Answer:
D. 343 3/4
Step-by-step explanation:
1 inch = 125 miles
There is a distance of 2 3/4 inches
The first thing you would do is double 125, since it is one inch, and 2 inches would another 125. Now you have 250. To get the rest, you would need to divide 125 by 4, getting 31.25. Now since the question needs 3/4 of 125, you multiply 31.25 by 3, which is 93.75. Now add 250, and 93.75. You get 343.75, or 343 3/4

What is the fraction?
Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many parts of a particular size there are when used in conversational English.
We have,
8⁻¹ / 4⁻¹ - a⁻¹ = 1
By simplifying the given equation we get,
8⁻¹ - a⁻¹ = 1 * 4⁻¹
By further calculating the equation,
1/8 - 1/a = 1/4
4(1/8 - 1/a) = 1
4/8 - 4/a = 1
1/2 - 4/a = 1
4/a = 1/2
1/a = 4/2
a = 2/4
a = 2
Hence, the value of the a is 2.

A student is trying to solve the set of two equations given below:Equation A: x + z = 6 Equation B: 2x + 4z = 1Which of the following is a possible step used in eliminating the z-term? (5 points)Multiply equation B by 4.Multiply equation A by 2.Multiply equation A by −4.Multiply equation B by 2.
System of Equations
Given the system of equations:
x + z = 6
2x + 4z = 1
To solve the system by the elimination method, we must make the coefficients of one variable opposite.
It's required to eliminate the z-term which means we must make the coefficients of z opposite on both equations.
The coefficient of z is 4 in the second equation, so to eliminate the variable, we must multiply the first equation by -4 as follows:
-4x - 4z = -24
Now when we add both equations, the z is eliminated.
Answer: Multiply equation A by −4.

Find the demand function for the marginal revenue function. Recall that if no items are sold, the revenue is 0. R'(x) = 0.06x2 – 0.05x + 152 p(x) = 0
The marginal revenue function, locate the demand function is P = 0.02x² -0.025x + 152 when R'(x) = 0.06x² - 0.05x + 152.
Given that,
We have to find for the marginal revenue function, locate the demand function.
Remember that the income is zero if no things are sold:
R'(x) = 0.06x² - 0.05x + 152
p(x) is what.
We know that,
MR = dTR/dx = 0.06x² - 0.05x + 152
Integrating the marginal revenue function , we get total revenue function,
MR = TR
= (0.06x²⁺¹)/(2+1) - (0.05x¹⁺¹)/(1+1) + 152x
= (0.06x³)/3 - (0.05x²)/2 + 152 x
TR = 0.02 x³ - 0.025 x² + 152 x
TR = (P)(Q) = (P)(x) = 0.02 x³ - 0.025 x² + 152 x
P = ( 0.02 x³ - 0.025 x² + 152 x)/x
P = 0.02x² -0.025x + 152
Therefore, The marginal revenue function, locate the demand function is P = 0.02x² -0.025x + 152 when R'(x) = 0.06x² - 0.05x + 152.

The probability that both Event A (the first die is 4 or less) and Event B (the second die is even) will occur is 1/3.
What is the probability that both events will occur?To find the probability that both Event A and Event B will occur, we need to calculate the individual probabilities of each event and then multiply them together.
Event A: The first die is 4 or less.
There are 6 possible outcomes for the first die (numbers 1 to 6), and out of those, 4 outcomes (numbers 1, 2, 3, and 4) satisfy the condition. Therefore, the probability of Event A is 4/6, which simplifies to 2/3.
Event B: The second die is even.
For a fair six-sided die, there are 3 even numbers (2, 4, and 6) out of a total of 6 possible outcomes. Therefore, the probability of Event B is 3/6, which simplifies to 1/2.
To find the probability that both events will occur, we multiply the probabilities of Event A and Event B:
Probability of both events occurring = Probability of Event A * Probability of Event B
P = (2/3) * (1/2)
P = 2/6
P = 1/3

