What is the absolute value of 3 by 5?; What's the absolute value of 3?; What is the negative absolute value of 3?; What is the absolute value of 5 on the number line?

Answer:

slope is undefined

Step-by-step explanation:

calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (16, - 9 ) and (x₂, y₂ ) = (16, 13 )

m = [tex]\frac{13-(-9)}{16-16}[/tex] = [tex]\frac{13+9}{0}[/tex] = [tex]\frac{22}{0}[/tex]

since division by zero is undefined then slope of line is undefined.

The probability of the following event. The first die is 3 or the sum is 6 would be 1/4.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events.

All events must have a probability of occuring at least once, or 1.

The proportion of positive outcomes to all outcomes is referred to as the probability formula.

Let's assume that the blue die came up first among the two.

A = the amount of times we roll a first-die and get a 3.

B is the quantity of times a total of six occurs.

Now Locate 3 on the blue die and notice there are 6 occurrences when this happens which corresponds to the 6 other possibilities for the red die. So we have A = 5.

Also,there are 5 occurrences of the sum "6" in the table. So B = 5.

We have A+B = 5+5 = 10 occurrences of either the first die is 3 or the sum is 6.

However, we have to subtract off 1 because we double counted "6" when adding A and B.

So in reality we have 10-1 = 9 times this happens.

This is out of 36 total ways to roll two dice.

Therefore, the probability of the following event.

The first die is 3 or the sum is 6 would be 9/36 = 1/4

A reflexive, symmetric, transitive binary connection is an equivalence relation. One such illustration of an equivalence relation is the relation of equipollence between line segments in geometry.

demonstrate the equivalence of R. We must demonstrate

1). reflexive

R is reflexive

2). symmetric

let (x,y )  ∈ R

x + 2y = 3a for some a ∈ R

consider y +2x = y + 2(3a - 2y)

6a - 3y = 3(2a - y) = 3k

R is symmetric

3). transitive

(x,y) and (y,x) ∈ R

In coin changing problem,  the greedy strategy fails for the denominations 25, 20, 10, 5, and 1 cents.

The greedy algorithm for the coin change problem (pay a certain amount with the fewest number of coins feasible) is effective. It always chooses the coin with the largest denomination that does not exceed the remaining sum, and it consistently determines the right answer for certain coin sets.

But for certain set of denominations, it fails. For example take a sum of 44 cents then by greedy algorithm, first taking the highest denominations one 25 cent is taken and now 19 is remaining. So now one 10 cent is taken, and 9 is remaining. Now, one 5 cent is taken and four 1 cent is taken. So total we get 7 coins.

Now let us deviate from greedy algorithm and take two 20 cents, now 4 is remaining. So now four 1 cent is taken, this sums up only 6 coins. So this is a much optimal solution than the one obtained by greedy algorithm.

To calculate for the unknown number represented by the question mark (?), we first expand the left hand side of the equation and then compare with the expression at the right hand side of the equation.

From the left hand side;

12(−1.4m+0.4) = -16m + 4.8 {by expansion}

12(−1.4m+0.4) = 0.2 × -84m + 0.2 × 0.2 {factor out 0.2 from both terms}

Are x = 3 and x = -3

Here we have the following equation:

(6x - 12)/3 + 4 = 18/x

Notice that in the right side we have x on a denominator, then x can not be zero, so x ≠ 0.

Now, let's start by simplifying the left side:

(6x - 12)/3+  4 = 18/x

2x - 4 + 4 = 18/x

2x = 18/x

Now we can multiply both sides by x so we get:

Answer:

$292.36

Step-by-step explanation:

To calculate the total amount Nadia will have to pay the bakery to deliver the éclairs, you need to determine how many boxes of éclairs she will need to order and then add the delivery charge.

First, you need to determine how many éclairs Nadia will need to order to feed all of her guests. Since there are 8 éclairs per box and Nadia has 76 guests in addition to herself and Elizabeth, a total of 78 people, she will need to order 78 / 8 = <<78/8=9.75>>9.75 boxes of éclairs.

To calculate the total cost of the éclairs, you can multiply the number of boxes needed by the cost per box: 9.75 boxes * $24 per box = $<<9.75*24=234>>234.

To calculate the total delivery charge, you can multiply the number of boxes needed by the delivery charge per box: 9.75 boxes * $5.95 per box = $<<9.75*5.95=58.36>>58.36.

To find the total amount Nadia will have to pay the bakery, you can add the cost of the éclairs to the delivery charge: $234 + $58.36 = $<<234+58.36=292.36>>292.36.

Therefore, Nadia will have to pay the bakery a total of $292.36 to deliver the éclairs.

Answer:

[tex]\boxed{292.4625}.[/tex]

Step-by-step explanation:

To determine the total amount Nadia will have to pay the bakery to deliver the eclairs, you will need to first calculate the total number of eclairs that are needed. Since Nadia and Elizabeth will both be attending the party, and there will be a total of 76 friends attending, the total number of people at the party will be 76 + 2 = 78.

Next, you will need to determine how many boxes of eclairs Nadia will need to order. Since each box contains 8 eclairs, and there are 78 people at the party, Nadia will need to order 78 / 8 = <<78/8=9.75>>9.75 boxes of eclairs.

Since the bakery charges $24 per box of eclairs and Nadia needs to order 9.75 boxes, the cost for the eclairs will be 24 * 9.75 = $<<24*9.75=234>>234.

In addition to the cost of the eclairs, Nadia will also need to pay a delivery charge of $5.95 per box. Since Nadia needs to order 9.75 boxes, the delivery charge will be 5.95 * 9.75 = $<<5.95*9.75=58.4625>>58.4625.

To find the total amount Nadia will have to pay the bakery, you will need to add the cost of the eclairs and the delivery charge. The total amount Nadia will have to pay the bakery will be: $234 + $58.4625 = $<<234+58.4625=292.4625>>292.4625. Answer: \boxed{292.4625}.
