It is assumed that approximately 15% of adults in the U.S. are left-handed. Consider the probability that among 100 adults selected in the U.S., there are at least 30 who are left-handed. Given that the adults surveyed were selected without replacement, can the probability be found by using the binomial probability formula with x counting the number who are left-handed? Who or why not?
No, we cannot use the binomial probability formula with x counting the number who are left-handed in this case
This is because the adults surveyed were selected without replacement. The binomial distribution requires that the samples are independent and identically distributed (i.e., the probability of success remains constant for each trial).
However, when we sample without replacement, the probabilities are not constant because the population size changes with each selection. This means that the probability of selecting a left-handed person for the first selection is not the same as the probability of selecting a left-handed person for the second selection, and so on. Therefore, we cannot use the binomial distribution to calculate the probability of at least 30 left-handed adults among 100 selected without replacement from the US population.
Instead, we can use the hypergeometric distribution to calculate the probability of at least 30 left-handed adults among 100 selected without replacement from the US population. The hypergeometric distribution takes into account the changing probabilities as each selection is made without assuming that the selections are independent.

The correlation analysis indicates a moderate positive relationship between Column X and Column Y.
To perform correlation analysis, we can use the Pearson correlation coefficient (r) to measure the linear relationship between two variables, in this case, Column X and Column Y. The value of r ranges from -1 to 1, where 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no correlation.
Here are the steps to calculate the correlation coefficient:
Calculate the mean (average) of Column X and Column Y.
Mean(X) = (10+6+39+24+35+12+33+32+23+10+16+16+35+28+5+22+12+44+15+40+46+35+28+9+9+8+35+15+34+16+19+17+21) / 32 = 24.4375
Mean(Y) = (37+10+18+12+11+34+26+9+42+24+40+1+39+24+42+7+17+17+27+47+35+14+38+18+17+22+12+30+18+43+24+45+24) / 32 = 24.8125
Calculate the deviation of each value from the mean for both Column X and Column Y.
Deviation(X) = (10-24.4375, 6-24.4375, 39-24.4375, 24-24.4375, ...)
Deviation(Y) = (37-24.8125, 10-24.8125, 18-24.8125, 12-24.8125, ...)
Calculate the product of the deviations for each pair of values.
Product(X, Y) = (Deviation(X1) * Deviation(Y1), Deviation(X2) * Deviation(Y2), ...)
Calculate the sum of the product of deviations.
Sum(Product(X, Y)) = (Product(X1, Y1) + Product(X2, Y2) + ...)
Calculate the standard deviation of Column X and Column Y.
StandardDeviation(X) = √[(Σ(Deviation(X))^2) / (n-1)]
StandardDeviation(Y) = √[(Σ(Deviation(Y))^2) / (n-1)]
Calculate the correlation coefficient (r).
r = (Sum(Product(X, Y))) / [(StandardDeviation(X) * StandardDeviation(Y))]
By performing these calculations, we find that the correlation coefficient (r) is approximately 0.413. Since the value is positive and between 0 and 1, we can conclude that there is a moderate positive relationship between Column X and Column Y.

1.2 divided by 8 = 3 divided by (5x + 7)
Answer:
Decimal--x= -1.39
Fraction--x= -139/100
Step-by-step explanation:
You want to get x by itself in this problem
You have to distribute the 3 into the parenthesis first
1.2/8=15x+21
Now you can do 2 of either things....you can either divide 1.2/8 and then subtract 21 from both sides or you can just subtract 21 from both sides without dividing. I will use option 2.
1.2/8-21=15x+21-21
So now you cancel out the 21 on the right side and get...
-20.85=15x
Now divide by 15
-1.39=x in fraction form -139/100=x

Melissa and Jane are planting trees. Melissa plants 10 trees in 1 hour. Jane plants 17 tree in 2 hours.
Enter an equation that can be used to find the number of hours t, takes Melissa and jane to plant 111 trees together
Answer:
6 hours
Step-by-step explanation:
Let both of them plan for t hours to plant 111 trees n t hours
Melissa can plants 10 trees in 1 hour
in t hours she can plant 10 t trees
Jane plants 17 tree in 2 hours
in one hour Jane can plant 17/2 trees
in t hours she can plant (17/2)t trees.
Total trees planted by both of them in t hours in terms of t will be
10t + (17/2)t
= (10t*2 + 17t)/2
= (20t + 17t)/2
= 37t/2
but it is given that they planted 111 trees together
so 37t/2 should be equal to 111
37t/2 = 111
=> 37t = 111*2 = 222
=> t = 222/37 = 6.
Thus, it takes 6 hours for both of them to plant 111 trees together.

