The percentage of students that use the internet for more than 402 minutes =  16%

Percentage

Percentage, often referred to as percent, is a fraction of 100. Percentage means "per 100," and denotes part a total amount. For example, 45% represents 45 out of 100.

calculate the percentage-

The empirical rule states that

68% of the population lies within 1 standard deviation of the mean

95% of the population lies within 2 standard deviations of the mean

99.7% of the population lies within 3 standard deviations of the mean

Standard Deviation

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

The percentage will be illustrated in this:

P(X > 402) = P(X > 30 + 1 × 102)

= (1-0.68) / 2

= 0.32/2

= 16%

The percentage of students that use the internet for more than 402 minutes =  16%.

Answer:

Step-by-step explanation:

Question a: Solve for c

0.9c = 17.01 - 18.9r

c = 17.01-18.9r/0.9

c = 18.9 - 2.1r

Question b: Solve for r

18.9r = 17.01-0.9c

r =  9 - [tex]\frac{0.9}{18.9}[/tex]c

r = -10/21c + 9

(0.9/18.9 = 10/21)

Question c:

It will be best to use the equation that solves for c because this helps us determine how much chicken is bought.

c = 18.9 - 2.1r

Substitute r with 3.25

c = 18.9 - 2.1(3.25)

c= 18.9 - 6.825

c = 12.075

A mathematical sentence that uses the equal sign, =, to show that two expressions are equal is known as an equation. Look for key words or phrases such as "is," "the same as," or "equals" to determine where to place the equal sign when writing a word sentence as an equation. Make an equation out of the word sentence.

A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation. Linear equations are classified into three types: point-slope, standard, and slope-intercept.

The given condition,

You have $60 and your sister has $120. You are saving $7 per week and your sister is saving $5 per week.

Let x be the time period in weeks. So we need same amount of money.

An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle. It is not necessary for the angle to be in Euclidean space if it lies in the plane. Angles are referred to as dihedral angles if they are created by the intersection of two planes in a space other than Euclidean. The sign "" is used to denote angles. The Greek letter,,, etc. can be used to represent the angle measurement between the two rays. If different types of angles, such as a positive angle and a negative angle.

Positive Angle: If angle goes in counterclockwise, then it is called a positive angle.

Negative Angle: If angle goes clockwise direction, then it is called a negative angle.

Percent of the games do not cost $1 or $2 is 35%.

A fraction of a number out of 100% is referred to as a percentage, sometimes known as a percent. Percentage refers to a portion of a total amount and signifies "per 100." For instance, 45% signifies 45% of the total or 45 out of 100.

By dividing the value by the entire value and multiplying the result by 100, one may determine the percentage. The percentage calculation formula is (value/total value)100%.

Given,

The length of the band is the number of units it covers

The actual length of the band is: \mathbf{40 + 10\pi}40+10π

The diameter of 1 pencil is given as:

\mathbf{d = 10}d=10

The circumference of 1 pencil is:

\mathbf{C = \pi d}C=πd

So, we have:

\mathbf{C = 10\pi }C=10π

Multiply by 4, to calculate the circumference of all pencils

\mathbf{4C =4 \times 10\pi }4C=4×10π

\mathbf{4C =40\pi }4C=40π

The rubber band covers a quarter of the 4 pencils.

So, we divide by 4

\mathbf{C = 10\pi }C=10π

The length of the band on one pencil is:

\mathbf{L = 10}L=10

Multiply by 4, for the 4 pencils

\mathbf{L = 40}L=40

So, the actual length of the band is:

\mathbf{Length = 40 + 10\pi}Length=40+10π

Transformation is a term that refers to movement of an image from one position to the other.

Considering that the pumpkin is on the ground at x = 0 and x = 50, it is found that:

5. The roots of the quadratic function are: r1 = 0, r2 = 50.

6. The function is written as follows: y = a(x - 0)(x - 50).

7. The leading coefficient is a = -0.0992.

8. The function is: y = -0.0992(x - 0)(x - 50).

9. Applying the distributive property, the function is: y = -0.0992(x² - 50x).

10. The graph is given at the end of the answer.

A quadratic function of roots x' and x'' is defined as follows:

y = a(x - x')(x - x'').

In the context of this problem, the roots are the values of x when the pumpkin is on the ground, hence:

x' = 0, x'' = 50.

Hence, considering the roots, the function is written as:

y = a(x - 0)(x - 50).

The maximum height obtained by the pumpkin is of 62 feet, after a horizontal distance of 25 feet(mean of the roots), hence the vertex is given by these following coordinates:

(25, 62)

The coordinates are used to find the value of a, which is the leading coefficient of the function, as follows:

62 = a(25² - 50 x 25)

62 = -625a

a = -62/625

a = -0.0992.

Then the equation is written as:

y = -0.0992(x - 0)(x - 50).

The distributive property means that the outer term multiplies each the inside terms, and then the common terms are added, hence the function is:

y = -0.0992(x² - 50x).

Which is sketched at the end of the answer.

The pumpkin is on the ground when x = 0 and x = 50.

The maximum height obtained by the pumpkin is of 62 feet, after a horizontal distance of 25 feet.
