An ordinary (fair) die is a cube with the numbers 1 through 6 on the sides (represented by painted spots). Imagine that such a d
Anika [276]

Answers:

P(A) = 7/12

P(B) = 1/4

====================================================

Explanation:

Instead of having one die, let's say we have two dice. I'll make one red and the other blue.

I'll be using the dice chart shown below. The red and blue values add up to the black numbers inside the table. For instance, we have 1+1 = 2 in the upper left corner. There are 6*6 = 36 sums total.

Using that table, we can see the following:

  • There are 6 copies of "7"
  • There are 5 copies of "8"
  • There are 4 copies of "9"
  • There are 3 copies of "10"
  • There are 2 copies of "11"
  • There is 1 copy of "12"

In total, we have 6+5+4+3+2+1 = 21 instances where the two dice add to something larger than 6.

This is out of 36 ways to roll two dice.

Therefore P(A) = 21/36 = (3*7)/(3*12) = 7/12

-----------------------------------

If a number is divisible by 4, then it is a multiple of 4.

The multiples of 4 found in the table are: 4, 8, 12

We have

  • 3 copies of "4"
  • 5 copies of "8"
  • 1 copy of "12"

This gives 1+5+3 = 9 values that are a multiple of 4

P(B) = 9/36 = (1*9)/(4*9) = 1/4

Hal says the volume of the sphere shown below 36 cm3. Find the correct volume, using 3.14 for pi. Round to the nearest hundredth
adelina 88 [10]

Answer:

Volume of sphere is 35.98cm^3

Step-by-step explanation:

It is given that Hal says that volume of sphere is 36cm^3

Volume of sphere is given by V=\frac{4}{3}\pi r^3

\frac{4}{3}\pi r^3=36

\pi r^3=27

r^3=8.594

r=2.048cm

Now using 3.14 in place of \pi

Now volume of sphere is

V=\frac{4}{3}\times 3.14\times 2.048^3

V=35.98cm^3

Therefore volume of sphere when we use 3.14 in place of \pi is 35.98cm^3

And the Hal likely error is he uses \pi directly for calculation of volume.
