I you think about it 12a with the 2 on the rope is actually 144 because it’s multiplied by 12 so maybe that helps?
This is g composed of f of x where we first find f(x) then plug that into g(x)
g(f(-1))
g(2 * -1 + 3)
g(1)
1/4
Mean (μ) = 11.5 feet
Standard deviation (σ) = 1.7 feet
First we need to find the z-score for less than 13.5 feet.
The formula of z-score is : z = (X - μ)/σ
Here X= 13.5, so z = 
z = 
= 1.18
P(X < 13.5) = P(z< 1.18) =P(z< (1.1 + .08)) = 0.8810 (from z-score table)
P(X< 13.5) = 88.1% (for making percentage from decimal, we need to multiply by 100)
So, the probability that a randomly selected tree is less than 13.5 feet tall = 88.1%
Answer:
the pair solution is : (10;5)
Step-by-step explanation
d + e = 15
....(1)
–d + e = –5
....(2)
add (1) and (2) : 2e =10
e = 5
put the value of : e in (1) or (2) : d + 5 = 15
d = 10
In this question, you're trying to figure out what property is being represented.
Your answer would be the Distributive Property
This is your answer because as you can see, you are "distributing" the 2 to the variables inside the parenthesis.
When you distribute the number, you would be multiplying, in which in this case there is multiplication.
Therefore, Distributive property would be the correct answer.
