Answer:

The answer is the second option

Step-by-step explanation:

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:

1,120 yd²

Step-by-step explanation:

Surface area of the triangular prism = (bh) + (s1 + s2 + s3)*L

Where,

b = 15 yd

h = 8 yd

s1 = 17 yd

s2 = 15 yd

s3 = 8 yd

L = 25 yd

Substitute

Surface area = (15*8) + (17 + 15 + 8)*25 = 120 + 40*25 = 120 + 1,000

Surface area = 1,120 yd²

Answer:

3

Step-by-step explanation:

by looking at the table, see when f(x)=0.

you can see that when f(x)=0 x=3

the assumption here is that both triangles are similar, if that's so, then we can use proportions to get the sides.

\(\stackrel{\textit{assuming both triangles are similar}}{\cfrac{x}{10}=\cfrac{15}{6x}\implies \cfrac{x}{10}=\cfrac{5}{2x}}\implies 2x^2=50 \\\\\\ x^2=\cfrac{50}{2}\implies x^2=25\implies x=\sqrt{25}\implies \boxed{x=5}\)

The relationship "P varies with D and U and inversely with V" can be written mathematically as:

P = K * (D * U) / V

where K is the constant of proportionality.

This equation shows that P is directly proportional to the product of D and U, and inversely proportional to V. As V increases, P decreases, while as D or U increase, P also increases, assuming all other variables remain constant. The constant of proportionality K is determined by the specific situation and the units used for each variable.

Angie decorates 8 cupcakes after putting 4 sugar flowers on each cupcake.

To find the number of cupcakes c Angie decorates, we can use the equation:4c = 32where 'c' is the number of cupcakes Angie decorates.

4 represents the number of sugar flowers Angie puts on each cupcake, and 32 is the total number of sugar flowers Angie puts on the cupcakes.

To solve this equation for c, we need to isolate c on one side of the equation. We can do this by dividing both sides of the equation by 4. This gives us:c = 8

Therefore, Angie decorates 8 cupcakes.Here's how we get to this answer:4c = 32Divide both sides by 4 to isolate c:c/4 = 32/4c = 8

Answer:

11

Step-by-step explanation:

Let a= times he hit 4 par

Let b = times he hit 5 par

a+b=18 => 4a+4b = 72

4a+5b=79

b=79-72=7

So a = 11

answer:

18 = 4a + 5b = 79, b = 79 - 72 = 7 → 11 holes

i hope this helps ♡♡♡

Answer:

The removed number is 11.

Step-by-step explanation:

Given that the average of 5 numbers is 7. So you have to find the total values of 5 numbers :

\(let \: x = total \: values\)

\( \frac{x}{5} = 7\)

\(x = 7 \times 5\)

\(x = 35\)

Assuming that the total values of 5 numbers is 35. Next, we have to find the removed number :

\(let \: y = removed \: number\)

\( \frac{35 - y}{4} = 6\)

\(35 - y = 6 \times 4\)

\(35 - y = 24\)

\(35 - 24 = y\)

\(y = 11\)

Okay, let's slightly generalize this

Average of \(n\) numbers is \(a\)

and then \(r\) numbers are removed, and you're asked to find the sum of these \(r\) numbers.

Solution:

If average of \(n\) numbers is \(a\) then the sum of all these numbers is \(n\cdot a\)

Now we remove \(r\) numbers, so we're left with \((n-r)\) numbers. and their. average will be \({\text{sum of these } (n-r) \text{ numbers} \over (n-r)}\) let's call this new average \( a^{\prime}\)

For simplicity, say, sum of these \(r\) numbers, which are removed is denoted by \(x\) .

so the new average is \(\frac{\text{Sum of } n \text{ numbers} - x}{n-r}=a^{\prime}\)

or, \( \frac{n\cdot a -x}{n-r}=a^{\prime}\)

Simplify the equation, and solve for \(x\) to get,

\( x= n\cdot a -a^{\prime}(n-r)=n(a-a^{\prime})+ra^{\prime}\)

Hope you understand it :)

Por métodos de resolución de sistemas de ecuaciones no lineales, el valor de a · b tal que a y b son números reales positivos es igual a 3 / 4.

En esta pregunta encontramos un sistema de dos ecuaciones no lineales con dos variables y se nos solicita determinar el producto de dos números reales positivos. Por la ley de signos conocemos que el producto de dos números de igual signo es igual a un número positivo. El sistema es el siguiente:

1 / a + 1 / b = 8 / 3         (1)

a² + b² = 5 / 2               (2)

De (1):

(b + a) / (a · b) = 8 / 3

(a + b)² / (a · b)² = 64 / 9

(a² + 2 · a · b + b²) / (a · b)² = 64 / 9

a² + 2 · a · b + b² = (64 / 9) · (a · b)²

(a² + b²) + 2 · a · b = (64 / 9) · (a · b)²

(2) en (1):

5 / 2 + 2 · a · b = (64 / 9) · (a · b)²

(64 / 9) · (a · b)² - 2 · a · b - 5 / 2 = 0

128 · (a · b)² - 36 · a · b - 45 = 0

Por la fórmula cuadrática encontramos las siguientes raíces:

(a · b)₁ = 3 / 4, (a · b)₂ = - 15 / 32

Solamente la primera raíz satisface las condiciones del problema.

Answer:

2x ( -3x + 14)

Step-by-step explanation:

Distribution property is used in a format like a ( b + c ). To simplify these kinds of expressions, we multiply the outside term by each of the inside terms. So in this instance, a ( b + c ) is equal to ab + ac.

3x ( 2x - 8 ) + 4x

Let's use what we learned above, and multiply the outside term (-3x) by each of the inside terms.

-3x · 2x + (-3x) · (-8) +4x

Simplify by multiplication:

-6x² + 24x +4x

Finally, we add:

-6x² +28x

Now, to simplify further, we can look for terms that show up in numbers.

We can see that the variable x is present in each of the terms, so we can factor that out, removing it from the term as follows:

x ( -6x + 28)

We can look and see that 2 is also a common factor between the two terms, so we can take that out too.

2x ( -3x + 14)

This is the most simplified it can get.
