Give two examples of items that weigh less than 1 ounce and two examples of items that weigh more than 1 ton.
A veterinary clinic plans to build four identical dog kennels along the side of its building using 210 feet of fencing. (See the picture.) What should be the dimensions of each kennel to maximize the enclosed area? (Note: No fencing is needed along the side of the building.)
Final answer:
To maximize the enclosed area, each kennel should be in the shape of a square with dimensions of 52.5 feet by 52.5 feet.
Explanation:
To maximize the enclosed area, each kennel should be in the shape of a square. Let's assume that each side of the square kennel has a length of x feet.
Each kennel has four sides, so the total length of fencing required for all four kennels is 4x feet.
Given that there are 210 feet of fencing available, we can set up the equation 4x = 210 and solve for x to find the length of each side of the square kennel.
Dividing both sides of the equation by 4, we get x = 52.5 feet.
Therefore, each kennel should have dimensions of 52.5 feet by 52.5 feet to maximize the enclosed area.
At the beginning of a call to the cable company, a message tells customers, “After you finish talking to our customer service representative, you will be asked to take a five-question survey about the level of service you received. It would be appreciated if you could please stay on the line to answer the survey questions.” What type of sampling is the cable company using? systematic random sampling voluntary sampling cluster sampling convenience sampling
Answer:
voluntary sampling
Step-by-step explanation:
Voluntary sampling involves someone opting to be a part of the sample. In this situation, customers are given the option to stay on the line to answer a survey; this means it is on a voluntary basis. Thus it is a voluntary sample.
The type of sampling is the cable company using is convenience sampling.
Why do we do sampling?
We do sampling so that we don't have to work on entire population of items but only on that sample in a way that we can predict information about population.
Most of the times, it isn't possible in real world to work on entire populations. Samples come out for rescue by assumptions that they will have some properties of the population pertained in them.
Thus, the sample should be taken out such that it includes data of the population as much as it can in unbiased way so as to imitate population.
We are given that;
The cable company is using convenience sampling.
Convenience sampling involves selecting individuals who are convenient or readily available to participate in the study. In this case, the cable company is selecting individuals who call their customer service and happen to complete their call with a customer service representative. The individuals are not selected based on any specific criteria or randomly selected, but rather because they happen to call the cable company and complete a customer service call.
As the message specifically invites customers to stay on the line to answer the survey questions, it can also be considered a form of voluntary sampling, where individuals are invited to participate in a study and can choose whether or not to participate.
Therefore, by sampling the answer will be convenience sampling.

The lengths of pregnancies are normally distributed with a mean of 268 days and a standard deviation of 15 days.
a. find the probability of a pregnancy lasting 309 days or longer.
b. if the length of pregnancy is in the lowest 44%, then the baby is premature. find the length that separates premature babies from those who are not premature.
Final answer:
The probability of a pregnancy lasting 309 days or longer is approximately 0.32%. Pregnancies shorter than 266 days are considered premature, which is determined based on the lowest 44% criterion.
Explanation:
The questions deal with calculating probabilities and determining specific values based on a normal distribution of pregnancy lengths, with a mean of 268 days and a standard deviation of 15 days.
a. Find the probability of a pregnancy lasting 309 days or longer.
To find this probability, we first calculate the z-score for 309 days:
Z = (X - μ) / σ = (309 - 268) / 15 ≈ 2.73.
Looking up the z-score of 2.73 in a standard normal distribution table or using a calculator with normal distribution functions, we find the area to the right is approximately 0.0032. This represents the probability of a pregnancy lasting 309 days or longer, which is 0.32%.
b. Find the length that separates premature babies from those who are not premature.
To determine the length of pregnancy that separates the lowest 44% (premature babies), we look for the z-score corresponding to the 44th percentile in a standard normal distribution table, which is approximately -0.15.
Then, we use the formula to find the specific value: X = μ + Zσ = 268 + (-0.15)(15) ≈ 266 days. Therefore, pregnancies shorter than 266 days are considered premature in this context.

A number z is fewer than 34.
Final answer:
The letter 'z' in mathematics can refer to various concepts including complex numbers with arguments measured in degrees, z-scores in statistics indicating deviation from the mean, and as a variable within equations and inequalities.
Explanation:
The concept of 'z' seems to refer to multiple mathematical contexts, including complex numbers, z-scores in statistics, and equations involving z. Specific examples from the information provided include:
Complex numbers where z's argument could be positive or negative, and use of degrees in the context of a circle's 360 degrees showing that -30 and 330 degrees represent the same angle.
The z-score, which measures how many standard deviations a data point is from the mean in statistics, such as z = -4 indicating a data point four standard deviations to the left of the mean.
Equations where z is a variable representing a number, which could be within a certain range or satisfying a given condition.
Understanding these uses of z in the mathematical context allows for precise interpretation of equations, probabilities, and analyses of data sets.
The inequality that represents the statement "A number z is fewer than 34." is: z < 3/4.
How to express the inequality?
The inequality that represents the word sentence "A number z is fewer than 3/4" is z < 3/4.
To explain this, we can compare z to 3/4. If z is smaller than 3/4, we can use the less than symbol (<) to represent this relationship.
So, the inequality is z < 3/4.
For example, if z is 1/2, which is smaller than 3/4, the inequality holds true: 1/2 < 3/4.
Complete question is:

