Answer:
(-5p + 2)(-p + 10)
Step-by-step explanation:
-52p + 20
(-5p + 2)(-p + 10)
You can double check this by using the distributive property..
-5p * -p = -5p^2
2*-p = -2p
10*-5p = -50p
10*2 = 20
-5p^2 + -2p + -50p + 20
Now we combine like terms and simplify
-5p^2 -52p + 20
So, we are correct
<span>You take the probability of success (and the revenue generated by it) and the probability of failure (and the cost associated with trying it) and get an expected value:
aP(a) + bP(b)

Answer:
0.25
Step-by-step explanation:
Given that a recently married couple are planning to have four children. They are equally likely to have a boy as well as a girl.
Let X be the no of boys the couples have. X has two outcomes with p = 0.5
X is binomial with n = no of trials = 4 and p =0.5
the probability that they will have three boys and one girl
=
Reqd prob = 0.25
Its B
-130 + 240= 110
110- 56 = 54
So.. 54 is your answer
Answer:
First rectangle: 12 cm by 2 cm
Second rectangle: 8 cm by 3 cm
Step-by-step explanation:
You can examine factor pairs of 24 to see which pairs meet the requirements:
24 = 1×24 = 2×12 = 3×8 = 4×6
Factor pairs (2, 12) and (3, 8) have one factor that differs by 1 and another factor that differs by 4. We can use these numbers to describe the rectangles:
First rectangle: 12 cm by 2 cm
Second rectangle: 8 cm by 3 cm
