Answer:

Mean = 8

Variance = 22

Standard deviation = 4.6904

Step-by-step explanation:

To find out Mean the formula is : total sum of data set / number of values

(11 + 11 + 3 + 1 + 11 + 11) / 6 = 48 / 6 = 8

Mean = 8

Now for variance we will form a table

x 11 11 3 1 11 11

(x - Mean) 3 3 -5 -7 3 3

(x - Mean)² 9 9 25 49 9 9

Now we the formula of variance =

Variance = (9+9+25+49+9+9)/(6-1) = 110/5 = 22

Variance = 22

Now we know Standard deviation = √(variance)

Therefore standard deviation = √22 = 4.6904

Find the volume of a rectangular pyramid with length 11 m, width 7 m, and height 8 m. Round to the nearest tenth, if necessary.

madam [21]

Answer:

205.3m

$v = w \times l \times h \div 3$

$v = 11 \times 7 \times 8 \div 3 =$

$v = 77 \times 8 \div 3 =$

$v = 616 \div 3 =$

$v = 205.3333333$

*Round to nearest tenth and 205.3333333 becomes 205.3

Romashka [77]

Regarding conditional probabilities, the keyword is always given, as a previous event is considered to have happened.

<h3>What is Conditional Probability?</h3>

Conditional probability is the probability of one event happening, considering a previous event. The formula is:

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which:

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

The previous event having happened is represented by keyword given.

Consider the sequence 7, 3, −1, −5,−9, … .

Pepsi [2]

Answer:

$a_n=\,\boxed{11-4n}$

Step-by-step explanation:

The sequence has a common difference of 3-7 = -4 and a first term of 7. Using the explicit formula ...

an = a1 +d(n -1)

we can fill in those values to find ...

an = 7 -4(n -1)

an = 11 -4n
