Step-by-step explanation:
Answer:
0.50 × 0.20 = 0.1
Step-by-step explanation:
Data provided in the question:
P( White ) = 50% = 0.50
P( Deaf ) = 11% = 0.11
P( Deaf/White ) = 20% = 0.20
Now,
The probability that a randomly chosen bull terrier is white and deaf
i.e
P( White/Deaf ) = P( Deaf/White ) × P( White )
= 0.20 × 0.50
= 0.1
Hence,
The answer is option 0.50 × 0.20 = 0.1
Answer:
x = −21.25
Step-by-step explanation:
0.4(-0.2x - 3) = 0.5
distribute the .4
.4 * -0.2 = -0.08x and 0.4 * -3 = −1.2
we now have -0.08x - 1.2 = 0.5
next we add 1.2 to both sides
-0.08x - 1.2 + 1.2 ( these two 1.2's cancel out ) = 0.5 + 1.2 ( 0.5 + 1.2 = 1.7)
we then have -0.08x = 1.7
We then divide both sides by -0.08
-0.08/-0.08 = x
1.7 / -0.08 = −21.25
we're left with x = −21.25
