The width of the soccer field in the drawing is 116 inches if the ratio is 2 inches to 1 yard

If 2 inches on the drawing represents 1 yard in reality, then 1 inch on the drawing represents 1/2 yard in reality.

So, to find the width of the soccer field in the drawing, we can use the following proportion:

1 inch on drawing / (1/2) yard in reality = x inches on drawing / 58 yards in reality

Simplifying this proportion, we get:

x inches on drawing = (1 inch on drawing / (1/2) yard in reality) * 58 yards in reality

x inches on drawing = 2 * 58

x inches on drawing = 116

Therefore, the width of the soccer field in the drawing is 116 inches.

The binary number 1001100 is equivalent to the decimal number 76.

HOW TO CONVERT BINARY TO DECIMAL?

To convert a number in base 2 (binary) to base 10 (decimal), we need to multiply each digit of the binary number with its corresponding power of 2 and then sum up the results. The rightmost digit corresponds to 2, the next digit to 2 the next to 2², and so on, with each successive digit corresponding to the next higher power of 2.

For example, to convert the binary number 1001100 to decimal, we would start by multiplying the rightmost digit (0) by 2 raise the power 0, which equals 1. We would then multiply the next digit (0) by 2 raise the power 1, which equals 0, and so on, until we reach the leftmost digit (1), which corresponds to 2 raise the power 6. We then add up all of these products to get the decimal equivalent of the binary number.

So, using this method, we have:

1 x 2⁶ + 0 x 2⁵ + 0 x 2⁴ + 1 x 2³+ 1 x 2² + 0 x 2¹ + 0 x 2°= 64 + 0 + 0 + 8 + 4 + 0 + 0 = 76

Therefore, the binary number 1001100 is equivalent to the decimal number 76.

With a significance level of 0.05, the. option that shows the correct test statistic, P- value, and conclusion is A. Test statistic, -1.952; P-value, 0.0414. There is sufficient evidence to reject the null hypothesis of no difference between the triglyceride test levels.

In statistics, the significance level (denoted by α) is the probability of making a Type I error, which is rejecting a true null hypothesis. In other words, it is the maximum allowable probability of observing a result as extreme as or more extreme than the one observed, assuming the null hypothesis is true.

The significance level is typically set by the researcher before conducting a hypothesis test and is usually set to 0.05 (5%) or 0.01 (1%). If the p-value of the test is less than or equal to the significance level, the null hypothesis is rejected in favor of the alternative hypothesis. If the p-value is greater than the significance level, the null hypothesis is not rejected.

The number of triangles formed or the interior angle sum to each regular polygon:

Number of triangles formed is 4 - Regular octagon

Interior angle sum is 1,440 - Regular dodecagon

Interior angle sum is 1,800 - Regular decagon

Number of triangles formed is 6 - Regular hexagon

A triangle is a geometric shape that consists of three straight line segments that are connected to form three angles. The three line segments are called sides and the three angles are located at the vertices (corners) where the sides meet.

Here,

The number of triangles formed in a regular polygon is related to the number of sides it has. For a regular polygon with n sides, the number of triangles formed is (n-2). For example, a regular hexagon has six sides, so the number of triangles formed is (6-2) = 4. The interior angle sum of a regular polygon is related to the number of sides it has as well. The formula to find the interior angle sum of a regular polygon with n sides is: Interior angle sum = (n-2) x 180 degrees

For example, a regular dodecagon has 12 sides, so its interior angle sum is (12-2) x 180 = 1,800 degrees. Similarly, a regular octagon has 8 sides, so its interior angle sum is (8-2) x 180 = 1,080 degrees.

Therefore, based on the given information, we can match the number of triangles formed and the interior angle sum to each regular polygon as follows:

Regular octagon: Number of triangles formed is 4 (column 1) and Regular octagon is matched to 1 (column 2).

Regular hexagon: Number of triangles formed is 6 (column 1) and Regular hexagon is matched to 2 (column 2).

Regular decagon: Interior angle sum is 1,800 (column 1) and Regular decagon is matched to 3 (column 2).

Regular dodecagon: Interior angle sum is 1,440 (column 1) and Regular dodecagon is matched to 4 (column 2).

d. 13.25 meters of cloth is left after making 1 shirt from a piece of cloth that is 36.25 meters long.

What is total length?

Whole Length (TL) is the measurement taken in a straight line, with the fish lying on its side, from the tip of the snout to the end of the tail (caudal fin).

(a) Total cloth required = 15 × 23 meters = 345 meters

Therefore, the total length of cloth required to make shirts for 15 students is 345 meters.

(b) Number of shirts = 9.5 meters ÷ 23 meters/shirt ≈ 0.413

Therefore, only 0 shirts can be made from a piece of cloth 9.5 meters long. We need at least 23 meters of cloth to make one shirt.

(c) 23 meters = 23.00 meters

Therefore, the length of cloth required for one shirt in decimal form is 23.00 meters.

(d) Number of shirts = 36.25 meters ÷ 23 meters/shirt ≈ 1.576

The amount of cloth left over after making 1 shirt is:

Cloth left over = 36.25 meters - 23 meters = 13.25 meters

The equation that represents dividing the rectangle into two equal parts is:

W * L/4 = A/2

Assuming that we want to divide the rectangle into two equal parts by a straight line passing through its center, we can represent the rectangle's dimensions as follows:

Let L be the length of the rectangle, and let W be its width. Then the area of the rectangle is A = L * W.

Therefore, to divide the rectangle into two equal parts, we need to draw a line that passes through the center of the rectangle and divides it into two parts with equal areas.

Let x be the distance of the dividing line from one of the shorter sides of the rectangle. Then, the length of the two parts of the rectangle is equal, which means:

L/2 - x = x

Solving for x, we get:

x = L/4

Therefore, the equation that represents dividing the rectangle into two equal parts is: W * L/4 = A/2

This equation says that if we take the width of the rectangle and multiply it by one-fourth of its length, we get half of the rectangle's area, which represents dividing it into two equal parts.

In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = rise/run

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

By substituting the given data points into the slope formula, we have the following;

Slope (m) = (18 - 15)/(2 - 0)

Slope (m) = 3/2

Slope (m) = 1.50.

At data point (0, 15), a linear equation in slope-intercept form for this line can be calculated by using the point-slope form as follows:
