Answer:
(1,4)
Step-by-step explanation:
2x-3y=-10
y=4x
Since the y is already isolated, you can use substitution to find the answer to this equation. Simply replace any y values in the first equation with 4x:
2x-3(4x)=-10
2x-12x=-10
-10x=-10
x=1
y=4(1)=4

We are ____99%____ confident that the population mean is between ___0.385631____ and ___0.780609____.
c) 99%, 0.385631, 0.780609
Step-by-step explanation:
This is the only correct option, given the relevant population mean range. Option B is not correct as the population mean cannot range between 0 and 0.583120 as given by the option. Options 'a' and 'd' are not relevant to the question because they have 1% confidence level, instead of the stated 99% confidence level.

Answer:
Yes.
Step-by-step explanation:
This problem has some different steps, so lets break it down:
Ed has 12 glasses of punch with 120 milliliters of liquid contained each.
Therefore, Ed has 12 * 120 milliliters of liquid:
Now, we need to convert to liters, because that is what Ed's possible answer unit is in. Since there are 1000 milliliters in a liter, we will divide 1440 by 1000.
Thusly, Ed is correct and the answer is .
