8 0

Answer:

8 dollars

Step-by-step explanation:

First, convert the yards to decimals, 1/8 is equivalent to .125, therefore 1 1/8 yards is 1.125

Next, since we know that 1 1/8 yards of fabric is $9, we can divide 9 by 1.125 in order to find the cost of one yard of fabric

9/1.125=8, therefore your final answer is $8

Don't forget to put units if this is a test question (or practically in any case), the unit in this case is $(dollars)

Answer:

Part 1) 40% of the 80 ounce bottle of apple juice is water

Part 2) 75% of the 64 ounce bottle of orange juice is water

Part 3) An 64 ounce bottle of orange juice has a greater percent of water

Step-by-step explanation:

Part 1) we know that

An 80 ounce bottle of apple juice contains 32 ounces of water

In this problem

80 ounce bottle of apple juice represent the 100%

using proportion

Find out how much percentage represent 32 ounces of water

Let

x ----> the percentage of ounces of water

$\frac{80}{100}=\frac{32}{x} \\\\x=100(32)/80\\\\x=40\%$

therefore

40% of the 80 ounce bottle of apple juice is water

Part 2) we know that

An 64 ounce bottle of orange juice contains 48 ounces of water

In this problem

64 ounce bottle of orange juice represent the 100%

using proportion

Find out how much percentage represent 48 ounces of water

Let

x ----> the percentage of ounces of water

$\frac{64}{100}=\frac{48}{x} \\\\x=100(48)/64\\\\x=75\%$

therefore

75% of the 64 ounce bottle of orange juice is water

Part 3) which juice has a greater percent of water?

Compare the percentage of ounces of water in both bottles

$75\% > 40\%$

therefore

An 64 ounce bottle of orange juice has a greater percent of water

Answer:

The residual value is -1.8 when x = 3

Step-by-step explanation:

We are given the following table

x | y

0 | -3

2 | -1

3 | -1

5 | 5

6 | 6

Residual value:

A residual value basically shows the position of a data point with respect to the line of best fit.

The residual value is calculated as,

Residual value = Observed value - Predicted value

Where observed values are already given in the question and the predicted values are calculated by using the equation of line of best fit.

$y = 1.6x - 4$

When we substitute x = 3 in the above equation then we would get the predicted value.

$y = 1.6x - 4 \\\\y = 1.6(3) - 4 \\\\y = 4.8 - 4 \\\\y = 0.8$

So the predicted value is 0.8

From the given table, the observed value corresponding to x = 3 is -1

So the residual value is,

Residual value = Observed value - Predicted value

Residual value = -1 - 0.8

Residual value = -1.8

Therefore, the residual value is -1.8 when x = 3

Note: A residual value closer to 0 is desired which means that the regression line best fits the data.
