Answers

Answer 1

Answer:

11.67

Step-by-step explanation:

16+8+15+5+6+20=70

70 divided by 6= 11.666666666667

11.666666666667= 11.67

Answer 2

Answer:

11.666666667 - rounded would be  11.67

Take away the 6 or 7. Can't remember

Step-by-step explanation:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

4. Nguyen is decorating the room for her sister's baby shower party. She is wrapping
Vietnamese conical hats in baby prints tissue paper to decorate the tables and some
shelves in the wall. Each hat has a diameter of 16 inches and a height of 9 inches. If
she wants to wrap 21 Vietnamese hats, how much tissue paper will she need?
A 4,176 in2
B 8,975 in2
C 10,580 in2
D 36,267 in 2

Answers

Answer:

Step-by-step explanation:

Given the information of the conical hat

diameter of 16 inches => Radius = 8 inches height of 9 inches

=> the slant height of the hat is (use Pythagorean Theorem)

[tex]s^{2}[/tex] = [tex]r^{2} + h^{2}[/tex]

<=> [tex]s^{2}[/tex] = [tex]8^{2} + 9^{2}[/tex]

<=> s = [tex]\sqrt{145}[/tex]  

The area (without the base area) of tissue paper will she need to make one hat is:

SA = πrs  in2

<=> SA =  π*8*[tex]\sqrt{145}[/tex]  in2

<=> SA =8 [tex]\sqrt{145}[/tex] π

=> the total tissue paper will she need for 21 hats is:

SA*21

= 8 [tex]\sqrt{145}[/tex] π*21

= 6352,18 in 2

The units pf the digits of a two digits numeral is 8 if the digits are reversed the new number is 18 greater than the oringal number fund the oringal numeral

Answers

complete question:

The sum of the digits of a two-digit numeral is 8. If the digits are reversed, the new number is 18 greater than the original number. How do you find the original numeral?

Answer:

The original number is 10a + b  = 10 × 3 + 5  = 35

Step-by-step explanation:

Let

the number = ab

a occupies the tens place while b occupies the unit place. Therefore,

10a + b

The sum of the digits of two-digits numeral

a + b = 8..........(i)

If the digits are reversed. The reverse digit will be 10b + a. The new number is 18 greater than the original number.

Therefore,

10b + a = 18 + 10a + b

10b - b + a - 10a = 18

9b - 9a = 18

divide both sides by 9

b - a = 2...............(ii)

a + b = 8..........(i)

b - a = 2...............(ii)

b = 2 + a from equation (ii)

Insert the value of b in equation (i)

a + (2 + a) = 8

2a + 2 = 8

2a = 6

a = 6/2

a = 3

Insert the value of a in equation(ii)

b - 3 = 2

b = 2 + 3

b = 5

The original number is 10a + b  = 10 × 3 + 5  = 35

A block's volume is found by multiplying the length, width and height. We have 5*5*5 = 125 as the volume. The units are in cubic centimeters which you can write as "cubic cm" or "cc" for short. Another way to write it is as "cm^3"

Side note: Your math book or your teacher may refer to a block as a rectangular prism.

Step-by-step explanation:

the formula for V  of a cube is length x width x height. so you will go 5cm x 5cm x 5cm =125cm^3

What is \text{P(not }3)P(not 3)start text, P, left parenthesis, n, o, t, space, end text, 3, right parenthesis? If necessary, round your answer to 222 decimal places.

Answers

Answer:

There is no enough information to determine probability of not having 3, P(not 3).

Suppose we were given the probability of having 3, P(3), we can easily find P(not 3).

The probability of success plus the probability of failure of an event is always equal to 1.

If p is the probation success, and q, of failure, then p + q = 1

So,

P(3) + P(not 3) = 1

That is

P(not 3) = 1 - P(3).

Solve for g.

8g + 3 = –6g + 13g + 13

Answers

Answer: g = 10

Step-by-step explanation: 8g + 3 = –6g + 13g + 13

                                             8g + 3 = (–6g + 13g) + (13)

                                             8g + 3 = 7g + 13

                                             8g + 3 - 7g = 7g + 13 - 7g

                                             g + 3 = 13

                                             g + 3 - 3 = 13 - 3

Answer:

[tex]8g + 3 = -6g + 13g + 13 : g = 10[/tex]

Step-by-step explanation:

[tex]8g+3=-6g+13g+13[/tex]

[tex]8g+3=7g+13[/tex]

75% of the temperatures are below what value? How do you know? 75% of the temperatures are above what value? How do you know? What conclusions can you draw about the temperature in Maryland?

