Answer:
3.5
Step-by-step explanation:
If x is the volume of 10% solution, and y is the volume of 6% solution, then:
x + 7 = y
0.10x + 0.04(7) = 0.06y
Solve the system of equations.
0.10x + 0.04(7) = 0.06(x + 7)
0.10x + 0.28 = 0.06x + 0.42
0.04x = 0.14
x = 3.5
3.5 liters of 10% solution is needed.
estimate the the nearest half....
5/8....it is closer to 4/8(which is 1/2) then it is to 8/8(which is 1)...so we will round 5/8 to 1/2
8/9....it is closer to 9/9 (which is 1) then it is to 4.5/9 (which is half)...so we will round 8/9 to 1
" the product " means multiply
so 1 * 1/2 = 1/2 (or 0.50) <== estimate
actual : 5/8 * 8/9 = 5/9 (or 0.55) <== actual
<u><em>Answer:</em></u>
0.3
<u><em>Explanation:</em></u>
We are given that:
Probability that a randomly chosen person lives in the East is 0.12
P(East) = 0.12 ..................> I
Probability that a randomly chosen person lives in the West is 0.18
P(West) = 0.18 ............> II
Now, we want to find the probability that the randomly chosen person lives in the East or West
<u>To do this, we will use the following formula:</u>
P(A or B) = P(A) + P(B)
<u>Applying this rule to our givens:</u>
P(East or West) = P(East) + P(West)
P(East or West) = 0.12 + 0.18
P(East or West) = 0.3
Hope this helps :)
