First term, a = 6
Common difference, d = 4
Using the formula :
an = a + (n - 1) d
an = 6 + (n - 1) 4
an = 6 + 4n - 4

Fiona is paid $11 an hour to work as a referee. The amount of money he earns depends on how many hours he works. Which is a dependent variable, and which is an independent variable?
Answer:
Number of hours worked = independent
Money earned = dependent
Step-by-step explanation:
The money earned is dependent because "the amount of money he earns depends on how many hours he works." Since the money earned is dependent, the number of hours worked is independent.
We can also think of it another way. You can pick how many hours you work (theoretically) so this is indepdent. The amount of money earned depends on the hours you worked.
Summary:
Looking at the wording, we can answer the question with the following:
Number of hours worked = independent
Money earned = dependent

Mario collects seashells and sells them to tourists. The function s(t) approximates how many seashells Mario collects per hour. The function W(h) represents the number of hours per week Mario spends collecting seashells. What are the units of measurement for the composite function s(W(h))? seashells over hour seashells over week hours over week weeks over seashell
Answer:
seashells/week
Explanation:
With the given the function s(h) being seashells per hour, and the function W(h) being the number of hours per week, we can say that the compostie function s(W(h)) is finding the number of seashells per week.
(I've also taken the test and this was the correct answer.)

Step-by-step explanation:
Jessie wants to run a simulation of 10 trials to determine the probability of her picking at least one green marble in her next two picks. She will replace the marble after the first pick. Explain how Jessie can conduct a simulation using random digits from 0-9.
The simulation using random digits is an illustration of sample space and probability
How to run the simulation using random digits?From the question, we understand that the simulation is to determine the probability that she picks at least one green marble in her next two picks.
One of the ways this can be done is as follows:
Represent the green marbles with digits 0 - 4 Represent the other marbles with digits 5 - 9The above ensures that the probability of picking a green marble in each selection is 0.5 and the probability of not picking a green marble in each selection is also 0.5 i.e. the experiment is fair
Next, is to run a simulation of 10 trials.
Take for instance, the result of the simulation is as follows:
00 65 36 48 55
19 34 87 13 90
The number of outcomes that has at least one of digits 0 - 4 represents the required outcome i.e. picking at least one green marble
From the simulation result, the number of outcomes is
At least 1 green marble = 7
Number of trials = 10
So, the probability of picking at least a green marble is:
P = 7/10
P = 70%
Note that there are several other ways the simulation can be done; this is just one of them

Step-by-step explanation:
It took Fred 12 hours to travel over pack ice from one town in the arctic to another town 360 miles away. During the return journey, it took him 15 hours. Assume the pack ice was drifting at a constant rate, and that Fred’s snowmobile was traveling at a constant speed relative to the pack ice. What was the speed of Fred’s snowmobile?
Using the relation between velocity, distance and time, it is found that the speed of Fred’s snowmobile was of 27 miles per hour.
What is the relation between velocity, distance and time?
Velocity is distance divided by time, hence:
[tex]v = \frac{d}{t}[/tex]
It took Fred 12 hours to travel over pack ice from one town in the arctic to another town 360 miles away, when the ice was drifting in the same direction, hence:
[tex]v_i + v_s = \frac{360}{12}[/tex]
[tex]v_i + v_s = 30[/tex]
[tex]v_i = 30 - v_s[/tex]
In the return trip, with the ice in opposite direction he took 15 hours, hence:
[tex]v_s - v_i = \frac{360}{15}[/tex]
[tex]v_s - v_i = 24[/tex]
Since [tex]v_i = 30 - v_s[/tex]:
[tex]v_s - 30 + v_s = 24[/tex]
[tex]2v_s = 54[/tex]
[tex]v_s = 27[/tex]
The speed of Fred’s snowmobile was of 27 miles per hour.

What is a scatterplot?A scatterplot is a type of graphical display that is used to represent the relationship between two continuous variables.
In a scatterplot, each point represents the values of the two variables, with one variable being plotted along the x-axis and the other variable being plotted along the y-axis.
The position of each point on the graph represents the values of both variables for that particular observation.
We have,
To determine the best equation to represent the data, we will first plot the points on a graphing calculator:
Day Snow Depth
1 47
2 29
3 20
4 10
5 7
6 5
7 1.5
Now,
Based on the scatter plot of the points, it appears that a quadratic equation would best represent the data.
Using the quadratic regression feature on the graphing calculator, we obtain the following equation:
Snow Depth = -8x² + 93x - 56
Rounding to the nearest integer, the final equation that best represents the data is:
Snow Depth = -8x² + 93x - 56
Thus,

the sum it two numbers is 82.5. Their difference is 12.9. what are the numbers
Explaination :
Let us assume the unknown two numbers as an variable. Here we are assuming it as a and b.
★ According to the question,
Sum of those assumed two numbers is 82.5.
a + b = 82.5
Also it is given that difference of both the two numbers is 12.9.
a - b = 12.9
From the given information we got two equations,
a + b = 82.5 (Equation No 1)
a - b = 12.9 (Equation No 2)
So we would solve them and get the value of a and b.
★ From Equation No 2 :
a = 12.9 + b
★ In Equation No 1 :
Substituting the value of a which we got above here,
(12.9 + b) + b = 82.5
12.9 + b + b = 82.5
12.9 + 2b = 82.5
2b = 82.5 - 12.9
2b = 69.6
b = 69.6 / 2
b = 34.8
★ Therefore,
Value of b is 34.8★ Finding out value of a :
a = 12.9 + b
a = 12.9 + 34.8
a = 47.7
