- Exponents:
- Add:
- Simplify:
- Evaluate:
- Round:
he example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7. Plug in the x value in to the first equation to find out the y value...
Answer:
A = 100.48 cm^2
Step-by-step explanation:
A = (π * r^2) /2
A = (3.14 * 8^2) /2
= (3.14 * 64) /2
= 200.96 / 2
= 100.48 cm^2
Answer: No, the means in the two studies significantly is not different at the 95% confidence level.
Step-by-step explanation:
Since we have given that
Study 1,
Mean = 30.8,
Standard Deviation = 6.2,
Sample size = 100
And
Study 2
Mean = 32.2,
Standard Deviation = 5.4,
Sample size = 200
So, Hypothesis would be
So, At 95% confidence level, z = 1.96
So, the test statistic value would be
Since 1.96>-1.9228
So, we will accept the null hypothesis.
Hence,No, the means in the two studies significantly is not different at the 95% confidence level.
