The hours will vary. You have to take into consideration, "the amount of water", "the water pressure" and "what tools am i using to fill it up?"

So the hours will vary.

It depends on how you are filling it. If you are just putting water in by a hose, it will take some time, but not too long. If you are doing a bucket brigade, it will be even shorter. If you happen to be doing both, it will halve the time it takes to begin with.

Answer:

Step-by-step explanation:

Vertically stretched. The action of vertically stretched is accomplished by altering a in

y = a* abs(x)

What that means is that you make a > 1. In this case, a = 2

So far, what you have is

y = 2*abs(x)

Six units down. The action of 6 units down is accomplished by a number added or subtracted to/from absolute(x). down is minus, up is plus.

y = 2*abs(x) - b. Since we are moving down, b<0

y = 2*abs(x) - 6

Four Units Right. This is the tough one because it is anti intuitive. You would think you should be adding something somewhere to get a right hand movement.

Not true.

To move right you subtract something in the brackets.

y = 2*abs(x - 4) - 6

Graph

Just to make things complete, I have graphed this for you. Desmos is wonderful for this kind of problem.

red: y = abs(x)

blue: y = 2*abs(x - 4) - 6

For a sample of n = 30 scores, X = 45 corresponds to z = 1.50 and X = 40 corresponds to z = +1.00. What are the values for the s
TEA [102]

Answer:

30

Step-by-step explanation:

Here, it is given that the Z – score corresponding to the score X = 45 is 1.5 and the Z – score corresponding to the score X = 40 is...

Z = \frac{X - M}{S}

So:

1/ 1.5 = \frac{45 - M}{S} and 1 = \frac{40 -M}{S} . solve the both equations, we found out:

<=> S = 10

=> M = 30

Hence, mean is:

M = 45 -1.5S = 45 - 1.5 (10) = 30

Factor out the coefficient of the variable 1/2q plus 5/2
Iteru [2.4K]
I believe you do it like this:
1/2 Q+5/2
divide 1/2 into each term
to divide multiply by the reciprocal
1/2 x2/1= 1
5/2 x 2/1=5

1/2(Q+5)
