given the arithemtic or geometric sequence, identify f(0) and the common difference ratio f(x) = 4-2/3x

ankoles [38]

Answer:

Required value of f(0) = 4 and common difference of given sequence is $\frac{-2}{3}$

Solution:

Given sequence rule for arithmetic sequence is $\mathrm{f}(\mathrm{x})=4-\left(\frac{2}{3}\right) x$

We need to determine f(0) and common difference

Calculating f(0).

Substituting x = 0 in given sequence rule we get

$\begin{array}{l}{f(0)=4-\left(\frac{2}{3}\right) 0} \\ {=4-0=4}\end{array}$

Calculating common difference

Let’s first calculate f(1) and f(2).

Substituting x = 1 in given sequence rule

$\begin{array}{l}{\mathrm{f}(1)=4-\left(\frac{2}{3}\right) 1} \\ {=4-\left(\frac{2}{3}\right)=\frac{10}{3}}\end{array}$

$\mathrm{f}(2)=4-\left(\frac{2}{3}\right) 2=4-\left(\frac{4}{3}\right)=\frac{8}{3}$

Common Difference can be found by subtracting f(1) from f(2)

$\text { Common difference }=\mathrm{f}(2)-\mathrm{f}(1)=\left(\frac{8}{3}\right)-\left(\frac{10}{3}\right)=\frac{-2}{3}$

Hence required value of f(0) = 4 and common difference of given sequence is $\frac{-2}{3}$

Given that the following two geometric series(meetkundige reekse) are covergent 1+x+x²+x³+... And 1-x+x²-x³+... Determine the va

Oksanka [162]

The sets are (1,-1) or (-1,1)

Lets see

Take until 4terms

$\\ \rm\longmapsto S_4=1+1+1^2+1^3=1+1+1+1=4$ (1,-1)

$\\ \rm\longmapsto S_4=1+(-1)+(-1)^2+(-1)^3=1-1+1-1=0$ (-1,1)

$\\ \rm\longmapsto S_4=1-(-1)+(-1)^2-(-1)^3=1+1+1+1=4$ (1,-1)

$\\ \rm\longmapsto S_4=1-1+(1)^2-1^3=1-1+1-1=0$ (-1,1)

Hence verified

Another set can be (0,0)

Proof:-

$\\ \ast\rm\longmapsto S_3=1+0+0^2=1$

$\\ \ast\rm\longmapsto S_3=1-0+0^2=1$

Hence verified.

If we buy 20 pickles what is the experimental probability of winning 5 or more tickets

Mrac [35]

Answer:

$Pr = 0.66$

Step-by-step explanation:

Given

See attachment for complete question

Required

$P(x \ge 5)$

From the attachment, we have:

$S = 2 + 8 + 4+20+21+19+17+5+2+2$

$S =100$ ---- the sample size

Next, we list out all outcomes more than or equal to 5.

i.e.

$x \ge 5$

5 is represented with the vertical blue rectangle (with frequency 21).

So, the other elements are to the right of frequency 21.

So, we have:

$x \ge 5 = 21+19+17+5+2+2$

$x \ge 5 = 66$

The probability is then calculated as:

$Pr = \frac{x \ge 5}{S}$

This gives

$Pr = \frac{66}{100}$

$Pr = 0.66$
