Divide all the ratios and compare:
8/12 = 0.666
15/10 = 1.5
2/3 = 0.666
6/9 = 0.666
The one that isn't equivalent is 15 over 10
Answer:
-4(3-1)+2
-4x2+2
-8+2= -6
since there is only one - and one + the answer will be negative
Answer:

Step-by-step explanation:
-For a known standard deviation, the sample size for a desired margin of error is calculated using the formula:

Where:
is the standard deviation
is the desired margin of error.
We substitute our given values to calculate the sample size:

Hence, the smallest desired sample size is 23
No this is the awnser-3x+y=2
