how to find coefficient of x²in 2+x²+c
​

Answer:

d=125-degree since p and q are parallel

b=d=125-degree since b and d are vertically opposite angles

a+d= 180-degree since they lie in straight line

Hence, a=180-125=55-degree

c=a=55-degree since a and c are vertically opposite angle

f=a=55-degree since a and f are alternate angle

e=f=55-degree since e and f are vertically opposite angle

Answer:

Paired difference t test

Step-by-step explanation:

The paired difference t test is a type of statistical test which is used to examine if difference exists in th population mean of two samples. The paired difference test usually involves samples taken within subjects. That is, the sample mean for each set of measurement is taken from the Same subject, In the scenario described above, the subjects which are the 6 veteran runners each wore each of the two shoe brands, this means that two readings were produced by each runner ; one reading for brand A and the other brand B.

The difference between the two readings are taken for each runner and used to perform a hypothesis test:

t = μd/ (s/√n)

s = sample standard deviation ; n = sample size ; μd = mean difference

Answer:

12.75 miles

Step-by-step explanation:

Changing hours to minutes

4 hours 4*60 = 240 minutes

Now we can use a ratio to solve

68 miles            x miles

-------------    = -----------------

240 minutes        45 minutes

Using cross products

68*45 = 240x

Divide each side by 240

68*45 /240 = x

12.75 miles

Answer:

12.75 MILES

Step-by-step explanation:

if he travels 68 miles in 4 we should find how many miles per hour

to find this we divide 68/4 which is 17

So if he is going 17 MPH then to find how far he travels in 45 min we should multiply by 3/4

17 x 3/4 is 12.75

Answer:

See below

Step-by-step explanation:

Feel free to be creative or even to come up with an activity you think your teacher has not seen before.

Liked that. So let's be creative.

Part 1: Record Information

Spend a short amount of time (one to five minutes) doing your activity. Answer the following questions:

1. What was the activity?

I am from Japan and practice Kendo (feel free to search about it). Suppose you are doing suburi. You did 100 joge suburi.

2. How long did you spend doing your activity?

Suppose it took you 5 minutes.

3. How much of the activity did you complete in the time period? (Example: I did 24 sit-ups in one minute.)

You did 100 joge suburi in 5 minutes. It means [tex]\dfrac{100}{5} = 20 \text{ per minute}[/tex]

4. Which of these variables is your dependent variable?

If you want to calculate how much suburi you did in an amount of time [tex]x[/tex], given the time in minutes, we can write the function

[tex]y = f(x)=20x[/tex]

Therefore, the dependent variable is the number of suburis. More precisely it is given by [tex]y[/tex]. On the other hand, the independent variable is [tex]x[/tex], the time.

Considering the example: I did 24 sit-ups in one minute.

sit-ups is the dependent variable and the number of minutes represents the independent variable.

Note: The number of sit-ups will depend on the time. 24 is the coefficient. In this case, the function would be

[tex]g(x) = 24x[/tex]

5. Which one is the independent variable?

The time in minutes.

6. Write a sentence that describes the relationship between the dependent variable and the independent variable. (Hint: Ratio language can help.)

You can write: The ratio of suburi done is 100:5 or 20:1 because for every 1 minute passed you did 20 suburis.  

Part 2: Prepare a Table

Assuming that you could complete the activity at the same rate over different time periods, how much of the activity could you complete in two minutes, three minutes, four minutes, and five minutes? (Note: If you spent two minutes doing your activity, then you should edit the table below and use multiples of 2 up to 10).

You may use the table below for your variables.

Time (minutes)          Quantity of suburi

0                                         0

1                                          20

2                                         40

3                                         60

4                                          80

5                                         100

Part 3: Prepare a Graph

Create a graph to show your relationship. Make sure you include all the parts for a graph and show the data clearly. Include a title for the graph and label the x- and y-axes.

