Edward solved the equation 4X + 1 = 5x +(-5)
Add 4 negative both sides
Add 5 negative to both side
=4
What’s was mistake

Answers

Answer 1

Answer:

He should have added 5 to each side instead of -5

Step-by-step explanation:

4X + 1 = 5x +(-5)

Subtract 4x from each side

4X-4x + 1 = 5x-4x +(-5)

Combine like terms

1 = x-5

Add 5 to each side  

He should add 5 to each side ( we need to add the opposite of (-5)) to undo the adding  of (-5)

1+5 = x-5+5

6 =x

A satellite 200 miles above the earth is orbiting the earth once every 6 hours. How far does the satellite travel in 1 hour?
(Assume the radius of the earth is 4,000 miles.) Give your answer as both an exact value and an approximation to three significant digits

Answers

Answer:

The answer is below

Step-by-step explanation:

Speed is the ratio of total distance travelled to total time taken to cover distance.

The radius of the orbit = radius of earth + height of satellite from earth = 4000 miles + 200 miles = 4200 miles

The total distance around the orbit = perimeter of orbit = 2π(radius of orbit) = 2π(4200) = 8400π miles

[tex]Speed=\frac{distance \ traveled}{time\ taken} =\frac{8400\pi\ miles}{6\ hours} =1400\pi\ miles/hour\\\\Distance \ traveled\ in \ 1\ hour=1400\pi\ miles/hour*1\ hour=1400\pi\ miles=4398.23\ miles\\\\Distance=4398\ miles[/tex]

Solving the for angle NMP. *

Answers

Answer:

50°

Step-by-step explanation:

Angle NMP is an angle that has its vertex on a point along the circumference of the circle, thus, angle NMP is referred to as an inscribed angle of the circle.

The measure of an inscribed angle is equal to half of the measure of the arc it intercepts.

Therefore, the following equation shows the relationship between inscribed angle NMP and arc NP:

m<NMP = ½ × measure of arc NP

m<NMP = ½*100

m<NMP = 50°

a. The response variable is__________ and the explanatory variable is_________

i. 0.846.
ii. -4.681
ii. -0.858.
iv. 45.459
v. -8.999.

Answers

Answer:

A. Response Variable is POUND SOLD Explanatory variable is PRICE PER POUND

B. ii. -4.681

Step-by-step explanation:

A. Based on the statistics that was shown in the given information above the:

Response Variable is POUND SOLD Explanatory variable is PRICE PER POUND

B. Calculation to determine slope of the estimated regression line that relates the response variable to the predictor variable

Using this formula

Slope =r*Sy/Sx

Let plug in the formula

Slope=-0.927*18.33/3.63

Slope=-16.99191/3.63

Slope=-4.681

Therefore , the slope of the estimated regression line that relates the response variable to the predictor variable is: -4.681

Suppose that a sample of n students at the same university​ (instead of n​) determines that ​% of the sample use the web browser. At the level of​ significance, is there evidence that the market share for the web browser at the university is greater than the worldwide market share of ​%?

Answers

Complete Question

The worldwide market share for a web browser was 20.5​% in a recent month. Suppose that a sample of 200 random students at a certain university finds that 50 use the browser.

At the 0.05 level of​ significance, is there evidence that the market share for the web browser at the university is greater than the worldwide market share of 20.5​%?

Answer:

The decision rule is

Fail to reject the null hypothesis

The conclusion is

There is no sufficient evidence to show that the market share for the web browser at the university is greater than the worldwide market share of  20.5 ​%?

Step-by-step explanation:

From the question we are told that

          The population proportion is  [tex]p = 0.205[/tex]

          The sample size is  n  =  200

          The number that uses the browser is  k =  50

          The level of significance is  [tex]\alpha = 0.05[/tex]

         

Generally the sample proportion is mathematically represented as

       [tex]\^ p = \frac{50}{200}[/tex]

=>    [tex]\^ p = 0.250[/tex]

The null hypothesis is  [tex]H_o : p = 0.205[/tex]

The  alternative hypothesis  is  [tex]H_a : p > 0.205[/tex]

Generally the test statistics is mathematically represented as

          [tex]z = \frac{ \^ p - p }{ \sqrt{ \frac{ p (1 - p )}{ n} } }[/tex]

=>       [tex]z = \frac{ 0.250 - 0.205 }{ \sqrt{ \frac{ 0.205 (1 - 0.205 )}{ 200} } }[/tex]

=>       [tex]z = 1.5764[/tex]

Generally the area under  [tex]z = 1.5764[/tex]  to the right is  

     [tex]p-value = P( Z > 1.5764 ) = 0.057467[/tex]

From the value we obtained we can see that the [tex]p-value > \alpha[/tex] hence

 The decision rule is

Fail to reject the null hypothesis

   The conclusion is

There is no sufficient evidence to show that the market share for the web browser at the university is greater than the worldwide market share of 20.5 ​%?

how do I solve for 3(2x-1)+2x=4x-11

Answers

Answer:

x=-2

Step-by-step explanation:

3(2x-1)+2x=4x-11

6x-3+2x=4x-11

8x-3=4x-11

8x=4x-8

4x=-8

x=-2

The answer to the equation is [tex]x=-2[/tex]

First, you must use distributive property to simplify the equation.

[tex]6x-3+2x=4x-11[/tex]

Then, you must combine like terms.

[tex](6x+2x)-3=4x-11[/tex]

[tex]8x-3=4x=11[/tex]

Next, you must subtract 4x on each side

[tex]4x-3=-11[/tex]

Then, add 3 on both sides

[tex]4x=-8[/tex]

Finally, divide both sides by 4

[tex]\frac{4x}{4} =\frac{-8}{4}[/tex]

[tex]x=-2[/tex]

so for 1 hour, he gets = 175÷20 => $8.75 per hour
