Find the side of a square whose diagonal is of the given measure.
Given = 8 miles
To find the side of a square with a given diagonal length, apply the Pythagorean theorem. With a diagonal of 8 miles, the side length is calculated to be 4√2 miles.
Explanation:To find the side of a square whose diagonal is given, we can use the Pythagorean theorem. In a square, the diagonal creates two right-angled triangles, each with the square's sides as the legs.
Let the side of the square be s, and the given diagonal is 8 miles. According to the Pythagorean theorem, the diagonal (d) is calculated as d = √(s² + s²). Simplifying, this becomes d = √(2 * s²) or s = d / √2. Substituting the value of the diagonal, we get s = 8 / √2. To get rid of the radical in the denominator, we can multiply both the numerator and denominator by √2, giving us s = (8√2) / 2, which simplifies to s = 4√2 miles. Therefore, the side of the square is 4√2 miles.

Whether 1080 is cube number
The solution is, 1080 = 2*2*2*3*3*3*5, is not a cube number.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
given that,
the number is 1080
Split into prime factors
1080 = 2*2*2*3*3*3*5
so, we have,
Its not a cube
because although there are 2 triplicates there is also a 5.
as, we know that,
Note 2*2*2*3*3*3 is a cube.
so, 1080 = 2*2*2*3*3*3*5, is not a cube number.

Write the equation of the piecewise function ƒ that is represented by its graph.
Piecewise function with 3 pieces: [tex]x^2+1, 4x-8, 2[/tex]
The piecewise function ƒ that is represented by the graph in the image is:
ƒ(x) =
[tex]x^2+1, & \text{if } 0 \le x < 4 \\[/tex]
[tex]4x-8, & \text{if } 4 \le x < 5 \\[/tex]
[tex]5^2+1 = 26, & \text{if } x = 5[/tex]
This is because the graph of the function consists of three distinct pieces:
For 0≤x<4, the graph is a parabola with vertex at (0,1) and opening upwards. This suggests that the function is of the form [tex]ax^{2} +bx+c.[/tex]
We can find the values of a, b, and c by substituting the points (0,1), (1,1), and (4,16) into the equation.
This gives us the system of equations:
\begin{cases}
[tex]a \cdot 0^2 + b \cdot 0 + c = 1[/tex]
[tex]a \cdot 1^2 + b \cdot 1 + c = 1 \\[/tex]
[tex]a \cdot 4^2 + b \cdot 4 + c = 16[/tex]
\end{cases}
Solving this system gives us a=1, b=0, and c=1, so the equation of the function for this interval is [tex]x^{2} +1[/tex].
For 4≤x<5, the graph is a line with slope 4 and y-intercept −8.
This suggests that the function is of the form mx+b.
We can find the values of m and b by substituting the points (4,2) and (5,25) into the equation.
This gives us the system of equations:
\begin{cases}
[tex]4m+b = 2 \\[/tex]
5m+b = 25
\end{cases}
Solving this system gives us m=4 and b=−8, so the equation of the function for this interval is 4x−8.
For x=5, the graph is a horizontal line at y=26.
This suggests that the function is of the form c.
We can find the value of c by simply looking at the graph.
This gives us c=26, so the equation of the function for this interval is 26.
Therefore, the complete piecewise function is:
ƒ(x) =
\begin{cases}
[tex]x^2+1, & \text{if } 0 \le x < 4 \\[/tex]
[tex]4x-8, & \text{if } 4 \le x < 5 \\[/tex]
[tex]5^2+1 = 26, & \text{if } x = 5[/tex]
\end{cases}

Taylor bought 200 shares of stock for $18.12 per share last year. He paid his broker a flat fee of $30. He sold the stock this morning for $21 per share, and paid his broker 0.5% commission.
a. What were Taylor's net proceeds?
b. What was his capital gain?
Taylor's net proceeds from the sale of his stock are $4179, after paying his broker's 0.5% commission. His capital gain on the investment is $525, calculated by subtracting the total purchase cost, including the initial broker's flat fee, from the net proceeds of the sale.
a. What were Taylor's net proceeds?
To calculate Taylor's net proceeds, we need to consider the initial cost of buying the shares, any fees paid to the broker, and the amount earned from selling the shares. Here's the breakdown:
Determine initial cost: 200 shares x $18.12 per share = $3624
Add broker's fee when buying: $3624 + $30 = $3654
Subtract broker's fee when selling: $42 (0.5% of $8400 from selling 200 shares at $21 per share)
Calculate net proceeds: $8400 - $42 = $8358
b. What was his capital gain?
To find Taylor's capital gain, subtract the total cost (initial purchase cost + fees) from the total earnings after selling the shares. The calculation is as follows:

A checking account, or a savings account for other expenses (predictable), and emergencies. c. A savings account for college tuition. d. Coin jar.
Answer:
b. A checking account, or a savings account for other expenses (predictable), and emergencies.
Step-by-step explanation:
Peggy needs to pay car insurance 2 times every year.
She has divided the payment by 6 and saves that amount each month.
So, the best account in which she can save this money is - A checking account, or a savings account.
Other options are irrelevant as a 401-K retirement fund is some other type of account. It is not used for daily or monthly expenses.
Options C and D are also not correct.

No, the sample design is not a simple random sample (SRS), but a stratified random sample. In an SRS, every individual in the population has an equal chance of being chosen for the sample.
Explanation:The given sample design is not a simple random sample (SRS). In an SRS, every individual in the population has an equal chance of being chosen for the sample. However, in this case, the sample design is a stratified random sample. It involves dividing the population into groups (in this case, male and female engineers) and then selecting a sample from each group using a different sampling rate.
To determine if a sample design is an SRS, we need to ensure that each individual in the population has an equal chance of being chosen, and this probability is the same for every individual. In the case of the given example, the sample design does not meet these criteria, making it not an SRS.

Average precipitation for the first 7 months of the year, the average precipitation in toledo, ohio, is 19.32 inches. if the average precipitation is normally distributed with a standard deviation of 2.44 inches, find these probabilities.
Using the normal distribution and the central limit theorem, it is found that there is a:
a) 0.7054 = 70.54% probability that a randomly selected year will have precipitation greater than 18 inches for the first 7 months.b) 0.8869 = 88.69% probability that five randomly selected years will have an average precipitation greater than 18 inches for the first 7 months.Normal Probability Distribution
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem:
The mean is of 19.32 inches, hence [tex]\mu = 19.32[/tex].The standard deviation is of 2.44 inches, hence [tex]\sigma = 2.44[/tex].Item a:
The probability that a randomly selected year will have precipitation greater than 18 inches for the first 7 months is 1 subtracted by the p-value of Z when X = 18, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{18 - 19.32}{2.44}[/tex]
[tex]Z = -0.54[/tex]
[tex]Z = -0.54[/tex] has a p-value of 0.2946.
1 - 0.2946 = 0.7054.
0.7054 = 70.54% probability that a randomly selected year will have precipitation greater than 18 inches for the first 7 months.
Item b:
Now, we want the probability that five randomly selected years will have an average precipitation greater than 18 inches for the first 7 months, hence:
[tex]n = 5, s = \frac{2.44}{\sqrt{5}}[/tex]
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{18 - 19.32}{\frac{2.44}{\sqrt{5}}}[/tex]
[tex]Z = -1.21[/tex]
[tex]Z = -1.21[/tex] has a p-value of 0.1131.
1 - 0.1131 = 0.8869.
0.8869 = 88.69% probability that five randomly selected years will have an average precipitation greater than 18 inches for the first 7 months.
