A set of ordered pairs does NOT represent a function when an input(x value) has multiple outputs(y value). The input can only have one output.

For the first one the answer is B because when x is 2, it has multiple y values. (2, 2) and (2,7)

For the second one the answer is B because A, C, and D have inputs(x values) that have multiple outputs(y values)

What is the solution of the system? use elimination . -12x-y=6 17x+y=4
anyanavicka [17]
To clarify the systems of equations:

-12x - y = 6
17x + y = 4

We already have opposite coefficients for y, so combine the two equations together:

5x = 10

Divide both sides by 5 to get x by itself:

x = 2

Because we now know x, we can plug it into one of the equations.

We will plug this value into the first equation:

-12(2) - y = 6

-24 - y = 6

Add 24 to both sides.

-y = 30

Divide both sides by -1 to get y by itself.

y = -30

Using elimination, x = 2 and y = -30.

General Logs Banana Bombs cereal is sold in 10.40 ounce packages. Because the cereal is sold by weight, the number of pieces of
emmasim [6.3K]

Answer:

The 99% confidence interval for the true mean number of Banana Bombs in 10.40 ounce packages is between 689.3 and 703.86.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1 - 0.99}{2} = 0.005

Now, we have to find z in the Ztable as such z has a pvalue of 1 - \alpha.

That is z with a pvalue of 1 - 0.005 = 0.995, so Z = 2.575.

Now, find the margin of error M as such

M = z\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 2.575\frac{12.33}{\sqrt{19}} = 7.28

The lower end of the interval is the sample mean subtracted by M. So it is 696.58 - 7.28 = 689.3 pieces

The upper end of the interval is the sample mean added to M. So it is 696.58 + 7.28 = 703.86 pieces

The 99% confidence interval for the true mean number of Banana Bombs in 10.40 ounce packages is between 689.3 and 703.86.

In your own words explain why you need to first find the common denominator when adding/subtracting fractions and you do not nee
Elena-2011 [213]
You need a common denominator while subtracting because really a fraction is a division problem and you cannot do 4/5-8/9 it does not make sense as for multiplication you really just multiplying everything that is why it makes sense.
