you can form a triangle with those numbers.

For this question, you are given a triangle that has the side lengths of 3 inches, 7 inches, and c inches. The question wants the range of values. Make c the shortest side and the longest side.

Let's start with longest first.

take 3 and 7

Add them and you will get 10.

10 is greater than c. or c<10.

For the shortest side make 7 the longest

3 plus c is less than 7

subtract 3 from both sides

then you get c is less than 4. or c<4.

So you have c<4 and c>10.

combine them to make a long inequality.

4<c<10.

That is your answer.

What’s 8367 divided by 7

Answers

Answer:

1195.28

Step-by-step explanation:

We have a division problem which is 8,367 ÷ 7.

When it comes to division, you always look at the first number that is being split equally by the second number.

Follow the steps of the division problem :

Find how many times 7 goes into 8 :

7 * 1 = 7

Subtract 7 from 8 :

8 - 7

1

We have 1 in our thousands place, move down the number next to 8 in 8367 which is 3, and see how many times 7 goes into that number :

13

7 * 1 = 7

Therefore 7 only goes in once, put 1 next to 1 on top of the division problem, subtract 7 from 13 :

13 - 7

6

Move the 6 down from 8367 and see how many times 7 goes into that :

7 * 9 = 63

Subtract 63 from 66 :

3

Put 9 next to the one, as for now we have 119, now bring down the last value in 8367 and see how many times 7 goes into that :

37

7 * 5

35

Subtract 37 - 35 :

2

Therefore, our answer is 1195.28 , 1195 Remainder 2

Answer: The answer to 8367 divided by 7 equals 1195.285714 It can also be writtin as 1195.28 for short

Step-by-step explanation: The result of 8367/7 is a non-terminating, repeating decimal. The repeating pattern above, 285714, is called repetend, and denoted overlined with a vinculum.

This notation in parentheses is also common: 8367/7 = 1195.(285714): However, in daily use it’s likely you come across the reptend indicated as ellipsis: 8367 / 7 = 1195.285714… .

8367 divided by 7 in decimal = 1195.285714

8367 divided by 7 in fraction = 8367 divided 7

8367 divided by 7 in percentage = 119528.57142857%

Answers

Given:

The reasoning problem is

42=164, 73=499, 51= 251, 29=?

To find:

The missing value.

Solution:

In the given reasoning problem, we need to square each digit then write them combinedly.

[tex]4^2=16[/tex]

[tex]2^2=4[/tex]

On combining these two, we get

[tex]42=164[/tex]

Similarly,

[tex]73=7^23^2=499[/tex]

[tex]51=5^21^2=251[/tex]

Using this pattern, we need write the square of 2 and 9 combinedly to find the value of 29.

[tex]29=2^29^2=481[/tex]

Therefore, the missing value is 481.

Ana can swim at a rate of 3/8 mile in 1/3 hour how many minutes would it take her to swim 1 mile at this rate round your answer to the nearest Minute

Answers

ANSWER: 53 minutes


First, find what 1/3 of an hour equals in minutes. 20 minutes = 1/3 hour

Second, the goal is to find how many minutes it takes Ana to swim 1 mile, so you want to find how long it takes Ana to swim 1/8 of a mile.
3/8 mile = 20 minutes
20/3 = 6.666... so 1/8 mile = 6.666... minutes

Third, multiply the amount of time it takes to swim 1/8 mile by 8.
6.666 x 8 = 53.328 ⬅️ round to the nearest minute = 53 minutes

What is Algebra?

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Twenty-one is greater than the sum of fifteen and two times a number​

let the number be x.

two times a number​ = 2x

and, sum of fifteen and two times a number​ = 15 + 2x

So, Twenty-one is greater than the sum of fifteen and two times a number​

21 > 15+ 2x

Hence, the expression is 21 > 15+ 2x.
