Answer:

The mode of the data sets

Step-by-step explanation:

The measure of central tendency is a value that aims to give the description of a data set by providing a pointer to the central position of the data set

The item under comparison = The most common women running shoe color and the most common women sandal color

The characteristics of the items under comparison = Color (nominal characteristic)

Therefore, the measure of central tendency will aim to show the frequency with which particular colors are worn, which is represented by the mode of the data set

Answer:

[tex]b(b+7)(b-7)[/tex]

Step-by-step explanation:

Start by factoring a [tex]b[/tex] out:

[tex]b(b^2-49b)[/tex]

For the term [tex]b^2-49b[/tex], we're looking for two numbers that add up to 0 and multiply to be -49:

[tex]7+(-7)=0,\\7\cdot -7=-49\\[/tex]

Two numbers: [tex]7\text{ and }-7[/tex]

Therefore, we have:

Answer:

circumference of a circle=πd where d is the diameter of the circle.

this implies, the circumference=3.14*10cm

=31.4cm

Answer:

c = 13

Step-by-step explanation:

1. Pythagorean theorem states that c^2 = a^2 + b^2

2. In this case, a = 5, b = 12. Therefore, the equation is:

c^2 = 5^2 + 12^2

3. c^2 = 25+144 = 169

4. square root both sides

5. c = 13, c = -13

6. c = 13 since a length cannot be negative.

7. Final answer: C = 13

Answer:

but where is the diagram

Elena drops her pencil into her cup and notices that it just fits diagonally. The pencil is 17 cm long and the cup is 15 cm tall. The diameter of the cup is 8 cm.

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

Elena drops her pencil into her cup and notices that it just fits diagonally. The pencil is 17 cm long and the cup is 15 cm tall.

Consider the pencil and cup just make a right angle triangle. If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2 \\\\|17|^2 = |15|^2 + |BC|^2 \\\\289 = 225 + |BC|^2 \\\\ |BC|^2 = 289 - 225\\\\ |BC|^2 = 64\\\\ |BC|^2 = \sqrt{64} \\\\BC = 8[/tex]

Answer:

43

Step-by-step explanation:

Inscribed Angle = 1/2 Intercepted Arc

< MQP = 1/2 ( 86)

< MQP = 43

Answer:

43°

Step-by-step explanation:

The measure of an inscribed angle is half the measure of the arc it subtends.

m<Q = (1/2)m(arc)MP

m<Q = 1/2 * 86°

m<Q = 43°

Answer:

10 pizzas

Step-by-step explanation:

Jaxson is throwing a pizza party. He has 1\tfrac{1}{4}1 4 1 ​ pounds of cheese available and he needs \tfrac{1}{8} 8 1 ​ pound of cheese to make each pizza. How many pizzas can he make?

We can interprete the above question as:

1/8 pounds of cheese = 1 pizza

1 1/4 pounds of cheese = x pizzas

Cross Multiply

1/8 × x = 1 1/4 × 1

x = 1 1/4 ÷ 1/8

x = 5/4 ÷ 1/8

x = 5/4 × 8/1

x = 10 pizzas

x = 10 pizzas

Answer: $16.80

Step-by-step explanation:

The disinfecting wipes cost $12 for the store to buy one.

They then add a 40% mark up.

Find out what 40% of $12 is:

= 40% * 12

= $4.80

Add the markup to the cost to find the selling price:

= 12 + 4.80

= $16.80

Area of equilateral triangle = 81√3 cm²

Step-by-step explanation:

Given:

Perimeter of an equilateral triangle = 54 cm

Find:

Area of equilateral triangle

Computation:

Perimeter of an equilateral triangle = 3 x Side

54 = 3 x Side

Side of equilateral triangle = 54 / 3

Side of equilateral triangle = 18 cm

Area of equilateral triangle = [√3/4]side²

Area of equilateral triangle = [√3/4][18]²

Area of equilateral triangle = [√3/4][324]

Area of equilateral triangle = [√3][81]

Area of equilateral triangle = 81√3 cm²

Answer:

x = 20

y = 20√2  

Step-by-step explanation:

This is a 45 - 45 - 90° special right triangle

In a 45 - 45 - 90° triangle the legs are congruent and the hypotenuse = leg * √2

If one leg = 20 then the other leg also = 20

Thus, x = 20

If leg = 20

Then hypotenuse = 20 * √2 or 20√2

Thus, y = 20√2  

Answer:

The length of string = 32.35 meter (Approx.)

Step-by-step explanation:

Given:

Vertical height of kite = 22 meter

Angle with horizontal = 43°

Find:

The length of string

Computation:

Using trigonometry function;

Vertical height of kite [Perpendicular]  = 22 meter

The length of string[Hypotenuse]

Sin θ = Perpendicular / Hypotenuse

Sin 43 = 22 / Hypotenuse

0.68 = 22 / Hypotenuse

Hypotenuse = 22 / 0.68

Hypotenuse = 32.35 meter

The length of string = 32.35 meter (Approx.)

Answer:

Ethan cycles from home for x km at 9km/h to the MRT station.

He waited for 3 mins before catching the next MRT train.

The MRT train travels at an average speed of 60km/h.

He walks for 1/2km at an average speed of 6km/h before reaching his school.

The distance from his home to the school by the above route is 12km and the total time he spent is 28 mins.

:

(i) Express, in terms of x, the time he spent cycling from home to the MRT station.

time = dist/speed

f(x) = x%2F9

:

(ii) Find the distance travelled by Ethan when he was travelling to school using the MRT

dist by train

d = 12 - x - .5

d = 11.5 - x

(iii) Form an equation in x and solve it.

Subtract the 3 min of waiting, change to hrs: 25/60 = 5%2F12

Write a time equation

bike time + train time + walk time = 5/12 hrs

x%2F9 + %28%2811.5-x%29%29%2F60 + .5%2F6 = 5%2F12

multiply by 180, resulting in

20x + 3(11.5-x) + 30(.5) = 15(5)

20x + 34.5 - 3x + 15 = 75

20x - 3x + 49.5 = 75

17x = 75 - 49.5

17x = 25.5

x = 25.5/17

x = 1.5 km by bike

You can confirm this yourself, find the time of each stage of the trip and

the total should be 5/12 hrs which .4167 hrs on a calc
