The chance that you will get a heads or tails when you flip a coin once (option A) is not mutually exclusive.

Mutually exclusive events are events that cannot occur at the same time, or that do not have any overlap. In the case of flipping a coin, the possibility of getting a head and the possibility of getting tails are independent of each other, and both can occur simultaneously. Therefore, the chance that you will get heads or tails when you flip a coin once is not mutually exclusive.

On the other hand, the other events listed (B, C, and D) are mutually exclusive. The chance that you will only study for the test alone or with a friend cannot occur simultaneously, as you can either study alone or with a friend, but not both. Similarly, the chance that you will meet your friends for pizza or at a Chinese restaurant for dinner today at 6 cannot occur at the same time, as you can either go to the pizza place or the Chinese restaurant, but not both. And the chance that you will answer the ringing phone or take a walk cannot occur simultaneously, as you can either answer the phone or take a walk, but not both.

The chance that you will get a heads or tails when you flip a coin once (option A) is not mutually exclusive.

this question is related to probability.

mutually exclusive

Mutually exclusive events are those events that do not occur at the same time.

For example, when a coin is tossed then the result will be either head or tail, but we cannot get both the results. Such events are also called disjoint events since they do not happen simultaneously.

probability

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

Answer:

\(|\frac{x}{y} |\)

Step-by-step explanation:

We are given the following expression: \(\sqrt\frac{x^3y^5}{xy^7}\), where x > 0 and y > 0.

We want to simplify it.

To do that, we can first simplify what is under the radical, then take the square root of what is left.

Recall that when simplifying exponents, we don't want any negative or non-integer radicals left.

To simplify what is under the radical, we can remember the rule where \(\frac{a^n}{a^m} = a^{n-m}\).

So, that means that \(\frac{x^3}{x} = x^2\) and \(\frac{y^5}{y^7} = y^{-2}\) .

Under the radical, we now have:

\(\sqrt{x^2y^{-2}}\)

Now, we take the square root of both exponents to get:

\(|xy^{-1}|\)

The reason why we need the absolute value signs is because we know that x > 0 and y > 0, but when we take the square root of of \(x^2\) and \(y^{-2}\) , the values of x and y can be either positive or negative, so by taking the absolute value, we ensure that the value is positive.

However, we aren't done yet; remember that we don't want any radicals to be negative, and the integer of y is negative.

Recall that if \(a^{-n}\), that is equal to \(\frac{1}{a^n}\).

So, by using that,

\(|x * \frac{1}{y} |\)

This can be simplified to:

\(|\frac{x}{y} |\)

Convert quarts to cups:

Total quantity of soup served = Number of people in Kimberly's family × Volume of bowl

= 4 × 2

= 8 cups

Quantity of bowls of soup are left in the pot = Quantity of chicken noodle soup made - Total quantity of soup served

= 24 cups - 8 cups

The measure of the angle formed by the plane's path and the road from city J to city K is approximately 57.2 degrees.

To find the measure of the angle formed by the plane's path and the road from city J to city K, we can use the trigonometric concept of tangent.

In right triangle JKL, the tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.

In this case, we are interested in finding the angle formed by the plane's path and the road from city J to city K. Let's denote this angle as θ.

The tangent of angle θ can be calculated as:

tan(θ) = Opposite / Adjacent

Using the given information, the opposite side is KL with a length of 15.1 miles, and the adjacent side is LJ with a length of 9.4 miles.

tan(θ) = 15.1 / 9.4

Using a calculator or approximation, we find:

tan(θ) ≈ 1.60638

To find the measure of angle θ, we can take the inverse tangent (arctan) of the calculated value:

θ ≈ arctan(1.60638)

Using a calculator or inverse tangent table, we find:

θ ≈ 57.2°

The daily lunch sets cost $6, while the special lunch sets cost $36.

A linear equation with two variables consists of the greatest power of a variable being one.

Now, for the given condition in the question;

Let the price of the daily lunch set is 'x'.

Let the price of the special lunch set is 'y'.

Then, 2 daily lunch sets and 3 special lunch sets costs $120.

2x + 3y = 120     .......(equation 1)

And, 5 daily lunch sets and 2 special lunch sets costs $157.

5x + 2y = 157    ......(equation 2)

Using elimination method to solve equation 1 and 2.

y = 36 (price of each special lunch sets)

x = 6 (price of each daily lunch sets)

Therefore, the price for the daily lunch sets is $6 and price for special lunch sets is $36 in an restaurant.

Answer:

About 2.2 gallons

Step-by-step explanation:

Create the following proportion:

\(\frac{10.5}{4.75}\) = \(\frac{x}{1}\)

Cross multiply.

10.5 x 1 = 10.5

4.75 x X = 4.75x

4.75x = 10.5

Divide both sides by 4.75x.

10.5/4.75 = 2.2

The dark areas and the union symbol on the number line stand for x < 3 or x > 8 respectively.

We must plot the points x = 3 and x = 8 and shade the necessary areas in order to graph the compound inequality x 3 or x > 8 on a number line.

In order to represent all values of x less than 3, we first plot an open circle at 3 and shade the area immediately to its left:

<---|====]--->

  3    8

Finally, to represent all values of x larger than 8, we plot another open circle at 8 and shade the area to its right:

<---|====]---|--->

  3    8   8

Finally, to show that the solution encompasses all values of x greater than or equal to 3, we combine the two coloured zones together with the union symbol "∪":

<---|====]---|--->

  3    8   8

   (x<3)  (x>8)

Solution: The dark areas and the union symbol on the number line denote x 3 or x > 8 respectively.

The correct answer is cycle. A sine or a cosine function represent periodic functions where the value of the function is repeats after a definite interval.

What do you mean by periodic function?

A periodic function can be defined as:

A function returning to the same value at regular intervals. Though periodic motion and oscillatory motion sound the same, not all periodic motions will be oscillatory motion.

Image result for periodic function

If a function has a repeating pattern like sine or cosine, it is called a periodic function. The period is the length of the smallest interval that contains exactly one copy of the repeating pattern.

A motion that repeats itself at regular intervals is termed periodic motion. 1. A motion that does not repeat itself at regular intervals is termed non-periodic motion. 2. After a certain period of time, an object exhibiting periodic motion returns to its original position.

What is area of circle ?

area of circle can be defined as the product of pi and square of radius ,the value of pi is 22/7 or 3.14 .

Given , diameter = 12

We need to convert diameter to r

d =2r

d/2 =r

12/2=r

6 =r

The radius is 6

A= pi *6^2

A = 36 *(3.14)

A = 113.04 cm^2

Now the fraction of the circle that is shaded is 301degrees out of 360

(A circle is 360 degrees)

=310/360 * area of a circle

=310/360 * 113.04

= 97.34
