So the question is, what is the smallest number than can be divided into 6,7 and 8?
the numbers have only one non-1 divisor in common: both 6 and 8 are divisible by 3.
so for our purposes we can "delete" one 2 and ask:
what is the smallest number than can be divided into 3,7 and 8 ?
There are no more divisors in common, so we just have to multiply them: 3*7*8=21*8=168
and the 4 marbles "extra"? We add them to this sum.
the the smallest possible number in the box is 168+4=172.

Answer:
y = 15
x = 30
Step-by-step explanation:
Since adjacent are equal, that means all 4 angles are equal to 90 degrees
6y = 90
Divide by 6
6y/6 = 90/6
y = 15
3x = 90
Divide by 3
3x/3 = 90/3
x = 30
Answer:
y = 15
x = 30
Step-by-step explanation:
Sample 2 is a random sample from grades 11 and 12 and consists of the following scores: 84, 86, 87, 84, 86, 89, 90, 87, 87, 84, 86.
Choose the following statements that correctly compare the two samples.
Check all that are true.
A). Sample 2 shows 11th and 12th grade students, on average, did better.
B) . Sample 1 has a higher probability than Sample 2.
C). The measure of center is the same for both samples.
D). Sample 1 shows 9th and 10th grade students, on average, did better.
E). Sample 2 has a higher median score than Sample 1.
Answers
Answer:
E)- Sample 2 has a higher median score than Sample 1.
Step-by-step explanation:
For comparing both samples by the median, We are more clear that Sample 2 (grades of 11th and 12th) is better than Sample 1 (grades of 9th and 10th).
We didn't choose other options because neither only seeing the samples nor by measuring the probability of both samples We do a better comparison of both the samples.
Also by measuring the mean and median of the both given samples we get both Option C and D are incorrect.
