Answer: A factory b is produced more tired than Factory A because factory B has a median of 112 and factory A has a median of 102.
There really is no single "obvious" choice here...
Possibly the sequence is periodic, with seven copies of -1 followed by six copies of 0, or perhaps seven -1s and seven 0s. Or maybe seven -1s, followed by six 0s, then five 1s, and so on, but after a certain point it would seem we have to have negative copies of a number, which is meaningless.
Or maybe it's not periodic, and every seventh value in the sequence is incremented by 1? Who knows?
I'll go ahead and assume the latter case, that the sequence is not periodic, since that's technically somewhat easier to manage. We can assign the following rule to the
-th term in the sequence:
for
.
So the generating function for this sequence might be
As to what is meant by "closed form", I'm not sure. Would this answer be acceptable? Or do you need to find a possibly more tractable form for the coefficient not in terms of the floor function?
Answer: 2x+5 = 50
Step-by-step explanation:
Given the total length of the piece of wood is 50" long. If the wood is sawed into two pieces, let's say the length of the two wood pieces are 'x'and 'y'.
This means x + y = 50... (1)
If one piece is 5" longer than the other, it can be written as;
y = x+5... (2) (this means wood of length y is 5" longer than that of wood of length x. To write the problem as an equation, we will substitute equation 2 into 1 to have
x + y = 50
x + (x+5) = 50
2x+5 = 50 (The will be the required equation where x is the length of the shorter piece of wood)
Answer:
D - Type of restaurant - fast food or more expensive.
Step-by-step explanation:
By a lurking variable we mean or refer to any variable that is unknown and not controlled for or out of individual control. When there is one or more lurking variables in any study it could results in accidental bias. According to Soares (1985), lurking variables are intrinsic and they are not actually caused by “accidents” in real sense. Hence he suggests that “lurking-variable bias” is a more suitable name for accidental bias.
Concluding that individuals who spend a lot on groceries also spend a lot at restaurants could be misleading in the sense that, groceries may have a more uniform price than restaurant regardless of your social class. For instance, type of restaurant could determine food cost. At some restaurant, food is quite expensive at another food is quite affordable. I may not to go any groceries store in a month but I patronize restaurant to eat daily.
It is also possible I don't patronize restaurants! And yet, I am frequent at groceries store.
In real sense, what I spent at groceries might be nothing compare to what I spend at restaurant and vice versa. Hence, the possible lurking variable is type of restaurant - fast food or more expensive which is unknown and not controlled for.
Answer:
Step-by-step explanation:
We are given two fractions and are asked to simplify it.
So
We can follow the exponent rule of subtracting them since both fractions are the same value.
Now do the negative exponent rule :
Move the negative in between the fraction :
And apply the fraction switcharoo :
