Answer 1

Answer:

6x^2 -9

Step-by-step explanation:

1. From the table, you know that when x = 0, y = -9, this means that the initial value is -9. This means that the last option is not correct

*** y values -> output

2. Plug in a x - value from the table to figure out the right rule:

x = 2

First option: 6x - 9 -> 6*2 - 9 = 12-9 = 7

in the table, the output for x =2 is 15 so the first option is not correct

Second option: 6x^2 - 9 -> 6*(2^2) - 9 = 6*4 - 9 = 24 - 9 = 15

in the table, the output for x =2 is 15 so the second option is correct

Given:

In figure C,

In triangle AXB and QXR

<BAX = <QRX (given)

<AXB = QXR (Vertical opposite angle)

Jeremy listed five rational numbers. Then he drew a number line to display and compare them.



Plot the numbers on the number line by dragging each one to the correct location.

6/3, -3/4, 1.5, 0.25, -5/4

Answers

Answer:

Step-by-step explanation:

A rational number is a number that can be written in the form [tex]\frac{a}{b}[/tex] where b ≠ 0.

In order to properly arrange the numbers on the number line, we need to arrange it in an ascending order.

6/3 = 2

-3/4 = -0.75

1.5 = 1.5

0.25 = 0.25

-5.4 = -1.25

The numbers written in an ascending order will be,

-1.25 = -5/4

-0.75 = -3/4

0.25

1.5

2 = 6/3

Therefore writing this on the number line, we will have it in this order:

-1.25, -0.75, 0.25, 1.5, 2

Question:Fibonacci

21
Find an expression, in terms of n for the nth term of this quadratic sequence.

Answers

9514 1404 393

Answer:

  n² -n +1

Step-by-step explanation:

First differences of the terms of the sequence are ...

  3-1 = 2

  7-3 = 4

  13-7 = 6

  21-13 = 8

Second differences are ...

  4-2 = 2

  6-4 = 2

  8-6 = 2

In a quadratic sequence the coefficient of the squared term is half of the second difference value. Here, that means the squared term will be (2/2)n² = n².

__

We can find the other terms of the quadratic expression by considering the differences between n² and the actual sequence.

The sequence of n² terms is ...

  1, 4, 9, 16, 25

When we subtract these from the actual sequence, we get ...

  1-1 = 0

  3-4 = -1

  7-9 = -2

  13-16 = -3

  21-25 = -4

That is, the amount subtracted from n² is one less than the term number.

The expression for the n-th term is ...

  an = n² -n +1

It is computed that when a basketball player shoots a free throw the odds in favor of his making our 23 to 3 find the probability that when does basketball player shoot a free throw he misses it out of every 100 free throws he attempts on the average how many should he make

Answers

Answer:

Step-by-step explanation:

So think like a percent 3 percent of 23 of mean multiply so first 23 divided by 100 equals what then to check the answer multiply it by 3

Using the probability concept, it is found that:

There is a 0.115 = 11.5% probability that he misses.Out of 100, on average, he would make 88.5.

A probability is the number of desired outcomes divided by the number of total outcomes.

The odds in favor of his making is 23 to 3, which means that, for each free throw he takes:

The probability of making it is [tex]\frac{23}{23 + 3} = \frac{23}{26} = 0.885[/tex].The probability of missing it is [tex]\frac{3}{26} = 0.115[/tex].

There is a 0.115 = 11.5% probability that he misses.

Out of 100, on average, he would make 0.885(100) = 88.5.
