Answers

Answer 1

Answer:

Kindly check explanation

Step-by-step explanation:

Calculate the 25th, 50th, and 75th percentiles.

b. Calculate the interquartile range.

c. Construct a boxplot. Are there any outliers?

Reordered data:

25, 40, 52, 55, 60, 70, 70, 72, 74, 75, 75, 80, 80, 85, 85, 86, 87, 90, 92, 99

25 th percentile :

1/4 (n + 1)th, tetm

n = 20

1/4(21) = 5.25th term

(5 + 6) th term / 2

= 65

50th percentile :

1/2 (n + 1)th, tetm

n = 20

1/2(21) = 10.5th term

(10 + 11) th term / 2

= 75

75th percentile:

3/4 (n + 1)th, tetm

n = 20

3/4(21) = 15.75th term

(15 + 16) th term / 2

= 85.5

Interquartile range :

Q3 - Q1

75th percentile - 25th percentile

85.5 - 65

= 20.5

25 is an Outlier

According to the provided diagram, which depicts two congruent triangles, the measure of angle S is 27.

Congruent triangles are what?

If all 3 corresponding sides and all 3 corresponding angles are equal in size, the two triangles are said to be congruent. Slide, twist, flip, and turn these triangles to create an identical appearance.

What are the five rules for triangle congruence?

If two triangles meet all 5 requirements for congruence, then they are congruent. They are right angle-hypotenuse-side (RAHS), angle-side-angle (ASA), angle-angle-side (AAS), side-side-side (SSS), and side-angle-side (SSS) (RHS). All three equivalent sides of the acronym SSS (side-side-side) are congruent. SAS (side-angle-side) (side-angle-side) Congruence exists between two sides and the angle between them. ASA (angle-side-angle) (angle-side-angle).

Answer: Melanie has the most money at the end of the week.

Step-by-step explanation:

Melanie gets the 1 weekly allowance. But it could also depend on how much her weekly allowance is. Your bus rides aren't a lot, so riding the bus 7 times doesn't take much money. She also gets paid for 2 hours, so she could be working somewhere with more money being paid by the hour. While on the other hand, Dana could be working a minimum wage job and wasting more money, because she also pays for food. She could be on her own and have to spend more money for her needs and the things she would need. (And because it says Melanie gets 1 weekly allowance that means she still lives with her parents so they pay for her benefits and things she needs.)

Calculate the amount of money​ you'll have at the end of the indicated time​ period, assuming that you earn simple interest. You deposit ​$3400 in an account with an annual interest of 4.5 ​% for 20years. The amount of money​ you'll have at the end of the years is

Answers

Answer:

The amount of money​ you'll have at the end of the years is 6460 dollars

Step-by-step explanation:

The total principal sum of money deposited = [tex]3400[/tex] dollars

The annual rate of interest is [tex]4.5[/tex] %

The time period for which the amount is invested [tex]= 20[/tex] years

As we know

[tex]A = P (1 + rt)[/tex]

where A is the amount after 20 years

P is the principal sum of money

r is the rate of interest and

t is time period in years

Substituting the given values in above equation, we get -

[tex]A = 3400 (1 + \frac{4.5}{100} * 20)\\A = 6460[/tex]dollars

Answers

Answer:

Step-by-step explanation:

If we assume that angles 5 and 7 are vertical angles, they are congruent:

  10x -9 = 9x

  x = 9 . . . . . . . add 9-9x

Then angles 5 and 7 are ...

  (10·9 -9)° = 9·9° = 81°

Angle 6 will be the supplement to this.

CAN SOMEONE TELL ME THE AREA PLEASE

Answers

Answer:

1.3 m²

Step-by-step explanation:

The shape is a trapezoid.

Area of a trapezoid = ½(a + b)*h

Where, a = 0.8 m

b = 1.8 m

h = height of the trapezoid which is not given.

Therefore, find h using trigonometric function with 45° as reference angle:

Hypotenuse = 1.4 m

Opposite = h

Apply SOH, which is:

Sin 45 = Opp/Hyp

Sin 45 = h/1.4

1.4*Sin 45 = h

0.989949493 = h

h ≈ 1.0 m

✔️Area of Trapezoid = ½(0.8 + 1.8)*1 = 1.3 m²

The domain is determined solely by the denominator in this problem. The denominator cannot equal 0, and as a result in this problem cannot equal 8 or -8. The above answers are the results of that notion. These do not equal any form of 8, but it's perfectly fine to be negative.

Find the values of m and n.

