Answer: The answer is 6.3
Consider the population of the city of Beaumont. Over the course of a year, 800 people move into town. Of those that moved in, 180 have dark hair, 260 have red hair, and the remaining 360 are blonde. During this year a total of 1070 people move out, 470 with dark hair, 270 redheads, and 330 blondes. There are 223 newborns, 47 with dark hair, 90 with red hair, and 86 blondes. Finally, there are 168 deaths, 31 with dark hair, 66 with red hair, and 71 with blond hair. (Assume no one goes bald or changes their hair color.) What is the accumulation of red-haired people in Beaumont, for this year
Answer:
There were 14 red-haired people accumulated in Beaumont, for this year.
Step-by-step explanation:
The number of people who moved into town is = 800Number of dark haired people = 180
Number of red haired people = 260
Number of blonde haired people = 360
The number of people who moved out of town is = 1070Number of dark haired people = 470
Number of red haired people = 270
Number of blonde haired people = 330
The number of newborns in town is = 800Number of dark haired = 47
Number of red haired = 90
Number of blonde haired = 86
The number of deaths in town is = 168Number of dark haired people = 31
Number of red haired people = 66
Number of blonde haired people = 71
Compute the accumulation of red-haired people in Beaumont, for this year as follows:
Red hair = #Moved in - #Moved out + #Newborn - #Deaths
= 260 - 270 + 90 - 66
= 14
Thus, there were 14 red-haired people accumulated in Beaumont, for this year.
X+Y=4.25
16.90X+4Y=36.35
What are the values of X and Y
Answer:
Y = 2.75X = 1.5Step-by-step explanation:
X+Y=4.25
16.90X+4Y=36.35
That means that;
X = 4.25 - Y
Substituting X into the second equation is;
16.90 * (4.25 - Y) + 4Y = 36.35
71.825 - 16.90Y + 4Y = 36.35
71.825 - 12.90Y = 36.35
71.825 - 36.35 = 12.90Y
Y = 35.475/12.90
Y = 2.75
X = 4.25 - Y
= 4.25 - 2.75
= 1.5
From the computation done, the value of X is 2.75 and Y is 1.5.
The following information can be depicted:
X + Y=4.25 .... i
16.90X + 4Y=36.35 ..... ii
From equation i
X = 4.25 - Y
We'll substitute X into the second equation and this will be:
16.90(4.25 - Y) + 4Y = 36.35
71.825 - 16.90Y + 4Y = 36.35
71.825 - 12.90Y = 36.35
Collect life terms
71.825 - 36.35 = 12.90Y
Y = 35.475/12.90
Y = 2.75
Since X = 4.25 - Y
X = 4.25 - 2.75
X = 1.5

A rectangle that is 2 inches by 3 inches has been scaled by a factor of 7.
1. What are the side lengths of the scaled copy?
2. Suppose you want to scale the copy back to it's original size. What scale factor should you use?
Answer:
To get the new scaled copy length and width just multiply by seven (2x7 & 3x7)
New length would be 14 because it's "seven times" the original size
New width would be 21
Step-by-step explanation:
1.) 14 and 21
2.) 14 divided by 7 will give you 2
and 21 divided by 7 will give you 3
The answer for question 2 would be to divide your new answers (21 and 14) by the scaled factor of 7.
Gamal spent $12.50 at the book store. The difference between the amount he spent at the video game store and the amount he spent at the book store was $17. The equation d minus 12.50 = 17 can be used to represent this situation, where d is the amount Gamal spent at the video game store. Which equation is an equivalent equation that can be used to find the amount Gamal spent at the video game store?

The IQ of 10 adults is measured, and the results are 83, 87, 90, 92, 93, 100, 104, 111, 115, 121. Find the range of the data set. (4 points)
A: 83−121
B: 38
C: 96.5
D: 204
Answer:
B
Step-by-step explanation:
range = biggest - smallest
121 - 83 = 38
range = 38
the correct answer is B: 38, representing the difference between the highest and lowest values in the data set, and it correctly reflects the range of the given IQ scores.
To find the range of the data set, we need to determine the difference between the highest and lowest values in the set. Given the IQ scores of the 10 adults as 83, 87, 90, 92, 93, 100, 104, 111, 115, and 121, the highest value is 121, and the lowest value is 83.
Thus, the range can be calculated as 121 - 83, which equals 38. Therefore, the correct answer is B: 38, representing the difference between the highest and lowest values in the data set, and it correctly reflects the range of the given IQ scores.

