Answer:

f(1)=-11

f(n)=f(n-1)+22

Step-by-step explanation:

Base equation:

f(n)=-11+22(n-1)

f(1)=-11+22(1-1)

f(1)=-11+0

f(1)=-11

f(n)=-33+22n

f(n-1)=-11+22(n-2)

f(n-1)=-55+22n

-33+22n=-55+22n+x

22n gets canceled out

-33=-55+x

-33+55=x

x=22

f(n)=f(n-1)+22

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

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

$Pr = 0.66$

the half-life of isotope X is 2.0 years. How many years would it take for a 4.0mg sample of X to decay and have only 0.50 mg of

shepuryov [24]

After 2.0 years, the 4.0 mg sample decays to 2.0 mg.

After another 2.0 years (total 4.0 years), the 2.0 mg sample decays to 1.0 mg.

And after another 2.0 years (total 6.0 years), the 1.0 mg sample decays to 0.50 mg.

So it takes 6.0 years for 4.0 mg to decay to 0.50 mg.
