<h2>Answer:</h2>

Hence, the probability that the two coins are of different denomination is:

                            2/3

<h2>Step-by-step explanation:</h2>

Let N denote nickel, D denotes dime and Q denotes Quarter.

Now when two coins are drawn one after the other with replacement then the outcomes is given by:

         (N,N)     (N,D)      (N,Q)

         (D,N)     (D,D)      (D,Q)

         (Q,N)     (Q,D)      (Q,Q)  

This means that there are a total of  9 outcomes.

The outcomes such that both the denominations are different i.e. the number of favorable outcomes are:  6

{ (N,D) (N,Q) (D,N) (D,Q) (Q,N) (Q,D) }

The probability that the two coins are of different denomination is:

                             6/9=2/3

Suppose a river flows south to north at a velocity of 1 m/s, and a motorboat traverses the river from east to west at a speed of
irina1246 [14]

Answer: 24^{\circ}

Step-by-step explanation:

Given

River is flowing from south to North with a velocity of u=1\ m/s

Motor boat traverses the river from east to west at a speed of v=2.5\ m/s

South component of boat velocity must compensate the river velocity in order to travel in west direction.

\therefore v\sin \theta=u\\\\\Rightarrow 2.5\sin \theta=1\\\\\Rightarrow \sin \theta=\dfrac{2}{5}\\\\\Rightarrow \theta=23.57^{\circ}\approx 24^{\circ} \text{south of west}

The greatest integer function, shown below, is defined to be the greatest___ less than or equal to x.
Nataly_w [17]

Answer:

Integer

Step-by-step explanation:

The greatest integer function, F(x)=[[x]], is defined to be the greatest <u>integer that is </u>less than or equal to x.

The Greatest Integer Function is also referred to as the Floor Function.

It is written as  F(x)=[[x]]

The value of ⌊x⌋ is the largest or the greatest integer that is less than or equal to x

How to solve -2(-4f+5)=-7+2f-9
Damm [24]

Answer:

f=\frac{3}{5}

Step-by-step explanation:

-2(4f+5)=-7+2f-9

First, use PEMDAS to distribute the -2 to the parenthesis.

-8f -10 = -7+2f -9

Combine like terms on the right side.

-8f - 10 = -16+2f

Now, you may either subtract the f's or the constants. I'll subtract the constants first, meaning I will add 10 to both sides.

-8f = -6 + 2f

Now subtract the 2f from both sides.

-10f = -6

Divide both sides by 10.

f = \frac{-6}{-10}

Simplify.

f = \frac{3}{5}

The group of points {(0, 1), (0, 5), (2, 6), (3, 3)} is not a function, but the group of points {(1, 4), (2, 7), (3, 1), (5, 7)}
notka56 [123]

You can use the definition of a function to classify which mapping is a function and which mapping is not a function.

The first group is not a function as there are two outputs for 0

The second group is a function as there are single output to each input.

<h3>What is a function?</h3>

There are two sets of values. When we connect first set's values with other set, it is called mapping one set's value to other set. All type of mappings are called relations.

Such relations which are such that each element of the first set(also called input set or domain) is mapped to only one value of the other set(called codomain, and if all values are occupied, then called range or output set), then such relation is called function.

So, for a mapping to be function, we need each input to be mapped to only one output.

<h3>Using above definition</h3>

For group 1, we see that 0 has output 1 and output 5 both. Since for a mapping to be a function, we need each input to have single output, thus, this group doesn't represent a function.

For group 2, we see that each input has only one output, thus,this group represents a function.

Remember that we assumed that the pair of points were written as

(input, output)

Thus.

The first group is not a function as there are two outputs for 0

The second group is a function as there are single output to each input.
