What is the margin of error for the 95% confidence interval of (0.50, 0.66) of coworkers who went on a vacation last year away from home for at least a week
Answer: Margin of Error for the given CI is 0.08
Step-by-step explanation:
Given the data in the question;
it is a symmetric class interval hence, sample proportion p = (0.50 + 0.66) / 2
p = 1.16 / 2
sample proportion p = 0.58
Margin of Error E will be;
E = 1/2 × length of Confidence interval
Margin of Error E = 1/2 × ( 0.66 - 0.5)
Margin of Error E = 1/2 × 0.16
Margin of Error E = 0.08
Therefore; Margin of Error for the given CI is 0.08
The largest species of jellyfish is the lion's mane jellyfish. One particular specimen has a diameter of 1.03 meters and tentacles that are 29 meters long. The specimen weighs 164 kilograms and can travel at a speed of 1.38 meters per second.
What is the diameter of the specimen in centimeters?
Answer:
The diameter of the specimen in centimeters is 103 cm.
Step-by-step explanation:
In order to determine the diameter in centimeters of the largest specimen of jellyfish, knowing that said diameter is 1.03 meters, and that 1 meter is equal to 100 centimeters, the following calculation must be performed:
1.03 x 100 = X
103 = X
Therefore, the diameter of the specimen in centimeters is 103 cm.

A supervisor records the repair cost for 22 randomly selected VCRs. A sample mean of $75.50 and standard deviation of $18.07 are subsequently computed. Determine the 99% confidence interval for the mean repair cost for the VCRs. Assume the population is approximately normal.
Answer:
The 99% confidence interval for the mean repair cost for the VCRs
(65.801, 85.199)
Step-by-step explanation:
Explanation:-
Mean of the sample(x⁻) = $75.50
Given the standard deviation of the sample (S) = $18.07
Given the size of the sample 'n' = 22
Degrees of freedom = n-1 =22-1 =21
critical value t₍₀.₀₁, ₂₁₎ = 2.5176
The 99% confidence interval for the mean repair cost for the VCRs
[tex](x^{-} - t_{0.01} \frac{S.D}{\sqrt{n} } , x^{-} +t_{0.01} \frac{S.D}{\sqrt{n} })[/tex]
[tex](75.50 - 2.5176 \frac{18.07}{\sqrt{22} } , 75.50 +2.5176 \frac{18.07}{\sqrt{22} })[/tex]
( 75.50 - 9.699 , 75.50 + 9.699 )
(65.801, 85.199)
Final answer:-
The 99% confidence interval for the mean repair cost for the VCRs
(65.801, 85.199)

Find the missing X- and y-values and Pythagorean triples using the identity

Write the triples in parentheses with commas but no spaces between the values, and order the values
from least to greatest.
Type the correct answer in each box.
Question:
Find the missing x- and y-values and Pythagorean triples using the identity given
[tex](x\²-y\²)\² + (2xy)\² = (x\²+y\²)\²[/tex]
[tex]x = 4[/tex]
[tex]y = 3[/tex]
Pythagorean Triples:
Write the triples in parentheses with commas but no spaces between the values, and order the values from least to greatest.
Answer:
Pythagorean triples is: (7, 24, 25)
Step-by-step explanation:
Pythagorean triples is expressed as:
[tex]a^2 + b^2 = c^2[/tex]
In [tex](x\²-y\²)\² + (2xy)\² = (x\²+y\²)\²[/tex]
[tex]a^2= (x^2 -y^2)^2[/tex]
Take square root of both sides
[tex]a = x^2 - y^2[/tex]
[tex]b^2 = (2xy)^2[/tex]
Take square root of both sides
[tex]b = 2xy[/tex]
[tex]c^2 = (x^2 + y^2)^2[/tex]
Take square root of both sides
[tex]c = x^2 + y^2[/tex]
So, we have:
[tex]x = 4[/tex]
[tex]y = 3[/tex]
Pythagorean Triples: ?
[tex]a = x^2 - y^2[/tex]
[tex]a = 4^2 - 3^2[/tex]
[tex]a = 16 - 9[/tex]
[tex]a = 7[/tex]
[tex]b = 2xy[/tex]
[tex]b = 2 * 4 * 3[/tex]
[tex]b = 24[/tex]
[tex]c = x^2 + y^2[/tex]
[tex]c = 4^2 + 3^2[/tex]
[tex]c = 16 + 9[/tex]
[tex]c= 25[/tex]
Hence, the Pythagorean triples is: (7, 24, 25)

