12+21x
Step-by-step explanation:
Answer:
the answer is x=2.
Step-by-step explanation:
study
Log3(x)+log3(4)-2log3(3)=2using properties of multiplication of logarithms,log3(x)+log3(4)-log3(3^2)=2log3(x)+log3(4)-log3(9)=2using properties of addition of logarithms,log3(x*4/9)=2raise both sides to exponent of base 33^log3(x*4/9)=3^24x/9=9x=81/4

Answer:
77/134 or 0.5746
Step-by-step explanation:
The approximate relative frequency is "the number of times that the event occurs during experimental trials, divided by the total number of trials conducted."
So we need to identify the number of times the event occured, the amount of times children chose sweet snacks, and the total number of trials conducted. So since the question wants the approximate relative frequency by column, we use the number 134 for the total number, and 77 for the number of times the event occurred. We then divide 77 by 134, which looks like this: 77/134. In decimal form, this equals 0.5746. It can't be simplified anymore in fraction form, so 77/135 would be another way to answer.
