Answer:
$7.20
Step-by-step explanation:
20% is the same as 0.2 or 2/10, which simplifies to 1/5.
1/5*36=36/5=7.20
Or you could straight up to 20%*36=7.20
<span>The term that you want is 5C2*p^2*q^3
representing 2 successes and 3 failures. This term's value is</span>
<span>(5C2)(0.5^5)
= 10*0.03125 = 0.3125 = P(2 successes in 5 trials) =31.3% </span>
Answer:
Marco's age is 7 years old
Step-by-step explanation:
Let
x ----> Marco's age
y ----> Paolo's age
we know that
---->
----> equation A
----> equation B
substitute equation A in equation B


Solve the quadratic equation
The formula to solve a quadratic equation of the form
is equal to

in this problem we have

so

substitute in the formula





Remember that the solution cannot be a negative number
so
The solution is x=7
therefore
Marco's age is 7 years old

Answer:
g(x) = 3x^2 -2
Step-by-step explanation:
Reflection in the y-axis replaces x with -x.
g(x) = f(-x) = 3(-x)^2 -2
g(x) = 3x^2 -2
_____
The given function is symmetrical about the y-axis, so its reflection is itself.
