Answer: Calculate areas for 2 rectangles;

21*9= 189

18*42= 756

make an equation with data you have;

If 189 cost $1.31

756 cost $x

____________

756 *1.31 / 189 = $5.24 cost for second fabric

Second way;

(18x42) / (21x9) = 4 x 1.31 = $5.24

The formula for the sample mean, the margin of error, and the confidence interval.

Sample mean + margin of error = High-end confidence interval

Sample mean - margin of error = Low-end confidence interval

The sample mean is 31.

It is the average value of the set given.

It is calculated as:

Mean = Sum of all the values of the set given / Number of values in the set

We have,

Confidence interval = (27,35).

The margin of error = 4.

The formula for the sample mean, the margin of error, and the confidence interval.

Sample mean + margin of error = High-end confidence interval

Sample mean - margin of error = Low-end confidence interval

Now,

The sample mean = x

x + 4 = 35 ____(1)

x - 4 = 27 _____(2)

From (1) we get,

x = 35 - 4 = 31

From (2) we get,

x = 27 + 4

x = 31

Thus,

The sample mean is 31.

Answer:

-4 would be in the x axes and -1 would be in the y axes

Step-by-step explanation:

I hop i explained it well

The drawing i took dosent want to post

Answer:

Go to the x-axis (horizontal part) and find -4 on your graph. Then go down on the y-axis (vertical part) and look for -1. That's where you're going to plot the point, (-4, -1). I attached a photo to give you a visual.

sorry cant help...if you have any math you need help with I could solve that.

Answer:

= -0.75-0.4

= -1.15

Step By Step

The simplified result of -0.75 - 0.4 is -1.15.

To simplify the expression -0.75 - 0.4

Step 1: Start by subtracting the decimals without considering the signs: 0.75 - 0.4 = 0.35.

Step 2: Now, remember that the original expression had a negative sign in front of it, so the final answer needs to be negative. Since we already calculated a positive value (0.35), we'll make it negative by adding the negative sign: -0.35.

Step 3: Finally, we need to subtract the whole number parts. -0 (whole number part of -0.75) - 0 (whole number part of -0.35) = 0.

Putting it all together, we have -0 - 0.35 = -0.35.

But remember, the original expression had a negative sign, so the final result is -(-0.35), which simplifies to -0.35.

In mathematical terms, -0.75 - 0.4 = -0 - (0.75 - 0.4) = -0 - 0.35 = -0.35.

So, the simplified answer is -0.35, which can also be written as -1.15 (since -0.35 = -1.00 + 0.15).

In summary, when you subtract -0.4 from -0.75, you get -0.35 or -1.15, depending on how you choose to express it.
