A(n) = - 4+ (n - 1)(6)

Mathematics
1 answer:
zmey [24]4 years ago

Answer:

answers in steps

Step-by-step explanation:

if A(n) = - 4+ (n - 1)(6) means A(n) = - 4+ (n - 1) x 6

A(3) = - 4+ (3 - 1) x 6 = 8

A(4) = - 4+ (4 - 1) x 6 = 14

A(11) = - 4+ (11 - 1) x 6 = 56

if A(n) = - 4+ (n - 1)(6) means A(n) = - 4+ (n - 1)⁶

A(3) = - 4+ (3 - 1)⁶ = - 4 + 64 = 60

A(4) = - 4+ (4 - 1)⁶ = - 4 + 6561 = 6557

A(11) = - 4+ (11 - 1)⁶ = - 4 + 1000000 = 999996

How many permutations of three items can be selected from a group of six? Use the letters A, B, C, D, E, and F to identify the i
pishuonlain [190]

Answer:

In total, 120 permutations of three items can be selected from a group of six distinct elements.

In particular, there are 6 ways to order three distinct items.

\begin{aligned}\rm B-D-F \\ \rm B-F-D \\ \rm D-B-F \\ \rm D-F-B \\ \rm F-B-D \\ \rm F-D-B\end{aligned}.

Step-by-step explanation:

The formula \displaystyle P(n,\, r) = \frac{n!}{(n - r)!} = n \, (n - 1) \cdots (n - r + 1) gives the number of ways to select and order r items from a group of n distinct elements.

To select and order three items from a group six distinct elements, let n = 6 and r = 3. Apply the formula:

\begin{aligned} P(6,\, 3) &= \frac{6!}{(6 - 3)!} = \frac{6!}{3!} \\ &= \frac{6 \times 5 \times 4 \times 3\times 2 \times 1}{3 \times 2 \times 1} \\ &= 6 \times 5 \times 4 = 120 \end{aligned}.

In other words, there are 120 unique ways to select and order three items (select a permutation of three items) from a group of six distinct elements.

Consider: what's the number of ways to order three distinct items? That's the same as asking: how many ways are there to select and order three items from a group of three distinct elements? Let n =3 and r = 3. Apply the formula for permutation:

\begin{aligned} P(3,\, 3) &= \frac{3!}{(3 - 3)!} = \frac{3!}{0!} && \left(\text{$0! = 1$ by convention.}\right) \\ &= 3! = 3 \times 2\times 1 \\ &= 6\end{aligned}.

To find the permutations, start by selecting one element as the first of the list. A tree diagram might be helpful. Refer to the attachment for an example.

In each equation below, the letter x stands for an unkn
Sergeeva-Olga [200]

Answer:

x=35

Step-by-step explanation:

Given the following question:

\frac{x}{5} =7

When x is the numerator of the fraction you multiply each side by the denominator in order to isolate the variable.

\frac{x}{5} =7
\frac{5x}{5} =x
7\times5=35
x=35

Hope this helps.

Please help asap i will mark branlist

D.

By looking at the scatterplot, we can identify the ‘trend’, or the general outline of the dots and where they’ll be. Using this, we can predict where a given dot will be in the sequence.

Since the dot for 3 chapters is at 80(roughly) and the dot for 5 chapters is at 140(at the lowest), we can infer that the dot for four chapters will be somewhere in the range of 81-139. From there, we can rule out 140 and 150 as answers, and we can use an inference to pick 120 as the answer.

Hope this helps! :)