Assume a recent sociological report states that university students drink 4.10 alcoholic drinks per week on average, with a standard deviation of 1.9101. Suppose Jason, a policy manager at a local university, decides to take a random sample of 125 university students to survey them about their drinking habits. Determine the mean and standard deviation of the sampling distribution of the sample mean alcohol consumption. Provide your answer with precision to two decimal places.
Answer:
4.10
0.17
Step-by-step explanation:
From the question, we know that
A recent sociological report stated that university students drink 4.10 alcoholic drinks per week on average, with a standard deviation of 1.9101.
Also, we're tasked with finding the mean and standard deviation of the sampling distribution of the sample mean alcohol consumption.
To find the mean of the sampling distribution, we take the sample mean of the same of that university students as a direct substitute. This then means that the mean of the sampling distribution of the sample mean alcohol consumption is 4.10 alcoholic drinks per week on average.
On the other hand, the standard deviation of the sampling distribution of the sample mean alcohol consumption is taken to be the division of the standard deviation of the sample mean. Mathematically, we have
Standard Deviation, S = 1.9101 / √125
Standard Deviation, S = 1.9101 / 11.18
Standard Deviation, S = 0.17
Therefore, the Standard Deviation is 0.17

The values are
[tex]\mu_{\= x } = \mu = 4.10[/tex]
And
[tex]\sigma _{\= x} = 0.38202[/tex]
Step-by-step explanation:
The population mean is [tex]\mu = 4.10[/tex]
The standard deviation is [tex]\sigma = 1.9101[/tex]
The sample size is n = 125 students
Generally the mean of the sampling distribution of the sample mean is equivalent to the population mean
i.e [tex]\mu_{\= x } = \mu = 4.10[/tex]
Generally the standard deviation of the sampling distribution of the sample mean alcohol consumption is mathematically represented as
[tex]\sigma _{\= x} = \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]\sigma _{\= x} = \frac{1.9101 }{\sqrt{125} }[/tex]
=> [tex]\sigma _{\= x} = 0.38202[/tex]

b)0.502
c)0.2114

Probability of being not left handed = 1-0.13 =0.87
They select a sample of five customers at random in their stores
a. The first lefty is the fifth person chosen
Probability that first lefty is the fifth person chosen =[tex]0.87 \times 0.87 \times 0.87 \times 0.87 \times 0.13=0.074[/tex]
b)There are some lefties among the 5 people=[tex]1-P(x=0)=1-0.87^5=0.502[/tex]
c)The first lefty is the second or third person=[tex]0.87 \times 0.13 + 0.87 \times 0.87 \times 0.13 =0.2114[/tex]

In kidney transplantations, compatibility between donor and receiver depends on such factors as blood type and antigens. Suppose that for a randomly selected donor from a large national kidney registry, there is a 10% chance that he or she is compatible with a specific receiver. A sample of size 5 donors are randomly selected from this registry. Find the probability that exactly 2 of the selected donors is compatible.
Answer:
The probability is [tex]P(X = 2)= 0.0729[/tex]
Step-by-step explanation:
From the question we are told that
The percentage that the donor is compactible is p = 0.10
The sample size is n = 5
Generally the probability that the donor is not compactible is
[tex]q = 1- p[/tex]
=> [tex]q = 1- 0.10 [/tex]
=> [tex]q = 0.90 [/tex]
Generally the probability that the exactly 2 of the selected donors is compatible mathematically represented as
[tex]P(X = 2)= \ ^{5}C_2 * p^2 * q^{5-2}[/tex]
Here C standards for combination
=> [tex]P(X = 2)= \ 10 * 0.10^2 * 0.90 ^{5-2}[/tex]
=> [tex]P(X = 2)= 0.0729[/tex]

Step-by-step explanation:
Well, you would just divide the "other" category and the "total" category and then move the decimal over 2 spaces, because you need to multiply by 100 to turn your answer into a percent, so:
Then once you multiply by 100, or move the decimal to the left 2 spaces, it becomes:
9.9%, which could be rounded to 10% or 9%.

The endpoints of AB are A(–7, –6) and B(5, 6). What are the coordinates of point C on AB that is 1/3 the distance from point A to point B?
Answer:
C
Step-by-step explanation:
find the distance between the two points and divide that by 3 first,
then you estimate the point that is from point A with that 1/3 distance
The coordinate of point C such that point C on AB that is 1/3 the distance from point A to point B is (-3,-2) so option (C) will be correct.
What are coordinates?A pair of numbers is used to express a point's position on a coordinate plane using the horizontal and vertical distinctions from the two reference axes. usually represented by pairs of x-values and y-values (x,y).
Coordinate a point with intercept m: n and bounded by coordinate (x₁, y₁) and (x₂, y₂) is given by
x = [m(x₂) + n(x₁)]/(m + n)
y = [m(y₂) + n(y₁)]/(m + n)
Here m = 1/3 and n = (1-1/3) = 2/3
And coordinates A(–7, –6) and B(5, 6).
So,
x = [ 1/3(5) + 2/3(-7) ]/ 1
x = -3
And,
y = [ 1/3(6) + 2/3(-6) ]/ 1
y = -2
So (-3,-2) will be the coordinate of point C.
Hence "The coordinate of point C is (-3,-2).

Answer:
Well, lets break this down.
If you try to add 26 + 26 it would be 52, which is above 48.
So, we have to find how many books he can read in one month.
All we have to do, is divide!
14 = dividend
26 = divisor
Step 1:
Start by setting it up with the divisor 26 on the left side and the dividend 14 on the right side like this:
