Does this graph represent a function? Why or why not?

Answer:

Step-by-step explanation:

To make the division easier, we will convert them to improper fraction first.

[tex]12 \frac{3}{8} \div 2 \frac{3}{4} \\ = \frac{99}{8} \div \frac{11}{4} [/tex]

Now we will change the sign to multiply and swap the numerator and denominator of the divisor fraction.

[tex] \frac{99}{8} \div \frac{11}{4} \\ = \frac{99}{8} \times \frac{4}{11} \\ = \frac{396}{88} \\ = \frac{9}{2} = 4 \frac{1}{2} [/tex]

Step-by-step explanation:

If he has $42 in his savings account and he takes $7 a week for 13 weeks, we have to multiply 7x13 to find out how much money he takes out of the account.

7x13=91, 91 is more then how much he has in his account so he will be in debt?
42-91=-49

Jordin after working for 23 hours and 15 minutes would be paid $302. 25

From the information given, we have that;

Let's convert the minutes to hour

60 minutes is equivalent to 1 hour

Then 15 minutes is equivalent = x hour

cross multiply

x = 15/ 60

x= 0. 25 hour

He worked = 23 + 0. 25 = 23.25 hours

Then,

$13. 00 = 1 hour

$x = 23. 25

cross multiply

x = 13 × 23. 25

x = $302. 25

Thus, Jordin after working for 23 hours and 15 minutes would be paid $302. 25

The total number of occasions the dice would land on 1 or 3 is 98.

The probability space associated with a randomly chosen experiment is established by three components: the result space, whose element is an experiment outcome, a collection of events F whose elements represent subsets of, and a probability measure IP assigned towards the elements in F.

As a result, for problems like Cards, Coins, and Dices, it is preferable to record the potential scenarios and determine the individual probabilities of each case before ORing/ANDing them in accordance with the problem demand. If done correctly, this will provide a great solution that will never fail you.

All of the probability will add upto 1.

this give us the equation:

P(1)+0.17 + 0.18 + 0.09 + 0.15 + 0.1 = 1

P(1) + 0.69 = 1

P(1) = 1 - 0.69

   P(1)  = 0.31

We now need to find the probability of 1 or 3

P(1 or 3) = P(1) + P(3)

             = 0.31 + 0.18

             = 0.49

We now use the predicting outcomes formula.

expected = P(1 or 3) x no. of times.

                = 0.49 x 200

                = 98

the total number of times the dice will land on 1 or on 3 = 98.

Answer:

x = -4

Step-by-step explanation:

x - 16 = -20

16 is being subtracted from x. To get x alone, you need to add 16 to x - 16.

We must do the same to both sides of an equation, so we add 16 to both sides of the equation.

x - 16 + 16 = -20 + 16

x = -4

b. 4.5 ÷ 3 = 3 × 1.5 = 4.5 and1.5 × 3 = 4.5

A complete multiplication equation will have the numbers that are being multiplied together on one side of the equal sign, and what they are equal to on the other side of the equal sign.

a. 10 ÷ 5 = ?

First we will solve the given equation

so, 10 ÷ 5 = 2

In simple way we can write the multiplication equation of above equation in two ways :

First we can write it as 2 × 5 = 10

And second is as         5 × 2 = 10

These two don't have different conclusion but they have just different written pattern.

Same as we will do the other equations.

b. 4.5 ÷ 3 = ?

Let's solve the equation first

Answer:

Step-by-step explanation:

For a given atom, net charge can be determined by looking at how many protons the atom has in its nucleus and how many electrons it has surrounding its nucleus.

More specifically, the atom will have

a positive net charge if it has more protons in its nucleus than electrons surrounding its nucleus

a negative net charge if it has more electrons surrounding its nucleus than protons in its nucleus

no net charge if it has equal numbers of protons and electrons

When an atom carries a positive net charge, it forms a cation, or positively charged ion. Likewise, when an atom carries a negative net charge, it forms an anion, or negatively charged ion.

In your case, the atom is said to contain

eight protons

nine neutrons → they do not influence the net charge of the atom

ten electrons

Now, electrons and protons carry opposite charges. A proton is said to carry a 1+ charge, while an electron is said to carry a 1−.

In your case, you have 8 protons and 10 electrons. This means that the atom will carry a total

2×(1−)=2−

net charge.

Therefore, you are dealing with an anion that carries a 2− net charge, i.e. it has two more electrons than it does protons.

A function is a relation that uniquely associates members of one set with members of another set. More formally, a function from A to B is an object f such that every a in A is uniquely associated with an object f(a) in B. A function is therefore a many-to-one (or sometimes one-to-one) relation. The set A of values at which a function is defined is called its domain, while the set f(A) subset B of values that the function can produce is called its range. Here, the set B is called the codomain off.

A function from a set X to a set Y is an assignment of an element of Y to each element of X. The set X is called the domain of the function and the set Y is called the codomain of the function.

A function, its domain, and its co-domain are declared by the notation f: X→Y, and the value of a function f at an element x of X, denoted by f(x), is called the image of x under f, or the value of f applied to the argument x.

Functions are also called maps or mappings, though some authors make some distinction between "maps" and "functions"

The thing that intuition says about the degree measures of these angles is that ABC and DEF are supplementary angles.

It should be noted that the given measures are ABC = 70° and DEF = 110°

it should be noted that supplementary angles are the angles that have the addition as 180°.

The inverse function is given by f⁻¹(x)=∛x+2 and the inverse is a function.

The opposite function is referred to as the inverse of a function. To map the dependent variable y based on the independent variable x, we should ideally utilize a function. The relationship that determines the value of x based on a certain value of y is known as an inverse function.

The domain of a function shifts to the range for an inverse function, and vice versa.

For a function that is mathematically denoted by the formula y=g(x), where g(x) is a polynomial of x. We use y to solve the equation for x.

Given function is in the form  f(x)=(x-2)³

It can be written as

y=(x-2)³

Then we take the cube root on either sides of the equation.

∛y=x-2

or, x=∛y+2

c. iPhone 10 will cost $83 in 2025.

Given sequence is:  

$1000, $700, $490, $343, $240

a. To determine the type of sequence we find the common ratio between terms:

   700/1000 = 7/10

   490/700 = 7/10

All terms differ by a common ratio hence it is a geometric progression.

b. From above,          

 1000 × 7/10 = 700

 700 × 7/10 = 490

 490 × 7/10 = 343

 343 × 7/10 = 240

Hence, the common ratio of G.P is 7/10.

c. The next terms in the given G.P is:

240 × 7/10 = 168

So, iPhone 10 will cost $168 in 2023.

168 × 7/10 = 118

So, iPhone 10 will cost $118 in 2024.
