Answers

Answer 1

Answer:

a) Time spent, x (minute): 50 < x ≤ 60

b) Time spent, x (minute): 20 < x ≤ 30

Step-by-step explanation:

a) The modal class is the class interval with the highest frequency in a frequency table which is 21 (right column)

b) Find the total amount of Frequency:

12 + 18 + 11 + 9 + 8 + 21 = 79

to find mid number through the data set divided by 2:

79 / 2 = 39.5

so add up the frequency till you reach 39.5 (max)

12 + 18 = 30

30 + 11 = 41   this passes through 39.5 so the median is in the 3rd row

Answers

The area of the rectangle hall is 1512.7 square m if the length 64 5/7 m and breadth 23 3/8 m​

What is the area of the rectangle?

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

The length of the rectangle = [tex]64\dfrac{5}{7}[/tex]  m = 453/7 m

The breadth of the rectangle = [tex]23\dfrac{3}{8}[/tex] m = 187/8 m

The area of the rectangle hall:

= (453/7)(187/8)  = 1512.69 ≈ 1512.7square m

Thus, the area of the rectangle hall is 1512.7 square m if the length 64 5/7 m and breadth 23 3/8 m​

Using the law of cosines, write an algebraic proof to show that the angles in an equilateral triangle must equal 60°. Use "∧" to indicate exponents. For example, type a2 as a∧2. (Hint: Let s be a length of each side and x be the angle measure; then use these variables in the law of cosines.)

Answers

The algebraic proof shows that the angles in an equilateral triangle must equal 60° each

What is trigonometry?

Trigonometry is the branch of mathematics which set up a relationship between the sides and angle of the right-angle triangles.

From the question, we are to use the law of cosines to write an algebraic proof that shows that the angles in an equilateral triangle must equal 60°.

Given any triangle ABC, the measures of angles A, B, and C by the law of cosines are

cos A = (b² + c² - a²)/2bc

cos B= (a² + c²- b²)/2ac

cos C = (a²+ b²- c²)/2ab  

Now, given that the triangle is equilateral, with each of the side lengths equal to s

That is, a = b = c = s

Then, we can write that

cos A = (s² + s² - s²)/(2s×s)

cos A = (s² )/(2s²)

cos A = 1/2

cos A = 0.5

∴ A = cos⁻¹(0.5)

A = 60°

Also

cos B = (s² + s² - s²)/(2s×s)

cos B = (s²)/(2s²)

cos B = 1/2

cos B = 0.5

∴ B = cos⁻¹(0.5)

B = 60°

and

cos C = (s² + s² - s²)/(2s×s)

cos C = (s² )/(2s²)

cos C = 1/2

cos C = 0.5

∴ C = cos⁻¹(0.5)

C = 60°

Thus,

A = 60°, B = 60° and C = 60°

Hence, the algebraic proof above shows that the angles in an equilateral triangle must equal 60° each.

What is the solution to the system of equations? (You can either do the substitution or elimination method) x - 2y = 19 x + 3y = 14 (1.-17) (-1, 17) (-17, 1) (17,-1)​

Answers

Answer:

D. (17,-1)

Step-by-step explanation:

We'll start by canceling out x. To do so, multiple the first equation by -1

-1( x - 2y)=( 19 )(-1)

This gives us:

-x +2y = -19

x + 3y = 14

Add the equations together:

→ 5y = -15

→ y = -1

Plug in y = -1 into an equation:

→ x + 3(-1) = 14

→ x - 3 = 14

→ x = 17

1. Use the following table to answer the questions: (Note: f(x) is a continuous function)
[x] -2,3,4,8
[f(x)] 7, -2, 3, 6
[f'(x)]-4.5,-0.25,1,8

a. If g(x)=f(x), is g(x) a function?

b. Find f(g(4)).
c. Write the equation of the line tangent to g at x = -2.

PLEASE SEE PHOTO! Can you explain why my answers were wrong and can you find the correct answers to all of them?

Answers

1. a. No, g(x) is not a function because f(x) is not invertible. This is because it's not a monotonic function, which we gather from the table. On the interval [-2, 3], f(x) decreases from 7 to -2, but on the following interval [3, 4], f(x) increases to 3 and becomes positive once more. At best, f(x) is locally invertible.

1. b. This is impossible to determine... We can't know g(4) without knowing for which x we have f(x) = 4, but that's not included in the table.

1. c. The slope of the tangent line to f(x) at x = -2 is f'(-2) = -4.5. Then the equation of the tangent to f(x) at x = -2 - which means it passes through the point (-2, f(-2)) = (-2, 7) - is

y - 7 = -4.5 (x - (-2))   ⇒   y = -4.5x + 16

2. Given f(x) = arctan(3x) - ln(1 + 9x²), compute the derivative:

f'(x) = 3/(1 + (3x)²) - 18x/(1 + 9x²)

f'(x) = (3 - 18x)/(1 + 9x²)

Find the critical points of f(x), where f'(x) = 0 or doesn't exist. Only the first case can happen since the denominator is never zero. So

3 - 18x = 0   ⇒   x = 1/6

is the only critical point.

Also compute the second derivative, then check its sign at the critical point:

f''(x) = (-18 - 54x + 162x²) / (1 + 9x²)²

f''(1/6) = -72/5 < 0

The negative sign indicates that x = 1/6 is the site of a local maximum of

f(1/6) = arctan(1/2) - ln(5/4) ≈ 0.241

Also check the values of f(x) at the endpoints of the interval [0, 1]:

f(0) = 0

f(1) = arctan(3) - ln(10) ≈ -1.054

So, the maximum value of f(x) on [0, 1] is f(1/6) ≈ 0.241.

A survey was given to 90 high school students. They were asked if they preferred fiction or non-fiction and if they preferred indoor or outdoor activities. Partial survey results are shown in the table.

Answers

Answer:

11% of people preferred outside and non-fiction

Step-by-step explanation:

Table attached,
10/90 = 0.11

0.11 = 11% 

The percent of students in the survey that prefer outdoor activities given they prefer non-fiction is 11%.

What is the percent?

The first step is to determine the total number of people that like fiction: 24 + 30 = 54

Now, determine the total number of people that like non-fiction: 90 - 54 = 36

The third step is to determine the total number of people that like indoor activities and non-fiction: 50 - 24 = 26

The fourth step is to determine the total number of people that like outdoor activities given they prefer non-fiction: 36 - 26 = 10

Percentage of people that prefer outdoor activities given they prefer non-fiction = (10 / 90) x 100 = 11%
