A 44<br> B 5<br> C 10<br> D None of the choices are correct.
Brums [2.3K]

Answer:

D. None of the choices are correct.

Step-by-step explanation:

If <em>B</em> is the midpoint of AC, then that means that AB is congruent to BC. Because this is true, you can set 8x + 4 and 10x - 8 equal.

8x + 4 = 10x - 8

Now just solve for x. Subtract 8x from both sides and add 8 to both sides.

4 = 2x - 8

12 = 2x

Then divide by 2.

6 = x

Another way to do this problem is to set up the same equation, but instead of solving it, plug in answer choices A, B, and C independently of each other. Then simplify to see if those are right. You'll find out that none of them are.

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%.

line k has a slop of -5. Line J is perpendicular to line K and passes through the point (5,9). Create the equation for line j.
sveticcg [70]

Answer:

The equation of the line would be y = 1/5x + 8

Step-by-step explanation:

Since the slope of k is -5, the slope of j has to be 1/5. This is because perpendicular lines have opposite and reciprocal slopes.

Now we can use the slope and the point in point-slope form to get the equation.

y - y1 = m(x - x1)

y - 9 = 1/5(x - 5)

y - 9 = 1/5x - 1

y = 1/5x + 8
