Answer:
0.07
Step-by-step explanation:
First, add up all the numbers. This will be the denominator.
4+2+3=9
There are 9 pieces of candy.
Since you are randomly choosing two times you will have to multiply two fractions.
There are M&M's, and
Butterfingers (You simplify)
Now you multiply these.
×
=
Now make this into a decimal. To do this divide 2 and 27. which is approximately 0.07.
Finding the "probability that at least one is girl" can be done much easier by subtracting the "probability that none is girl" from 1, since these 2 events are the complement of each other, and either one or the other, but never both, may happen.
consider the tree diagram of the problem, check the picture, each branching represents a birth. The only branch where there is no girl (no g), is
bbbbbb with a probability of (1-0.534=0.466) per each letter b.
we know that the probability of a particular branch is the multiplication of the probabilities of each letter in the branch.
so in the case, P(bbbbbb)=
finally, P(at least 1 girl) = 1- P(no girl)=1-P(bbbbbb)=1-0.01=0.99
Answer: 0.99

Answer:
the rate of change of James’ salary is $845 dollars per year
y = 845x + 66640
the value of James’ salary in 23 years=$86,075
Step-by-step explanation:
Let x = the years worked and y = Salary in dollars
When x=0 then y = 66640
when x= 8 then y = 73400
Two points are (0,66640) and (8,73400)
Rate of change of salary is the slope
To find slope we use formula
the rate of change of James’ salary is $845 dollars per year
Slope intercept form of equation is y=mx+b
m = 845 , b is the y intercept (initial salary)
so y = 845x + 66640
Now we find out salary in 23 years
plug in 23 for x in the y equation
y = 845x + 66640
y = 845(23) + 66640=86075
the value of James’ salary in 23 years=$86,075
