Answer:84
Step-by-step explanation:
Identify the data level (nominal, ordinal, interval, or ratio) that best describes each of the following cases: a.The title of a randomly selected individual's favorite book Nominal b.The height of a randomly selected semi tractor and trailer on I-70 Ratio c.Placement (1st, 2nd, etc.) within a video game tournament Ordinal d.The temperature in Paris, France at noon Interval
Answer:
a. The title of a randomly selected individual's favorite book --> Nominal
b. The height of a randomly selected semi tractor and trailer on I 70 --> Ratio
c. Placement (1st, 2nd, etc.) within a video game tournament --> Ordinal
d. The temperature in Paris, France at noon --> Interval
Step-by-step explanation:
Required
The level of measurement of each
The question was submitted along with the (correct) answers; So, I will provide the explanations
(a) When data are measured using tags and labels; the level of measurement is Nominal
In (a), the data are measured using titles; this represents nominal level
(b) When data are measured using differences or intervals; the level of measurement is Ratio.
In (b), the data are represented using ratio such as 1 - 70 (i.e. 1 to 70); this represents ratio level
(c) When data are measured using orders such as first, second, etc.; the level of measurement is Ordinal
In (c), the data are categorized using 1st, 2nd, etc...; this represents ordinal level
(d) When data are measured using interpretable and meaningful intervals; the level of measurement is Interval;
In (d), the data are categorized using temperature at a certain interval; this represents interval level

If x=2at/(1+t²)
, Y=b(1-t²)/(1+t²)
Answer:
x=2at/(1+t²)
dx/dt =[(1+t²)(2at)'-(2at)(1+t²)']/(1+t²)²
dx/dt=[(1+t²)(2a)-(2at)(2t)]/(1+t²)²
dx/dt=[2a+2at²-4at²]/(1+t²)²
dx/dt=[2a-2at²]/(1+t²)²
y=[b(1-t²)]/(1+t²)
dy/dt=[(1+t²)(b(1-t²))'-b(1-t²)(1+t²)']/(1+t²)²
dy/dt=[((1+t²)(-2bt)-b(1-t²)(2t)]/(1+t²)²
dy/dt=(-2bt-2bt³-2bt+2bt³)/(1+t²)²
dy/dt=(-4bt)/(1+t²)²
dy/dx=(dy/dt)/(dx/dt)
dy/dx=[(-4bt)/(1+t²)²]/[(2a-2at²)/(1+t²)²]
Cancelling common denominator
dy/dx=(-4bt)/(2a-2at²)
dy/dx=(-2bt)/(a-at²)
dy/dx=(2bt)/(at²-a)
Differentiating the above equation
y''=d²y/dx²=D[(2bt)/(at²-a)]
y''=[(at²-a)D(2bt)-(2bt)D(at²-a)]/(at²-a)²
y''=[(at²-a)(2b)(dt/dx)-(2bt)(2at)(dt/dx)]/(at²-a)²
dt/dx=(1+t²)²/(2a-2at²)
y''=[(at²-a)(2b)[(1+t²)²/(2a(1-t²))]-
(4abt²)[(1+t²)²/(2a-2at²)]/(at²-a)²
y''=[(-b)(1+t²)²-(2bt²)[(1+t²)²/(1-t²)]/(at²-a)²
y''=[(-b)(1+t²)²(1-t²)-(2bt²)(1+t²)²]/[(1-t²)(at²-a)²]
y''=[b(1+t²)²(t²-1)-2bt²(1+t²)²]/[(1-t²)(at²-a)²]

Explanation:
f(x) is the outer function, so the final output -8 corresponds to f(x)
We see that f(-4) = -8 in the first column of the table. I'm starting with the output and working my way backward to get the input. So we started with -8 and worked back to -4.
Then we move to the g(x) function to follow the same pattern: start with the output and move to the input. We start at -4 in the g(x) bubble and move to 3 in the x bubble.
In short, g(3) = -4
So,
f(g(x)) = f(g(3)) = f(-4) = -8
We see that x = 3 leads to f(g(x)) = -8

