Answer:

89 meters per second.

Step-by-step explanation:

That is quite fast!

First, we are given that in 9 sec our falcon has flown 801 meters, let's write an equation for that:

9s = 801

So in order to get s, we divide each side by 9.

Solve!

s = 801/9

s = 89

Answer:

C) 2/7, 1/2, 5/6, 4/2

Step-by-step explanation:

Answer:

The mean is of 45.

The standard deviation is 2.28.

Step-by-step explanation:

The mean is the sum of all values divided by the number of values.

The standard deviation is the square root of the sum of the difference squared between each value and the mean, and divided by the number of values.

Mean:

[tex]M = \frac{45 + 48 + 42 + 47 + 43}{5} = 45[/tex]

The mean is of 45.

Standard deviation:

[tex]M = \sqrt{\frac{(45-45)^2 + (48-45)^2 + (42-45)^2 + (47-45)^2 + (43-45)^2}{5}} = 2.28[/tex]

The standard deviation is 2.28.

Answer: 62

Step-by-step explanation: Set up your equation

Check your work. 62+21=83. 2(62)= 124. 124-41=83. Both equations equal 83, so the solution is correct.

I'll do the first four problems to get you started

====================================================

Problem 15

-----------------

Explanation:

The price dropped by $60, since 150-90 = 60. This is the discount, which is the amount you save. Divide this over the original price ($150) and we get 60/150 = 0.40 = 40%

Therefore, the price has been reduced by 40%. If we take 40% of 150, then 0.40*150 = 60 showing that 40% of $150 is 60 dollars. This matches up with the discount value mentioned earlier. So it helps verify the answer.

====================================================

Problem 16

-----------------

Explanation:

The pay raised by 12-10 = 2 dollars. So the percent increase is 2/10 = 0.20 = 20%

Note how 20% of 10 = 0.20*10 = 2 is the pay raise amount; meaning that 2 is 20% of 10.

====================================================

Problem 17

-----------------

Explanation:

I'll use a formula this time, but we could follow the same idea as the previous problems. This is to give another approach.

A = old value = 8

B = new value = 12

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (12-8)/8 ] * 100%

C = (4/8)*100%

C = 0.50*100%

C = 50%

50% is the same as half of the value. Note how half of 8 is 4, ie 50% of 8 = 0.50*8 = 4. So this is the amount of increase when going from 8 to 12.

Side note: The "B-A" portion in the numerator represents the change in value. We divide this change over the original amount "A" and then multiply by 100% to get the percent change we're after.

====================================================

Problem 18

-----------------

Explanation:

I'll use the formula again

A = old value = 3.00

B = new value = 2.28

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (2.28-3.00)/3.00 ] * 100%

C = (-0.72/3.00)*100%

C = -0.24*100

C = -24%

The negative percent change means we have a percent decrease. So we have a 24% decrease. Since your teacher is asking about how much the percent reduction is, we'll write the positive version of this percentage.

Problems 19 through 22 will follow the same ideas as shown in the previous problems.

Answer:

D

Step-by-step explanation:

Answer: The three methods are the treatments and the response is the score achieved on the quiz.

Step-by-step explanation:

The three techniques are the treatments, and the results are the final score.

what is response variable in the experiment?

The researcher predicts that a variable will change if the controlled variable changes; this variable is known as a responsive variable. A dependent variable is another name for a responsive variable.

Solution:

Three methods are assigned for teaching mathematics.

Randomly ten students are assigned to each of the method.

There scores are then recorded on a quiz.

It is clear that the response will be the score card of the students either scoring high marks or not being able to clear it.

And the treatments are three for if the student is not able to understand any of the method.

Hence the three methods serve as treatments, and the outcomes determine the final grade.

OK ITS OK IM GOD CALM DOWN

Answer:

Step-by-step explanation:

(1)

If she got 10 answers right, she got 5 * 10 = 50 marks before anything was deducted.

Since she wound up with 30 marks, she lost 50 - 30 = 20 marks. If you don't feel comfortable with this, call it -20

Each incorrect answer cost her -2 marks.

Divide -20 /-2 = 10

She has answered 10 questions incorrectly.

(ii)

5x - 2y = 44

x + y = 13             Multiply this equation by 2

2x + 2y = 26

Rewrite the first and third equations

5x - 2y = 44

2x + 2y = 26      Add  

7x = 70              Divide by 7

x = 70/7

x = 10

So 10 questions were answered correctly

x + y = 13

10 + y = 13

y = 3

Answer

10 were answered correctly

3  were answered incorrectly
