Answer 2

Given vectors u = (-2,1) and v =( 4, -2) represents the vectors point in opposite directions.

What is vectors?

"Vectors is a quantity which gives us both magnitude and direction of the given quantity."

According to the question,

Given vectors u(-2,1) and v(4,-2) represented on the graph.

From the graph we conclude that given vectors u and v

Does not form obtuse angle of approximately 93° , 96° or 127°.

The vector 'u(-2,1)' is in second quadrant and v(4,-2) is in fourth quadrant.

Second quadrant and fourth quadrant are in opposite direction.

Hence, we conclude the vectors point in opposite directions.

what type of transformation is described by (x,y) —> (x+2, y+16)?

Answers

This transformation takes a vector (x,y) and maps it to the vector (x+2, y+16). In other words, it moves the X coordinate of the vector 2 units to the right, and the Y coordinate of the vector is moved 16 units upwards.

If you would take a set of points and apply this transformation, you would see the entire set moving upwards and to the right, with no stretching ou rotating. This type of transformation is called a translation transformation.

A chain letter starts when a person sends a letter to five others. Each person who receives the letter either sends it to five other people who have never received it or does not send it to anyone. Suppose that 10,000 people send out the letter before the chain ends and that no one receives more than one letter. How many people receive the letter, and how many do not send it out?

Answers

Answer:

50,001 people sent out the letter.

40,001 did not send it out

also can i get brainliest???

Step-by-step explanation:

780 people receive the letter before the chain ends.

9,220 people do not send out the letter.

We have,

In the given scenario, the chain letter starts with one person sending it to five others.

Each recipient of the letter has the option to either send it to five new recipients or not send it to anyone.

Let's analyze the chain letter progression:

The first person sends the letter to 5 recipients.

Each of those 5 recipients has the choice to send the letter to 5 new recipients or not send it.

If each of the 5 recipients sends the letter to 5 new recipients, we have a total of 5 x 5 = 25 new recipients.\

If any of the 5 recipients choose not to send the letter, they are out of the chain.

Now, we have 25 recipients who received the letter and have the same choice: send it to 5 new recipients or not send it.

If each of the 25 recipients sends the letter to 5 new recipients, we have a total of 25 * 5 = 125 new recipients.

If any of the 25 recipients choose not to send the letter, they are out of the chain.

This process continues until the chain ends.

To determine how many people receive the letter and how many do not send it out, we can observe the pattern:

After the first step, there are 5 recipients.

After the second step, there are 5 + (5 * 5) = 30 recipients.

After the third step, there are 5 + (5 * 5) + (5 * 5 * 5) = 155 recipients.

After the fourth step, there are 5 + (5 * 5) + (5 * 5 * 5) + (5 * 5 * 5 * 5) = 780 recipients.

We can see that the number of recipients follows a geometric progression with a common ratio of 5.

The formula for the sum of a geometric progression is:

[tex]Sum = a (r^n - 1) / (r - 1)[/tex]

Where:

a = initial term = 5

r = common ratio = 5

n = number of steps

We are given that the chain ends after 10,000 people send out the letter. Let's calculate the number of recipients:

[tex]Sum = 5 (5^4 - 1) / (5 - 1)[/tex]

= 5 (625 - 1) / 4

= 5 624 / 4

= 780

Therefore, 780 people receive the letter before the chain ends.

To find the number of people who do not send it out, we subtract the number of recipients from the total number of people who sent out the letter:

Number of people who do not send it out = Total number of people - Number of recipients

= 10,000 - 780

= 9,220

Therefore, 9,220 people do not send out the letter.

Thus,

780 people receive the letter before the chain ends.

9,220 people do not send out the letter.

We need to complete the grouped frequency distribution for the data.

What is the grouped frequency distribution?

In this type, the data is arranged and separated into groups called class intervals. The frequency of data belonging to each class interval is noted in a frequency distribution table. The grouped frequency table shows the distribution of frequencies in class intervals.

Now, the frequency distribution for the given intervals is as follows:

That is, for intervals 1 to 5 the frequency is 2.

For intervals 5 to 10 the frequency is 4.

For intervals 11 to 15 the frequency is 2.

For intervals 16 to 20 the frequency is 2.

Therefore, the grouped frequency distribution for the data with the given intervals is 2, 4, 2 and 2 respectively.

The probability that a randomly chosen college student exercises in the morning or afternoon are 0.37.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

From the given Venn diagram, we see that

Probability that the student exercises in the afternoon

P(A) = 0.14 + 0.37 = 0.51

Probability that the student exercises in the morning

P(M) = 0.25 + 0.37 = 0.61
