Which two options describe the standard deviation?
The variance square
The extreme distance from the mean expected from the data points
The square root of the variance.
The average distance from the mean expected of the data.
Answer:
The square root of the variance.
The average distance from the mean expected of the data.
Step-by-step explanation:
Standard deviation is a measure of dispersal. It determines the average distance from the mean expected of the data.
Variance is also related to the standard deviationIt is the square root of the variance. The dispersion or variation of a set of values away from the mean is the standard deviation.
Standard deviation = [tex]\sqrt{variance}[/tex]
Points H, G and F are collinear. Point G is between Hand G. Solve for x. HG = x, GF = 1, HF = 10 *
Answer:
x = 11
Step-by-step explanation:
It is given that,
Points H, G and F are collinear. Point G is between H and G.
It means,
HG = GH + HG
We have, HG = x, GH = 1, HG = 10
Putting all the values, we get:
x = 1 +10
x = 11
It is very clear that the value of x is 11.
Suppose a carpenter's ruler was marked in thirty-seconds. What would be the fraction and its decimal equivalent for the mark on the ruler between 29/32 and 30/32?
Answer:
the fraction and its decimal equivalent for the mark on the ruler
= 59/64 = 0.921875
Step-by-step explanation:
Given that;
A CARPENTER 's ruler is marked in thirty seconds
mark on the ruler between 29/32 and 30/32 is the average of the values
we know that average is the summation of all terms divided by the number of appearance of terms
so
= (29/32 + 30/32) / 2
= ((29 + 30) / 32) / 2
= (59 / 32) / 2
= 59 / 64
= 0.921875
therefore the fraction and its decimal equivalent for the mark on the ruler = 59/64 = 0.921875

There is a 30 percent chance that A can fix her busted computer. If A cannot, then there is a 40 percent chance that her friend B can fix it.
a) Find the probability it will be fixed by either A or B.
b) If it is fixed, what is the probability it will be fixed by B.
a) The probability that the computer will be fixed by either A or B is 58%.
b) The probability that it was fixed by B is 57.14%
Given data:
a)
To find the probability that the computer will be fixed by either A or B, we can use the principle of addition for probabilities.
The probability that A can fix the computer is 30% or 0.30, and the probability that B can fix the computer if A cannot is 40% or 0.40.
Therefore, the probability that either A or B can fix the computer is the sum of these probabilities:
P(A or B) = P(A) + P(B if A cannot) = 0.30 + (0.70 * 0.40) = 0.30 + 0.28 = 0.58
Therefore, there is a 58% probability that the computer will be fixed by either A or B.
b)
Let's denote event A as A fixing the computer and event B as B fixing the computer.
P(A) = 0.30 (probability A can fix the computer)
P(B|A') = 0.40 (probability B can fix the computer given that A cannot)
To find P(B|A), the probability that B fixes the computer given that it was fixed, use Bayes' theorem:
P(B|A) = (P(A|B) * P(B)) / P(A)
Since the computer is fixed, P(A) + P(A') = 1, so P(A) = 1 - P(A') = 1 - 0.30 = 0.70
P(B|A) = (P(A|B) * P(B)) / P(A)
P(B|A) = (1 * 0.40) / 0.70
P(B|A) = 0.40 / 0.70
P(B|A) ≈ 0.5714
Hence, if the computer is fixed, there is a 57.14% probability that it was fixed by B.

g Nationwide, a certain disease occurs only a small proportion of people (.000215). A certain town has 74,000 residents. Use the Poisson approximation. c) Determine the probability that the town has 30 or fewer residents with the illness.
Answer:
The probability that the town has 30 or fewer residents with the illness = 0.00052.
Step-by-step explanation:
So, we have the following set of data or information or parameters given from the question above and they are; the number of people living in that particular society/community/town = 74,000 residents and the proportion of people that the diseases affected = .000215.
The first step to do is to determine the expected number of people with disease. Thus, the expected number of people with disease = 74,000 × .000215 = 15.91.
Hence, the probability that the town has 30 or fewer residents with the illness = 1.23 × 10^-7 × 15.91^30/ 2.65253 × 10^-32 = 0.00052.
Note the formula used in the calculating the probability that the town has 30 or fewer residents with the illness = e^-λ × λ^x/ x!

Use 4's to create problems that will equal 1-12. Remember to use the correct order of operations to solve your problems: Parentheses, Exponents, Multiply or Divide, Add or Subtract.
Answer and Step-by-step explanation:
Solution:
Order of operations:
1- Parentheses
2- Exponent
3- Multiply
4- Divide
5- Subtract
By using these operations we can find out the solution of 4’s to create problems that will equal to 1 – 12.
1 = 44 / 44 or (4+4) / (4+4)
2= 4/4 + 4/4
3 = (4+4+4) /4
4 = 4 x (4 – 4) +4
5 = (4 x 4 + 4)/ 4
6 = 4 x .4 + 4.4
7 = 44 / 4 – 4
8 = 4 + 4.4 - .4
9 = 4/4 +4 +4
10 = 44 / 4.4
11= 4 / .4 + 4/4
12 = (44 + 4) / 4

