The random numbers below represent 10 trials of a simulation 2632, 1365, 9367, 2056, 0026,

The numbers 0-7 represent students who watched television last night, and the numbers 8 and 9 represent students who did not. Based on the
simulated data, what is the probability that exactly 2 out of a group of 4 randomly selected seventh-graders watched television last night?

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

it is 10.6 according to my calculations

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:
