I need to calculate X<br><br> 2^x=200<br><br> Solve for x
antoniya [11.8K]
Remember
log(a^z)=zlog(a)
so

notice that 200=2*2*2*5*5, so x cannot be a whole number

take the log base 10 of both sides

log_{10}(2^x)=log{10}(200)
xlog_{10}(2)=log{10}(200)
divide both sides by log_{10}(2)
x= \frac{log_{10}(200)}{log_{10}(2)}

if we used log_{2} instead of log_{10} we would get
x= log_{2}(200) because log_{a}(a^b)=b

The game show contestant spins a spinner with the letters E, W, Y, l and Z on it, then either an easy or a hard question is pick
prisoha [69]

Answer:

  1/5

Step-by-step explanation:

We assume the events are independent, so the probability of the joint event is the product of the probabilities of the individual events.

  P(Y or W) = 2 letters of 5 = 2/5

  P(easy) = 1 of 2 kinds = 1/2

The product of these is ...

  P((Y or W) and (easy)) = (2/5)(1/2) = 1/5

_____

In both cases, we have to assume that each of the possible outcomes is equally likely.