In a laboratory, 3 technicians are analyzing the active ingredient in the product vials. Amir, Betty, and Carlos analyze 0.55, 0.30, and 0.15 of the vials, respectively. Inaccurate are 0.6 percent of the analyses conducted by Amir, 0.4 percent of the analyses conducted by Betty, and 1.0 percent of the analyses conducted by Carlos in this study. What is the probability that an inaccurate analysis, detected at final verification, was conducted by Carlos
Answer:
The probability is [tex]P(C | I) = 0.025[/tex]
Step-by-step explanation:
From the question we are told that
The proportion analyzed by Amir is P(A) = 0.55
The proportion analyzed by Betty is P(B) = 0.30
The proportion analyzed by Carlos is P(C) = 0.15
The inaccuracy by Amir is p = 0.6% = 0.006
The inaccuracy by Betty is b = 0.4% = 0.004
The inaccuracy by Carlos is c = 0.1% = 0.001
Generally the probability of inaccurate analysis is mathematically represented as
[tex]P(I) = P(A) * p + P(B) * b + P(C) * c[/tex]
=> [tex]P(I) = 0.55 * 0.006 + 0.30 * 0.004 + 0.15 * 0.001 [/tex]
=> [tex]P(I) = 0.006 [/tex]
Generally the probability that an inaccurate analysis, detected at final verification, was conducted by Carlos is mathematically represented as
[tex]P(C | I ) = \frac{P(C) * c}{P(I)}[/tex]
=> [tex]P(C | I) = \frac{ 0.15 * 0.001}{ 0.006}[/tex]

A nurse has an annual income of $52,175. The income tax the nurse must pay is 9%. What is the amount of income tax in dollars and cents that the nurse must pay?
Answer:
The amount of income tax in dollars and cents is $4,695.75
Step-by-step explanation:
To find the amount of income tax that should be paid, we simply use the percentage said to be for the income tax
Mathematically;
income tax = 9% of 52,175
= 9/100 * 52175
= $4695.75
The income tax to be paid on the income is $52,175
Answer:4695.75
Step-by-step explanation:
Well if u made 52175 a whole then put 9 as a percentage you would cross multiply 52175 with 9 then divided with the whole percentage (100)

Assume a Poisson random variable has a mean of 5 successes over a 125-minute period.
a. Find the mean of the random variable, defined by the time between successes
b. What is the rate parameter of the appropriate exponential distribution? (Round your answer to 2 decimal places.)
Rate parameter
c. Find the probability that the time to success will be more than 63 minutes. (Round intermediate calculations to at least 4 decimal places and final answer to 4 decimal places.)
Answer:
a
[tex]\mu = 25 [/tex]
b
[tex]\lambda =0.04 [/tex]
c
[tex]P(X > 65 ) =0.0742 [/tex]
Step-by-step explanation:
From the question we are told that
The number of success is n = 5
The time duration is N = 125 minutes
Generally the mean of the random variable is mathematically represented as
[tex]\mu = \frac{N}{n}[/tex]
=> [tex]\mu = \frac{125}{5}[/tex]
=> [tex]\mu = 25 [/tex]
Generally the rate parameter is mathematically represented as
[tex]\lambda = \frac{1}{\mu}[/tex]
=> [tex]\lambda = \frac{1}{25}[/tex]
=> [tex]\lambda =0.04 [/tex]
Generally the cumulative distribution function for exponential distribution function is
[tex]F(x) = \left \{0 \ \ \ \ \ \ x \le 0}} \atop {1 -e^{-\lambda t }\ x>0}} \right.[/tex]
Generally the probability that the time to success will be more than 63 minutes is mathematically represented as
[tex]P(X > 65 ) = 1 - P(X \le 65)[/tex]
Here
[tex]P(X \le 65) = 1 -e^{-65 * \lambda }[/tex]
=> [tex]P(X \le 65) = 1 -e^{-65 * 0.04 }[/tex]
=> [tex]P(X \le 65) = 0.92573[/tex]
So
[tex]P(X > 65 ) = 1 - 0.92573 [/tex]
[tex]P(X > 65 ) =0.0742 [/tex]

What are the similarities and differences between translations, reflections, and rotations? Describe a real-world transformation? Give examples of two different transformations.
Answer:
There are four main types of transformations: translation, rotation, reflection and dilation.Translation moves the object without rotating it or changing its size. Reflection flips the object about a line of reflection. Rotation rotates a figure about a fixed point. Dilation changes the size of a figure without changing its essential shape.When you reflect a point across the x-axis, the x-coordinate remains the same,but the y-coordinate is transformed into its opposite. a negative angle of rotation turns the figure in a clockwise direction.Transformation can be done in a number of ways, including reflection, rotation, and translation. ~When you reflect a point across the x-axis, the x-coordinate remains the same,but the y-coordinate is transformed into its opposite. a negative angle of rotation turns the figure in a clockwise direction.
Step-by-step explanation:
Transformation simply means changing the size and location of shapes, lines and points in the coordinate geometry
The similarities
Translations, reflections, and rotations are all rigid transformations
This means that, they do not change the side lengths and angle measure of the shape they transform.
The differences
Translation: can only change the position of shapes without rotating or flipping the shape.
Rotation: This means that a shape is to be turned around a center at a particular degree
Reflection: This simply means that, a shape is mirrored over a line
