Two roots of the equation are,

⇒x = 4.55, - 0.55

We have to given that,

A curve has the equation,

⇒ y = 2x² - 8x - 5

Now, We know that,

If the curve intercept at x - axis, then y value is zero.

Hence, We get;

⇒ y = 2x² - 8x - 5

⇒ 0 = 2x² - 8x - 5

⇒ 2x² - 8x - 5 = 0

By quadratic formula, we get;

⇒ x = (- (- 8)) ± √(- 8)² - 4×2×- 5) / 2×2

⇒ x = (8 ± √64 + 40) / 4

⇒ x = (8 ± 10.2) / 4

Take positive sign,

⇒x = (8 + 10.2) / 4

⇒ x = 18.2/4

⇒ x = 4.55

Take negative sign,

⇒ x = (8 - 10.2) / 4

⇒ x = - 2.2/4

⇒ x = - 0.55

The true statement about the situation is:  Eugene calculates the mean number of books for this group of students.

The correct answer would be: He calculates the mean number of books for this group of students.

The statement "Eugene randomly selects a group of students at his high school using their ID numbers" implies that Eugene has randomly chosen a subset of students from the high school population. This random selection ensures that the sample represents the larger student body, reducing potential bias in the results.

Following the selection process, Eugene proceeds to ask the group about the number of books they read over the summer. This data collection allows him to gather information on the reading habits of the selected students. By asking each student in the group, he aims to capture a range of responses that will contribute to the overall analysis.

Once Eugene has collected the data on the number of books read by each student, he proceeds to calculate the mean number of books for this group. The mean, also known as the average, is obtained by summing up the number of books read by each student and dividing it by the total number of students in the group. This statistical measure provides a central tendency for the data, indicating the typical number of books read by the students in the selected group.

The area of the circle circumscribed about the right triangle with legs 6 and 8 is approximately 78.54 square units.

To find the area of the circle circumscribed about a right triangle, we can use the fact that the diameter of the circle is equal to the hypotenuse of the right triangle. In this case, the legs of the right triangle are given as 6 and 8.

Using the Pythagorean theorem, we can find the length of the hypotenuse:

[tex]c^2 = a^2 + b^2[/tex]

where c is the length of the hypotenuse, and a and b are the lengths of the legs.

Substituting the values:

[tex]c^2 = 6^2 + 8^2[/tex]

[tex]c^2 = 36 + 64\\ c^2 = 100[/tex]

Taking the square root of both sides:

[tex]c = \sqrt{100} \\ c = 10[/tex]

Therefore, the length of the hypotenuse is 10 units.

Since the diameter of the circumscribed circle is equal to the hypotenuse, the radius of the circle is half the length of the hypotenuse, which is 10/2 = 5 units.

Now we can calculate the area of the circle using the formula:

Area = π [tex]r^2[/tex]

where r is the radius of the circle.

Area = π [tex]5^2[/tex]

Area = π × 25

Area = 78.54 square units

Hence, the area of the circle circumscribed about the right triangle with legs 6 and 8 is approximately 78.54 square units.

Answer:

1,751 pieces of gum.

Step-by-step explanation:

To calculate the total number of pieces of gum, we need to consider the full boxes and the open box.

The number of pieces in each full box is 12 dozen, which is equivalent to 12 x 12 = 144 pieces per box.

Since there are 12 full boxes, the total number of pieces in those boxes is 12 x 144 = 1,728 pieces.

The open box has 23 pieces of gum.

To find the total number of pieces of gum, we add the pieces from the full boxes to the pieces in the open box:

Total = Pieces in full boxes + Pieces in open box

Total = 1,728 + 23

Total = 1,751

Therefore, there are a total of 1,751 pieces of gum.

y = 2sin(2πx) + 1 is an amplitude-scaled, period-halved, vertically shifted version of y = sin(x). It is important to note that y = cos(x) is not directly related to y = 2sin(2πx) + 1 as it represents a different trigonometric function.

The equation y = 2sin(2πx) + 1 is related to y = sin(x) and y = cos(x) through trigonometric transformations. Let's break down the relationship:

Amplitude: The coefficient 2 in front of sin(2πx) in y = 2sin(2πx) + 1 indicates that the amplitude of the sine function has been doubled compared to y = sin(x). The amplitude determines the maximum and minimum values of the function.

Period: In y = 2sin(2πx) + 1, the argument of sin(2πx) is 2πx, resulting in a period that is halved compared to y = sin(x). The period is the length of one complete cycle of the function.

Phase shift: There is no phase shift in y = 2sin(2πx) + 1. The function y = sin(x) has a phase shift of 0.

Vertical shift: The constant term +1 in y = 2sin(2πx) + 1 represents a vertical shift upward by 1 unit compared to y = sin(x). It shifts the entire graph vertically.

Overall, y = 2sin(2πx) + 1 is an amplitude-scaled, period-halved, vertically shifted version of y = sin(x). It is important to note that y = cos(x) is not directly related to y = 2sin(2πx) + 1 as it represents a different trigonometric function.

In the given statement, there is an error in the inequality. The correct statement should be:

The three-part inequality - 5x < 15x^2 < 3 is equivalent to - 6 ≤ 5 - x and 5 - x < 6.

When solving the three-part inequality - 5x < 15x^2 < 3, we need to split it into two separate inequalities. The correct splitting should be:

- 5x < 15x^2 and 15x^2 < 3

Simplifying the first inequality:

- 5x < 15x^2

Dividing by x (assuming x ≠ 0), we need to reverse the inequality sign:

- 5 < 15x

Simplifying the second inequality:

15x^2 < 3

Dividing by 15, we get:

x^2 < 1/5

Taking the square root (assuming x ≥ 0), we have two cases:
