Answer:

The terms have a common ratio of - 1.5

Step-by-step explanation:

4.8 - ( - 3.2 )

= 4.8 + 3.2

= 8

- 7.2 - 4.8

= - 12

Common difference is not same.

4.8 / - 3.2

= - 4.8 / 3.2

= ( - 4.8 / 16 ) / ( 3.2 / 16 )

= - 3 / 2

= - 1.5

- 7.2 / 4.8

= ( - 7.2 / 24 ) / ( 4.8 / 2.4 )

= - 3 / 2

= - 1.5

Common is ratio is same.

Answer,

The terms have a common ratio of - 1.5

Suggest a fundamentally and conceptually different way that is always under the control of the researcher of making the margin of error smaller.

Answers

Step-by-step explanation:

First, we may wonder, what does the term margin of error mean? Put simply, the margin of error is a measure of the degree to which research results do not reflect the views of the total studied population. In other words, it tells readers how much confidence they should have in the results presented.

It has often been suggested that a fundamentally and conceptually effective way that is always under the control of the researcher of making the margin of error smaller is to increase the sample size of the research. This basically involves collecting more sample data which thus leads to a closer estimate of the view of the entire population.

Segment AB is completely rotated about the y-axis to form a 3-D figure. Find the volume of the figure. The
length of AB is 6.

Answers

Answer:

The volume of the figure is 905 cubic units.

Step-by-step explanation:

Rotation is a method of solid transformation which involve turning a given line, or object about a reference point. In the given question, rotating segment AB completely about the y-axis would form a 3 dimensional figure of a sphere.

volume of a sphere = [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]

where r is the radius of the sphere.

Given that AB = 6, then the radius of the sphere = 6

volume of sphere = [tex]\frac{4}{3}[/tex] x [tex]\frac{22}{7}[/tex] x [tex](6)^{3}[/tex]

                              = [tex]\frac{88}{21}[/tex] x 216

                              = 905.14

volume of sphere = 905 cubic units

The volume of the figure is 905 cubic units.

please someone help me! A farmer builds a fence to enclose a rectangular pasture, he uses 160 feet of fence. Find the total area of the area pasture if it is 50 feet long.

Answers

Answer:

Area= 2000 feet^2

Step-by-step explanation:

Know how to find the perimeter and the area of a rectangle

area=length*width

perimeter= 2*length + 2*width

Draw a rectangle

The question states that the pasture is 50 feet long

So the length of the rectangle pasture should be 50. We can label the 2 lengths of the rectangle to be 50 feet long

Since the farmer only has 160 feet of fence, we can say that because the pasture is a rectangle, we can label the width as 40 because 2*50+2*40=160

Now that we know the length and width, we can find the area by multiplying those 2 values together to get 2000

Step-by-step explanation:

When two parallel lines are cut by a transversal, the corresponding angles are equal.

8x +2 = 7x + 9

Subtract 2 from both sides

8x = 7x + 9 - 2

8x = 7x + 7

Subtract 7x from both sides

8x - 7x = 7

x = 7

Answer:

x=7

Step-by-step explanation:

The 2 given angles are vertical to each other, so that means they are equal to each other.

To solve, set up an equation:

[tex]7x+9=8x+2[/tex]

Solve by isolating the variable. [Subtract and divide]

[tex]7x=8x-7[/tex]

On the first day of travel, a driver was going at a speed of 40 mph. The next day, he increased the speed to 60 mph. If he drove 2 more hours on the first day and traveled 20 more miles, find the total distance traveled in the two days.

Answers

Velocity, distance and time:

This question is solved using the following formula:

[tex]v = \frac{d}{t}[/tex]

In which v is the velocity, d is the distance, and t is the time.

On the first day of travel, a driver was going at a speed of 40 mph.

Time [tex]t_1[/tex], distance of [tex]d_1[/tex], v = 40. So

[tex]v = \frac{d}{t}[/tex]

[tex]40 = \frac{d_1}{t_1}[/tex]

The next day, he increased the speed to 60 mph. If he drove 2 more hours on the first day and traveled 20 more miles

On the second day, the velocity is [tex]v = 60[/tex].

On the first day, he drove 2 more hours, which means that for the second day, the time is: [tex]t_1 - 2[/tex]

On the first day, he traveled 20 more miles, which means that for the second day, the distance is: [tex]d_1 - 20[/tex]

Thus

[tex]v = \frac{d}{t}[/tex]

[tex]60 = \frac{d_1 - 20}{t_1 - 2}[/tex]

System of equations:

Now, from the two equations, a system of equations can be built. So

[tex]40 = \frac{d_1}{t_1}[/tex]

[tex]60 = \frac{d_1 - 20}{t_1 - 2}[/tex]

Find the total distance traveled in the two days:

We solve the system of equation for [tex]d_1[/tex], which gets the distance on the first day. The distance on the second day is [tex]d_2 = d_1 - 20[/tex], and the total distance is:

[tex]T = d_1 + d_2 = d_1 + d_1 - 20 = 2d_1 - 20[/tex]

From the first equation:

[tex]d_1 = 40t_1[/tex]

[tex]t_1 = \frac{d_1}{40}[/tex]

Replacing in the second equation:

[tex]60 = \frac{d_1 - 20}{t_1 - 2}[/tex]

[tex]d_1 - 20 = 60t_1 - 120[/tex]

[tex]d_1 - 20 = 60\frac{d_1}{40} - 120[/tex]

[tex]d_1 = \frac{3d_1}{2} - 100[/tex]

[tex]d_1 - \frac{3d_1}{2} = -100[/tex]

[tex]-\frac{d_1}{2} = -100[/tex]

[tex]\frac{d_1}{2} = 100[/tex]

[tex]d_1 = 200[/tex]

Thus, the total distance is:

[tex]T = 2d_1 - 20 = 2(200) - 20 = 400 - 20 = 380[/tex]

The total distance traveled in two days was of 380 miles.

