Answer:
x + 4
Step-by-step explanation:
Sine the bases are all the same, I can write the equation:
3x+4 = (x-2) 2^3 When we are adding with logs, that means to multiple. Also, when we have 3 log 2, that can be written as 2^3 or 8 (2x2x2)
3x+4=(x-2)8
3x+4 = 8x-16
4=5x-16
20 = 5x
4=x
Answer:
Simple random sampling
Step-by-step explanation:
In this example, the teacher takes a random 40-student sample from the whole population of students. The fact that the students are alphabetically order does not interfere in the sampling process since students are picked at random. Therefore, the teacher applied the simple random sampling method.
This method provides an unbiased representation of the population.
When dividing fractions, theres this thing you do call "keep, change, flip"
You keep the first fraction the same, change the division to a multiplication, and change the fraction to have the numbers flipped.
4 = 4/1
1 1/8 = 9/8
4/1 * 8/9 = 32/9
32/9 = 3 5/9
3 5/9 is the final answer
Answer:
No, the correct answer is 13/45
Step-by-step explanation:
Find the greatest common factor and change the equations
8/9 -> 40/45
3/5 -> 27/45
40/45 - 27/45 = 13/45
13/45 is the correct answer
Answer:
11/26
Step-by-step explanation:
we know that there are 26 different letters in the alphabet.
In the word PERMUTATIONS there are 11 different letters (letter T is repeated twise, so we count it once)
so the probebility is 11/26
