Two students are comparing scientific experiments to investigations. They came up with the following ideas.
Student A: Testing plant growth in different types of soils
Student B: Comparing the water level in a lake during different times of the year Which student gave an example of a scientific experiment? (5 points)
A: Student A because it requires experimental and control groups
B; Student B because it requires a hypothesis
C: Student A because it is preferably done in natural settings
D: Student B because it is preferably done across a long period of time
Answer:
A is the correct answer.
Step-by-step explanation:
In experiment we require a controlled variable which is the constant in example A that is the plant we intend to put into the soil. In example B there's no such thing as controlled variable, so we can't expect the position of the water level. the water level is so unpredictable since tides or tsunami might change the result.
Answer:
A
Step-by-step explanation:
Scientific experiments need to have an independent and a dependent variable. Scientists can manipulate the independent variable. A should be the correct answer because it mentions what I just said. All scientific experiments need to have a control and experimental group. Therefore, student A and the answer A are correct.

multiply 113 by 3 and thats the amount of paper Tommy used to make three 6 inch sandwiches, then add 223. And thats the answer.
A basketball player made 40 out of 50 free throws in last week's games.
a) Find the player's free-throw
percentage. (I believe it's 80%)
b) If the player averages eight free throws
per game, how many of them should she expect to make?
Answer:
a) The player's free-throw percentage is 80%
b) If the player averages 8 free throws per game, she should expect to successfully make 6.4 or about 6.
Step-by-step explanation:
Make the percent (80%) a fraction, 80/100.
Since the total amount of throws she makes is 8, put 8 as the denominator (bottom of the fraction) and an x as the numerator (top of the fraction) since the amount of throws she will make is unknown.
Because 80/100 is her free throw percentage, it should be consistent with the 8 she throws each game. Due to that, the x/8 is equal to the 80/100.
With the equation 80/100 = x/8, multiply diaganolly and you should get 640/100x.
When you divide that, you get 6 40/100 or 6.4 free throws made per every 8 throws. Because you can't make 0.4 of a throw, you round therefore making it 6.
I hope this helps!!! :)
a) To find the player's free-throw percentage, divide the number of successful free throws (40) by the total number of attempted free throws (50) and multiply by 100.
Free-throw percentage = (Successful free throws / Total attempted free throws) * 100
= (40 / 50) * 100
= 0.8 * 100
= 80%
Therefore, the player's free-throw percentage is 80%.
b) If the player averages eight free throws per game, we can use the free-throw percentage to determine the expected number of successful free throws.
Expected successful free throws = (Free-throw percentage / 100) * Number of attempts
Number of attempts = 8 (since the player averages eight free throws per game)
Expected successful free throws = (80 / 100) * 8
= 0.8 * 8
= 6.4
Therefore, the player should expect to make approximately 6 to 7 free throws per game.

Lucy earns 52 dollars each week working part-time at a bookstore. She earns one additional dollar for each book that she sells.
Let 'A' be the amount (in dollars) that Lucy earns in a week if she sells 'B' books.
Write an equation relating A to B . Then use this equation to find the amount of money Lucy earns if she sells 15 books.
Answer:
A = B + 52
Step-by-step explanation:
A is the total amount each week. 52 is the initial amount that she earns each week. Then, B represents the amount of books she sells. So, 15 books can be represented by
A = 15 + 52 = 67
Answer:
$67 earnings
Step-by-step explanation:
1. Let A = $ earned for books sold
2. Let B = # of books sold
3. Let A = money earned
4. Equation: A = 52 + 1B
5. Solution: $67 = 52+ 1(15)

Step-by-step explanation:
- 36 + ( - 4 / 9 )
= - 36 - ( 4 / 9 )
= - 36 ( 9 / 9 ) - 4 / 9
= ( - 36 x 9 ) / 9 - ( 4 / 9 )
= ( - 324 / 9 ) - ( 4 / 9 )
= ( - 324 - 4 ) / 9

The graph represents function 1 and the equation represents function 2:
A graph with numbers 0 to 4 on the x-axis and y-axis at increments of 1. A horizontal straight line is drawn joining the ordered pairs 0, 3 and 4, 3.
Function 2
y = 3x + 1
How much more is the rate of change of function 2 than the rate of change of function 1?
1
2
3
4
Answer:
its c
Step-by-step explanation:
Answer:
The rate of change of function 1 = 0 The rate of change of the function 2 = 3
Therefore, the rate of change of function 2 is 3 more than the rate of change of function 1.
Hence, option C is true.
Step-by-step explanation:
Function 1
A horizontal straight line is drawn joining the ordered pairs (0, 3) and (4, 3).
Given the points
(0, 3)
(4, 3)
It means
at x = 0, y = 3
at x = 4, y = 3
Since the y-values are same, it means the points lie on a horizontal.
The rate of change or slope of a horizontal line is zero because it does not rise vertically ( i.e. y₁ - y₂ = 0).
Therefore, the rate of change of function 1 = 0
Function 2
y = 3x+1
comparing with the slope-intercept form
y = mx+b
here m is the rate of change or slope and b is the y-intercept
so the rate of change of the function 2 = m = 3
Conclusion:
The rate of change of function 1 = 0
The rate of change of the function 2 = 3
Therefore, the rate of change of function 2 is 3 more than the rate of change of function 1.
Hence, option C is true.

On Monday, it snowed 30 inches in 16 hours. On Thursday, it snowed 21 inches in 6 hours. On which day did it snow at a greater rate each hour? How much more per hour?
Answer:
It snowed more on thursday because
Step-by-step explanation:
you just basically divide 30 by 16 30/16 = 1.9 (simplified)
Then you divide 21 by 6 21/6 = 3.5
Answer/ Explanation:
It snowed more on thursday because when you divide 30 by 16 you get 1.9 inches an hour, then I divided 21 by 6 you get 3.5 inches of snow an hour. So therefore on thursday it snowed more every hour.
(I don't care if you use my words for the explanation)
The rate of snow deposition on Thursday is 1.625 inches per hour more than that on Monday.
What is the rate of change?Rate of change is defined as the change in value with rest to the time is called rate of change.
here,
The rate of snow deposition is given as,
Rate = amount of snow/time
On Monday, it snowed 30 inches in 16 hours.
Rate = 30 / 16 = 1.875 inch per hour
On Thursday, it snowed 21 inches in 6 hours.
Rate = 21 / 6 = 3.5 inch per hour
Difference in rate = 3.5 - 1.875
= 1.625 inches per hour
Thus, the rate of snow deposition on Thursday is 1.625 inches per hour more than that on Monday.

Answer:
D) -5 1/4
Step-by-step explanation:
In this problem there is -3/4 foot change every year and you are trying to see how much changes over 7 years. That means you are multiply the 7 by -3/4. To do that you need to change the 7 into a fraction.
7= 7/1, now you are going to mulitpy the two fractions.
This line represents the numerators: 7 times -3= -21
This line represents the denominators: 1 times 4 = 4
Now that we know our fraction is -21/4 we simplify.
The simplest form you can get is -5 1/4.
