In order for the whole expression to be negative, either (x⁵)
or (y⁴) or (z²) must be negative.
But an even-numbered power can't be negative ... even if the base
is a negative number, any even-numbered power of it is positive.
So (y⁴) and (z²) are always positive. The expression can be
negative if 'x' is negative, because (x⁵) will then be negative.
None of the proposed requirements is appropriate, so the
final answer is E. None .
12% of 16.50 = 1.98
16.50 + 1.98 = $18.48
Answer:
The sum of 3 consecutiveodd number is 27. What are the 3 numbers?
Step-by-step explanation:
Answer:
The nth term for the given sequence can be written as:

Step-by-step explanation:
Notice that this arithmetic sequence is created by adding to each term a common difference of 6 units:
7 + 6 = 13
13 + 6 = 19
19 + 6 = 25
Then, using the general expression for the nth term of an arithmetic sequence of first term "
" and common difference "<em>d</em>" we can write the nth term as:

which in this case translates as:

Answer:
The hypothesis test is right-tailed and the parameter that is being tested is the population standard deviation (
).
Step-by-step explanation:
We are given with the following null and alternative hypothesis below;
Null Hypothesis,
:
= 7
Alternate Hypothesis,
:
> 7
The parameter that is being tested here is the population standard deviation (
). So, the null hypothesis states that the population standard deviation is equal to 7 while on the other hand, the alternate hypothesis states that the population standard deviation is greater than 7.
The above hypothesis test is right-tailed because in the alternate hypothesis, greater than sign is there which means that if the test statistics will be more than the critical value, then the null hypothesis will be rejected.
