x and y are two integers and x ≠ 0. Which of the following is not a rational number? a) z b) y c)x/y d) y/x​

Answers

Answer 1

Answer: Choice A) z

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

Explanation:

x and y are two integers, with x being nonzero

This means x/y is rational as long as y is nonzero as well. If y = 0, then we have a division by zero error. Try something like 1/0 on your calculator and you'll find it doesn't work.

Similarly, y/x is rational as well. Any rational number is simply dividing two integers as a fraction like this. Other examples include stuff like 1/2, 4/5, 8/17, and so on.

Since y is an integer, this means we can write it like this: y = y/1. This shows any integer is also rational, but not the other way around. A fraction like 2/3 is rational but not an integer.

All of what was discussed above indicates that choices B, C and D can be ruled out. The only thing left is choice A. The variable z isn't defined, so it's not clear what it is exactly. But it's likely the answer as it's the only thing left after the eliminations.

Melanie volunteers on the weekend at the Central Library. As a school project, she decides to record how many people visit the library, and where they go. On Saturday, 467 people went to The Youth Wing, 433 people went to Social Issues, and 342 went to Fiction and Literature.On Sunday, the library had 1500 total visitors. Based on what Melanie had recorded on Saturday, about how many people should be expected to go to Fiction and Literature? Round your answer to the nearest whole number.

Answers

Answer:

413 people should be expected to go to Fiction and Literature

Step-by-step explanation:

Proportion of people who went to Fictions and Literature on Saturday:

342 out of 467 + 433 + 343 = 1243

The proportion is:

342/1243 = 0.275

On Sunday:

Based on Saturday, so 0.275 out of 1500(number of visitors on Sunday).

0.275*1500 = 412.5

Rounding to the nearest whole number:

413 people should be expected to go to Fiction and Literature

Angle Relationships

When solving for x, the sine of 44° is used. What other angle and trigonometric function could be used to solve for x?

a. tan 46°
b. cos 46°
c. tan 44°
d. cos 44°

Please select the best answer from choices provided

Answers

Answer:

B. cos 46°

Step-by-step explanation:

I calculated it logically

Answer:

b. cos 46

Step-by-step explanation:

There are three angles to choose from since there are three angles in a triangle. Of these, the 90° angle can't be used (90° angles don't work with trigonometric ratios), and neither can the 44° (we're told to use a different one from this), so we're left with the unmarked angle on the bottom right. Since the angles in a triangle add to 180, and the other two angles total 134 (90+44=134), we can say this angle is 46°.

Since cos46 is our only option that involves this angle (and since cos46=x/9), this is the option which could be used to find x.

Find the probability of getting heads 2 times in a row, then rolling a 6 sided die and getting
either a 1 or 6.

Answers

Answer:

1/12

Step-by-step explanation:

The probability of rolling a die and landing it on heads is 1/2 percent. Flipping the coin another time and landing it on heads is 1/4 percent because you need to multiply when doing probabilities, so 1/2 times 1/2 equals 1/4.

Now moving on, rolling a 6 sided die and getting either a 1 or 6 is 1/3 percent because 1 and 6 are two different numbers you can roll so it's 2/6, and when it's simplified, it's 1/3.

After doing that, to find the probability of the whole equation, you would need to multiply 1/4 times 1/3 which would give you 1/12 as your answer.

A package of colored paper contains 20 pieces of yellow paper. This represents 25% of the total pieces of colored paper in the package. 6.RP.3c Part A. Write 25% as a rate per 100 in simplest form. How many total pieces of colored paper are in the package?

Answers

Answer:

There were 80 pieces of colored paper in the package.

Step-by-step explanation:

Given that a package of colored paper contains 20 pieces of yellow paper, and this represents 25% of the total pieces of colored paper in the package, to determine how many total pieces of colored paper are in the package, the following calculation must be performed:

25 = 20

100 = X

100 x 20/25 = X

2,000 / 25 = X

80 = X

Therefore, there were 80 pieces of colored paper in the package.

Answers

Answer:

361,899

hope this helps

Answer:

350,000

Step-by-step explanation:

1,500,000 - 1,138, 101 = 361,899

361,899 - 350,000 = 11,899

400,000 - 361,899 = 38,101

11,899 is less than 38,101

So, 350,000 is the answer.

What is data distribution?

The data distribution is a way to represent the values of a set of data or information. The distribution of data is generally represented in a particular order.

In the given graph, the data distribution is shown for the coin toss. The probability P(X) is shown on the y-axis of the graph, and the number of heads is shown on the x-axis.

There are two types of data distribution shown on the graph.

Symmetric - The data distribution shown on the graph is symmetric over x = 1.

Discrete - The data distribution shown on the graph is discrete because the values of X are distinct.

Hence, the type of data distribution which is shown on the graph of coin toss where, x is the number of heads is symmetric and discrete.
