$\frac{1}{12} \times \frac{1}{3} \\ = \frac{1 \times 1}{12 \times 3} \\ = \frac{1}{36}$

When you want to multiply 2 fractions, merge the fractions together & then multiply the numerator first & then the denominator. After that, simplify to the lowest form if possible.

Answer:

$3^{ -x+3}$

Step-by-step explanation:

We need to simplify out the given exponential expression . The given expression to us is ,

$\rm\implies \dfrac{\dfrac{1}{3}}{3^{x-4}}$

We can use the Law of Exponents to simplify the given expression . Recall that ,

$\rm\implies \red{\dfrac{a^m}{a^n}= a^{m-n}}$

Note that , we can write ,

$\rm\implies \dfrac{1}{3}= 3^{-1}$

Therefore our expression becomes ,

$\rm\implies \dfrac{ 3^{-1}}{3^{x-4}}$

Simpify using the Law of Exponents ,

$\rm\implies 3^{ -1 - ( x - 4 )}$

Open the brackets in exponent ,

$\rm\implies 3^{ -1 - x +4 }$

Simplify to get final expression ,

$\rm\implies \boxed{\quad \blue{ 3^{-x+3} \quad}}$

An insurance company makes money according to earnings = p(e1)w1 + p(e2)w2, where p(e1) = 0.002641, w1 = -$25,000, p(e2) = 0.997

evablogger [386]

To put it simply, what needs to be done in order to answer the question is to substitute the known values from the given to the equation that is also already in the given above,

E = (0.002641)(-$25000) + (0.997359)(193.08)

Simplifying the equation,

E = 126.545

Answer: $126.545
