Given:
The recursive formula of a geometric sequence is
To find:
The explicit formula of the given geometric sequence.
Solution:
We know that, first term of geometric sequence is .
Recursive formula of a geometric sequence is
...(i)
where, r is common ratio.
We have,
...(ii)
On comparing (i) and (ii), we get
The explicit formula of a geometric sequence is
Putting and , we get
Therefore, the correct option is D.
Answer:
The right option is:
b. There is enough evidence to conclude the mean difference in pulse rates before and after the 5 minute waiting period is different from 0.
Step-by-step explanation:
The null hypothesis is the opposite to the claim that the researchers are trying to prove. In this case, it will state that there is no difference in the mean pulse rates or, in other words, that the mean difference in pulse rates before and after the 5 minute waiting period is 0 (μ=0).
The claim of the researchers, that will be expressed in the alternative hypothesis, is that the mean difference in pulse rates before and after the 5 minute waiting period differs from 0 (μ≠0).
If the null hypothesis is rejected, is because the test shows that there is enough evidence to support the claim that the mean difference in pulse rates before and after the 5 minute waiting period differs from 0 (true alternative hypothesis).
Note: If the null hypothesis wasn't rejected, the conclusion would have been that there is no evidence o support the claim that the mean difference in pulse rates before and after the 5 minute waiting period differs from 0.
The right option is:
b. There is enough evidence to conclude the mean difference in pulse rates before and after the 5 minute waiting period is different from 0.
C+b=d/a
c=(d/a) -b
Hope i helped
Answer:
46degrees
Step-by-step explanation:
The sum of angles of exterior angles of a quadrilateral is 360 degrees
Hence;
72 + 58+2x+3x = 360
130 + 5x = 360
5x = 360-130
5x = 230
x =230/5
x = 46 degrees
Hence the vale of x is 46degrees
