Answer:
Step-by-step explanation:
Let g and b represent the numbers of candy canes the girl and boy have, respectively.
g -1 = b +1 . . . . . . girl gives to boy, they're equal
g +1 = 2(b -1) . . . . boy gives to girl; she has double
Adding 1 to the first equation gives an expression for g that can be substituted into the second equation.
g = b +2
(b +2) +1 = 2b -2
5 = b . . . . . . . . . . add 2-b, simplify
g = 5+2 = 7 . . . . . find g
The girl has 7 candy canes; the boy has 5.
Answer:
Step-by-step explanation:
Rewrite:
Cube both sides:
Divide both sides by 729:
Take the square root of both sides:

Answer:
15 in^2
Step-by-step explanation:
Find the area of the vertical rectangle
A = l*w
A = 6*2 = 12 in^2
Now find the area of the horizontal rectangle
A = l*w
= 3*1 = 3in^2
Add them together
12+3 =15 inch^2
4^3
you can write it like 4 × 4 × 4
you can also call it "Four to the Third power".
Answer:
The probability of having two claims in three days is 0.225.
Step-by-step explanation:
This type of process can be modeled by the Poisson distribution.
This distribution has a rate, that in this case is x: number of claims filled in a one-week period.
The probabilty density function can be written as
In this case, .
The probablity of having two claims in three days is:
The probability of having two claims in three days is 0.225.
