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

Carbon-14 has a half-life of 5730 years. In a plant fossil, you find that the 14C has decayed to 1/8.00 of the original amount.
drek231 [11]
Note that 8.00 = (2.00)^3, that implies that a decay to 1/8.00 means that the Carbon-14 has passed 3 half-life. (1 to decay to 1/2, other to decay to 1/4, and other to decay to 1/8). And, three half-life is 3 * 5730 years = 17,920 years. So,<span> the answer is that the plant was alive 17,920 years.</span>

Divide and simplify 4/7÷(-11/2)​
lys-0071 [83]

Answer: -\frac{8}{77}

Step-by-step explanation:

\frac{\frac{4}{7} }{-\frac{11}{2} }

Multiply by the reciprocal in order to get rid of the fraction in the denominator.

\frac{\frac{4}{7} }{-\frac{11}{2} }*-\frac{2}{11}

\frac{4}{7}*-\frac{2}{11}

-\frac{8}{77}