suppose that the 13th term of an arithmetic sequence is 46 and the fourth term is 100. find the expression for the general term.
To solve this problem, we need to use the formula for the nth term of an arithmetic sequence:
an = a1 + (n-1)d where a1 is the first term, d is the common difference, and n is the term number. This means that the first term is 118, the common difference is -6, and each subsequent term is found by subtracting 6 from the previous term.
We know that the 4th term is 100, so we can substitute this into the formula:
a4 = a1 + (4-1)d
100 = a1 + 3d
Similarly, we know that the 13th term is 46:
a13 = a1 + (13-1)d
46 = a1 + 12d
Now we have two equations with two unknowns (a1 and d), which we can solve by elimination or substitution. I will use elimination:
100 = a1 + 3d
-46 = -a1 - 12d
------
54 = -9d
d = -6
Now we can substitute d back into one of the equations to solve for a1:
100 = a1 + 3(-6)
a1 = 118
Therefore, the expression for the general term of the arithmetic sequence is:
an = 118 - 6(n-1) or an = 124 - 6n

There are 8 red, 4 green, and 6 blue point on a circle. All the points are distinct. Find the number of triangles with vertices of three different colors.
To find the number of triangles with vertices of three different colors, we need to consider the combinations of colors we can choose from the given set of points.
We have 8 red points, 4 green points, and 6 blue points. To form a triangle with vertices of three different colors, we need to choose one point from each color group.
First, let's choose one red point. We have 8 options for this.
Next, let's choose one green point. We have 4 options for this.
Finally, let's choose one blue point. We have 6 options for this.
To determine the total number of triangles, we need to multiply the number of options for each color:
Total number of triangles = Number of options for red points × Number of options for green points × Number of options for blue points
= 8 × 4 × 6
= 192
Therefore, there are 192 triangles with vertices of three different colors.
It's worth noting that the order in which we choose the points does not matter because we are counting the number of distinct triangles. So, we are not considering permutations but rather combinations of colors.

Determine whether the statement is true or false. If it is false, rewrite it as a true statement. A sampling distribution is normal only if the population is normal. Choose the correct answer below. A. The statement is true. B. The statement is false. A sampling distribution is normal only if n≥30. C. The statement is false. A sampling distribution is normal if either n≥30 or the population. D. The statement is false. A sampling distribution is never normal.
A sampling distribution is normal only if the population is normal. This statement is false because A sampling distribution is normal only if n≥30.
If the underlying population is normally distributed, the sampling distribution (such as the sample mean distribution, also known as the xbar distribution) is also normally distributed. Even though the population is not normally distributed, the x(bar) distribution is approximately normal if n > 30, due to the central limit theorem. Some textbooks may use values above 30, but after a certain threshold the x(bar) distribution is effectively "normal".
Option B is close, but misses the normal population part. n > 30 is not necessary if we know the population is normal.
A sampling distribution is the probability distribution of a statistic obtained from a large number of samples drawn from a particular population. The sampling distribution for a given population is the frequency distribution of a range of different outcomes that can occur in the population.
In statistics, a population is the entire basin from which a statistical sample is drawn. A population can refer to an entire population of people, objects, events, hospital visits, or measurements. Thus, a population can be said to be a global observation of subjects grouped by common characteristics.

Find the exact values of s in the interval \( [-2 x, \pi) \) that satisfy the given condition \( \cot ^{2} s=3 \) \( 5= \)
The exact values of \(\( s \)\) in the interval \(\([-2\pi, \pi)\)\) that satisfy the condition \\((\cot^2 s = 3\) are \( s = \pm \frac{\pi}{3} \)\).
To find the values of \(\( s \)\) that satisfy the equation \(\(\cot^2 s = 3\)\), we need to take the square root of both sides: \(\(\cot s = \sqrt{3}\)\). Since the cotangent function is positive in the interval\(\([-2\pi, \pi)\)\), we can focus on the positive value of \(\(\sqrt{3}\)\).
The positive value of \(\(\sqrt{3}\)\) corresponds to a reference angle of \(\(s = \frac{\pi}{3}\)\)in the first quadrant. Since the cotangent function has a period of \(\(\pi\)\), we can also find another solution in the fourth quadrant. In the fourth quadrant, the reference angle is \(\(s = -\frac{\pi}{3}\)\).
Therefore, the exact values of\(\(s\)\) that satisfy the equation \(\(\cot^2 s = 3\)\) in the interval \(\([-2\pi, \pi)\) are \(s = \frac{\pi}{3}\) and \(s = -\frac{\pi}{3}\)\).
