False. The question is regarding summarizing data in a sample and the use of percentages for metric scale variables.
Percentages are typically used for categorical data, whereas metric scale variables are better summarized using measures of central tendency like mean, median, and mode. Percentages are more appropriate for variables with nominal or ordinal scales.
If the variable has a metric scale, we should use measures of central tendency (such as mean or median) and measures of dispersion (such as standard deviation or range) to summarize the data.
Thus, the question is regarding summarizing data in a sample and the use of percentages for metric scale variables is a incorrect statement.

suppose that family incomes in the town of hawkins, indiana are normally distributed with a mean income of $75,000 and a standard deviation of $30,000. if the poverty level is $25,000, what proportion of hawkins' population is living in poverty? round your answer to four decimal places (include a zero if necessary). what is the income of a family in hawkins in the 90th percentile? round your answer to two decimal places (include a zero if necessary and do not include a dollar ($) sign in your answer.
Approximately 4.75% of the population in Hawkins is living in poverty. and a family in Hawkins in the 90th percentile has an income of $109,400.
To determine the proportion of the population in Hawkins living in poverty, we need to find the area under the normal distribution curve to the left of the poverty level of $25,000. We can do this by standardizing the poverty level using the formula:
Z = (X - μ) / σ
Where X is the poverty level, μ is the mean income, and σ is the standard deviation. Plugging in the values, we get:
Z = (25,000 - 75,000) / 30,000 = -1.67
Using a standard normal distribution table or calculator, we can find that the proportion of the population to the left of Z = -1.67 is 0.0475.
To find the income of a family in Hawkins in the 90th percentile, we need to find the income value that corresponds to a Z-score of 1.28. Again, using the standardization formula, we get:
Z = (X - μ) / σ
1.28 = (X - 75,000) / 30,000
Solving for X, we get:
X = 109,400

ronnie and tanya both identically priced cans of chili and identically priced jars of salsa to make a dip. ronnie bought 3 cans of chili and 2 jars of salsa for $15.12. tanya bought 2 cans of chili and 4 jars of salsa for $19.36. write a system of equations that could be used to find, x, the cost of one can of chili, and y, the cost of one jar of salsa. responses
The system of linear equations that can be formed to find x and y is 3x + 2y = 15.12 and 2x + 4y = 19.36. Then one can of chili costs $2.37 and one jar of salsa costs $4.005.
Let us consider x being the cost of one can of chili and y be the cost of one jar of salsa.
Then we can write two equations
3x + 2y = 15.12
2x + 4y = 19.36
We can multiply the first linear equation by 2 and subtract it from the second linear equation in order to eliminate x
(2x + 4y = 19.36) - 2(3x + 2y = 15.12)
= -4x + 0y
= -9.48
Applying Simplification to this equation
-4x = -9.48
Dividing both sides by -4 gives us:
x = 2.37
Now we can place this value of x into either of the original equations to find y
3(2.37) + 2y = 15.12
7.11 + 2y = 15.12
Subtracting 7.11 from both sides
2y = 8.01
Dividing both sides by 2
y = 4.005
Then, one can of chili costs $2.37 and one jar of salsa costs $4.005.

in the past year there were 30 days on which accidents occurred along a certain stretch of highway 101. assume that the probability that an accident occurs on any one day is 30/365 and that each day is independent of the others. what is the probability that there will be no accidents during the first 2 weeks of january?
The probability that there will be no accidents during the first 2 weeks of January is calculated to be approximately 0.778 or 77.8%.
The first two weeks of January consist of 14 days, so we want to find the probability that no accidents occur in 14 days given that the probability of an accident occurring on any given day is 30/365. We can use the binomial distribution to solve this problem.
Let X be the number of accidents in 14 days. Then X follows a binomial distribution with n = 14 and p = 30/365. The probability of no accidents in 14 days is P(X = 0), which is given by the formula:
P(X = 0) = (n choose 0) x p⁰ x (1-p)⁽ⁿ⁻⁰⁾
where "n choose 0" is the number of ways to choose 0 accidents out of n days, which is simply 1.
Substituting n = 14 and p = 30/365, we get:
P(X = 0) = (1) x (30/365)⁰ x (1 - 30/365)⁽¹⁴⁻⁰⁾ ≈ 0.778
Therefore, the probability that there will be no accidents during the first 2 weeks of January is approximately 0.778 or 77.8%.

The chef of a pizza place used 9 packages of pepperoni and 3/8 of a package of sausage. How much more pepperoni than sausage did the chef use?
The Amount of pepperoni used = 9 packages, Amount of sausage used= was 0.9375 packages of pepperoni, so the chef used 8.0625 more packages of pepperoni than sausage.
What is multiplication?Multiplication is a basic arithmetic operation that involves combining or adding equal groups of numbers. It is represented by the symbol "x" or "*", and the result of multiplying two or more numbers is called the product. For example, 2 x 3 = 6, which means two groups of three (2 multiplied by 3) equals six.
According to the given information:The chef used 9 packages of pepperoni and 3/8 of a package of sausage. To compare the amount of pepperoni and sausage used, we need to express them in a common unit of measurement. We can do this by converting the 3/8 package of sausage to the equivalent amount in packages of pepperoni.
To do this, we can notice that 1 package of sausage is equivalent to 2.5 packages of pepperoni. Therefore, we can find the amount of sausage in packages of pepperoni as:
(3/8) package of sausage * 2.5 packages of pepperoni per 1 package of sausage = (3/8) * 2.5 packages of pepperoni = 0.9375 packages of pepperoni
Now, we can compare the amount of pepperoni and sausage used:
Amount of pepperoni used = 9 packages
Amount of sausage used = 0.9375 packages of pepperoni
To find the difference, we can subtract the amount of sausage used from the amount of pepperoni used:
9 packages of pepperoni - 0.9375 packages of pepperoni = 8.0625 packages of pepperoni
Therefore, the chef used 8.0625 more packages of pepperoni than sausage.
Therefore, the Amount of pepperoni used = 9 packages, Amount of sausage used= was 0.9375 packages of pepperoni, so the chef used 8.0625 more packages of pepperoni than sausage.

