Why is 0.3 a rational number A. It is on the number line.
B. The number can be written as a ratio of two integers.
C. It is a decimal.
D. The numbers can not be written as a ratio of two integers.

Answers

Answer 1

Answer:

The number 0.3 is defined as a rational number, because: B. "The number can be written as a ratio of two integers."

What is a rational number?

A rational number is a number that can be expressed as a fraction of two integers, where the denominator is not zero.

The correct answer is B. "0.3" is a rational number because it can be written as the fraction 3/10, where the numerator (3) and denominator (10) are both integers since a rational number is defined as any number that can be expressed as the quotient or ratio of two integers, with the denominator not being zero.

In this case, 0.3 can be written as the ratio 3/10, making it a rational number. Therefore, the correct answer is option B.

An employee worked 160.5 hours in may, 165.75 hours in June and 152.25 hours in july. What was the average number of hours you worked each month?

Answers

To find the average, you have to add everything up and divide by the amount that you have. In this case, you need to add together 160.5, 165.75 and 152.25, and then divide by 3.
160.5+165.75+152.25= 478.5
You've then got to divide this by three.
478.5/3= 159.5
Therefore, the average hour worked each month bu the employee is 159.5
Hope this helps :)

Determine the intercepts of the line. yy y y -intercept: (\Big( ( left parenthesis ,, , comma )\Big) ) right parenthesis xx x x -intercept: (\Big( ( left parenthesis ,, , comma )\Big) ) right parenthesis

Answers

Final answer:

To find the y and x intercepts of a line, set x and y to zero individually and solve the equation for y and x respectively. For example, in the equation y = 2x - 3, the y-intercept is (0, -3) and the x-intercept is (3/2, 0).

Explanation:

In Mathematics, when finding the intercepts of a line, we need to set y and x to zero individually and solve for x and y respectively. This will give us our x and y-intercepts. Let's say you have a line represented by the equation y = 2x - 3.

To find the y-intercept, you set x = 0 and solve for y. In that equation, if we substitute x with 0, we get y = 2*0 -3 which simplifies to y = -3. Thus, the y-intercept is (0, -3).

Similarly, to get the x-intercept, we set y = 0 and solve for x. In the equation, if we substitute y with 0, we get 0 = 2x -3. If we solve this, we find that x = 3/2. So, the x-intercept is (3/2, 0).

California has 143deaths from heart disease and 137deaths from cancer per100,000 residents. Which rate is more extreme compared to other states? A.Perform any needed computations here: b. Is California's rate for heart disease or for cancer more extreme compared to the other states? Explain:

Answers

Answer:

California's rate for heart disease is more extreme than Cancer

Step-by-step explanation:

Given

Represent Cancer with C and Heart Disease with H

H = 143

C = 137

Population = per 100,000

First we need to determine the probability of both.

For H

P(H) = H/100000

P(H) = 143/100000

P(H) = 0.00143

For C

P(C) = C/100000

P(C) = 137/100000

P(C) = 0.00137

By comparison,

0.00143 > 0.00137

So, California's rate for heart disease is more extreme than Cancer.

Reason: P(H) > P(C)

Which of Polygons B, C, D, E, and F are similar to Polygon A?

Answers

Similar polygons have congruent angles and proportional sides, which mean they have the same shape but not necessarily the same size. It's important to focus on the shapes, angles, and proportions when identifying similar polygons. Frequency polygons, though a type of polygon, are related to data representation not geometric comparison.

In order to determine which polygons are similar to Polygon A, one would need to compare the shapes and proportions of the polygons.

Similar polygons have the same shape, but not necessarily the same size. They have congruent angles and proportional sides.

This concept stems from geometry, a branch of mathematics that studies shapes and spatial relationships among different shapes.

Frequency polygons are used in data representation, and they are not directly relevant to determining similarity between geometric polygons.

They are more related to statistics, a different branch of mathematics, and are used to show the distribution of a set of data, often overlaying different data sets for comparison.

Remember, when looking for similar polygons, focus on the shapes, angles, and proportions, not the size. Without seeing the actual diagrams of Polygons B, C, D, E, and F, we cannot definitively say which are similar to Polygon A.
