Answer:
(a) the initial count of bacteria
(b) the growth factor (per hour)
(c) the initial count in the second study
(d) the difference in initial counts between the two studies
Step-by-step explanation:
(a) 1200 is b1(0), the initial count of bacteria.
__
(b) 1.8 is the growth factor per hour, the factor that multiplies the previous hour's count to get this hour's count.
__
(c) Assuming b2(t) = 1000(1.8)^t, the value 1000 is the initial count of bacteria in the second study, b2(0).
__
(d) The difference between 1200 and 1000 means the first study started with 200 more bacteria than the second study did
(0,1)(2,7)
slope(m) = (7-1) / (2-0) = 6/2 = 3
y = mx + b
slope(m) = 3
use either of ur points...(0,1)....x = 0 and y = 1
now sub and find b, the y int
1 = 3(0) + b
1 = b
so ur equation is : y = 3x + 1....or 3x - y = -1
= 6.37 * 10^4 = 637 * 10^2 = 63700
In short, Your Answer would be Option A
Hope this helps!
Answer:
Three-fifths
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The probability that a randomly chosen point on the grid below is in the blue area is equal to dividing the number of blue squares by the total number of squares
Let
x -----> the number of blue squares
y ----> the total number of squares
so
we have
substitute
simplify
therefore
Three-fifths
Suppose x grams of 8% solution should be mixed to make 100 g of 3% solution.
here we shall have:
the amount of 3% solution in the 100 g will be:
3/100*100=3 grams
the the equation will be, 8% of what quantity becomes 3g?
(8/100)*x=3
hence solving for x we shall have:
0.08x=3
x=3/0.08
x= 37.8 grams
The implication of this is that, when you have 37.5 grams of 8% solution, that will contain 3 of pure chemical and hence when you add more solvent on top of 37.5 g until you reach 100g, that will be 3% solution.