In the accompanying diagram, triangle ABC is similar to triangle RST, BC= 12, AC=15, and ST= 8. Find RT.
Answer:
10
Step-by-step explanation:
ABC is similar to RST,
so BC is corresponding to ST, and AC is corresponding to RT
BC=12 and ST=8
so the scale factor from RST to ABC is 1.5 and the scale factor from ABC to RST is 2/3 because 12*(2/3) is 8, and 8*1.5 is 12.
now apply this to AC to find RT
AC=15
15*(2/3)=10
10*1.5=15
RT =10
Suppose we want to write 2/3 as an equivalent fraction with a denominator of 15. What number must we multiply both the numerator and the denominator by?
Answer:
5

a city council consists of 7 democrats and 7 republicans. if a committee of 4 people is selected, find the probability of selecting 2 democrats and 2 republicans
Answer:
The probability of selecting 2 Democrats and 2 Republicans is 29.36%.
Step-by-step explanation:
Given that a city council consists of 7 democrats and 7 republicans, to determine, if a committee of 4 people is selected, the probability of selecting 2 Democrats and 2 Republicans must be performed the following calculation:
7/14 x 6/13 x 7/12 x 6/11 = X
0.5 x 0.46 x 0.58 x 0.54 = X
0.0734 = X
0.0734 x 100 = 7.34 x 4 = 29.36
Therefore, the probability of selecting 2 Democrats and 2 Republicans is 29.36%.

A used book store also started selling used CDs and videos. In the first week, the store sold a combination of 40 CDs and videos. They charged $4 per CD and $6 per video and the total sales were $184. Determine the total number of CDs and videos sold.
Answer:
28 CD and 12 Video
Step-by-step explanation:
6 (x) + 4 (y) = 184
6 (28) + 4 (12) =184
168 + 48 = 184

Find the gradient of the line segment between the points (-2,7) and (4,3). Give your answer in its simplest form
Answer:
m = - 2/3 or
m = - 0.66667.
I don't know which form is simpler.
Step-by-step explanation:
All you want is the slope.
The slope formula is
m = (y2 - y1) / (x2 - x1)
y2 = 7
y1 = 3
x2 = - 2
x1 = 4
My choice of which one is 1 and which one is 2 is totally arbitrary. You could have made y2 = 3 and y1 = 7 and x2 = 4 and x1 = -2
m = (7 - 3) / (-2 - 4)
m = 4 / - 6
m = -2/3 or
m = - 0.6667
Alexis bought 6 pounds of hamburger meat for a
barbecue. How many ounces of meat did she buy?
Answer:
96
Step-by-step explanation:
1 pound=16 ounces
6x16=96
Answer:
She bought 96 ounces.
Step-by-step explanation:
When you convert 6 pounds into ounces it's 96 ounces.
1 pound equals 16 ounces.
16 ounces times 6 is 96.
Let X = the number of nonzero digits in a randomly selected 5-digit PIN that has no restriction on the digits. What are the possible values of X? Give three possible outcomes and their associated X values
Answer: there are total 100,000 5-digit PINs.
Three Possible outcomes Associated X values
12345 5
04555 4
00001 1
Step-by-step explanation:
Here, X = the number of nonzero digits in a randomly selected 5-digit PIN that has no restriction on the digits.
Possible number of outcomes = 10 x 10 x 10 x 10 x 10
= 100,000
Possible outcomes Associated X values
12345 5
04555 4
00001 1
Hence, there are total 100,000 5-digit PINs.
Three Possible outcomes Associated X values
12345 5
04555 4

An experiment using 35 guinea pigs is set up to study the weight of the pigs after injecting them with a drug. If the population mean is 23.5 grams with a standard deviation of 3.4 grams, what is the margin of error of the sample mean?
I ONLY NEED ONE ANSWER, AND HAS TO BE THE CORRECT ONE!
A. 0.097 grams
B. 0.575 grams
C. 0.701 grams
D. 1.149 grams
E. 1.403 grams
Answer:
Step-by-step explanation:
The margin of error for the sample is roughly 0.255 gm.
What is Standard Deviation?A set of values' variance or dispersion is measured by the standard deviation.
What is a confidence interval?A confidence interval is made up of the mean of your estimate plus and minus the estimate's range.
This is the range of values you expect your estimate to fall within if you repeat the test, within a given level of confidence. Confidence is another name for probability in statistics.
Given,
Standard deviation = 3.4 gm
Population mean = 23.5 gm
Number of pigs = 35
We know, Margin of Error = [tex]\frac{\sqrt{\mu\times\sqrt{\sigma}}}{n}[/tex]
ME = [tex]\frac{\sqrt{23.5\times\sqrt{3.4}}}{35}[/tex].
ME = 0.225 gm.
As a result, the sample mean's margin of error is roughly 0.255 gm.
