The length of a rectangular table is two times its width. If the perimeter of
the table is 2,000 ft, set up an equation to find the width (w) of the table.
1. 2000 = 2(2W + W)
2. 1000 = 2(3W+ W)
3. 2000 = 2(2wx W)
4. 2000 = 2(3wx w)
Answer:
1. 2000 = 2(2W + W)
Step-by-step explanation:
perimeter = 2(L + W)
L = 2W, so:
perimeter = 2(2W + W)

Answer:
[tex]\sqrt[4]{7.5^{4} }[/tex]
Step-by-step explanation:
Using the rule of exponents/ radicals
[tex]a^{\frac{m}{n} }[/tex] ⇔ [tex]\sqrt[n]{a^{m} }[/tex]
Given
[tex]7.5^{1.25}[/tex]
= [tex]7.5^{\frac{5}{4} }[/tex]
= [tex]\sqrt[4]{7.5^{4} }[/tex]
[tex]\sqrt[4]{7.5^{5} }[/tex] is the radical for [tex]7.5^{1.25}[/tex].
What are exponent rules?Exponent rules, which are also known as the 'laws of exponents' or the 'properties of exponents' make the process of simplifying expressions involving exponents easier. These rules are helpful to simplify the expressions that have decimals, fractions, irrational numbers, and negative integers as their exponents.
Given
[tex]7.5^{1.25}[/tex]
We can write 1.25 is [tex]\frac{5}{4}[/tex]
[tex]7.5^{\frac{5}{4} }[/tex]
Using the rule of exponents/radicals
[tex]a^{\frac{m}{n} }[/tex] = [tex]\sqrt[n]{a^{m} }[/tex]
[tex]7.5^{\frac{5}{4} }[/tex] = [tex]\sqrt[4]{7.5^{5} }[/tex]
[tex]\sqrt[4]{7.5^{5} }[/tex] is the radical for [tex]7.5^{1.25}[/tex].

Kiera’s middle school is conducting a survey to determine the winter dance theme. Which of the following best describes a random sample?
1 point
A. All of the students in Mrs. Jackson’s class are surveyed
B. Fifty student’s names from each grade are drawn from a hat
C. Fifty randomly selected staff members are surveyed
D. Fifty randomly selected 7th graders are surveyed
The best description of a random sample for Kiera's middle school survey to determine the winter dance theme is option D: Fifty randomly selected 7th graders are surveyed.
What is random sampling?Random sampling is a technique for picking a sample from a population in such a manner that each possible sample has a preset probability of being chosen.
As per the question, the sample should be representative of the entire student population, so selecting fifty students from each grade (option B) or all the students in Mrs. Jackson's class (option A) may not be representative of the entire student population.
Similarly, selecting fifty randomly selected staff members (option C) may not be representative of the student population.
Therefore, option D is the best choice as it randomly selects students from the population of interest.

(a) Is this sample biased or unbiased? Explain your reasoning in complete sentences.
(b) Suggest another method she could use to survey people in the area that would get an unbiased result.
Answer:
this is so easy like just put variables a in b
Step-by-step explanation:
hope you get it
The Question is what is the mean of the snakes lengths. The mean means you line all of your numbers up in order then you add all of the numbers up and when you get the total you divide the total plus the amount of numbers you have. So in this case the numbers would be: 8,17,22,39,44..next you would add all them up so it would be the next step would be to count the numbers up and divide that by the total...so it will be 5/130=26 so the mean for this question will be 26....hope it helps :)

Both numbers have to be the same for it to be equal: More info below.
The answer is a) because 8 divided by 2 is 4, and 12 divided by 3 is also 4.
It is not b) because 6 divided by 2 is 3, but 12 divided by 3 is 4.
Not c) because 9 divided by 2 is 4.5, and 12 divided by 3 is 4.
Not d) because 10 divided by 2 is 5, and 12 divided by 3 is 4.
Therefore, the answer is a) 8/12.

A truck delivers 14,000 pounds of gravel.
How many tons are in 14,000 pounds?
Answer:
7000
Step-by-step explanation:
Thus the truck delivers 7 tons of gravel.
What is a unit conversion?"A unit conversion expresses the same property as a different unit of measurement. A conversion factor is a ratio that expresses how many of one unit is equal to another unit".
For the above situation,
A truck delivers 14,000 pounds of gravel.
We know that,
1 US ton = 2000 pounds
Thus, 14000 pounds = [tex]\frac{14000}{2000}[/tex]
⇒ [tex]7 tons[/tex]
Hence we can conclude that the truck delivers 7 tons of gravel.

Answer:
A=326.85 in² , C=64.09 in
Step-by-step explanation:
Area of a circle= πr²
r=10.2 in
Plug into a calculator
A=π(10.2 in)² = 326.85129....≈326.85 in²
Circumference = 2πr
C=2π(10.2) = 64.08849...≈64.09 in
In a local car lot, 1/6
of the cars have standard transmissions. Find the
probability that 3 of 4 randomly-selected cars have standard transmissions.
Answer: [tex]\dfrac{5}{324}[/tex]
Step-by-step explanation:
Given
Probability that car has a standard transmission is [tex]\frac{1}{6}[/tex]
So, the probability that the car does not have transmission is
[tex]1-\dfrac{1}{6}=\dfrac{5}{6}[/tex]
Probability of that 3 out of 4 randomly selected cars have standard transmissions is given by selecting 3 cars with standard deviation and then multiply by their respective probabilities
[tex]\Rightarrow P=^4C_3\cdot \left(\dfrac{1}{6}\right)^3\cdot \left(\dfrac{5}{6}\right)\\\\\Rightarrow P=4\times\dfrac{5}{6^4}\\\\\Rightarrow P=\dfrac{20}{1296}\\\\\Rightarrow P=\dfrac{5}{324}[/tex]