This part I will let it to your. But is is just a linear graph.

Part 4: Write an Equation

Based on your recorded values, write an equation that represents the relationship between the time you spent doing the activity and the amount of the activity you completed. Make sure to define your variables.

[tex]y = f(x)=20x, \forall x \in\mathbb{Z}_{\geq 0}[/tex]

[tex]y: \text{number of suburis}[/tex]

[tex]x: \text{time}[/tex]

7. If you were able to maintain this rate of your activity for 12 minutes, how much of the activity would you be able to complete?

For [tex]x=12[/tex]: [tex]y = f(12)=20\cdot 12 = 240[/tex]

240 suburis

8. How long would it take you to reach 100 for the number of times you did your activity?

5 minutes.

9. Which representation do you believe is the best way to share this information with someone else? This is your opinion. No answer is right or wrong.

The function is the best because it describes all the variables easily.

Answer:

She did nothing wrong

Answer:

a) 0.7

b) 0.3

c) 0

d) 1

Step-by-step explanation:

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

(a) Coke

Out of 10, 7. So

[tex]p = \frac{7}{10} = 0.7[/tex]

(b) fanta

3 out of 10. So

[tex]p = \frac{3}{10} = 0.3[/tex]

(c) neither Coke nor fanta

7 Coke, 3 fanta, so all 10 are either coke or fanta. Thus:

[tex]p = \frac{0}{10} = 0[/tex]

(d) either Coke or fanta​

All 10. Thus:

[tex]p = \frac{10}{10} = 1[/tex]

Answer:

regular hexagon is a answer

Answer:

x=-69/7

Step-by-step explanation:

f (-1) f (x)=(x-10) 3+4

-1=(x-10) 3+4

-1=(x-10) 7

You will multiply 7 by (x-10)

-1=7x-70

Well move the-1 to the right hand side which will become+1 and move the+7x to the left hand side which will become -7x

-7x=-70+1

-7x=-69

So you will divide both sides by-7

-7x/7=-69/7

x=-69/7

Answer:

5^5

Step-by-step explanation:

There are 5 fives being multiplied together.

The expression 5x5x5x5x5 can be written in exponential form as [tex]5^5[/tex].

To express the expression 5x5x5x5x5 in exponential form, follow these steps:

Step 1: Count the number of times the base (5) is multiplied by itself (the number of factors).

Step 2: Write the base (5) followed by the exponent, which is the number of factors from Step 1.

In this case, the base is 5, and it is multiplied by itself 5 times:

5x5x5x5x5 = [tex]5^5[/tex]

So, the expression 5x5x5x5x5 can be written in exponential form as [tex]5^5[/tex].

Answer:

  Sydney is 45

Step-by-step explanation:

Let s represent Sydney's age. Then Devaughn's age is (s-14). The total of their ages is ...

  s +(s -14) = 76

  2s = 90 . . . . . . simplify, add 14

  s = 45 . . . . . . . divide by 2

Sydney's age is 45.

___

Check

  Devaughn's age is 45 -14 = 31. Their age total is 45 +31 = 76, as required.

Answer:

x + (x - 14) = 76

2x - 14 = 76

2x = 90

x = 45

Sydney is 45

45 - 14 = 31

Devaughn is 31

A line is a one-dimensional shape that is straight, has no thickness. The length of the sides AB is 13 units.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.

Given Points A, B, and C are collinear, BC = 2x+1, AB = 4x-3, and AC is 7x- 6. Since the three points are collinear therefore, the sum of AB and BC will be equal to AC. Therefore, we can write,

AB + BC = AC

4x - 3 + 2x + 1 = 7x - 6

6x - 2 = 7x - 6

-2 + 6 = 7x - 6x

4 = x

Now, since the value of x is 4, the measurement of AB is,

AB = 4x - 3 = 4(4) - 3 = 16 - 3 = 13 units

Hence, the length of the sides AB is 13 units.
