You can use greatest common factor(gcf)
list the factors of 18 and 30.
18- 1, 2, 3, 6, 9, 18
30- 1, 2, 3, 5, 6, 10, 15, 30
now the factor that is greatest is 6.
this mean you can use the largest square tile of 6in by 6in without overlap or cutting.
Answer:
X≤10/7
Step-by-step explanation:
7x-4≤6
add 4 both sides
7x-4+4≤6+4
7x≤10
divide 7 both sides
7x/7≤10/7
x≤10/7
hope it's helpful ❤❤❤❤
THANK YOU.
6/18
=1/3
=0+1/3
=0=0.3
Remember: Put a notation bar (or line) above the top of the number 3. This means it repeats continuously as a decimal.

<span>Hope this helps!
Note that even though it's uneven, just think of it as a line on top of 3 in (0.3). :)

Answer: C
Step-by-step explanation: Since there are 5 teachers, you can only have 4/5 samples with the minimum age of 23, and one sample w/the next lowest minimum age of 34, because you can only have samples of 4 teachers at a time.
Answer:
D) 0.78, 0.029
Step-by-step explanation:
Central Limit Theorem:
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean
and standard deviation 
About 78% of the US, population claims that they visit the dentist at least once a year.
This means that 
Random sample of 200 people:
This means that 
Mean and standard deviation of the sampling distribution:
By the Central Limit Theorem
Mean 
Standard deviation 
So the correct answer is given by option D.
