Can you help me with this question plzz?​
Dominik [7]

Answer: The answer is 96 wizards.

Step-by-step explanation:

So what I like to do is fraction formatting.

you start with x/blank \frac{blank}{120} and \frac{80}{100} you do cross multiply divide

and multiple 120 by 80(=9600) and divide by 100 (=96) because wizards are 20% less of the population than goblins, so they are equivalent to 80% of the goblins! Hope this helped!

Consider a game in which you flip a coin. If it comes up heads, you earn 1 point; if it comes up tails, you earn 0 points. What
Sergeeva-Olga [200]

Answer:

C. 0.5

Step-by-step explanation:

Since a coin has 2 sides and there is the same probability of getting either side, then each side has a 50% or 0.5 probability. Therefore, in order to calculate the expected value of one coin flip we need to multiply the value of each side by its probability and add those values together like so...

1 * 0.5 = 0.5

0 * 0.5 = 0

Now we add these values together...

0.5 + 0 = 0.5

Finally, we can see that the expected value of one coin flip is 0.5
