Kisachek [45]

Answer: \frac{1}{4}=2^{(-2)}

Step-by-step explanation:

You know that an expression written is logarithmic form is:

x=log_b(y)

And an expression equivalent to the expression above that is written in exponential form is:

y=b^x

Therefore, keeping the information above on mind, you have that an equivalent exponential equation for log_{2}(\frac{1}{4}) =-2 , is the shown below:

\frac{1}{4}=2^{(-2)}

A furniture store is having a sale on sofas and you're going to buy one. The advertisers know that buyers get to the store and t
MrRissso [65]

Answer:

$290

Step-by-step explanation:

We are told that 1 out of 5 buyers change to a more expensive sofa than the one in the sale advertisement.

Now we are told that the advertised sofa is $250 and the more expensive sofa is $450.

Thus;

P(x) for expensive sofa = 1/5

P(x) for sofa in sale advertisement = 4/5

Thus, expected value is;

E(X) = (1/5)450 + (4/5)250

E(x) = 90 + 200

E(x) = $290
