Answer:
2⁸
When dividing a number by another with the same base, you can simply subtract the denominator's exponent from the numerator's. That gives you
2⁴ ⁻ ⁽⁻⁴⁾ = 2⁽⁴ ⁺ ⁴⁾ = 2⁸
Answer:
4.1 shirts
Step-by-step explanation:
Mean can be found by adding all data points and dividing that by the total amount of data points.
There are 12 students selling shirt, which gives you 12 data points.
So (3+4+8+5+2+5+0+5+3+4+3+7)/12 = 4.083...
Which rounds to 4.1 shirts
Remember these two combinations: logab=loga+logb, log(a/b)=loga-logb
3logx=logx^3
(1/2)log(x+2)=log(x+2)^(1/2)
2log(z-4)=log(z-4)^2
so the given expression can be combined into log{[(x^3)(z-4)^2]/(x+2)^(1/2)}
1mm:1m
since its just one to one, thats the ratio
