Answer:
Step-by-step explanation:
85/1000 because we said that 1 meter = 1000 mililiters
Divide both sides by 5 and then you have 17/200
then divide both sides by 2 (to get it over 100) =
8.5/100
.085%
Hope that helps!!
You could also just do 85/1000 you would get the same answer!!
Answer:
X = {8n – 7n – 1 : n ϵ N}
Y = {49 (n –1) : n ϵ N} — (1) [all terms divisible by 49]
X = {8n – 7n – 1}
= (1 + 7)n – 7n – 1
= 1 + nC1 7 + nC2 72 + ….. + nCn 7n – 7n – 1
= nC2 72 + …… + nCn 7n
= 49 [nC2 + nC3 7 + …. nCn 7n-2] — (2)
From (1) and (2),
X is divisible by 49.
Y has all multiples of 49.
X ⊂ Y
Answer:
A. 0.6
B. 0.3
Step-by-step explanation:
For part A we use the the general probability addition rule for the union of two events that states
P(A∪B) = P(A) + P(B) − P(A∩B)
Making P(A∩B) the subject of the equation above
P(A∩B) = P(A) + P(B) − P(A∪B)
P(A∩B) = 0.8 + 0.7 - 0.9
P(A∩B) = 0.6
B.
The description in terms of A and B is:
P(A but not B) + P(B but not A) = P(A∩B') + P(B∩A')
where A' is compliment of set A and B' is compliment of set B
The above description means either it exceeds in July or in January (exactly in one of the two months)
P(A∩B') = 0.8 − 0.6
P(B∩A') = 0.7 − 0.6
P(A∩B') + P(B∩A') = 0.3
Answer:
b
Step-by-step explanation:
In y=mx+b form, the b is the y-intercept, therefore where the line crosses the y-axis on the graph. In this graph, the line crosses the y-axis at 100. This means that the "b" value is 100. So far, our equation is y=mx+100.
Next, to find m, you go to any other point on the graph and see how much units (rise over run) you went to get there. I picked the point (2,150), You can see that it took me 1 unit up and 2 units to the right to get to that point, leading us to believe the slope is 1/2.
Finally, put everything together and you get the answer of y=1/2x+100 (the letters do not matter) :)
Answer is 175
To start you need to work backwards from the mean so do 158*4 to give you the total of the revenue then simply minus what was given to get 175
Hope this helped
