Answer:192

Step-by-step explanation:

So we got to evaluate:

To calculate this multiplication, we can first consider the numbers without the decimal digits:

Doing this multiplication, we got to:

Now, we count how many decimal places there ir in the initial numbers. We have 3 decimal places in 27.345 and also 3 decimal places in 4.335.

So we have a total of 6 decimal places. To get the result, we put the 6 rightmost digits in decimal places, so we get:

That is the result.

One way of checking it is by firts adding the digits of each number.

So we have 27345, the digits add to:

Since we still have 2 digits, we add them up:

Now, we do the same for 4335:

Now, we multiply this reduced numbers, 3 and 6:

And reduce it:

To check the result, 118540575, we do the same with it and compare:

So we also got to 9. This way, the result is probably right. This is a way of checking the result of a multiplication.

Let p = number of pennies we need to find.

(3/10)/(4/5) = p/440

Solve for p to find your answer.

Answer:

880

Step-by-step explanation:

Multiply the numerator and the denominator of 4/5 by 2 so it can be added. Rachel's bank would now be 8/10 full. If 440 pennies made it half full (8/10-3/10= 5/10, which equals 1/2) then 880 pennies (440 times 2) would fill it up completely. Hope this helps!

When a child is confronted in front of his parents about stealing cookies from Jar, the function used is substituting function.

The substituting function replaces verbal communication. The primary role of bodily structure in substituting function is Nonverbal communication includes substituting.

Thus, the above statement is a example of nonverbal communication's replacing function, as the child is confronted by his body language in front of a parent when he steals the cookies.

Communication is a continual process that consists primarily of three components: sender, message, and recipient.

verbal communication:

Oral communication is communication that occurs by verbal, verbal, or written communication that delivers or conveys a message to others. The use of language to convey information vocally or in sign language is known as verbal communication.

non- verbal communication:

It can happen with signs, symbols, colors, touches, body parts, or face features. Insignificant communication is the use of body language, facial expressions, and body language to send information to another. It can be used both purposefully and unintentionally. For example, when you hear an idea or a piece of new or exciting information, you may smile.

The probability of both rice and carrots being served with dinner is 23.4%.

The probability of Alvin's mother serving rice with dinner can be expressed using the formula P(Rice) = 0.78. This means that the probability of Alvin's mother serving rice with dinner is 78%. The probability of Alvin's mother serving carrots with dinner can be expressed using the formula P(Carrots) = 0.30. This means that the probability of Alvin's mother serving carrots with dinner is 30%. To calculate the combined probability of both rice and carrots being served with dinner, we can use the formula P(Rice and Carrots) = P(Rice) * P(Carrots) = 0.78 * 0.30 = 0.2340. This means that the probability of both rice and carrots being served with dinner is 23.4%.

The greatest common factor (GCF) of the terms in the polynomial \(8x^4 - 4x^3 -18x^2\) is \(2x^2.\)

To find the greatest common factor (GCF) of the terms in the polynomial \(8x^4 - 4x^3 - 18x^2\), we need to identify the largest expression that divides evenly into each term.

Let's break down each term individually:

\(8x^4\) can be factored as 2 × 2 × 2 × x × x × x × x

\(-4x^3\) can be factored as -1 × 2 × 2 × x × x × x

\(-18x^2\) can be factored as -1 × 2 × 3 × 3 × x × x

Now, let's look for the common factors among these terms:

The common factors for all the terms are 2 and \(x^2\).

The turtle and snail are apprοaching each οther at a rate οf 6 feet per minute.

Let's use the cοncept οf relative speed tο sοlve this prοblem. The relative speed οf twο οbjects mοving tοwards each οther is the sum οf their individual speeds.

Relative speed is the speed οf an οbject οr persοn in relatiοn tο anοther οbject οr persοn. It is the difference between the velοcities οf twο οbjects mοving relative tο each οther. The relative speed can be calculated by subtracting the velοcity οf οne οbject frοm the velοcity οf the οther οbject.

Let's call the rate at which the turtle and snail are apprοaching each οther "r".

Relative speed = turtle's speed + snail's speed

The answer of the given question based on graph is, we add a self-loop to each vertex that does not already have one.

The reflexive closure of a relation on a finite set can be constructed from the directed graph representing the relation by adding a self-loop to each vertex that does not already have one.

Let R be a relation on a finite set A.

The directed graph representing R has an arrow from a vertex a to a vertex b if and only if (a, b) ∈ R.

The reflexive closure of R is the relation R ∪ {(a, a) | a ∈ A},

which can be represented by the directed graph that is the same as the graph representing R,

except that each vertex a that does not have a self-loop in the graph representing R is given a self-loop in the graph representing the reflexive closure of R.

In other words, we add a self-loop to each vertex that does not already have one.

It is important to note that the reflexive closure graph may have additional edges compared to the original graph due to the added self-loops.

To construct the directed graph representing the reflexive closure of a relation on a finite set from the directed graph of the original relation, you can follow these steps:

1. Start with the directed graph of the original relation.

2. For each vertex (node) in the graph, add a self-loop (a directed edge that starts and ends at the same vertex). This ensures that each element in the set is related to itself, fulfilling the reflexive property.

3. If there were any existing edges in the original graph that connected two vertices, leave them as they are.

4. The resulting graph represents the reflexive closure of the original relation.

By adding the self-loops, you ensure that every element in the set is related to itself, which is a requirement for reflexivity. The other edges in the original graph, if any, are left unchanged as they represent the existing relations between elements.

It is important to note that the reflexive closure graph may have additional edges compared to the original graph due to the added self-loops.

where,

Z- score, μ is the mean, and σ is the standard deviation

It is given that,

μ = $30.44

σ = $14.99

To find the probability that Bo, Colleen, Jeff, and Rohini win the first, second, third, and fourth prizes, respectively, in a drawing with 50 people, follow these steps:

1. Since winning more than one prize is allowed, the probability of Bo winning the first prize is 1/50.

2. Likewise, the probability of Colleen winning the second prize is also 1/50.

3. Similarly, the probability of Jeff winning the third prize is 1/50.

4. Finally, the probability of Rohini winning the fourth prize is 1/50.

5. Since these events are independent, we can multiply the probabilities together to find the overall probability of this specific  :

The value of "a" if the area (in square units) of the region under the curve of the function f(x)=5 , on the interval from x=a to x=8 is 20 square units is 4

The given horizontal line is y = f(x) = 5 while the interval x=a and x= 8 represent vertical lines that intersect x = a and x = 8.

The area above the x-axis that is bound by f(x) on the top and x=a and x=8 on the sides is a rectangle with width of 5units and length (8 - a)units.

The area pf the rectangle is expressed as:

Area = length * width

Substitute

20 = 5(8-a)

(8-a) = 20/5

8-a = 4

-a = 4 - 8

-a = -4

a = 4