For the relation between velocity, distance and time, you can take a look here: https://brainly.com/question/14307500

Answer:

Total traveled distance is : 380 miles

Step-by-step explanation:

Let´s call variables of the first day of travel as:

v₁ = 40 mph

Time of travel  unknown but 2 hours more than the second day

Traveled distance ( unknown) but 20 miles more than the second day

And for the second day

v₂ = 60 mph

Time of travel t

Traveled distance s (unknown)

With that information, we can make a model of a two equations system as follows:

We know that s = v*t ( where s is the distance traveled, v the speed, and t the traveled time) then

First day  

Total distance traveled s + 20 is equal to:

s + 20 = 40 * ( t + 2 )

The second day:

s = 60*t

The system is:

s + 20 = 40 * ( t + 2 )

s = 60*t

By substitution

60*t + 20 = 40 * ( t + 2 )

60*t + 20 = 40*t + 80

60*t - 40*t = 80 - 20

20*t = 60

t = 3 hours

Now we can calculate the total distance traveled according to:

First day:  s₁ = 40 (m/h)* (t + 2) (h) = 40*5 miles      s₁ = 200 miles

Second day:

s = 60*t   =  60 (m/h)*3 (h)  =  180 miles

Total distance is : 380 miles

A laboratory tested n= 130 chicken eggs and found that the mean amount of cholesterol was 88 milligrams with -9 milligrams. Find the margin of error E corresponding to a 95% confidence interval for the true mean cholesterol content of all such eggs. Round your answer to the nearest tenth.

Answers

Answer:

The margin of error is of 1.5 milligrams.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Z-table as such z has a p-value of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

Standard deviation of 9

This means that [tex]\sigma = 9[/tex]

Sample of 130

This means that [tex]n = 130[/tex]

Find the margin of error E corresponding to a 95% confidence interval for the true mean cholesterol content of all such eggs.

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]M = 1.96\frac{9}{\sqrt{130}}[/tex]

[tex]M = 1.5[/tex]

The margin of error is of 1.5 milligrams.

Tyrell bought 6 video games this summer. Each game cost 27 dollars. If Tyrell had 379 dollars left after he bought the video games, how much money did he start with?

Answers

Taking into account the total amount of money spent on the games and the money that Tyrell had left after he bought the video games, Tyrell started with $541.

Total amount of money

First you must know the total amount of money spent on the games. For that Tyrell bought 6 video games this summer and each game cost 27 dollars.

So to calculate the amount spent, the number of games purchased must be multiplied by the price of each one:

6 video games* 27 dollars each game= 162 dollars

So Tyrell spends 162 dollars.

Money left over after buying the video games.

On the other hand, you know that Tyrell had 379 dollars left after he bought the video games.

This indicates that after spending $ 162 on video games, there were $ 379 left over.

Money he started with.

To know the amount of money that Tyrell had, you must add the amount spent on games and the money that was left over:

162 dollars + 379 dollars= 541 dollars

So, Tyrell started with $541.

Tyrell started with 541 $

There are two actions in the question.

First Tyrell bought 6 video games, each game cost 27 $.

Spent

According to that Tyrell spent

6 * 27 = 162 $

Keeps

The second fact is that after shopping Tyrell keeps 379 $.

If Tyrell spent 162 $ and still keeps 379 $, that means that the total amount of money Tyrell had is the sum of the money he spent plus the money he has

Now if we call "x" the quantity of money Tyrrel started with: Then

x  =  the money Tyrell spent on video games  plus the remaining 379 $

Then

x  =  162  + 379

x = 541 $

A DEF has vertices D(-5,-1), E (3, 3), and F (1,-5). Find the equation of the altitude through F in
slope-intercept form.

Answers

Answer:

y = -2x -3

Step-by-step explanation:

- the altitude trough F is a perpendicular line to the line DE

- find slope of line DE

D ( x2 = -5, y2 = -1); E (x1 = 3, y1 = 3)

slope m = (y2-y1) / (x2-x1) = (-1-3) / (-5-3) = -4/ -8 = 1/2

-find equation of the altitude trough F

lines that are perpendicular have the slope negative reciprocal (negative reciprocal of 1/2 is -2)

y= -2x +b , for point F(1, -5)

-5 = -2*1 +b, add 2 to both sides

-5 +2 = b, combine like terms

-3 =b

equation of the altitude trough F is y = -2x -3

Answers

Answer:

x = 18

Step-by-step explanation:

Since BD bisects ∠ ABC , then

∠ ABD = ∠ DBC = 79°

∠ ABC = ∠ ABD + ∠ DBC , that is

9x - 4 = 79 + 79 = 158 ( add 4 to both sides )

9x = 162 ( divide both sides by 9 )

x = 18

Since bd bisects the abc is equal to 2 time 79 so solve 2(79)=9x-4 so x is 18