Kyle starts saving for his first car by opening a savings account and depositing $100 . He plans to make a deposit every month to continue saving. The amount of money in Kyle's savings account can be modeled by the sequence 0=100, , =−1+75 , where is the number of months since his initial deposit. Is the sequence a function? Why or why not?
Answer:
The sequence is a function
Step-by-step explanation:
Given
Sequence: [tex]A_0=100[/tex]; [tex]A_n=A_{n-1}+75[/tex]
Required
Is the sequence a function
To determine if the sequence is a function or not, we start by calculating its range from the domain:
When n = 0; [tex]A_0=100[/tex]
When n = 1: [tex]A_1 = A_{1-1} + 75 = A_0 + 75 = 100 + 75 = 175[/tex]
When n = 2; [tex]A_2 = A_{2-1} + 75 = A_1 + 75 = 175 + 75 = 250[/tex]
When n = 3; [tex]A_3 = A_{3-1} + 75 = A_2 + 75 = 250 + 75 = 325[/tex]
This implies that:
The domain (n) and the range (An) can be represented as:
[tex]\left[\begin{array}{c}n&-&0&1&2&3\\-&-&-&\end{array}\right][/tex] [tex]\left[\begin{array}{c}A_n&-&100&175&250&325\\-&-&-&\end{array}\right][/tex]
The above shows that the sequence is a one to one relation and a one to one relation is always a function.
Answer:
Yes, because for each input value, n, there is only one possible output value.

Simplify the expression.
Write your answer without negative exponents.
Answer:
-5/ (x^19 * y^12)
Step-by-step explanation:
-15x^-10 * y ^ -3 * x^-9 * y^-9/3 (It's writing it like this.)
15 and 3 have a GCF of 3.
-5x^-10 * y^-3 * x^-9 * y^-9/1
Reduce similar occurrences. *twice in a row*
-5x^(-10 + (-9)) * y^(-3 + (-9))/1
Remove extra signs *twice in a row*
-5x^(-10 - 9) * y^(-3 - 9)/1
Remove extraneous 1.
-5x^(-10 - 9) * y^(-3 - 9)
Add integers.
-5x^-19 * y^-12
Negative powers change multiplication to division.
-5 / (x^19 * y^12) is the final answer.
Even with that, the simplified answer wouldn't have negative exponents because of the negative powers rule.
What is 0.4 as a whole number
Answer:

0.4 as a whole number would 1
What is an whole no?The number 4 cannot be rounded down to 0 because 0 is not bigger or the same as 0. 4
Instead, the number 0. 4 would be rounded up to 1, which is the closest whole number.
A whole number is a positive number that doesn't have any parts with decimals or fractions. Whole numbers are numbers that start from 0 and go up without any fractions or negative numbers. In simpler terms, whole numbers include the numbers 0, 1, 2, 3, 4, 5, and so on. They only have positive numbers and whole numbers.

Consider the equation:
X2+ 2x – 15 = 0
A) First, use the "completing the square" process to write this equation in the form
(2 + D)2= E
Answer:
x² + 2x - 15 = 0
x² + 2x + 1 = 16
(x + 1)² = 16
You can then go forward with that to solve it:
x + 1 = √16
x = -1 ± √16
x = -1 ± 4
x = 3, -5

Which selection from the list below provides the most complete and accurate description for the number of days mankind has walked the earth variable:________________
A. It is a variable that is both Quantitative and Continuous
B. It is a variable that is Discrete
C. It is a variable that is Quantitative
D. It is a variable that is neither Quantitative nor Continuous
E. It is a variable that is both Quantitative and Discrete.
Answer:
E.
Step-by-step explanation:
The variable that represents this would be both Quantitative and Discrete. This is because since this variable is measuring the amount of days it has a value type which therefore makes it a Quantative variable. Also, since the number of days that mankind has waled the Earth is a finite value, regardless of how large it may be, it would be considered to be a discrete variable. Continuous variables would be something along the lines of "What is the size of the Universe?" because the value of this variable would be neverending since we cannot calculate it.

Describe how the graph of y= x2 can be transformed to the graph of the given equation. y = x2 + 9 Shift the graph of y = x2 left 9 units. Shift the graph of y = x2 right 9 units. Shift the graph of y = x2 down 9 units. Shift the graph of y = x2 up 9 units.
Answer:
Shift of graph of y=x^2 up 9 units.
Option D is correct option.
Step-by-step explanation:
We are given:
[tex]y = x^2[/tex]
We need to describe how the graph of [tex]y = x^2[/tex] can be transformed to the graph of the given equation [tex]y=x^2+9[/tex]
We know the transformation rule:
If f(x) is transformed into f(x)+h, the graph is transformed vertically up h units.
So, In our case:
[tex]y=x^2[/tex] is transformed into [tex]y=x^2+9[/tex]
So, The graph is transformed vertically up 9 units.
Or we can write, shift of graph of y=x^2 up 9 units.
Option D is correct option.
