Domain is what can be put into the function to make it work
Considering that there are no numbers that 3x^2 cannot handle then the domain is all real numbers
Answer: A
Step-by-step explanation:
The sum to infinity of a geometric series is
S (∞ ) = \frac{a}{1-r} ( - 1 < r < 1 )
where a is the first term 8 and r is the common ratio, hence
S(∞ ) = {8}{1-\{1}{2} } = {8}{1}{2} } = 16
Answer:
and ![H_{a}: \mu > 185](https://tex.z-dn.net/?f=H_%7Ba%7D%3A%20%5Cmu%20%3E%20185)
Step-by-step explanation:
The null hypothesis
states that a population parameter (such as the mean, the standard deviation, and so on) is equal to a hypothesized value. We can write the null hypothesis in the form ![H_{0}: parameter = value](https://tex.z-dn.net/?f=H_%7B0%7D%3A%20parameter%20%3D%20value)
In this context, the investigator's null hypothesis should be that the average total weight is no different than the reported value by the FAA. We can write it in this form
.
The alternative hypothesis
states that a population parameter is smaller, greater, or different than the hypothesized value in the null hypothesis. We can write the alternative hypothesis in one of three forms
![H_{a}: parameter > value\\H_{a}: parameter < value\\H_{a}: parameter \neq value](https://tex.z-dn.net/?f=H_%7Ba%7D%3A%20parameter%20%3E%20value%5C%5CH_%7Ba%7D%3A%20parameter%20%3C%20value%5C%5CH_%7Ba%7D%3A%20parameter%20%5Cneq%20value)
The investigator wants to know if the average weight of passengers flying on small planes exceeds the FAA guideline of the average total weight of 185 pounds. He should use
as his alternative hypothesis.
Answer: The 12.81 for 14 lbs of apples is the better buy.
Step-by-step explanation:
Find the unit price (the price of 1 lb of apples)
7.64/8 lbs = 0.955 per pound
12.81/14 lbs. = 0.915 per pound;
B.
The Probability of choosing a girl is 17/30.
The probability of choosing an A student is 5/30
<span>The P(girl) + the P(A student) = 17/30 + 5/30 = 22/30 = 11/15.</span>
