The common denominator is (x+2)(x-2)
notice that x²-4 is the difference of two square
when you solve it you get (x+2)(x-2). (x+2) can go into (x+2)(x-2).
8 - 7a = - 6a + 9
a = - 1

Answer:
It would be the square root of 36.
Step-by-step explanation:
Answer:
1 / 3^5
1/ 243
Step-by-step explanation:
3^4 ÷ 3^9
We know that a^b ÷ a^c = a^ ( b-c)
3 ^ ( 4-9)
3^ -5
We can rewrite this as a^-b = 1/ a^b
1 / 3^5
We know that 3^5 = 243
1/ 243
Answer:
Step-by-step explanation:
Given that you drew all possible random samples of size 1,000 from the population of LSAT test takers
Plotted the values of the mean from each sample
As per central limit theorem, we find that for sample sizes of minimum 30, the means of all such samples randomly drawn would follow a bell shaped curve with normal distribution irrespective of the original distribution of the population.
Hence here answer is yes, this would be a normal distribution as per central limit theorem.
