Six popular brands of tea are to be used in a blind taste study for consumer recognition. If three distinct brands are chosen from the six, and if the consumer is NOT allowed to repeat any answers, what is the probability that a consumer could identify all three brands correctly just by guessing?

Answers

Answer 1
Answer: it could be 3/6 which means the probability is 1/2
Answer 2
Answer: (1/6)*(1/5)*(1/4)=(1/120)

I'm not sure but i think this is the answer. Do reply if you get it correct.

Which type of function best models the given data?
(1) linear function with a negative rate of change
(2) linear function with a positive rate of change
(3) exponential decay function
(4) exponential growth function

Answers

In this exercise we need to have knowledge about functions in order to identify the function that corresponds to the values ​​informed, like this:

Letter D

When dealing with the growth or decrease of several values, we find the exponential function, which can be described as:

  • exponential function, in mathematics, a relation of the form y = ax, accompanying the liberated variable x ranging over the whole genuine in existence number line as the example of a positive number a. Probably ultimate influential of the rapid change functions happen y = ex, every now and then composed y = exp (x),

On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite direction. The number b varies directly with the number a. For example b = 2 when a = –2. Which equation represents this direct variation between a and b?

Answers

Answer:

The equation is b = -a

Step-by-step explanation:

Given,

The number b varies directly with the number a,

That is, we can write,

b ∝ a

⇒ b = ka

Where k is the constant of proportionality,

Given, if b = 2 then a = -2,

By substituting the value,

2 = k(-2)

⇒ k = -1

Hence, the equation that represents the direct variation between a and b is,

b = -a
y=kx is the equation for direct variation

The sum of the interior angles of any regular polygon is (n - 2) X 180
30 = n
[(30) - 2] × 180
28 X 180
5040

The interior angle of a regular polygon = the sum of interior angles ÷ number of sides
5040 ÷ 30 = 168

Therefore the measure of each interior angle in a regular 30-sided polygon is 168°

9 is added to the product of 9 and a number

"a number," which is unknown will be represented by "x."

The predicted of 9 and x is 9x.

9 added is +9.

So the expression is 9x + 9