Answer:
C. 2.
Step-by-step explanation:
The graph descends from the left so the coefficient of the leading term is negative. It is also a cubic equation with zeros of -20, about 6.5 and about 13. so we can write the equation as below. The last 2 values can only be guessed because the x axis only shows values which are multiples of 5.
f(x) = a(x + 20)(x - 6.5)(x - 13) where a is a negative constant.
(This is only an approximation).
By the Remainder theorem, when the expression is divided by (x + 10):
f(-10) = -20 so we have
-20 = a (-10 + 20)(-10-6.5)(-10 - 13)
(10)(-16.5)(-23)a = -20
a = -20 / (10)(-16.5)(-23)
a = -0.0053
When the equation is divided by (x - 10) then f(10) is the remainder so substituting we have as the remainder:
-0.0053(10+20)(10-6.5)(10 -13)
-0.0053 * 30 * 3.5 * -3
= 1.7 approximately.
Looks like the answer is 2.
the type of nonprobability design that is most likely to yield a representative sample is:
The type of nonprobability design that is most likely to yield a representative sample is a stratified random sampling.
In stratified random sampling, the population is divided into distinct subgroups or strata based on certain characteristics or variables that are relevant to the research objective. Then, a random sample is selected from each stratum proportionally to the size or importance of that stratum in the population. This approach ensures that the sample reflects the diversity and heterogeneity of the population.
By stratifying the population and using random sampling within each stratum, the stratified random sampling design increases the likelihood of obtaining a representative sample. It allows for accurate representation of different groups within the population, which can help reduce sampling bias and provide more precise estimates of population characteristics.
However, it's important to note that even with stratified random sampling, there may still be limitations and potential sources of bias. Factors such as nonresponse rates and the accuracy of the population data used for stratification can impact the representativeness of the sample. Nevertheless, when properly implemented, stratified random sampling is a valuable nonprobability design for achieving representativeness in a sample.

The tires on Eric's car have a diameter of 18 inches. Rounded to the nearest whole number, how many rotations per second does each tire
make when Eric is driving at a rate of 88 feet per second?
A.) 2
B.) 19
C.) 37
D.) 59
Answer:
Step-by-step explanation:
We need to figure out how far Eric's car takes him in 1 rotation based on the diameter of his tire in feet. If the diameter of the tire is 18", then it is 1.5'. The circumference will tell us the distance 1 rotation of his tires will take him:
C = 3.1415(1.5) so
C = 4.71225 feet is how far he goes in 1 rotation. If he travels 88 feet in 1 second, we can figure the number of rotations by dividing 88 by 4.71225 to give us the unit rate (or, rotations per second his car makes). This quotient is 18.67 feet per sec, which rounds to 19, choice B.
Fill in the blank with an appropriate word, phrase, or symbol(s). The number of regions created when constructing a Venn diagram with three overlapping sets is The number of regions created when constructing a Venn diagram with three overlapping sets is 8 3 6
The number of regions created when constructing a Venn diagram with three overlapping sets is 8.
In a Venn diagram, each set is represented by a circle, and the overlapping regions represent the elements that belong to multiple sets.
When three sets overlap, there are different combinations of elements that can be present in each region.
For three sets, the number of regions can be calculated using the formula:
Number of Regions = 2^(Number of Sets)
In this case, since we have three sets, the formula becomes:
Number of Regions = 2^3 = 8
So, when constructing a Venn diagram with three overlapping sets, there will be a total of 8 regions formed.
Each region represents a unique combination of elements belonging to different sets.
These regions help visualize the relationships and intersections between the sets, providing a graphical representation of set theory concepts and aiding in analyzing data that falls into multiple categories.
Therefore, the correct answer is 8.

Calculate the density of benzene if 0.10L has a mass of 36.4g.
Answer:
\(d=0.364\ g/cm^3\)
Step-by-step explanation:
It is given that,
Mass of benzene, m = 0.1 L
Mass, m = 36.4 g
We know that, 1 L = 1000 cm³
0.1 L = 100 cm³
The density of an object is equal to its mass divided by its volume. So,
\(\rho=\dfrac{m}{V}\\\\=\dfrac{36.4\ g}{100\ cm^3}\\\\=0.364\ g/cm^3\)
So, the density of benzene is \(0.364\ g/cm^3\).

Answer:
13.0 miles
Step-by-step explanation:
We can use the Pythagorean Theorem to figure out the straight line distance from your starting point to your ending point.
To construct a triangle which we can apply the Pythagorean Theorem to, we have to add up the total miles in each direction.
On the east-west axis, the total distance traveled is 5 miles.
On the north-south axis, the total distance traveled is 12 miles.
We can make these two values the legs (short sides) of a right triangle, which we can then plug into the Pythagorean Theorem:
a² + b² = c²
5² + 12² = c²
25 + 144 = c²
169 = c²
√(169) = √(c²)
c = 13
So, the straight line distance from your starting point is 13.0 miles.