The cost is $10 for SUV's and $5 for cars. Twenty-five percent of the money raised goes to the football team, thirty percent goes to the soccer team and the remaining percentage goes toward the basketball team. Write an expression to represent how much the soccer team and football team will receive.''
Answer:
Let's start with calculating how much money is raised in total:
- Let's assume there are x SUVs and y cars.
- The cost for one SUV is $10 and the cost for one car is $5.
- Therefore, the total cost for all SUVs is 10x and the total cost for all cars is 5y.
- The total cost is the sum of these: 10x + 5y.
Now we need to calculate how much money each team will get. We know that:
- 25% of the money goes to the football team. This can be written as 0.25(10x + 5y) or 2.5x + 1.25y.
- 30% of the money goes to the soccer team. This can be written as 0.3(10x + 5y) or 3x + 1.5y.
- The remaining percent goes to the basketball team. This is 100% - 25% - 30%, which is 45%. This can be written as 0.45(10x + 5y) or 4.5x + 2.25y.
Therefore, the expression to represent how much the soccer team and football team will receive is:
2.5x + 1.25y + 3x + 1.5y = 5.5x + 2.75y

While taking part in a bicycle race, Michael only manages to cycle 4/5 of the way. His father manages to complete 9/11 of the race. Who rode the farthest
Step-by-step explanation:
so, the question is, what is bigger : 4/5 or 9/11.
to do this we need to bring both fractions to the same denominator (bottom part).
the least common multiple of 5 and 11 is simply 55.
4/5 = (4/5) × (11/11) = 44/55
9/11 = (9/11) × (5/5) = 45/55
as 45/55 > 44/55, we know now that 9/11 > 4/5, and that the father had therefore traveled the farthest.

Rectangles are quadrilaterals having four right angles in the Euclidean plane of geometry. Various definitions include an equiangular quadrilateral, A closed, four-sided rectangle is a two-dimensional shape. A rectangle's opposite sides are equal and parallel to one another, and all of its angles are exactly 90 degrees.
To determine the area of the stained glass window, we can first calculate the area of the rectangle by multiplying its length and width, which is 16 in × 9 in = 144 in².
Next, we need to find the area of each semicircle. The diameter of each semicircle is 4 in, so the radius is 2 in. The area of a circle is given by the formula πr², so the area of each semicircle is (π × (2 in)²) ÷ 2 = 6.28 in².
Since there are two semicircles, their total area is 6.28 in² × 2 = 12.56 in².
To get the total area of the stained glass window, we add the area of the rectangle and the area of the semicircles, giving us a total of 144 in² + 12.56 in² = 156.56 in².
Therefore, the area of the stained glass window is 156.56 in².

Angelia lives 2 1/3 miles from school. she rides her bicycle to school and back each day for 5 days. how many miles does she ride in 5 days
Answer: Angelia rides 23.33 miles in 5 days.
Step-by-step explanation:
Angelia lives 2 1/3 miles from school, which is equivalent to 2 + 1/3 = 2.333 miles. She rides her bicycle to school and back each day, so she travels twice the distance daily.
Daily distance = 2 × 2.333 miles = 4.666 miles
She does this for 5 days, so the total distance she rides in 5 days is:
Total distance = 4.666 miles/day × 5 days = 23.33 miles
So, Angelia rides 23.33 miles in 5 days.
Answer:23.5 miles (i think)
Step-by-step explanation:
If Angelia bikes 2 1/3 miles 2 times everyday that means she would ride about 4.7 miles per day. In 5 days she would ride 23.5 miles because 4.7 times 5 is 23.5

The double integral ∬D f(x, y) dxdy = -35²⁸/₃₀
How to find the double integral?Given the double integral ∬D f(x, y) dxdy where D: y = x, y = x², x = 3. and f(x, y) is (x - y)
First, we find the points of intersection.
So, y = x, y = x²
x = x²
x - x² = 0
x(1 - x) = 0
x = 0 or 1 - x = 0
x = 0 or x = 1
So, we integrate x on the interval [0,1] ∪ [1,3]

Answer:
A 4-quart carton of yogurt costs $7.04. The price per cup is $0.44 per cup.
Step-by-step explanation:
What is the price?
A price is the sum of money that one party pays or receives in exchange for another's goods or services. The cost of production may go by another name in some circumstances.
If a product is classified as a "good" in a commercial exchange, its price is most likely to be referred to as such.
4 quarts equal one gallon.
That makes 8 quarts ½ a gallon and 4 cups make one quart, as seen by the gallon man in the attachments.
4 quarts equal 16 cups, because 4 x 4 is 16.
$7.04 is the price for a four-quart carton of it.
Now, divide 7.04 by that number to find the price per cup.
7.04 / 16 = 0.44.
Therefore, the price per cup is $0.44 per cup.
