what is the mode of the following data: 47 republicans, 49 democrats, and 52 independents?
Answer:
There is no mode for the following data.
Step-by-step explanation:
This is because the mode is the value which occurs most frequently in a data set. yet there is not a piece of data that appears the most frequently.
The mode of this data set is the Independents.
The mode is a statistical term that refers to the value that appears most frequently in a data set. In this case, you have provided data on the number of Republicans, Democrats, and Independents. There are 47 Republicans, 49 Democrats, and 52 Independents.
To determine the mode, we simply look for the highest count among the three groups. In this case, we can see that the group with the highest count is the Independents with a count of 52.
Therefore, the mode of this data set is the Independents. This tells us that Independents are the most frequent group in this particular data set. Remember, the mode is just one way to describe the central tendency of data and should be considered alongside other measures like the mean and median for a more comprehensive understanding of the data distribution.

What is the measure of AC?
If R= [0,3] x [0, 4] then use the mid point rule with m = 3 and n = 2 subdivisions to estimate || sin(ay?)da, where m is the number of z-axis subdivisions and n is the number of y-axis subdivisions. You need not simplify your answer.
Using the midpoint rule with m = 3 and n = 2 subdivisions, the estimate of || sin(ay?)da over the rectangle R = [0,3] x [0,4] is approximately 16.219.
The midpoint rule is a numerical integration method that approximates the value of a definite integral by dividing the integration region into smaller subintervals and approximating the integrand by its value at the midpoint of each subinterval. In this case, we are integrating sin(ay?) over the rectangle R = [0,3] x [0,4], which means that we need to divide the rectangle into m*n subrectangles, each with width 3/m and height 4/n. Then, we can approximate the integral by summing up the contributions of the midpoints of each subrectangle.
In this case, we have m = 3 and n = 2, which means that we need to divide the rectangle into 6 subrectangles, each with width 1 and height 2. The midpoints of the subrectangles are then (0.5,1), (1.5,1), (2.5,1), (0.5,3), (1.5,3), and (2.5,3). Evaluating the integrand at each midpoint, we get the values sin(a*0.5)2, sin(a1.5)2, sin(a2.5)2, sin(a0.5)2, sin(a1.5)2, and sin(a2.5)*2. Summing up these values and multiplying by the area of each subrectangle (2), we get the estimate of 16.219.

The perimeter of the figure is equivalent to 8x + 8
Perimeter of a figureThe given diagram is a composite figure. The perimeter of the figure is the sum of all the sides.
Taking the sum of all the sides
Sum = 3x - 2 + (x + 6) + (x + 5) + x + (x + 2) + (x - 3)
Sum = (3x + x + x + x + x + x) - 2 + 6 + 5 + 2 - 3
Sum = 8x + 4 + 7 - 3
Sum = 8x + 8

Mr. Lee is a hotdog and drink vendor at a baseball game. Hot dogs are 3.50 and drinks are 1.50. If Mr. Lee sold enough to make 450 dollars on Monday. He remembers that on Monday he sold three times as many drinks as he did hot dogs. How many hot dogs and how many drinks did Mr. Lee sell on Monday?
Answer:
33 hotdogs and 225 drinks on Monday
Step-by-step explanation:
We would use the ratio of 1:3 hotdogs to drinks
Split the ratio in 450 and we get 112.5:337.5
$112.5 would be the earnings of hotdogs
$337.5 would be the earnings of the drinks
Now we divide each individually by its cost
$112.5/3.5
= 32 1/7,
$337.5/1.5
= 225
We will round the hotdogs to 33 as the word problem says "sold enough to make."

Lewis is building a train layout and wants to build a model of the train station in his city. He wants it to be exactly to scale to match his engine. The engine measures 8 inches long and is the model of a train that is 80 feet long. If the station in his city is 30 feet by 60 feet by 40 feet, what are the dimensions of his model of the train station? Please answer
The dimensions of his model of the train station would be
3 inches by 6 inches by 4 inches.
What is scale factor?Scale factor is a dimensionless constant value that is used to compare the size of two objects. It is denoted by [K]. Mathematically -
K = O[1]/O[2]
Given is Lewis who is building a train layout and wants to build a model of the train station in his city. He wants it to be exactly to scale to match his engine. The engine measures 8 inches long and is the model of a train that is 80 feet long. The station in his city is 30 feet by 60 feet by 40 feet.
Now, it is given here that Lewis assumed a dilation model in which 80 feet is 8 inches long. Then -
80 feet = 8 inches
So one feet will be -
1 ft = 8/80 = 1/10 inches
Now, the dimensions of station in Lewis native city is 30 feet by 60 feet by 40 feet.
Now, dilating the dimensions with a scale factor of 1/10 inches, we get -
30 feet = 30 x 1 feet = 30 x 1/10 = 3 inches
60 feet = 60 x 1 feet = 60 x 1/10 = 6 inches
40 feet = 40 x 1 feet = 40 x 1/10 = 4 inches
Therefore, the dimensions of his model of the train station would be
3 inches by 6 inches by 4 inches.

Sami made $23,400 last year in income from his job. He worked 30 hours per week and worked all 52 weeks of the year. What was his hourly pay rate? Sami made $ v per hour and $v per week.
$450
Step-by-step explanation:
The total income that Sam made last year is $23,400.
Since he worked 30 hours per week and worked all 52 weeks of the year, it means that the total number of hours that he worked for the year would be
52×30 = 1560 hours.
To determine how much Sam made per hour, we would divide the total amount made for the year by the number of hours worked. It becomes
Hourly rate = 23400/1560 = $15
Since Sam earns $15 per hour and he works 30 hours in a week, it means that his weekly rate would be
15×30 = $450
Answer:
15 per hour
450 a week
Step-by-step explanation:
52*30=1560 hours(total)
23400/1560=15

Step-by-step explanation:
find the equations of the tangents to the curve x = 6t2 2, y = 4t3 2 that pass through the point (8, 6). y = (smaller slope) y = (larger slope)
The equations of the tangents to the curve are y = 3x - 6 and y = -3x + 30.
To find the equations of the tangents to the curve, we need to determine the slope of the tangent line at the given point of tangency.
The given curve is defined by the parametric equations x = 6t^2 - 2 and y = 4t^3 - 2.
We can eliminate the parameter t by expressing t in terms of x.
Rearranging the first equation, we have t^2 = (x + 2) / 6, and taking the square root of both sides, we get t = ±√((x + 2) / 6).
Substituting this value of t into the equation for y, we have y = 4(±√((x + 2) / 6))^3 - 2.
Simplifying this expression, we obtain y = ±(4/3)√((x + 2)^3 / 6) - 2.
Now, let's find the slopes of the tangents at the point (8, 6). We take the derivative of y with respect to x and evaluate it at x = 8.
Differentiating y with respect to x, we get dy/dx = ±(4/3)√(2(x + 2)^3 / 3)(1 / 2) = ±(2/3)√((x + 2)^3 / 3).
Evaluating the derivative at x = 8, we have dy/dx = ±(2/3)√((8 + 2)^3 / 3) = ±(2/3)√(10^3 / 3) = ±(2/3)√(1000/3) = ±20√10/3.
Since the slopes of the tangents are given by the derivative, the two possible slopes are ±20√10/3.
Now we can find the equations of the tangents using the point-slope form. Using the point (8, 6), we have:
y - 6 = (±20√10/3)(x - 8).
Simplifying these equations, we get:
y = 3x - 6 and y = -3x + 30.
Therefore, the equations of the tangents to the curve that pass through the point (8, 6) are y = 3x - 6 (the smaller slope) and y = -3x + 30 (the larger slope).