What would be the slope of the line perpendicular to the line 4x + 2y = 12?
Final answer:
The slope of the line perpendicular to the line 4x + 2y = 12 is the negative reciprocal of the original line's slope, which in this case is 0.5 or 1/2.
Explanation:
The slope of a line perpendicular to another line is the negative reciprocal of the original line's slope. To find the slope of the line perpendicular to the line 4x + 2y = 12, we first need to rewrite the given equation in slope-intercept form (y = mx + b), where m represents the slope and b represents the y-intercept.
First, we solve for y:
4x + 2y = 12
2y = -4x + 12
y = -2x + 6
From the equation y = -2x + 6, we can see that the slope (m) is -2. The slope of the perpendicular line will be the negative reciprocal of -2, which is ½ or 0.5. Therefore, the slope of the line perpendicular to the line 4x + 2y = 12 is ½.

8 371
After plugging the x-values from the table into the equation y = 115 + 32(x) and finding matching results with the y-values in the table, it is clear that the table and equation represent the same function.
To determine if the table and the equation y = 115 + 32(x) represent the same function, we can plug the x-values from the table into the equation and see if the resulting y-values match those provided in the table.
For x = 0: y = 115 + 32(0) = 115, which matches the table.For x = 2: y = 115 + 32(2) = 115 + 64 = 179, which matches the table.For x = 4: y = 115 + 32(4) = 115 + 128 = 243, which matches the table.For x = 6: y = 115 + 32(6) = 115 + 192 = 307, which matches the table.For x = 8: y = 115 + 32(8) = 115 + 256 = 371, which matches the table.Since the y-values for all listed x-values in the table correspond exactly to those calculated using the equation, it is evident that the table and the equation do indeed represent the same function.

Lan wants to run less than 7/12 miles. It says to find out a fraction with a denominator of 4 and which is less than 7/12.
Let's assume the required fraction to be x/4 such that x/4 is less than 7/12.
[tex] \frac{x}{4} < \frac{7}{12} \\\\
3*\frac{x}{4} < \frac{7}{12}*3 \\\\
\frac{3x}{4} < \frac{21}{12} \\\\
\frac{3x}{4} < \frac{7}{4} \\\\
3x < 7 [/tex]
So we must have multiples of 3's that should be less than 7, we have only two choices 3 < 7 or 6 < 7.
It means x = 1 or x = 2, and the required fraction would be 1/4 or 2/4.
2/4 is simplified to 1/2 and the question says to have denominator 4.
Hence, final answer is 1/4

joey's little sister must take four steps for every three steps joey takes. suppose one step of joey's covers one foot. how many feet would his sister
Joey's sister takes 0.75 foot for each step she takes since she takes four steps for every three of Joey's, and Joey's step is 1 foot.
The question revolves around a ratio of steps taken by Joey and his sister. Since Joey's one step covers one foot and his sister takes four steps for his three, we need to determine how many feet his sister covers for each of Joey's steps. Let's use a ratio to figure this out.
First, we establish the ratio of steps: for every 3 steps Joey takes, his sister takes 4. If Joey's 3 steps equal 3 feet (because 1 step = 1 foot), we then find the length of his sister's step compared to his. We divide the 3 feet by Joey's 3 steps to find that each step Joey takes is 1 foot long. Then, we calculate his sister's step length in feet by dividing the 3 feet by 4 (since she takes 4 steps to his 3), which equals 0.75 foot per step for his sister.
So, for each of Joey's steps being 1 foot, his sister's step would be 0.75 foot. Therefore, Joey's sister covers 0.75 foot for each step she takes.

a rectangle has an area of 156 square inches and a perimeter of 50 in what are the width and the length of the rectangle
Final answer:
To find the length and width of the rectangle with an area of 156 square inches and a perimeter of 50 inches, we can set up and solve a system of equations based on the area and perimeter formulas. After solving, we determine that the length is 13 inches and the width is 12 inches.
Explanation:
The student has asked to find the length and width of a rectangle given that it has an area of 156 square inches and a perimeter of 50 inches. To solve this problem, we need to use the formulas for the area and perimeter of a rectangle.
Area and Perimeter Formulas
Area formula: A = length × width
Perimeter formula: P = 2(length + width)
Let's denote the length as 'l' and the width as 'w'. The area of the rectangle is 156, so we can write:
l × w = 156
The perimeter of the rectangle is 50, so we can write the perimeter formula as:
2(l + w) = 50
This simplifies to:
l + w = 25
Now, we have two equations:
l × w = 156
l + w = 25
We can solve this system of equations by expressing one variable in terms of another. Let's express 'w' in terms of 'l' from the second equation:
w = 25 - l
Now, substitute 'w' in the area equation:
l × (25 - l) = 156
This is a quadratic equation that can be solved to find the values of 'l'. Once we have 'l', we can find 'w' using the second equation.
After solving, we find that the length is 13 inches and the width is 12 inches. Therefore, the rectangle's dimensions are 13 inches by 12 inches.
