3pi r 2 603.43 is the answer
Answer:
since highest degree is 2 the degree of a polynomial is also 2.
since the highest exponent is 2 the leading coefficient is 1.
Step-by-step explanation:
(0,-9) or (1,-7) or (2,-5) either one would be correct
The critical values are fixed values which can be
obtained from the standard t crit
tables. We can find the critical value tc when the degrees of freedom
and confidence level are given. The degrees of freedom is simply:
Degrees of Freedom = Number of samples – 1
Degrees of Freedom = 19 – 1
Degrees of Freedom = 18
From the t critical tables, the tc corresponding to Degrees
of Freedom equal to 18 and Confidence level equal to 95% is as follows:
tc = 2.101
Therefore this means that any t value beyond 2.101, we already
reject the null hypothesis.
