I tried helping but failed ☹️ your guess is as good as mine
Answer:
N= -8
Step-by-step explanation:
you will add 10and 6 to get 16
then add 8 to each side to cancel out. 16+8 will give you 24. now subtract the 8 off of in onto 5n
5-8 will give you -3. Now you need to divide -3 off of N on both sides so it cancels. -3÷-3=N....24÷-3=-8. Giving you N=-8
<span>Item Number of Liters Percentage of LemoneA 4 14%B x 8%Result 4+x 10%
For a mixture of solutions to form a resulting solution, we know
V1 * N1 + v2 * N2 = V * N
where, V1 = Volume of mixture of 1 N1 = Concentration of mixture 1V2 = Volume of mixture of 2 N2 = Concentration of mixture 2
V = volume of mixture N = Concentration of mixture
So solving we get:
(4+x)*10 = 4*14 + x * 8or, 10x-8x = 4*14-4*10or, 2x = 16or x = 8
so 8 litres of the solution B must be added to the solution<span>

Step-by-step explanation:
Graph 1 is a parabola and has 2 x points and a turning point
meaning it has a minimum and a maximum point.
conclave points are the highs and lows, once you show this in table then you can interpreted them on a graph see the examples attached.
Graph 1 is opposite to shown interpreted conclave so instead of --c++
we write + + c - - and draw on quadrant 1 instead of quadrant 3
graph 2 is decreasing so instead of -+ c then + + it would show + - c then - - so the curve stays in quadrant 3 and 4. Also where c is we draw a 0 and say whether it is minimum or maximum point.
Both graph 1 and 2 demonstrate minimum points for their f(x) for c.
so in your workings within the table you write min as seen in red within the attachment. They wrote max, but you write min as you are in decreasing conclave fx values that reach min point c then they increase and become parabolas.
Answer: 0.965
Step-by-step explanation:
Given : Water use in the summer is normally distributed with


Let X be the random variable that represents the quantity of water required on a particular day.
Z-score : 

Now, the probability that a day requires more water than is stored in city reservoirs is given by:-

We can see that on comparing the above value to the given P(X > 350)= 1 - P(Z < b) , we get the value of b is 0.965.
