Answer:

9.8.  is the Average Age
30.7 is the Variance

Step-by-step explanation:

9.8 is the Average Age and the 30.7 is the Variance.

The term variance refers to a statistical measurement of the spread between numbers in a data set.

Given that, 4 zebras at a local zoo have ages 14, 15, 9, 1,

We need to find the average age and the variance,

we know that,

Average = Sum of all the values of the set given / Number of values in the set

And,

Variance = sum of all the values of (x - means) ² / (n)

So,

Average age = 14 + 15 + 9 + 1 / 4 = 39/4 = 9.75

Variance =

(14-9.75) ² = 18.06

(15-9.75) ² = 27.56

(9-9.75) ² = 0.5625

(1-9.75) ² = 76.56

= 18.06 + 27.56 + 0.5625 + 76.56 / 4

=  30.68 ≈ 30.7

Hence, 9.8 is the Average Age and the 30.7 is the Variance.

Answer:

18

Step-by-step explanation:

Let's call the first number n. The next four numbers will be n + 3, n + 6, n + 9 and n + 12. Then, we have

n + n + 3 + n + 6 + n + 9 + n + 12 = 105

5n + 30 = 105

5n = 75

n = 15

The second smallest number is n + 3 which is 15 + 3 = 18.

Answer:

(b + 3)(4b + 5)

Step-by-step explanation:

Given

4b² + 17b + 15

Consider the factors of the product of the b² term and the constant term which sum to give the coefficient of the b- term.

product = 4 × 15 = 60 and sum = 17

The factors are 12 and 5

Use these factors to split the b- term

4b² + 12b + 5b + 15 ( factor the first/second and third/fourth terms )

= 4b(b + 3) + 5(b + 3) ← factor out (b + 3) from each term

= (b + 3)(4b + 5) ← in factored form

Answer:

The correct answer is A. {R,G,Y,B}.

Step-by-step explanation:

The sample space for the given information is A. {R, G, Y, B}.

A sample space can be defined as a set of all possible outcomes of a random experiment.

The sample space is represented by the symbol, ‘S’. Sample space can also be expressed using the set notation, {}.

Given that, a bag has 4 balls: 1 red (R), 1 green (G), 1 yellow (Y), and 1 blue (B), we need to find the sample space for this data,

So,

Since, the sample space is the all the data in the set,

Therefore, the whole set is = 1 red (R), 1 green (G), 1 yellow (Y), and 1 blue (B).

Therefore,

S = {R, G, Y, B}

Hence, the sample space for the given information is A. {R, G, Y, B}.

numerator/denominator

Let's analyze the answer choices.

A. 6 2/3

The bottom number of the fraction is a 3, so this cannot be correct.

B. 16/18

The denominator here is 18, so this choice is also incorrect.

C. 6/7

In this fraction the numerator is a 6, but the denominator is a 7, so this choice is also wrong.

Step-by-step explanation:

Answer & Step-by-step explanation:

For this problem, all we have to do is multiply the two expressions.

f(x) = 3x + 1

g(x) = x² - 6

Now, let's set up our equation for multiplication.

(f * g)(x) = (3x + 1)(x² - 6)

(f * g)(x) = 3x³ - 18x + x² - 6

(f * g)(x) = 3x³ + x² - 18x - 6

So, (f * g)(x) is 3x^3 + x^2 - 18x - 6

the correct Answer is

3x^3+x^2-18x-6

-2x-3= 3-x-1

add 3 on both sides

-2x = 6 - x - 1
