It is like a ratio: the specific number of something over the total of everything. Say you have twenty colors, divided into red, purple, yellow, and green. There are five of each. The likelihood of picking red from all twenty is 4:16. It is the same for the rest. The number of something specific compared the to the total. If there is an uneven amount of something like four and six out of ten, the odds are different and there is a better chance that the six will be over the four.

The odds against each other in the picture is 5:15 because they are basically competing to be picked. The second number wouldn't be twenty because you aren't looking for the total but the likelihood something will be picked over another.

It has been a long time since I have done odds so be sure to ask about it.

If f (x)=3-2x and g (x)=1/x+5 what is the value of f/g (8)

makvit [3.9K]

F(x) = 3 - 2x
g(x) = 1/(x + 5)

(f/g)(x) = (3 - 2x) / 1/(x + 5) = (3 - 2x)(x + 5)
(f/g)(8) = (3 - 2(8))(8 + 5) = -13 x 13 = -169

Find the area of each shape, please help and I will give a lot points

Alex73 [517]

Answer:

15. Area of parallelogram = bh

b = 9m

h = 4m

a = 9*4 = 36m^2

You can also use the rectangle property here.

a = l*b

l = 9

b = 6

a = 9*6 = 54 m^2

Though I would prefer the first one better.

16. Area of triangle = 1/2*bh

b = 17m

h = 3

a = 17*3/2 = 51/2 = 25.5m^2

18. Area of a trapezium = a+b/2*h (a and b are two parallel sides and h the height)

a = 15

b = 7

h = 15

a = 15+7/2*15 = 22/2*15 = 11*15 = 165m^2

19. Area of triangle = 1/2*bh

b = 24

h = 7

a = 24*7/2 = 168/2 = 84

Hope u understood

over 5 days 8,208 people visited the amusement park about how people visited the park per day using rates

Nadusha1986 [10]

Number of people visited per day = Number of People visited / Number of days

= 8208 People / 5 days

= 1641.6 People / day.

Draw an example of a composite figure that has a volume between 750 cubic inches and 900 cubic inches

grigory [225]

Volume:

$V \approx 888.02in^3 \\ \\ And, \ 750in^3$

<h2>Explanation:</h2>

A composite figure is formed by two or more basic figures or shapes. In this problem, we have a composite figure formed by a cylinder and a hemisphere as shown in the figure below, so the volume of this shape as a whole is the sum of the volume of the cylinder and the hemisphere:

$V_{total}=V_{cylinder}+V_{hemisphere} \\ \\ \\ V_{total}=V \\ \\ V_{cylinder}=V_{c} \\ \\ V_{hemisphere}=V_{h}$
