Answer:
(C)
Step-by-step explanation:
Given the distance, d(t) of a particle moving in a straight line at any time t is:
To find an expression for the instantaneous velocity v(t) of the particle at any given point in time, we take the derivative of d(t).
The correct option is C.
Solution :
To claim to be tested is whether "the mean salary is higher than 48,734".
i.e. μ > 48,734
Therefore the null and the alternative hypothesis are
and
Here, n = 50
s = 3600
We take , α = 0.05
The test statistics t is given by
t = 2.15
Now the ">" sign in the sign indicates that the right tailed test
Now degree of freedom, df = n - 1
= 50 - 1
= 49
Therefore, the p value = 0.02
The observed p value is less than α = 0.05, therefore we reject . Hence the mean salary that the accounting graduates are offered from the university is more than the average salary of 48,734 dollar.
Answer:
Step-by-step explanation:
Given an hyperbola with the following conditions:
- Foci at (-10,0) and (10,0)
- x-intercept +/- 6;
The following holds:
- The center is midway between the foci, so the center must be at (h, k) = (0, 0).
- The foci are 10 units to either side of the center, so c = 10 and
- The center lies on the origin, so the two x-intercepts must then also be the hyperbola's vertices.
Since the intercepts are 6 units to either side of the center, then a = 6 and
Therefore, substituting and