B. m = 50, n = 20
C. m = 50, n = 16
D. m = 60, n = 24

Answers

Answer:

D. m= 60, n= 24

Step-by-step explanation:

The angle marked with blue, will also be 2m° (Vertically opposite angles)

So, 2m = (4m- 120)°

2m = 120°

m = 60°

Now, (4m-120)° = 5n° (Vertically opposite angles)

[4(60)- 120]° = 5n°

240- 120 = 5n°

120/5° = n

n= 24°

Use the estimates from (c) and (d) to calculate the relative change in the average household
income from 2002 to 2012. Round to the nearest one percent. Indicate if the change is an
increase or decrease.

Answers

Answer:

it decreased by 5.55% change of 6%

The relative change is -6% Rounding to the nearest percent.

What are average?

The average can be calculated by dividing the sum of observations by the number of observations.

Average = Sum of observations/the number of observations

The relative change can be calculated by dividing the absolute change (the subtraction of the values) by the initial value.

The absolute change is the final value minus the initial value;

Absolute change = 51000 - 54000 = -3000

Now, calculating the relative change;

Relative = -3000/54000

Relative = - 0.0555

Since the relative change is negative, this change indicates a decrease.

Therefore, the relative change is -6% Rounding to the nearest percent.

The parent exponential function of f(x)=2x has been transformed in the following ways:
-a vertical compression by a scale factor of 13
-a vertical translation of 3 units up
-and a horizontal translation of 3 units to the left

Answers

Answer:

The resulting expression is [tex]g(x) = \frac{1}{13}\cdot 2^{x+3}+3[/tex]. We include the graph of both functions, the red line represents the parent exponential function, whereas the blue line is for the resulting function.

Step-by-step explanation:

Statement is incomplete. The question is missing. We infer that question is: What is the resulting expression? Let [tex]f(x) = 2^{x}[/tex], each operation is defined below:

Vertical compression

[tex]g(x) = k\cdot f(x)[/tex], where [tex]0 < k < 1[/tex]. (1)

Vertical translation upwards

[tex]g(x) = f(x) + c[/tex], where [tex]c > 0[/tex]. (2)

Horizontal translation leftwards

[tex]g(x) = f(x+b)[/tex], [tex]b > 0[/tex]. (3)

Now, we proceed to transform the parent exponential function:

(i) A vertical compression by a scale factor of 13 ([tex]k = \frac{1}{13}[/tex])

[tex]f'(x) = \frac{1}{13}\cdot 2^{x}[/tex]

(ii) Vertical translation of 3 units up

[tex]f'' (x) = \frac{1}{13}\cdot 2^{x} + 3[/tex]

(iii) Horizontal translation of 3 units to the left

[tex]g(x) = \frac{1}{13}\cdot 2^{x+3}+3[/tex]

The resulting expression is [tex]g(x) = \frac{1}{13}\cdot 2^{x+3}+3[/tex]. We include the graph of both functions, the red line represents the parent exponential function, whereas the blue line is for the resulting function.

Determine the multiplier in each situation below.

a. A 44% increase

b. A 93% decrease

Answers

Answer:

Step-by-step explanation:

%s can drive a person crazy.

44% increase

Cost = 100% * x + 44%x

Cost = x ( 100 / 100 + 44/100)

Cost = x (1 + 0.44)

Cost = 1.44 x

93% decrease

Cost = 100%x - 93%x

Cost = x * (100/100 - 93/100)

Cost = x * (1 - 0.93

Cost = 0.07 x

Answer:

1.44 and 0.07

Step-by-step explanation:

(a)

A 44% increase of the original amount (100%) is

100 + 44 = 144% = [tex]\frac{144}{100}[/tex] = 1.44 ← multiplier

(b)

A 93% decrease of the original amount (100%) is

100 - 93 = 7% = [tex]\frac{7}{100}[/tex] = 0.07 ← multiplier

Answer:

(4.4, 5.4), (3.2, 8.3), (-7, 15), (23 4/15, 2 7/15)

Step-by-step explanation:

1.

Multiply the first equation by 3/2:

3/2×8x + 3/2×2y = 3/2×46    12x + 3y = 69

Subtract the second equation:

12x - 7x = 69 - 475x = 22x = 4.4

Find y:

4*4.4 + y = 23y = 23 - 17.6y = 5.4

2.

Double the second equation and subtract the first one:

14x - 4x = 94 - 6210x = 32x = 3.2

Find y:

4*3.2 + 6y = 626y = 62 - 12.86y = 49.8y = 8.3

3.

Subtract the second equation from the first one:

4x - 2x = 62 - 762x = -14x = -7

Find y:

4(-7) + 6y = 626y = 62 + 286y = 90y = 15

4.

Multiply the second equation by 4 and subtract the first one:

16y - y = 4(98) - 4315y = 349y = 349/15y = 23 4/15

Find x:

8x + 23 4/15 = 438x = 19 11/15x = 2 7/15
