Question;
1) The shaded plants set has greater variability because more data is clustered around the median.
2) The sets are equally variable because the ranges of the data sets are equal.
3) The full sun plants set has greater variability because the IQR for full sun plants is greater.
Answer:
The correct option is;
3) The full sun plants set has greater variability because the IQR for full sun plants is greater
Step-by-step explanation:
To answer the question, we present the dot plot as follows;
Heights of Shaded plants (inches)
0 4 3 2 0 0 1
0 1.5 2 2.5 3 3.5 4 4.5
We calculate the five numbers as follows;
Max = 4.5
Min = 2
1st quartile = (10+1)/4 th term = 2
2nd quartile (Median) = (10+1)/2 th term = 2.5
3rd quartile = 3×(10+1)/4 th term = 3
Interquatile range (IQR) = Q₃ - Q₁ = 3 - 2 = 1
Where:
Q₁ = 1st quartile
Q₃ = 3rd quartile
Heights of Full Sun plants
0 1 0 2 0 4 3
1.5 2 2.5 3 3.5 4 4.5
We calculate the five numbers as follows;
Max = 4.5
Min = 2
1st quartile = (10+1)/4 th term = 3
2nd quartile (Median) = (10+1)/2 th term = 4
3rd quartile = 3×(10+1)/4 th term = 4.5
Interquatile range (IQR) = Q₃ - Q₁ = 4.5 - 3 = 1.5
The interquartile range, IQR, is a measure of variability
Therefore, the full sun plants set has greater variability because the IQR for full sun plants is greater.

The members of a wheelchair basketball league are playing a benefit game to meet their fundraising goal of $900. Tickets cost $15 and snacks cost $6.
The question is incomplete:
The members of a wheelchair basketball league are playing a benefit game to meet their fundraising goal of $900. Tickets cost $15 and snacks cost $6.
a. Write a linear equation that describes the problem
b. Graph the linear equation.
c. If the team sells 50 tickets, how many snacks does it need to sell to reach the goal?
Answer:
a.15x+6y= 900
b. The graph is attached.
c. 25
Step-by-step explanation:
a. From the information provided, the linear equation has to express that the number of tickets multiply for its price plus the number of snacks multiply for its price would be equal to $900:
15x+6y= 900
x= number of tickets
y= number of snacks
b.
When x= 0:
15(0)+6y= 900
y=900/6= 150
When y=0
15x+6(0)= 900
x=900/15= 60
With these points, you can graph the linear equation and the image is attached.
c. You have to replace the value of x in the equation and isolate y:
15x+6y= 900
15(50)+6y= 900
750+6y=900
6y= 900-750
6y= 150
y= 150/6
y= 25
You need to sell 25 snacks to reach the goal.

What does it mean
by round to the nearest degree.
Answer:
Rounding up to the nearest degree is equivalent to rounding up to the nearest whole number (or integer)
Step-by-step explanation:
Any value between degrees above .5 is rounded up to the next degree, so for instance:
30.4 --> 30
30.5 --> 31
30.999 --> 31
31 --> 31
31.499 --> 31
Rounding values expressed in degrees and minutes is similar to rounding decimals.
What is mean by rounding off?Rounding numbers refers to changing a number's digits such that it approximates a value. The provided number is more simply represented by this value. For instance, 700,000 rather than 698,869 could be used to express a town's population.
We know that;
Rounding values expressed in degrees and minutes is similar to rounding decimals.
However, because there are 60 minutes in a degree, the half way point is 30. If the number of minutes is less than 30, we round down to the nearest degree. If the number of minutes is 30 or more, we round up to the nearest degree.

Solve for x. *
(5x + 13)
(9x - 31)
Answer:
x=11
Step-by-step explanation:
5x+13=9x-31
subtract 9 from both sides.
-4x+13=-31
you want to isolate the x value so subtract 13 from both sides.
-4x=-44
now divide both sides by -4.
x=11
The solution for the variable x for given the equation (5x + 13) = (9x - 31) is equal to x = 11.
For the equation (5x + 13) = (9x - 31)
Expand the equation: 5x + 13 = 9x - 31
Combine like terms: 13 = 4x - 31
Isolate x: 4x = 44, x = 11
Therefore, the value of the variable x in the given equation is x = 11.