Answer:
AC=16 inches
Step-by-step explanation:
Given two side lengths of a triangle as x and y (x greater than y), the third side z must satisfy the inequality:
x - y ≤ z ≤ x + y
The side lengths are x=17 and y=10, thus:

The equation of the plane that passes through points (1, 1, 1), (2, 0, 3), and (-1, 4, 2) can be found using the point-normal form of the equation of a plane.
To find the normal vector of the plane, we can take the cross product of two vectors formed by the given points. Let's call the vectors formed by (1, 1, 1) and (2, 0, 3) as vector A, and the vectors formed by (1, 1, 1) and (-1, 4, 2) as vector B.
Vector A = (2-1, 0-1, 3-1) = (1, -1, 2)
Vector B = (-1-1, 4-1, 2-1) = (-2, 3, 1)
Now, taking the cross product of A and B, we get the normal vector of the plane:
Normal vector = A x B = (1, -1, 2) x (-2, 3, 1) = (-1, -5, -5)
Using the normal vector and one of the given points (let's use (1, 1, 1)), we can write the equation of the plane as:
-1(x - 1) - 5(y - 1) - 5(z - 1) = 0
Simplifying the equation, we get:
-x - 5y - 5z + 11 = 0

For a 30-year house mortgage of $400,000 at 5.8% interest, find the following. (round your final answers to two decimal places.) (a) the amount of the first monthly payment that goes to repay principal (b) the amount of the 121st month's payment (after 10 years) that goes toward payment of principal
a) The amount of the first monthly payment that goes to repay the principal is approximately $421.26. b) The amount of the 121st month's payment that goes toward payment of principal is approximately $55,833.31.
To find the amount of the first monthly payment that goes towards repaying the principal, we can use the amortization formula. The formula to calculate the monthly payment amount is:
P = (r * A) / (1 - (1 + r)⁻ⁿ)
Where:
P is the monthly payment amount,
r is the monthly interest rate,
A is the loan amount, and
n is the total number of monthly payments.
Let's calculate the monthly payment amount first:
Loan amount (A) = $400,000
Annual interest rate = 5.8%
Number of years (n) = 30
To convert the annual interest rate to a monthly interest rate, we divide it by 12 and convert it to a decimal:
Monthly interest rate (r) = (5.8% / 12) / 100 = 0.0048333
Number of monthly payments (n) = 30 years * 12 months/year = 360
Using the formula, we can calculate the monthly payment (P):
P = (0.0048333 * $400,000) / (1 - (1 + 0.0048333)⁻³⁶⁰)
P ≈ $2,354.59 (rounded to two decimal places)
(a) The amount of the first monthly payment that goes to repay the principal is equal to the monthly payment minus the interest accrued. Let's calculate it:
Interest for the first month = Loan amount * Monthly interest rate
Interest for the first month = $400,000 * 0.0048333 ≈ $1,933.33 (rounded to two decimal places)
Principal payment for the first month = Monthly payment - Interest for the first month
Principal payment for the first month = $2,354.59 - $1,933.33 ≈ $421.26 (rounded to two decimal places)
Therefore, the amount of the first monthly payment that goes to repay the principal is approximately $421.26.
(b) To find the amount of the 121st month's payment that goes toward payment of principal, we need to calculate the remaining loan balance after 10 years (120 months) and then subtract it from the initial loan amount.
Remaining loan balance after 10 years can be calculated using the amortization formula:
Remaining balance = P * ((1 - (1 + r)⁻ⁿ) / r) - P * (((1 + r)⁻ⁿ) - 1)
P = Monthly payment amount calculated earlier
r = Monthly interest rate calculated earlier
n = 360 (total number of monthly payments)
Remaining balance after 10 years = $2,354.59 * ((1 - (1 + 0.0048333)⁻¹²⁰) / 0.0048333) - $2,354.59 * (((1 + 0.0048333)⁻¹²⁰) - 1)
Remaining balance after 10 years ≈ $344,166.69 (rounded to two decimal places)
Amount of the 121st month's payment that goes toward payment of principal = Initial loan amount - Remaining balance after 10 years
Amount of the 121st month's payment that goes toward payment of principal = $400,000 - $344,166.69 ≈ $55,833.31 (rounded to two decimal places)
Therefore, the amount of the 121st month's payment that goes toward payment of principal is approximately $55,833.31.
