If B+2(a+1)=c then a+1

2 answers:

5 0

If b+2(a+1) = c, find the value of a+1

Subtract b from both sides: b+2(a+1) - b = c - b
2(a+1) = c - b
Divide both sides by 2:
a+1 = (c - b) /2

B+2(a+1)=c
2(a+1)=c-B
a+1=(c-B)/2
Its pretty simple process actually

Suppose that two teams are playing a series of games, each of which is independently won by team A with probability p and by tea

Lady_Fox [76]

Answer:

4 games played = 1/56

5 games played = 5/56

6 games played = 15/56

7 games played = 35/56

Step-by-step explanation:

The probability of each time winning is 0.5

So there are a couple of ways the series could go.

Team A could win all first 4 matches. We can depict this as A-A-A-A
Team A could win 4, while having lost 1. Lets depict this a A-B-A-A-A
Team A could win 4, while having lost 2. A-B-B-A-A-A
Team A could win 4, while having lost 3. A-B-B-B-A-A-A

These 4 possibilities could be repeated with B winning as well. It should be noted that these are the only ways for the series to end. We find the number of permutations of each possibility above to find their probability.

I advise you to study 'how to permute identical objects' for this.

These permutations are stated below:

1. 4!/4! = 1

2. $\frac{5!}{4! * 1!}$ = 5

3 $\frac{6!}{4! * 2!}$ = 15

4 $\frac{7!}{4! * 3!}$ = 35

These are they ways A or B could win. The total is 1+5+15+35 = 56. The answer given thus reflects the possibilities.

Find the volume of the following solid. Using cylindrical coordinates

Reika [66]

In cylindrical coordinates, the equations of the surfaces become

$z = 4 - 4r^2 \\\\ z = (r^2)^2 - 1 = r^4 - 1$

These surfaces intersect on the cylinder of radius 1 with cross sections parallel to the x,y-plane:

$4 - 4r^2 = r^4 - 1 \\\\ \implies r^4 + 4r^2 - 5 = (r-1)(r+1)(r^2+5) = 0 \\\\ \implies r=1$

Then in cylindrical coordinates, the volume of the space bounded by these surfaces is

$\displaystyle \int_0^{2\pi}\int_0^1\int_{r^4-1}^{4-4r^2}r\,\mathrm dz\,\mathrm dr\,\mathrm d\theta = 2\pi \int_0^1 \int_{r^4 - 1}^{4-4r^2}r\,\mathrm dz\,\mathrm dr \\\\ = \pi \int_0^1 (4-4r^2)^2 - (r^4-1)^2 \,\mathrm dr \\\\ = \pi \int_0^1 (15-32r^2+18r^4-r^8)\,\mathrm dr = \boxed{\frac{352\pi}{45}}$

Gina saves quarters. She has $17.75 in quarters. How many quarters does she have? Show your solution in two ways. Use division t

Bad White [126]

Gina wants to know how many quarters she has if she has seventeen dollars and seventy-five (17.75)cents in all quarters. To find he number of quarters, you need to divid seventeen dollars and seventy-five cents (17.75) by twenty five cents (0.25) to get her answer.

17.75/0.25=71
