Answer:

C. They have the  same chance of winning.

Step-by-step explanation:

Probability (2 tails) = 1/2 * 1/2 = 1/4

Probability( 2 heads = 1/2 * 1/2 = 1/4.

Therefore the Probability  they match = 1/4 + 1/4 = 1/2.

The probability of  they don't match = 1 - 1/2 = 1/2 because all probabilities add up to 1. There are only 4 possible results and their probabilities must add up to 1.

Garvey's Electronic store is having a storewide sale. For a television set with a regular price of x dollars, a 15 percent disco
ratelena [41]
With the equation:
0.15 x = 30
x = 30 : 0.15 = $200
A regular price of TV is $200.
Which could not be used to determine x ( we shall plug in the value 200 ):
A ) 0.15 * 200 = 200 - 30
30 ≠ 170
B ) 0.85 * 200 = 200 - 30
170 = 170 ( correct )
C ) 200 - 0.15 * 200 = 200 - 30
200 - 30 = 200 - 30
170 = 170   ( correct )
D ) 0.15 * 200 = 30
30 = 30  ( correct )
Answer:
A ) 0.15 x = x - 30
