Answer:

  (A)  20°

Step-by-step explanation:

The relations between angles in a triangle and along a line can be used to find the measure of angle ABE.

<h3>Triangle angles</h3>

The congruence AB = BC tells you that ΔABC is isosceles, and that ∠C = ∠A = 30°. The sum of angles in a triangle is 180°, so the measure of angle ABC is ...

  ∠ABC = 180° -30° -30° = 120°

<h3>Angles on a line</h3>

The sum of angles along a line is 180°, so we have ...

  ∠DBE +∠EBA +∠ABC = 180°

  4x +2x +120° = 180°

  6x = 60° . . . . . . . . . . subtract 120°, collect terms

  2x = 20° . . . . . . . divide by 3

The measure of angle ABE is 20°.

You have to divide 300 with 15, the answer to that is: 300/15=20. However, if she starts saving this week (counting as a first), she will have enough money in 19 weeks after the first week, she needs 20 weeks to save the money.

QUESTION 7.
Elan Coil [88]

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%.
