Answer: choice C
Step-by-step explanation:
The union of events A and B, denoted ∪ , is the collection of all outcomes that are elements of one or the other of the sets A and B, or of both of them. It corresponds to combining descriptions of the two events using the word “or.”
**keep in mind that we don’t write numbers more than once in these sets(choiceB)
so the answer would be
{3,4,5,6,7,8,9}
Answer:
A. Statistic
Step-by-step explanation:
Usually whole population is difficult to cover so the part of population is considered to assess the aspects of population. The statistic is the quantity which summarizes the sample. The problem illustrate that summary measure is calculated from sample to describe a population. As the summary measure is computed from sample then it is a statistic.
1 pound is 16 ounces
32 ounces is 32 ÷ 16 = 2 pounds
1 pound of Botcoil ⇒ 1.5
2 pounds = 1.5 × 2 = 3
Answer: 12 hours
Step-by-step explanation:
Given : Working together, it takes Sam, Jenna, and Francisco two hours to paint one room.
When Sam works alone, he can paint one room in 6 hours. When Jenna works alone, she can paint one room in 4 hours.
Let 't' be the time taken by Francisco to paint one room on his own.
Then , we have
Rate of work of Sam +Rate of work of Jenna + Rate of work of Francisco =Rate of work they all do together
i.e. 
i.e. 
i.e. 
i.e. 
i.e. 
i.e. 
i.e. t= 12
Hence, Francisco would take 12 hours to paint one room on his own.
A line has the following standard equation form:
y = m x + b
where m is the slope and b is the y intercept
So if Ariel cannot find the slope, then this would only
mean that m = 0, there is no slope. And hence the line is either a straight
vertical line or straight horizontal line.
Answer:
<span>There is no slope</span>
