VW = 9
VX is the whole line
VW and WX makes up VX so:
VW + WX = VW, or:
(4x - 7) + (3x) = (5x + 1); add 3x
7x - 7 = 5x + 1; subtract 5x
2x - 7 = 1; add 7
2x = 8; divide 2
x = 4
Now Put 4 in for VW:
(4(4)-7); multiply
(16-7)
9
A woman who is a carrier has: a 25% (one in four) chance of having a daughter who is a carrier. a 25% chance of having a son with hemophilia. and a 50% chance of having a child (boy or girl) who does not have the gene for hemophilia at all
-3b+ac=4
Move c to the left and - 3b to the right
ac-c=-4+3b
Now factor by c at the left
c(a-1)=-4+3b
Divide the right by a-1
C=(-4+3b)/(a-1)
Answer is .5
move decimal place 2 places right
Answer:
The 10% condition would not apply here
Explanation:
The 10% condition is the recommended size of sample from the population to get a non biased result. The 10% condition requires that the sample be not more than 10% of the population.
Tossing a coin is an example of a Bernoulli trial. A Bernoulli trial is one that has two possible outcomes, this face of the coin or the other face of the coin. The 10% condition does not apply to Bernoulli trials that are independent events.
Therefore the 10% condition would not apply here because tossing a coin is an an independent event. An independent event is one with replacement.
