Which of these functions had a greater rate of change than the function graphed below, and why?

Answers

Answer:

Step-by-step explanation:

When we talk of rate of change, we talk of the slope of the line

If we had a line;

y = mx + b

m is the slope ( which is the rate of change)

To get the slope of the line, we select any two points on the line and apply the slope formula

m = y2-y1/x2-x1

let us take points (0,0) and (3,9)

m = 9-0/3-0 = 9/3 = 3

The slope here is 3

so from the option, we can see that the third option is the correct answer

The next three terms are 3, 12 and 21.

What is Arithmetic Sequence?

An arithmetic progression (AP) can be defined in one of two ways:

A series in which the differences between each pair of following terms are the same is known as an arithmetic progression.An arithmetic progression is a sequence in which every phrase—aside from the initial term—is created by multiplying the previous term by a predetermined amount.

Given:

-33, -24, -15, -6, ...

first term,

a=-33

d= -24 + 33 = 9

so, [tex]a_5[/tex] = a+ 4d

= -33 +4(9)

= 3

[tex]a_6[/tex] = a+ 5d

= -33 +5(9)

= 12

[tex]a_7[/tex] = a+ 6d

= -33 +4(9)

= 21

Hence, the next three terms are 3, 12 and 21.

After a tropical storm in a certain state, news reports indicated that 19 percent of households in the state lost power during the storm. A state engineer believes that estimate is too low. The engineer will collect data to perform a hypothesis test on the proportion of all households without power. Which of the following are the appropriate hypotheses for such a test?

Answers

Answer:

Step-by-step explanation:

The null hypothesis is that p=0.19. The engineer says that this estimate is too low, meaning he believes the true proportion is greater than 0.19 - p>0.19. Because this is a proportion of ALL houses in the state, we use p rather than phat, leaving D as the correct answer.

(HELP PLEASE I BEG)The amount of money that Maria had in a savings account at the beginning of 2018 was $2,750. At the beginning of 2019, the same savings account now had $3,201 in it.
By what percent did Maria’s savings increase from 2018 to 2019? Show the work that leads to your answer and do not round.

Answers

Step-by-step explanation:

First, you need to find the difference 3201-2750=451, it has increased by 451, then divide the difference by the original number, which is 2750 because thats what she started off with (3201 would be the new number)

Increase% = Increase ÷ Original Number ×100

451÷2750×100=16.4%

The percent of Maria’s savings increase from 2018 to 2019 will be 16.4%.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

The amount of money that Maria had in a savings account at the beginning of 2018 was $2,750.

And, At the beginning of 2019, the same savings account now had $3,201 in it.

Now,

The increased amount = $3,201 - $2,750

= $451

So, The percent of Maria’s savings increase from 2018 to 2019 is,

⇒ Increased percent = 451/2750 × 100

= 16.4%

Thus, The percent of Maria’s savings increase from 2018 to 2019 = 16.4%.

Substitute each variable to determine whether the inequality statement is true or false.

1.) 9 > d , d = 3

2.) -16 > -f , f = 15

Answers

Part 1)

Given the inequality

9 > d

and

d = 3

substituting d = 3 in the inequality

9 > d

9 > 3

TRUE!

Reason: 9 is indeed greater than 3.

Thus,

9 > d , d = 3 is a TRUE statement.

Part 2)

Given the inequality

-16 > -f

and

f = 15

substituting f = 15 in the inequality

-16 > -f

-16 > -15

FALSE!

Reason: -16 is NOT greater than -15.

Thus,

-16 > -f , f = 15 is a FALSE statement.
