Answer:

725.7 m²

Step-by-step explanation:

A=2πrh

r=16 1/2 ÷ 2 = 8 1/4

A= 2π(8.25)(14)=725.7

Answer:

[tex] \frac{9}{w} = \frac{15}{5} \\ w = 45 \div 15 = 3[/tex]

Answer:

one board game cost 15 dollars

75/5=15

15y

y = number of board games and 15= the price of each board game

so to calculate any number of board games bought just input the number of board games bought for y in the expression 15y and you will get the price.

Answer: Reflection about x-axis

Step-by-step explanation:

Given

Initially, vertices are [tex]A(-2,0), B(2,5),C(3,1)[/tex]

After reflection they become [tex]A(-2,0),B(2,-5),C(3,-1)[/tex]

It is clear that the x coordinate remains unchanged and the y coordinate changes its sign. It occurs when reflection is done about the x-axis.

For example, when (a,b) is reflected about the x-axis, it becomes (a,-b).

So, here reflection is being done about the x-axis.

Answer:

(-3, -2)

Step-by-step explanation:

To find the solution of two functions, you need to know at which x and y value they are equal. So solve for x and y when 1/3x - 1 = 2x + 4

1/3x - 1 = 2x + 4

First, subtract 2x from both sides.

-5/3x - 1 = 4

Add one to both sides.

-5/3x = 5

Multiply both sides by the reciprocal of -5/3 (3/-5)

x = -3

Then, substitute x into one of the equations to get y.

1/3(-3) - 1

-1 - 1 = -2

So drag the dot to the point (-3, -2)

Answer:

Median = 10

Mean = 18

Step-by-step explanation:

1) Median equals the middle number of a set.

To find median, place the numbers from least to greatest. So that’ll turn to be:

0, 8, 9, 10, 26, 35, 38

The middle number is 10.

2) Mean is the average of all the numbers.

To find mean, add all the numbers together. So 0+8+9+10+26+35+38 = 126

Then, divide the sum by the amount of numbers you added. We added a total of 7 numbers to get 126. 126/7 = 18. The average is 18.

Answer:

The median is 10 and the mean is 18 . Hope it help

Step-by-step explanation:

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest

Answer:

The Mean 14.5 and the Median is 15

Step-by-step explanation:

For the Mean you just add all the numbers up and divide on how many you have. And the Median the middle

Answer:

Below in bold.

Step-by-step explanation:

First arrange in ascending order:

5 8 9 11 13 15 16 17 17 18 22 23

Median = mean of the middle 2 values = (15+16)/2 = 15.5.

Mean = Sum of all the values / 12 = 174/12 = 14.5.

Interquartile range =  upper quartile - lower quartile = 17 - 11 = 6.

Answer:

The sample space of a random experiment is the collection of all possible outcomes. An event associated with a random experiment is a subset of the sample space. The probability of any outcome is a number between 0 and 1.

Answer:

27

Step-by-step explanation:

Boys to girls is 2:3

and there are 18 boys so that means the 2 in 2:3 is actually 18

and 2 x 9 = 18 , so you would need to also multiply 3 by 9.

3 x 9 = 27

18:27

there are 27 girls

Answer:

It is a permutation problem. There are 2193360 possibilities of selecting 4 candidates from 40 applicants when order of selection is considered.

Step-by-step explanation:

In this case, the company will hire four different applicants from a group of 40 people for 4 different jobs. In this case, we need to consider the effect of order in the number of possibilities. Hence, we must use the permutation formula:

[tex]_{n} P_{k} = \frac{n!}{(n-k)!}[/tex] (1)

Where:

[tex]n[/tex] - Total of applicants.

[tex]k[/tex] - Selected applicants.

If we know that [tex]n = 40[/tex] and [tex]k = 4[/tex], then the number of possibilities is:

[tex]_{40}P_{4} = \frac{40!}{(40-4)!}[/tex]

[tex]_{40}P_{4} = 40\times 39 \times 38 \times 37[/tex]

[tex]_{40}P_{4} = 2193360[/tex]

There are 2193360 possibilities of selecting 4 candidates from 40 applicants when order of selection is considered.

Given:

Sum of ages of brother and sister = 15

Product of their ages = 54

To find:

How old is the older one between the two of them?

Solution:

Let x be the age of brother and y be the age of sister.

Sum of ages of brother and sister = 15

[tex]x+y=15[/tex]

[tex]x=15-y[/tex]                ...(i)

Product of their ages = 54

[tex]xy=54[/tex]

[tex](15-y)y=54[/tex]                [Using (i)]

[tex]15y-y^2=54[/tex]

[tex]0=54-15y+y^2[/tex]

Splitting the middle term, we get

[tex]54-15y+y^2=0[/tex]

[tex]54-9y-6y+y^2=0[/tex]

[tex]9(6-y)-y(6-y)=0[/tex]

[tex](6-y)(9-y)=0[/tex]

Using zero product property, we get

[tex](6-y)=0\text{ and }(9-y)=0[/tex]

[tex]y=6\text{ and }y=9[/tex]

If [tex]y=6[/tex], then using (i), we get

[tex]x=15-6[/tex]

[tex]x=9[/tex]

If [tex]y=9[/tex], then using (i), we get

[tex]x=15-9[/tex]

[tex]x=6[/tex]

Therefore, the age of older one is 9, the age of younger one is 6 and the difference between their ages is 3.

Answer:

Volume of the cooler = 2,772 in³

Step-by-step explanation:

Volume of the cooler = length × width × height

Length = 22 in

Width = 12 in

Height = 10 1/2 in

= 21/2

= 10.5 in

Volume of the cooler = length × width × height

= 22 in × 12 in × 10.5 in

= 2,772 in³

Volume of the cooler = 2,772 in³
