K=6.5
We move all terms to the left:
k-(6.5)=0
We add all the numbers together, and all the variables
k-6.5=0
We move all terms containing k to the left, all other terms to the right
k=6.5
The answer is 88/5, which is 17.6.
Y=2x-3
If u put in the values of x U will see that it equals the corresponding y value.
-3x-3 is the correct answer
Answer:
26
Step-by-step explanation:
When you flip two coins, you can have 4 different outcomes:
HH
HT
TH
TT
All outcomes are equally likely, but notice that if you do not keep track of which coin is which, you will get 1/4 of the flips to be both heads, 1/4 of the flips to be both tails, and 1/2 of the flips to be one heads and one tails.
p(both heads) = 1/4
With 105 flips, the expected number of both heads is
105 * 1/4 = 26.25
Answer: 26
