Answer:
A. 2/5
B. 1/10
Step-by-step explanation:
First off we need to calculate the probability that the chosen child is a girl So to calculate this probability, we have to know the num. of girls which is seen in the table. There are a total of 8 girls.
Therefore the probability of a girl being chosen is equivalent to the number of girls/exact number of children = 8/20 = 2/5 simplified.
Now to find the probability that the chosen girl is left-handed.
The amount of left-handed girls there is only 2. therefore the probability of selecting a left-handed girl will be 2/20 = 1/10 simplified.
Standard form of an equation can be represented by ax^2 + bx + c = y. where a b are coeficients and c is a constant value. for your equation to work we have to say:
a = -1
b = 4
c = -7
you have to be sure to put the negative value. if i said
a = 1
b = 4
c = 7
and i plugged these in i would get:
(1)x^2 + (4)x + (7)
which becomes
x^2 + 4x + 7
this is not right. if i used the first values i stated then:
(-1)x^2 + (4)x + (-7)
-x^2 + 4x - 7
this is correct
