What is the 12th term of the geometric sequence where *

A7 = 7 and 10 = -56
O-448
0-224
O -112
0 -96

Answers

Answer 1

Answer:

-224

Step-by-step explanation:

Geometric sequence is given by An = A*R^(n-1)

Given A7 = 7 and A10 = -56

A10/A7 = -8 = R^(10-7)

R^3 = -8

R = -2

A12 = A10*R^2

= -56*-2^2

= -224

Answer 2

Answer:

Step-by-step explanation:

A7 = 7

A10 = -56

7xRxRxR = -56

R = -2

A12 = A10xRxR

= -56 x -2 x -2

= 224

please help me with this equation

Answers

Ok
First we need to find x

9 < 4x - 7

Since the equation is not set up properly we need to switch it from right to left.

7 - 4x > 9

Now we solve

7 - 4x > 9

First we add 7 on both sides

7- will be 7+

-7+7 =0

9 + 7 = 16

Next we divided 4 on both sides

4/4=0 ( I know it should be 1 but that’s how it goes)

16/4= 4

So x=4

Equation

X > 4

this symbol > on a time line always must be open.

Since the symbol is facing left on the time line it must face the opposite side which is right.

So the answer is D

Step 1: Subtract 5x from both sides.
3x + 8 − 5x = 5x − 40 − 5x
−2x +8 = −40

Step 2: Subtract 8 from both sides.
−2x + 8 − 8 = −40 − 8
−2x = −48

Step 3: Divide both sides by -2.
−2x − 2 = −48 −2
x = 24

Eighteen students decide they don't want to be
rescued and want to continue to live in the
jungle. If this represents 40% of the students,
how many students want to be rescued?

Answers

Answer:

27

Step-by-step explanation:

There are 45 students in total and 18 want to continue living in the jungle

45-18=27

*Answer is 27*

x= total number of students in the jungle

18 40
— = ——
X 100

Cross multiply to get 1800/40 so x=45

45 is the total number, if 18 don’t want to be rescued that means the rest (45-18= 27) want to be rescued.

Why should you write everything down instead of doing the math in your head?

Answers

Answer and Step-by-step explanation:

It ensures that you don't accidently skip a step or get confused by which numbers are being used. By writing it down, it allows you to look back and see if you answer was correct or incorrect.

For example:

On a test, you need to do a complicated math problem that you know you can do in your head. It would still be a good idea to write down the process, so that you can see in front of you the numbers you get and results. If it is incorrect when checking over you answers, then you can go through the steps you made to see where you made a mistake.

Yes, the null hypothesis can be rejected at the significance level a = 0.05, because 100 is not contained in the and

Answers

Answer:

Variance of this population = 9,409

Step-by-step explanation:

Given:

Standard deviation of population = 97

Random sample size = 26

Find:

Variance of this population

Computation:

Standard deviation (σ) = 97

Variance = Standard deviation²

Variance = (σ)²

Variance of this population = Standard deviation of population²

Variance of this population = 97²

Variance of this population = 9,409

write the slope-intercept form of the equation of each line.

Answers

Answer:

[tex]y=2x+3[/tex]

Step-by-step explanation:

1. Approach

Slope intercept form is a way of expressing an equation of a line using the slope of a line, and its y-intercept. The general format for the equation of a line in slope-intercept form is the following,

[tex]y=mx+b[/tex]

Find each of the missing pieces of information and substitute it into the equation to find the equation of the line.

2. Find the slope

The slope of a line is the change in the line is can be found using the following formula,

[tex]\frac{y_2-y_2}{x_2-x_1}[/tex]

As one can see on the given graph, two points on the line are the following,

[tex](-2, -1), (-1, 1)[/tex]

Substitute the points into the formula and solve for the slope,

[tex]\frac{(1)-(-1)}{(-1)-(-2)}[/tex]

[tex]=\frac{2}{1}\\\\=2[/tex]

3. Find the y-intercept

The y-intercept of a line is where the line intersects the y-axis. As one can see this point is the following,

[tex](0,3)[/tex]

Thus the y-intercept is (3).

4. Put the information together

Putting all of this information together, substitute the found information into the general equation for slope-intercept form. One can see that the equation of a line is the following,

[tex]y=2x+3[/tex]

Answers

Answer: x-4>-9 or x-4<9

Step-by-step explanation:

The correct option for the given inequality is x-4>-9 or x-4<9

What is an inequality?

A relationship between two expressions or values that are not equal to each other is called inequality.

Given an inequality, |x-4| < 9

Using the rule, if |x| < a then, -a < x < a.

Therefore,

|x-4| < 9

-9 < x-4 < 9

x-4 > -9 or x-4 < 9

Hence, The correct option for the given inequality is x-4>-9 or x-4<9

Answer:

68% of the population will have a height between 64 and 72 inches

Step-by-step explanation:

According to the Empirical Rule, 68% of the population will have a height within the range of 1 standard deviation of the mean. This means that the range of possible heights for 68% of the population is between 68-4(1)=64 inches and 68+4(1)=72 inches

It will output a representation of how the jobs are executed.DesignYou may design your own implementation approach, but here are a few constraints.Your program should read in a list of jobs from a tab-delimited text file named jobs.txt. The format of the text file should have one line for each job, where each line has a job name, a start time and a duration. The job name must be a letter from A-Z. The first job should be named A, and the remaining jobs should be named sequentially following the alphabet, so if there are five jobs, they are named A-E. The arrival times of these jobs should be in order.The scheduler choice should be a command-line parameter that is one of the following: FCFS, RR, SPN, SRT, HRRN, FB, ALL. If ALL is input, the program should produce output for all six scheduling algorithms. RR and FB should use a quantum of one. FB should use three queues.Your output should be a graph as shown in the slides. The graph can be text or you can use a graphics package such as JavaFX to draw the graph.
