Answer:
C. 101 - 5(n - 1)
Step-by-step explanation:
d = (26 - 71)/(16 - 7)
d = -45/9
d = -5
a7 = a1 + (7-1)(-5)
71 = a1 - 30
a1 = 101
an = 101 + (n - 1)(-5)
an = 101 - 5(n - 1)
Answer:
The answer is D: The inequality symbol in the alternative hypothesis points away from the critical region.
Step-by-step explanation:
We usually have a one-tailed and two-tailed tests. Examples of a one-tailed test are the left-tailed and the right tailed test. These tests are referred to as one-tailed tests because the critical region or rejection region is located in only one tail. The critical region of a left or right tailed test is that region that correlate with the rejection region and is usually located in extreme left or right tail. Furthermore, tails in a distribution are usually the extreme critical regions also known as the rejection regions which are bound by critical values. However there is nothing that suggests the statement in Option D when talking about tails in a distribution.
Answer:
The number they would count is 
Step-by-step explanation:
One mole is equal to 6.02214076x10^23 particles. In order to know the number counted by every human on Earth we simply multiply the number of humans times the count a "good counter" can achieve, 4x10^9x7.44x10^9 (for USA, change to 4x10^12 if you use de British English definition). Thus:

<h3>
Answer: 7/19</h3>
Explanation:
There are 7 blue marbles out of 4+7+8 = 11+8 = 19 total
The probability of selecting blue is therefore 7/19
We cannot reduce 7/19 any further because 7 and 19 have no common factors other than 1.
