The linear speed of one of the cars is 7.75 feet per second
The cars (seats) of a Ferris wheel are positioned 74 feet from its center.
The radius, r = 74 feet
The Ferris wheel makes 4 revolutions every 4 minutes
Number of revolutions per minute = 1
Angular speed, w = 1 rev/min
Angular speed, w = 0.10472 rad/sec
The relationship between the linear speed (v), and the angular speed (w) is:
v = wr
Substitute w = 0.10472 and r = 74 feet into the formula:
v = 0.10472 x 74
v = 7.75 feet per second
The linear speed of one of the cars is 7.75 feet per second

Answer:
And for the other case if we use the z score and the complement rule we have:
And we can find the probability of interest like this:
And replacing we got:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:
We assume that the distribution is
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we find the individual probabilities we got:
And for the other case if we use the z score and the complement rule we have:
And we can find the probability of interest like this:
And replacing we got:
Answer:
The game developer tested by 24 participants and these 24 participants were divided evenly between the treatments and the required total number of possible replications combinations is 4.
Step-by-step explanation:
<em>The Concepts and reason
</em>
The ANOVA can be used to analyze the data obtained from experimental or observational studies. A factor is a variable that the experimenter has taken for investigation.
A treatment is a level of a factor, and its experimental units are the objects of interest in the experiment. The variation between treatments groups captures the effect of the treatment and the variation within treatment groups represents random error not explained by the experimental treatments.
The replication means an independent repeat of each factor combination.
<em>Fundamentals
</em>
The formula for replications is: Number of participants/number of cells
The total number of participants is: 24
The number of cells is: 6
The total number of participants in the game is 24 and the number of possible combination cells is 6
so,
Number of replications: Number of participants/number of cells
which is 24/6= 4
Therefore the number of replications is 4.
Answer:
all 4 meals equal $20.95
Step-by-step explanation:
4 sandwiches = $2.59 each
4 hashbrowns = $1.10 each
4 orange juice = $1.25 each
sales tax = 6%
now you have two options you could either add all of the one meal prices together or you could do how much it would cost for the each individually
adding one meal
2.59 + 1.10 + 1.25 = 4.94
4.94 x 4 = 19.76
adding all the items individually
2.59 x 4 = 10.36
1.10 x 4 = 4.40
1.25 x 4 = 5.00
10.36 + 4.40 + 5.00 = 19.76
now if the sales taxes
19.76 x 0.06 = 1.19
now sales taxes plus all the items
19.76 + 1.19 = 20.95
