A number generator was used to simulate the percentage of students in a town who enjoy playing video games. The process simulates randomly selecting 100 students from the town and was repeated 20 times. The percentage of students who play video games is shown in the dot plot. Which statement is true about the student population of the town?

Answer:

A

Step-by-step explanation:

The volume (V) of a pyramid is calculated using the formula

V = [tex]\frac{1}{3}[/tex] × area of base × height

note the height = 48 × 10 = 480 ( 48 storeys at 10 feet )

V = [tex]\frac{1}{3 }[/tex] × 571,536 × 480

  = 91,445,760 ft³

[ 1 yd³ = 27 ft³ ], hence

V = [tex]\frac{91445760}{27}[/tex] = 3, 386, 880 yd³ → A

Step-by-step explanation:

It is less than 50% and more tha 10%

It’s B I just took the test or quiz

bearing in mind that the derivative of s(t) is s'(t) = velocity, thus

[tex]\bf s(t)=-2-6t\implies \left. \cfrac{ds}{dt}=-6 \right|_{t=2}\implies -6[/tex]

namely a negative rate, so the object is slowing down to a stop.

Answer:

the instantaneous velocity at t = 2 is -6

Step-by-step explanation:

The position of an object at time t is given by s(t) = -2 - 6t

To find instantaneous velocity we take derivative s'(t)

s(t)= -2-6t

s'(t)= 0 -6=-6

To find instantaneous velocity at t= 2, we plug in 2 for t

there is no 't' in s'(t)

so s'(2)= -6

the instantaneous velocity at t = 2 is -6

Answer:

8x^2 - 14xy + 3y^2

Step-by-step explanation:

You need to find the product of (2x - 3y )(4x - y ). To solve this, we're going to be using the distributive distribution as follows:

(2x - 3y )(4x - y ) = 8x^2 - 2xy - 12xy + 3y^2

Combining like-terms:

(2x - 3y )(4x - y ) = 8x^2 - 14xy + 3y^2

Therefore, the result is: 8x^2 - 14xy + 3y^2

Final answer:

The function print_total_inches is defined to calculate the total number of inches by converting feet to inches and adding any extra inches. It multiplies the number of feet by 12 (since there are 12 inches in a foot) and adds the number of inches to get the total.

Explanation:

To define the function print_total_inches, we need to convert both feet and inches to inches only, since there are 12 inches in a foot. For the parameters num_feet and num_inches, the total number of inches is given by the formula total_inches = num_feet * 12 + num_inches. Here's an example of how the Python function might look:

   def print_total_inches(num_feet, num_inches):
       total_inches = num_feet * 12 + num_inches
       print('Total inches:', total_inches)

When you call print_total_inches(5, 8), it will output "Total inches: 68" because 5 feet is equivalent to 60 inches (5 x 12), and adding the additional 8 inches gives us a total of 68 inches.

[tex]\displaystyle\\\frac{22}{10}=\frac{x}{12}=\frac{33}{y}\\\\\frac{22}{10}=\frac{x}{12}\implies~x=\frac{22\times12}{10}=\frac{264}{10}=\boxed{\bf26.4}\\\\\frac{22}{10}=\frac{33}{y}\implies~y=\frac{10\times33}{22}=\frac{10\times3}{2}=5\times3=\boxed{\bf15}[/tex]

Approach: Difference of Squares Pattern

[tex]4 {x}^{2} - 25 = (2x - 5)(2x + 5)[/tex]

Step-by-step explanation:

The given binomial is:

[tex]4 {x}^{2} - 25[/tex]

We can rewrite to obtain:

[tex] {(2x)}^{2} - {5}^{2} [/tex]

This is a difference of two squares, so we will factor using difference of squares pattern.

Recall that:

[tex] {a}^{2} - {b}^{2} = (a + b)(a - )[/tex]

If we let

[tex]a = 2x[/tex]

and

[tex]b = 5[/tex]

Then we can factor the given binomial to obtain:

[tex] {2x}^2 - {5}^{2} = (2x - 5)(2x + 5)[/tex]

[tex] \therefore4 {x}^{2} - 25 = (2x - 5)(2x + 5)[/tex]

Answer:

176 cubic feet

Step-by-step explanation:

volume of each box is given by area of base * height.

Volume of Box 1 = 16 * 3 = 48

Volume of Box 2 = 16 * 3 = 48

Volume of Box 3 = 16 * 5 = 80

Total Volume = 48 + 48 + 80 = 176 ft^3

To calculate the total volume of the three boxes, we sum the individual volumes of two boxes at 48 cubic feet each and one box at 80 cubic feet, resulting in a total of 176 cubic feet.

