In order to have a great experiment and great data for analyzing you must have the best experiment design possible.Experiment design is the process of organizing the experiment properly to ensure that the right type and amount of data are available to answer the questions of interest. Some of the tips to follow in order to have good experimental design are:
-Choose a topic that will interest and challenge you.Do not pick a broad topic.
- Spend a lot of time gathering background research.
- Predict the outcome of your experiment with the help of equation.
-Keep a detailed and up-to-date lab notebook with the results.
- Do as many trials as possible .
- During the experiment, do not get discouraged if you run into a lot of problems..

What volume error (in mL, round to the nearest tenth) would occur in the measuring of 4 mL of a liquid ingredient if the imprope

zmey [24]

Answer:

0.5 mL

Step-by-step explanation:

If the device wasn't properly calibrated, in volume the number can be estimated with a 3 rule:

100%------4mL

12%-------x=12*4/100=0.48≈0.5mL rounding to the nearest tenth

If x varies directly as y, and X = 24 when y= 21, Find x when Y=6

Ne4ueva [31]

Answer:

x = 48/7

Step-by-step explanation:

There's two good ways to do this problem.

Option 1:

Translate "x varies directly as y" into the equation y=kx

Then you have to find k. After you "reset" your y=kx equation, fill in k and then solve for x. See image.

Option 2:

Translate "varies directly" into a proportion, which is two fractions equal to each other:

x/y = x/y

Fill in the three numbers given and cross multiply and solve to find the fourth number. See image.

I NEED HELP PLEASE, THANKS! :) Determine the zeros for and the end behavior of f(x) = x(x – 4)(x + 2)^4.

Amiraneli [1.4K]

Answer: a) zeros: x = {0, 4, -2}

b) as x → ∞, y → ∞

as x → -∞, y → ∞

Step-by-step explanation:

I think you mean (a) find the zeros and (b) describe the end behavior

(a) Find the zeros by setting each factor equal to zero and solving for x:

x (x - 4) (x + 2)⁴ = 0

x = 0 Multiplicity of 1 --> odd multiplicity so it crosses the x-axis

x = 4 Multiplicity of 1 --> odd multiplicity so it crosses the x-axis

x = -2 Multiplicity of 4 --> even multiplicity so it touches the x-axis

Degree = 6

(b) End behavior is determined by the following two criteria:

Sign of Leading Coefficient (Right side): Positive is ↑, Negative is ↓
Degree (Left side): Even is same direction as right side, Odd is opposite direction of right side

Sign of the leading coefficient is Positive so right side goes UP

as x → ∞, y → ∞

Degree of 6 is Even so Left side is the same direction as right (UP)

as x → -∞, y → ∞

The parent cosine function is transformed to create the function . which graphed function has the same amplitude as function m?

Shkiper50 [21]

Based on the graph given, the option that will show the same amplitude as function m is graph D.

<h3>Which graphed function is this about?</h3>

The cosine function is seen as:

f(x) = A*cos(kx) + M

And the functions are:

A stands for amplitude,
k is angular frequency,
M is the midline.

When the function is m(x) = -2*cos(x+π).

The absolute value of the amplitude will be 2*|-2| = 4

Therefore, the option that can have the requirement above is graph D.
