Answer:

  d = 15

Step-by-step explanation:

Divide the numbers

\frac{20}{16} =\frac{d}{12}

\frac{5}{4} =\frac{d}{12}

Multiply all terms by the same value to eliminate fraction denominators

12*\frac{5}{4} =12*\frac{d}{12}

Cancel multiplied terms that are in the denominator

12*\frac{5}{4} =d

Multiply the numbers

15=d

Move the variable to the left

d=15

Hence, d= 15.

QUESTION 7.

The probability that exactly 4 of the selected adults believe in reincarnation is 5.184%, and the probability that all of the selected adults believe in reincarnation is 7.776%.

Given that based on a poll, 60% of adults believe in reincarnation, to determine, assuming that 5 adults are randomly selected, what is the probability that exactly 4 of the selected adults believe in reincarnation, and what is the probability that all of the selected adults believe in reincarnation, the following calculations must be performed:

  • 0.6 x 0.6 x 0.6 x 0.6 x 0.4 = X
  • 0.36 x 0.36 x 0.4 = X
  • 0.1296 x 0.4 = X
  • 0.05184 = X
  • 0.05184 x 100 = 5.184

  • 0.6 x 0.6 x 0.6 x 0.6 x 0.6 = X
  • 0.36 x 0.36 x 0.6 = X
  • 0.1296 x 0.6 = X
  • 0.07776 = X
  • 0.07776 x 100 = 7.776

Therefore, the probability that exactly 4 of the selected adults believe in reincarnation is 5.184%, and the probability that all of the selected adults believe in reincarnation is 7.776%.
