Yes, the rules of scientific notation are:
1. All non-zero digits are significant
2. Zeros in between non-zeros are significant.
3. Zeros to the left of the first non-zero number are NOT significant.
4. Zeros to the right of non-zero numbers are significant IF a decimal point is present.
P.S: if you need help with sig fig rounding, let me know.
Answer:
Step-by-step explanation:
the 3 equation can not be factorised. Because they will result to fraction
You would multiply 100 by 6 to get the 6 away from m. this leaves m on one side of the equal sign and 6•100 on the other. multiply that out, which is 600. so m=600.
Answer: Choice B
There is not convincing evidence because the interval contains 0.
========================================================
Explanation:
The confidence interval is (-0.29, 0.09)
This is the same as writing -0.29 < p1-p1 < 0.09
The thing we're trying to estimate (p1-p2) is between -0.29 and 0.09
Because 0 is in this interval, it is possible that p1-p1 = 0 which leads to p1 = p2.
Therefore, it is possible that the population proportions are the same.
The question asks " is there convincing evidence of a difference in the true proportions", so the answer to this is "no, there isn't convincing evidence". We would need both endpoints of the confidence interval to either be positive together, or be negative together, for us to have convincing evidence that the population proportions are different.
Answer:
1.125
Step-by-step explanation:
1) First you have to turn it into an improper fraction
8*1 = 8. Add the numerator--> 8+1 = 9.
2) The improper fraction is 9/8
3) Divide 9 by 8
**Write this using long division
8 goes into 9 one time, so we will write one as our first digit
Carry down the 1 and the 0, 8 goes into 10 1 times so write 1.
And this point we have 1.1 above
Carry down the 2 and the 0, 8 goes into 20 2 times so write 2
At this point we have 1.12
Carry down the 4 and the 0, 8 goes into 40 5 times with no remainders so write 5 and end the division process.
Now we have 1.125 as our decimal for 9/8 which is equivalent to 1 1/8.
