The number of counters is an illustration of a linear function
The number of counters that land on yellow is: [tex]f(n) = 128 - \frac 12n\\[/tex]The students need 254 trials to have one yellow side upHow to determine the equation
The number of counters is given as:
Count = 128
Each counter is two-colored (i.e. 1/2 yellow and 1/2 red)
So, the equation that represents the number of counters that land on yellow is:
[tex]f(n) = 128 - \frac 12n\\[/tex]
The number of trials to have one yellow side upWhen one yellow side is up, we have:
f(n) = 1
So, we have:
[tex]1 = 128 - \frac 12*n[/tex]
Subtract 128 from both sides
[tex]-127 = - \frac 12*n[/tex]
Multiply both sides by -2
[tex]n =254[/tex]
Hence, the student needs 254 trials to have one yellow side up

For the data set 9, 13, 14, 15, 15, 18, the mean is 14. What is the mean
absolute deviation?
A. The mean absolute deviation is 6.
B. The mean absolute deviation is 2.
C. The mean absolute deviation is 12.
ОО
D. The mean absolute deviation is 14.
Answer:
its B if you are doing the big test
Step-by-step explanation:
The mean absolute deviation is 2.
What is mean absolute deviation?'The mean absolute deviation is the mean distance between each data value and the mean of the data set.'
According to the given problem,
Mean of the given data set = 14
Absolute deviation of mean from each data point,
⇒ ( 9 - 14 ) = 5
⇒ ( 13 - 14 ) = 1
⇒ ( 14 - 14 ) = 0
⇒ ( 15 - 14 ) = 1
⇒ ( 15 - 14 ) = 1
⇒ ( 18 - 14 ) = 4
Mean absolute deviation = [tex]\frac{5+1+0+1+1+4}{6}[/tex]
= [tex]\frac{12}{6}[/tex]
= 2
Hence, we can conclude, the mean absolute deviation of the given data set is 2.

Fully explain two different ways you could use transformations to go from shape a to shape B
Answer:
1. rotation 180 degrees to the right (or left), 2. reflect shape A over the horizontal line at the bottom of the shape, then reflect the result over the short vertical line that goes through the point where the shapes meet.
Step-by-step explanation:
See the attached image. Method 2 calls for two reflections, one across the red line, the second across the yellow line.
P.S. I added an image that shows the shape reflected across the red line. Finally, flip THAT horizontally.

Facial shaving brushes are either bulb-shaped or fan-shaped. An experiment is to be conducted to determine whether the lather thickness is the same for both types of shaving brushes. In previous studies, it was determined that shaving brush size (small, medium, large) is associated with lather thickness, but shaving brush type (Wolf Whiskers, Maggard Razors, Frank Shaving, and so on) is not associated with lather thickness. How could the experiment BEST be conducted?
a) By blocking on shaving brush size
b) By blocking on shaving brush type
c) By blocking on shaving brush shape
d) By blocking on lather thickness
e) Without blocking
Answer:
a) By blocking on shaving brush size
Step-by-step explanation:
You block on the variable that the researchers think matters.
The experiment can BEST be conducted by blocking on shaving brush size
What is the reason behind the experiments?An experiment is designed to verify your hypothesis. If your theory is valid, every time a scientific experiment has been conducted, it has the potential to be true.
In this given experiment a technique is used to verify or disprove a theory, as well as assess the effectiveness or likelihood of something that has never been tried before. Experiments show what happens when a specific factor is modified, which sheds light on cause-and-effect relationships.
Since, lather thickness and shaving brush size are related, changing the brush size could have an impact on the experiment's findings.
Therefore, The experiment can be best carried out by limiting the size of the shaving brush.

A pediatrician wishes to recruit 5 couples, each of whom is expecting their first child, to participate in a new natural childbirth regimen. The probability that a randomly selected couple agrees to participate is 0.2. What is the distribution to model the number of couples who do not agree until 5 are found who agree to participate
Answer:
Inverse binomial distribution
Step-by-step explanation:
For each couple, there are only two possible outcomes. Either they agree to participate, or they do not. The probability of a couple agreeing to participate is independent of any other couple accepting. This means that we take the binomial distribution as a basis to solve this question.
However, we want to find the number of trials needed to have a number of successes, in this case 5, that is, we do not have a fixed number of trials, which means that the inverse binomial distribution is used, and is the answer to this question.
