Millions of students take statistics each year! Researchers hoping to help professors teach better conducted a study in statistics classrooms. They had the same instructor teach three different classes, with randomly assigned students, with three different methods! Method A - traditional lectures, with homework outside of class. Method B - flipped classroom, with students watching videos of lectures and working on homework in class with peers and instructor. Method C - fully online, with students watching videos of lectures, with homework outside of class. They then gave each class the same final exam (out of 20 points). These were the results:

The area of a rectangular wall of a barn is 144 square feet. Its length is 10 feet longer than the width. Find the length and width of the wall of the barn.
The width is __feet.

Answers

Answer:

8 feet

Step-by-step explanation:

Let l and w be length and width, respectively. Then:

lw=144   and

l=w+10

So:

w(w+10)=144

w²+10w-144=0

(w+18)(w-8)=0

w=8 as the width ................

The width of the rectangular wall is 8 feet.

What is an area?

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

Let l and w be length and width, respectively. Then:

l x w=144  

l = w + 10

The area will be given as;-

w(w+10)=144

w²+10w-144=0

(w+18)(w-8)=0

w = 8  and -18 ignore -18.

Therefore the width of the rectangular wall is 8 feet.

Hi, can you help me answer this question (−3x + 7) − (4x − 8)

Answers

Answer:

Let's simplify step-by-step.

−3x+7−(4x−8)

Distribute the Negative Sign:

=−3x+7+−1(4x−8)

=−3x+7+−1(4x)+(−1)(−8)

=−3x+7+−4x+8

Combine Like Terms:

=(−3x+−4x)+(7+8)

=−7x+15

Answer:

=−7x+15

Step-by-step explanation:

Answer:

15+7x

Step-by-step explanation:

(−3x+7)−(4x−8)

To find the opposite of 4x−8, find the opposite of each term.

−3x+7−4x−(−8)

The opposite of −8 is 8.

−3x+7−4x+8

Combine −3x and −4x to get −7x.

H) Slope -1/4 and y-intercept -1.5

Step-by-step explanation:

The slope of the line is determined by the formula :

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\[/tex]

We can use any two points on the line lets use the ones that are shown, (-6 , 0) and (2 , -2).

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{-2-0}{2-(-6)} \\\\m=\frac{-2}{8}\\\\m=-\frac{1}{4} \\[/tex]

and the y-intercept is shown in the graph where the line crosses the y-axis

In this case the line crosses the y-axis between -1 and -2 which is -1.5

so the value of slope is -1/4 and the value of y-intercept is -1.5 .So third option is our answer.

the average rate of change of the function f(x) on the interval -3≤x≤3 is -2.5. If (-3)=14 then which of the following is the value of f(3)?

Answers

The average rate of change of f(x) on -3 ≤ x ≤ 3 is given to be

(f (3) - f (-3)) / (3 - (-3)) = -2.5

If f (-3) = 14, then

(f (3) - 14) / (3 + 3) = -2.5

(f (3) - 14) / 6 = -2.5

f (3) - 14 = -15

f (3) = -1

¿Cuántas placas diferentes de autos se pueden formar con 3 letras, seguidas de 4 números del 0 al 9? Considere que el alfabeto letras. cuenta con 27

Answers

Answer: Se pueden hacer 196,830,000 placas distintas.

Step-by-step explanation:

Cada placa va a tener 3 letras y 4 números.

Lo primero que tenemos que hacer es contar el numero de opciones que tenemos para cada selección, donde las selecciones van a ser.

Primera letra, segunda letra, tercera letra, primer numero, etcétera.

Entonces.

Para la primera letra tenemos 27 opciones.

Para la segunda letra también tenemos 27 opciones.

Para la tercera letra también tenemos 27 opciones.

Para el primer numero tenemos 10 opciones (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)

para el segundo numero también hay 10 opciones.

Para el tercer numero también hay 10 opciones.

Answer:

7p¹⁵/ 3q¹²

Step-by-step explanation:

From the question given above,

28p⁹q¯⁵ / 12p¯⁶q⁷

To know which of option is equivalent to the above expression, we shall simplify the expression as shown below:

28p⁹q¯⁵ / 12p¯⁶q⁷

28p⁹q¯⁵ ÷ 12p¯⁶q⁷

Recall:

Xᵐ ÷ Xⁿ = Xᵐ ¯ ⁿ

Therefore,

28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (28/12)p⁹ ¯ ¯⁶q¯⁵ ¯⁷

28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (7/3) p⁹⁺⁶q¯¹²

28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (7/3) p¹⁵q¯¹²

Recall:

X¯ⁿ = 1/Xⁿ

Therefore,

(7/3) p¹⁵q¯¹² = (7/3) p¹⁵ × 1/q¹²

(7/3) p¹⁵q¯¹² = 7p¹⁵/ 3q¹²

Hence,

28p⁹q¯⁵ / 12p¯⁶q⁷ = 7p¹⁵/ 3q¹²
