Answer:
The amount of chamomile tea that has to be used in order to obtain a mixture that costs $14.32 per pound is 8.997 pounds
Step-by-step explanation:
In order to find out the amount of chamomile tea that must be used in the mixture to obtain a 14.32 $ per pound, we can use an weighted average where the price points for each kind of tea are the weights and "c" is the amount of chamomile that we have to use in order to obtain the price per pound that we want. So we have:
(18.5*c + 12.23*18)/(c + 18) = 14.32
18.5*c + 220.14 = 14.32*(c+18)
18.5*c + 220.14 = 14.32*c + 257.76
18.5*c - 14.32*c = 257.75 - 220.14
4.18*c = 37.61
c = 8.997 lb
<h2>
C. { HH, HT , TH, TT}</h2>
Step-by-step explanation:
Sample Space of any event E is the set of all possible outcomes whenever that event takes place.
Here, event E : Tossing 2 coins
Now, as we know, when an unbiased coin is tossed,
The total outcomes = {Head, Tail}
So, when two coins are flipped, the total outcomes are 2 x 2 = 4.
Sample space = { Head Head, Head Tail, Tail Head, Tail Tail}
or, S = { HH, HT , TH, TT}
Answer:
10^5 = 100.000
Step-by-step explanation:
We know that 10^5 = 10 * 10* 10 * 10 * 10 = 100.000.
So, we have that 10^5 = 100.000
Answer:
x = -3
y = 6
Step-by-step explanation:
3x + y = -3
x = -y + 3
3x + y = -3
3(-y + 3) + y = -3
-3y + 9 + y = -3
-3y + y + 9 = -3
-2y + 9 = -3
-2y = -3 - 9
-2y = -12
y = -12/-2
<u>y = 6</u>
x = -y + 3
x = -6 + 3
<u>x = -3</u>
