Answer:
Option a) Compare the level of significance to the confidence coefficient.
Step-by-step explanation:
We are given the following information in the question:
We are performing a two-tailed test hypothesis. We can follow the following approaches:
Option a) Compare the level of significance to the confidence coefficient.
This cannot be used to perform hypothesis.
Option b) Compare the value of the test statistic to the critical value.
If the test statistic lies in the acceptance region evaluated by the critical value, we accept the null hypothesis. If not, we reject the null hypothesis.
Option c) Compare the confidence interval estimate of μ to the hypothesized value of μ.
If the estimated population lies in the calculated confidence interval, we accept the null hypothesis otherwise, we reject the null hypothesis.
Option d) Compare the p-value to the value of α.
If the p-value is greater than the significance level, we accept the null hypothesis. If it is lower than the significance level, we reject the null hypothesis.
Answer: Rikshaw bought it for 100. He lost 12% on selling it, so that means he must have sold it for 88. He wants to make 12% profit, so that means he should have sold it at 112.
But we know that he sold it for 2640.
Therefore, if 88 = 2640, 112 would be 2640*112/88 = 3360.
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
3 times the square root of 2 +2 times the square root of 3 =3sqrt2+2sqrt3
We need to simplify the above expression.
In addition and subtraction, there is a rule of adding or subtracting of like terms is possible only.
But, here, √2 ad √3 are unlike term.
so, we cannot simplified it.
Hence, Option 'D' is correct.

Answer:
They are not equivalent equations
Step-by-step explanation:
d=m/v
Multiply each side by v
d * v = m/v *v
dv = m
Divide each side by d
dv/d = m/d
v = m/d
This is not the same as v = m-d
They are not equivalent equations
