How many ways can you order 8 speakers for a conference?

Answer:

A ∝ BCD or A = kBCD (k = constant ), then A varies jointly as B, C and D.

Step-by-step explanation:

The value of 'w' when x = 4 and y = 3 is, 40.

In its most basic form, a ratio is a comparison between two comparable quantities.

There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.

If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.

Given, The value of w varies jointly with x and y.

Let, w ∝ xy ⇒ w = kxy.

5 = k×(3/4)×2.

5 = (3/2)k.

k = 10/3.

Now, x = 4 and y = 3.

Therefore,

w = (10/3)×4×3.

w = 40.

Step-by-step explanation:

Answer: x < 4

Step-by-step explanation: To plot an inequality, find the number and go the way the sign is pointing.

In this problem...

The less than sign is pointing left, and the number is 4. We use an open circle because the sign is not equal to. If it was, we would of put a closed circle.

<, or > = Open circle (Not shaded)

≤, or ≥ = Closed circle (Shaded)

Answer:

if it increases 8% each year, the next year it's not 8% of the original, but 8% of the 108% and so forth.

The increase after 10 years is (108%)^10 - 100% which is bigger than 80%.

If the value of a stock increases by 8% each year, then, that is not equal to the value of a stock increases 80% each decade.

The degree to which a value increases expressed in percent form is known as percentage increase.

Given that, The value of a stock increases by 8% each year.

a) If it increases 8% each year, the next year it's not 8% of the original, but 8% of the 108% and so forth, the incasement in percentage is an exponential increase not a linear increase, so we can't say that, the value of the stock increases 80% each decade

b) Since,  (108%)¹⁰ > 80%

Hence, the increase after 10 years is (108%)¹⁰, will be bigger than 80%.

Hence, If the value of a stock increases by 8% each year then, that is not equal to the value of a stock increases 80% each decade

Answer:

1005.3 ft³

Step-by-step explanation:

cylinder has a base diameter of 8ft and a height of 20ft. What is it's volume in cubic ft, to the nearest 10th place?

Given that:

Base diameter = 8feets

Radius, r = 8/2 = 4 feets

Height h, = 20 feets

Volume of cylinder, V = πr²h

V = π * 4² * 20

V = π * 16 * 20

V = 1005.3096

V = 1005.3096 ft³

Step-by-step explanation:

In essence, it represents the sum of all comments divided by the number of responses.

It implies scoring in the five games corresponds to a total of five results.

Scores :

7 points implies+ 7 

lost by 3 implies- 3 

lost by 2 implies - 2

won by 4 implies + 4 

won by 9 implies + 9 

Sum of all scores [tex]= 7 - 3 - 2 + 4 + 9 = 15[/tex]therefore

Its team has a total of 5 games[tex]= 5[/tex]

Measurement in scores in five games thus = sum of all scores/sum with the team played games [tex]=\frac{15}{5}= 3[/tex]
