Lydia runs an experiment to determine if a coin is fair by counting the number of times a coin lands heads up. The table shows her data.

A 2-row table with 10 columns. The first row is labeled number of coin flips with entries 0, 10, 20, 30 ,40, 50, 60, 70, 80, 90. The second row is labeled number of heads up with entries 0, 7, 12, 18, 23, 30, 35, 38, 42, 45.

According to the line of best fit, about how many times would the coin land heads up in 100 flips?

48
50
51
53

step-by-step explanation:

im not sure what the answer is

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

the answer would be  

a.

3: 1