Answers

Answer:

Complete Question:

Pick a city in Maryland and determine the average high temperatures for each month. Record this in a table.

a. Create a box-and-whisker plot for the data.

b. What is the median temperature?

c. 75%of the temperatures are below what value?How  do you know? d. 75% of the temperatures are above what value? How do you know? e. What conclusions can you draw about the temperature in Maryland?

Step-by-step explanation:

TASK 3

The city picked is Baltimore, the year 2017.

The table is attached in picture #1.

a) The box-and-whisker plot is attached in picture #2.

b) The median is the central value of the distribution i.e:  

42.4, 45.3, 46.8 | 54.7, 57.6, 66.0 | 69.1,  76.5,  80.6 | 85.8, 87.8, 90.0 

where we marked with a tally the quartiles.

As we have 12 values,  the average between the two central values will be the median :

M = (66.0 + 69.1) / 2 = 67.1 °F

c) 75% of the temperatures are below 83.2 °F.

Indeed, this value represents the third quartile. The position of the third quartile can be found by the formula:

3/4 · (n + 1) = 3/4 · (12 + 1) = 3/4 · 13 = 9.75

Therefore, since we did not get in integer position, the third quartile will be the average between the numbers in position 9 and 10:

q₀.₇₅ = (80.6 + 85.8) / 2 = 83.2 °F

d) 75% of the temperatures are above 50.8 °F.

Indeed, this value represents the first quartile. Similarly to point c), the position can be found by the formula:

1/4 · (n + 1) = 1/4 · 13 = 3.25

And therefore:

q₀.₂₅ = (46.8 + 54.7) / 2 = 50.8 °F. 

e) Baltimore in 2017 had a median high temperature of 67.1 °F.

25% of the year the high temperatures were warmer than 83.2 °F, with no outlier above 90.0 °F which was the hottest temperature.

25% of the high temperatures were colder than 50.8 °F, with no outlier below 42.4 °F, which was the coldest high temperature.

Since the company wants to survey 500 customers by the countries visited, the number of samples from each country will be proportional to the number of customers.

For UK, Number of Samples[tex]=\dfrac{968}{4000}X500=121[/tex]

For France, Number of Samples[tex]=\dfrac{248}{4000}X500=31[/tex]

The triangle with a base of 4 and a height of 3 has an area of 6 square meters.

Based on the given information, we have a triangle with a base of 4 and a height of 3.

To calculate the area of the triangle, we use the formula:
Area = (base * height) / 2.

Substituting the values, we have
Area = (4 * 3) / 2    

        = 12 / 2

Step-by-step explanation:

The radius of the flower bed = 1/2 * 22 = 11m

The radius of the whole area included the sidewalk = 11 + 4 = 15 m

So the area of the sidewalk = area of the whole - area of flower bed

= 3.14 * 15^2 - 3.14* 11^2

Two beach rental companies compared their sales from last weekend. Both companies rent out jet skis and kayaks, and they charge the same prices. Will's Watersports made a total of $780 from renting 12 jet skis and 9 kayaks. Family Fun Rentals made a total of $570 from renting 7 jet skis and 11 kayaks. What is the cost of each type of rental?

Answers

Answer:

To rent a jet ski you need to pay $50 and to rent a kayak you need to pay $20

Step-by-step explanation:

Since both shops charge the same amount for each kind of vehicle, we will assign variables to the their cost. The cost of a jet ski will be "x" and the cost of the kayak will be "y". Therefore we can create a system of equations as shown below:

Will's shop:

12*x + 9*y = 780

Fun Rentals:

7*x + 11*y = 570

[tex]\left \{ {{12x+ 9y=780} \atop {7x + 11y =570}} \right.\\[/tex]

We can isolate "x" on the second equation, we have:

[tex]x = \frac{570 - 11y}{7}[/tex]

Applying this value on the first equation:

[tex]12[\frac{570 - 11y}{7}] + 9y = 780\\\frac{6840 - 132y}{7} + 9y = 780\\\frac{6840 - 132y + 63y}{7} = 780\\ 6840 - 132y + 63y = 5460\\6840 - 69y = 5460\\69y = 1380\\y = 20[/tex]

Applying the value of "y" we found on the "x" equation above, we have:[tex]x = \frac{570 - 11*20}{7}\\x = 50\\[/tex]

Therefore to rent a jet ski you need to pay $50 and to rent a kayak you need to pay $20
