Answer:

(4)

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - $\frac{2}{3}$ x - 5 ← is in slope- intercept form

with slope m = - $\frac{2}{3}$

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-\frac{2}{3} }$ = $\frac{3}{2}$ → (4)

YOU HAVE 8 COINS IN A BAG. 3 OF THEM ARE UNFAIR AND THEY HAVE 60% CHANCE OF COMING UP WITH HEAD WHEN FLIPPED. YOU RANDOMLY CHOSE

madreJ [45]

Answer:

0.29125 or 29.125%

Step-by-step explanation:

For the five fair coins, the probability of coming up head when flipped is 0.5, so for two flips: 0.5*0.5 = 0.25, for each of these coins. So, the probability to take on of them is 5/8, and the probability of coming up with head: (5/8)*0.25 = 0.15625.

For the unfair coins, the probability of coming up with heads is 0.6, so for two flips: 0.6*0.6 = 0.36 for each unfair coins. The probability to chose one of them is 3/8, and the probability of coming up with head: (3/8)*0.36 = 0.135.

These probabilities are dependent, so to have the total probability we must sum them:

P = 0.15625 + 0.135

P = 0.29125 or

P = 0.29125 x 100% = 29.125%