Answer:
3.2
Step-by-step explanation:
First, you have to arrange them in proper numerical order (least to greatest).
84, 88,90,92,96
Next, find the mean by adding them all up and dividing them by 5.
84 + 88 + 90 + 92 + 96 = 450
450 divide by 5 equals 90.
Now, that we have our mean, we have to subtract it from each of the numbers in the data set. Remember this is absolute so there is no negatives.
84 - 90 = 6
88 - 90 = 2
90 - 90 = 0
92 - 90 =2
96 - 90 = 6
Next, line them up again.
2,2,6,6
Find the mean of them:
2 + 2 + 6 + 6 = 16
16 divided by 4 is 4.
Therefore, our answer would be the MAD is 4.0

Caleb is a junior at JA Enterprise High School and plays rugby on the school team. He has a part-time job at a local fast-food restaurant and works 20 hours a week for $7.60 an hour. His gross monthly income is $608.00, and his take-home pay is $501.64. In his spare time, Caleb walks a dog belonging to an elderly neighbor. He earns an additional $40 per month for that chore. What is Caleb's net monthly income? Remember net income is your take home pay.
Answer:
$541.64
Step-by-step explanation:
Caleb's take Home Pay from the Restaurant =$501.64
He earns an additional $40 per month for dog-walking.
Therefore,
Caleb's net monthly income =$501.64+40 =$541.64
Final answer:
Caleb's net monthly income is $541.64 after factoring in his take-home pay and additional earnings.
Explanation:
Caleb's net monthly income is calculated by subtracting his take-home pay from his additional earnings from walking the dog:
Caleb's take-home pay = $501.64
Additional earnings from walking the dog = $40
Net income = Take-home pay + additional earnings = $501.64 + $40 = $541.64

Horizontally - Indicates that the movement is from either left to right.
Positive Direction - To the right, or up; in this case, it means to the right.
4 units - Self-explanatory, but make sure you know this is done from the already given coordinate, (-1, 3)!
Answer:
(3, 3)
Step-by-step explanation:
Translating horizontally means to move left or right along the x-axis. To move horizontally in a positive direction means to move right. Since our x-value in the coordinate is -1, we know we must add 4 to it to get our answer.
An audiometer produces a pure tone with a frequency f of 1200 hertz (cycles per second). The maximum pressure P produced from the pure tone is 5 millipascals. Write a sine model that gives the pressure P as a function of the time t (in seconds). Assume P=0 when t=0.
The pressure P as a function of time t can be modeled using the sine function. The maximum pressure is 5 millipascals. The wavelength, frequency, and speed of the sound wave can be calculated using formulas.
Explanation:The sine model that gives the pressure P as a function of time t is:
P(t) = 5 millipascals * sin(2π * 1200 * t)
Maximum change in pressure: The maximum change in pressure is 5 millipascals.
Wavelength: The wavelength of the sound wave can be calculated using the formula: wavelength = speed / frequency. Since the speed of sound in air is approximately 343 meters per second, the wavelength is approximately 0.285 meters.
Frequency: The frequency of the sound wave is 1200 hertz (cycles per second).
Speed of the sound wave: The speed of the sound wave can be calculated using the formula: speed = wavelength * frequency. Using the values we have, the speed of the sound wave is approximately 343 meters per second.
Final answer:
The sine model that gives the pressure P as a function of time t for an audiometer producing a pure tone at 1200 Hz with a maximum pressure of 5 millipascals is P(t) = 5 · sin(2π · 1200t).
Explanation:
To write a sine model that gives the pressure P as a function of the time t for a sound wave produced by an audiometer, we can use the standard form of a sine function for a periodic wave:
P(t) = Pmax · sin(2πft + φ)
Since we are given that Pmax is 5 millipascals, the frequency f is 1200 hertz, and P=0 when t=0 (which implies that the initial phase shift φ is zero), we can plug these values into the sine model to get:
P(t) = 5 · sin(2π · 1200t)
Here, we converted the maximum pressure from millipascals to pascals, and since the sine of 0 is 0, we have a phase shift of 0 radians, simplifying the equation.
