Find the mean of the following group of numbers: 1.2, 2.3, 0.8, 2.3, 1.0, 3.1,

Ivenika [448]

Answer:

1.93

Step-by-step explanation:

1.To find the mean you need to add all the numbers

2. Next divide by how many numbers they are

Example:

1,2,3,4

1. Add the numbers together

(1+2+3+4=10)

2. Divide by how many numbers they are

(There are only 4 numbers)

So..... 10 ÷4 =2.5

So 2.5 is the mean

To avoid detection at customs, a traveler has placed 6 narcotic tablets in an Urn containing 9 vitamin pills that are similar in

Alexus [3.1K]

Answer:

$\frac{4}{91}$

Step-by-step explanation:

We are told that to avoid detection at customs, a traveler has placed 6 narcotic tablets in an Urn containing 9 vitamin pills that are similar in appearance.

To find the probability that the traveler will be arrested for illegal possession of narcotics we will use theoretical probability formula.

$\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Number of possible outcomes}}$

Favorable outcomes will be $_{3}^{6}\textrm{C}$ .

$\text{Favorable outcomes}=_{3}^{6}\textrm{C}=\frac{6!}{(6-3)!3!}$

$\text{Favorable outcomes}=\frac{6!}{3!3!}$

$\text{Favorable outcomes}=\frac{6\cdot 5\cdot 4\cdot3!}{3\cdot 2\cdot 1\cdot3!}$

$\text{Favorable outcomes}=\frac{6\cdot 5\cdot 4}{3\cdot 2}$

$\text{Favorable outcomes}=5\cdot 4=20$

Now let us find number of possible outcomes.

$\text{Number of possible outcomes}=_{3}^{15}\textrm{C}=\frac{15!}{(15-3)!3!}$

$\text{Number of possible outcomes}=\frac{15!}{12!3!}$

$\text{Number of possible outcomes}=\frac{15\cdot 14\cdot 13\cdot 12!}{12!\cdot 3\cdot 2\cdot 1}$

$\text{Number of possible outcomes}=\frac{15\cdot 14\cdot 13}{ 3\cdot 2\cdot 1}$

$\text{Number of possible outcomes}=5\cdot 7\cdot 13=455$

Upon substituting our values in probability formula we will get,

$\text{Probability that the traveler will be arrested for illegal possession of narcotics}=\frac{20}{455}$

Upon dividing numerator and denominator by 5 we will get,

$\text{Probability that the traveler will be arrested for illegal possession of narcotics}=\frac{4}{91}$

Therefore, the probability that the traveler will be arrested for illegal possession of narcotics is $\frac{4}{91}$ .

Unit 6, Lesson 15

I am Lyosha [343]

Based on the calculations, we can predict that 2, 3, 4, 5, etc., will make the inequality true.

<h3>How to solve an inequality?</h3>

In Mathematics, an inequality can be used to show the relationship between two (2) or more integers and variables in an equation.

Evaluating the given inequality, we have:

-1 ≤ x/2

-2 ≤ x

x ≥ 2.

Therefore, we can predict that 2, 3, 4, 5, etc., will make the inequality true.

Next, we would complete the table to check our prediction:

x -4 -3 -2 -1 0 1 2 3 4

x/2 -2 -1.5 -1 -0.5 0 0.5 1 1.5 2

When x = -2:

-1 ≤ -2 (false)

When x = 2:

-1 ≤ 1 (true)

When x = 3:

-1 ≤ 3 (true)

When x = 4:

-1 ≤ 4 (true)

Select the correct answer. If , which statement is true? if g(x) = f(1/3x)

sergey [27]

Answer:

B. The graph of function f is stretched horizontally by a scale factor of 3 to create the graph of function g.

Step-by-step explanation:

The rules for linear transformations are that

g(x) = a·f(b·(x-c)) +d

stretches the graph vertically by a factor of "a" (before the shift)

compresses the graph horizontally by a factor of "b" (before the shift)

shifts it to the right by amount "c"

shifts it up by amount "d".

Your equation has b=1/3, so the graph is compressed by a factor of 1/3, which is equivalent to a stretch by a factor of 3.

The appropriate choice of description is ...

b) the graph of g(x) is horizontally stretched by a factor of 3
