Answer:

D)

Step-by-step explanation:

The greater the value on top (numerator) is to the bottom number (denominator), the bigger the fraction.  If you are unsure between two numbers, convert them to decimals (divide numerator by denominator) and compare.

Convert all these fractions to decimals and arrange from least to greatest, as the question asks for:

2/13 (0.153846...), 5/9 (0.555...), 4/7 (0.571428...), 5/8 (0.625).

The answer that matches this pattern is D, so that is the correct answer.

Hi there!

\(\large\boxed{k = 5}\)

Given:

y = kx

Substitute in given x and y values into the equation to solve for "k":

0.7 = k(.14)

0.7/(.14) = k

k = 5

Fill in the remainder of the table by multiplying each "x" value by 5 or dividing each given "y" value by 5:

3.1 × 5 = 15.5

2.5 × 5 = 12.5

1.2 × 5 = 6

0.3 ÷ 5 = 0.06

0.1 ÷ 5 = 0.02

ANSWER

D. y = -5x + 3

EXPLANATION

The equation of a line in slope-intercept form is,

Where m is the slope and b is the y-intercept.

In this graph, we can see that the y-intercept - which is the value of y where the line intersects the y-axis, is 3,

To find the slope, we will use the second point shown in the graph above. The formula to find the slope of a line passing through points (x₁, y₁) and (x₂, y₂) is,

Using the points (0, 3) and (1, -2),

Hence, the equation of the line is y = -5x + 3.

The length of AC after dilation will be 20. Then the measure of the angle ∠A' will be 37°.

We have given that,

AABC is dilated by a factor of 4 to produce AA'B'C'.

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

The triangle ΔABC is dilated by a factor of 4 to produce the triangle ΔA'B'C'.

Then the length of AC after dilation. We have

A'C' = scale factor x AC

A'C' = 4 x 5

A'C' = 20

Then the measure of the angle ∠A' will be

There is no effect of dilation on the angle.

∠A = ∠A' = 37°

Thus, the correct option is A.

For the given problem, the objective function is to maximize 5x₁ + 8x₂ subject to the constraints 3x₁ + x₂ ≤ 6, 2x₁ + 4x₂ ≥ 5, x₁ ≥ 1, and x₂ ≥ 0.

To solve this problem, we can use the graphical method. Firstly, we plot the feasible region by graphing the inequalities and finding the overlapping region. The feasible region is the area where all the constraints are satisfied. In this case, the feasible region is a polygon bounded by the lines 3x₁ + x₂ = 6, 2x₁ + 4x₂ = 5, x₁ = 1, and x₂ = 0. Next, we evaluate the objective function 5x₁ + 8x₂ at the vertices of the feasible region. The vertex that gives the maximum value of the objective function is the optimal solution. We find the maximum by calculating the objective function at each vertex and comparing the values. In the given problem, the maximum value is obtained at one of the vertices of the feasible region. Therefore, the optimal solution lies at that vertex. The main answer would be the coordinates of that vertex.

Answer:

5/6

Step-by-step explanation:

Answer: 5/6

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

It will land on 1, Prob (land on 1) = 1/6

It will not land on 1, the probability will be given as:

Prob (not land on a 1) = 1 - 1/6

Prob (not land on a 1) = 5/6

Hence the probability that it will not land on a 1 is 5/6

Step-by-step explanation:

The parabola that forms the shape of the satellite dish has its axis of symmetry along the vertical direction, and the vertex at the bottom center of the dish. Let's assume that the vertex of the parabola is at the origin (0,0) of a coordinate system, and the opening of the dish is along the x-axis. Then the equation of the parabola is:

y = a x^2

where "a" is a constant that determines the shape of the parabola. We can find the value of "a" using the given dimensions of the dish.

At the opening of the dish, which has a diameter of 72 feet, the y-coordinate is zero. Therefore, we have:

0 = a (36)^2

Solving for "a", we get:

a = 0

This means that the equation of the parabola is simply y = 0, which is a horizontal line passing through the origin. Clearly, this is not the correct equation for the parabola.

To find the correct equation, we need another point on the parabola. We are given that the depth of the dish at its center, which corresponds to the focus of the parabola, is 9 feet. Using the definition of a parabola, we know that the distance from any point on the parabola to the focus is equal to the distance from that point to the directrix. Since the axis of symmetry is vertical, the directrix is a horizontal line located 9 feet below the vertex.

The equation of the directrix is therefore:

y = -9

We can use this to find another point on the parabola. Consider a point (x,y) on the parabola that is equidistant from the focus (0,9) and the directrix y = -9. The distance from (x,y) to the focus is:

d = sqrt(x^2 + (y-9)^2)

The distance from (x,y) to the directrix is simply y + 9. Therefore, we have:

sqrt(x^2 + (y-9)^2) = y + 9

Squaring both sides and simplifying, we get:

x^2 = 4y(18-y)

This is the equation of the parabola. We can now find the x-coordinate of the receiver, which is located at the focus (0,9). Setting y = 9 in the equation of the parabola, we get:

x^2 = 4(9)(9) = 324

Therefore, the x-coordinate of the receiver is:

x = ±18

Since the dish is 72 feet across at its opening, the receiver should be located at a distance of 36 feet from the center of the dish. Therefore, the receiver should be placed at a height of:

y = 9 + 36 = 45 feet

above the vertex of the parabola.

At 99%, the confidence level will be (26.03,33.97)

given that

"t" at confidence level 99%, will be:

\(\alpha\) = 1 - 0.99

The margin of error will be:

E = t\(\alpha\)/2df× (\(\frac{s}{\sqrt{n} }\))

The correct line of code to complete the factorial recursion method is:

int result = x × fact(x-1); this line of code utilizes recursion to calculate the factorial of x.

The if statement checks if the value of x is equal to 1, which represents the base case. If x is indeed 1, the method returns 1, as 1! is equal to 1.

If x is not 1, the line "int result = x × fact(x-1);" is executed. This line multiplies the current value of x with the factorial of (x-1), which is obtained by recursively calling the fact() method with the parameter (x-1). This recursive call continues until the base case is reached (x = 1), and then the factorial values are multiplied together as the recursion unwinds.

Ultimately, the line of code calculates and returns the factorial of x by utilizing recursion and the concept of factorial multiplication.

The pollster should survey approximately 2,401 U.S. voters to estimate the true proportion of voters who oppose capital punishment with 95% confidence and a margin of error of 2%.

In order to estimate the true proportion of U.S. voters who oppose capital punishment with a 95% confidence level and a margin of error of 2%, the pollster should survey approximately 2,401 voters.



To calculate the sample size needed for this estimation, we can use the formula:

n = (Z² * p * q) / E²

where n is the sample size, Z is the z-score corresponding to the confidence level (in this case, 1.96 for 95% confidence), p is the estimated proportion of voters who oppose capital punishment, q is the estimated proportion of voters who support capital punishment (which is 1-p), and E is the desired margin of error (in this case, 0.02).

Assuming a conservative estimate of p = q = 0.5, we can plug in the values and solve for n:

n = (1.96² * 0.5 * 0.5) / 0.02² ≈ 2,401

Therefore, the pollster should survey approximately 2,401 U.S. voters to estimate the true proportion of voters who oppose capital punishment with 95% confidence and a margin of error of 2%.



In conclusion, to estimate the true proportion of U.S. voters who oppose capital punishment with a 95% confidence level and a margin of error of 2%, the pollster should survey approximately 2,401 voters. This sample size calculation is based on the formula for calculating sample size using the z-score, estimated proportions, and desired margin of error