To find the total volume of the three boxes shipped on a truck, we need to calculate the volume of each box and then sum the volumes. The volume of a rectangular prism (which is the shape of the boxes) is calculated by the formula Volume = length × width × height. In this case, the boxes have a common base of 16 square feet.

The two boxes with a height of 3 feet each have a volume of 16 square feet × 3 feet = 48 cubic feet per box. For both, this gives us a total of 48 cubic feet × 2 = 96 cubic feet.

The third box with a height of 5 feet has a volume of 16 square feet × 5 feet = 80 cubic feet.

Adding the volumes of all three boxes together, the total volume is 96 cubic feet + 80 cubic feet = 176 cubic feet. This is the total volume of the three boxes combined.

Final answer:

The recursive rule for the given sequence is [tex]a_n = a_{n-1} - 13.8[/tex],

where a₁ = -7.4 and n > 1.

Explanation:

You are looking for the recursive rule for the sequence -7.4, -21.2, -35, -48.8, -62.6, and so on. To find this, we observe how the sequence progresses from one term to the next. The pattern here is that each term decreases by the same amount when compared to the previous term. By calculating the difference between successive terms, we can identify the common difference.

For instance, the second term (-21.2) minus the first term (-7.4) equals the third term (-35) minus the second term (-21.2), and this difference equals -13.8. Hence, each term is -13.8 less than the term before it.

To express this as a recursive formula, we start by stipulating the first term:

Then, we provide the recursive rule that relates each term to the one before it:

Using this recursive formula, given any term in the sequence, we can find the next term by subtracting 13.8 from the given term.

The equation of the tangent plane to the surface x=h(y,z) at the point (3,0,3) given that ∂h/∂y=−5 and ∂h/∂z=−3 is x = -5y -3z + 12.

In Mathematics, the equation for the tangent plane to a surface x = h(y,z) at a point can be determined by the following formula: x - x0 = ∂h/∂y(y - y0) + ∂h/∂z(z - z0). In your expression ∂h/∂y (derivatives of h with respect to y) is given as -5 and ∂h/∂z (derivatives of h with respect to z) is given as -3. By plugging the value of these derivatives and the point (3,0,3) into the formula, the equation of the tangent plane would be: x - 3 = -5(y - 0) - 3(z - 3).

After simplifying this, we'll get x = -5y -3z + 12. It's worth noting that derivation of the equation for a tangent plane to a parametrized surface relies heavily on partial derivatives and the study of multi-variable calculus.

Answer:

the area of the hexagon is approx. 187.1 in²

Step-by-step explanation:

Picture this regular polygon as being a hexagon made up of six equilateral triangles of side 12 in.  We find the area of one such triangle and then multiply that by 6 to obtain the total area of the hexagon.

One such equilateral triangle has three sides all of length 12 in, and all the interior angles are 60°.  The height of one such triangle is

h = (12 in)sin 60°, or

                  √3

h = (12 in) -------- = 6√3 in

                     2

So, with base 12 in and height 6√3 in, the area of one such equilateral triangle is

A = (1/2)(12 in)(6√3 in) = 36√3 in²

and the total area of the hexagon is 6(36)√3 in², or approx. 187.1 in²

  an = 5·2^(n-1)

Step-by-step explanation:

The explicit formula for a geometric sequence with first term a1 and common ratio r is ...

  an = a1·r^(n-1)

Your sequence has a1=5 and r=2, so the explicit formula is ...

  an = 5·2^(n-1)

Final answer:

The explicit formula for the geometric sequence 5, 10, 20, 40, 80, 160,... is ,[tex]a_{n}=5(2^{n-1} )[/tex], where 'aₙ' represents the nth term in the sequence.

Explanation:

The student is asking for the explicit formula for a given geometric sequence. In mathematics, a geometric sequence is one where any term after the first is found by multiplying the previous term by a fixed, non-zero number known as the common ratio. Looking at the sequence provided (5, 10, 20, 40, 80, 160,...), we can observe that each term is twice the previous term, thus the common ratio is 2.

To find the explicit formula of a geometric sequence, we use the formula ,[tex]a_{n}=a_{1} (r^{n-1} )[/tex], where an is the nth term, a₁ is the first term in the sequence, r is the common ratio, and n is the term number. For this sequence, a₁ is 5, and r is 2.

The explicit formula for the given geometric sequence is therefore [tex]a_{n}=5(2^{n-1} )[/tex].
