To get the total cost. Given the cost of the sofa to be

\text{ \$940}

We will first find the amount of the tax paid, we will find 6.5% of the sofa

6.5\text{ \% of \$940}

This will be

\frac{6.5}{100}\times940=\frac{6110}{100}=\text{ \$61.10}

The final step will be to add up the tax and that of the sofa

\text{ \$940+ \$61.1= \$1001.1}

Therefore, the total cost will be

\text{ \$1001.1}0

The equation y=2.54x gives the length y in centimeters corresponding to a length x in inches. What is the length in centimeters
bija089 [108]
The equation given in the question is
y = 2.54 x
In this equation, x is in cm and y is in inches
Size of the ruler = 1 foot 
                          = 12 inches.
Putting the value of 12 inches in the equation, we get
y = 2.54x
   = 2.54 * 12
   = 30.48 cm
From the above deduction, we can conclude that the length of the ruler is 30.48 cm. I hope that this is answer that you were looking for and the answer has come to your desired help.

Answer:

The upper endpoint of the 99% confidence interval for population proportion is 0.13.

Step-by-step explanation:

The confidence interval for population proportion is:

CI=\hat p\pm z_{\alpha /2}\sqrt{\frac{\hat p(1-\hat p)}{n}}

<u>Given:</u>

<em>n</em> = 1000

\hat p = 0.102

z_{\alpha /2}=z_{0.01/2}=z_{0.005}=2.58

*Use the standard normal table for the critical value.

Compute the 99% confidence interval for population proportion as follows:

CI=\hat p\pm z_{\alpha /2}\sqrt{\frac{\hat p(1-\hat p)}{n}}\\=0.102\pm 2.58\times\sqrt{\frac{0.102(1-0.102)}{1000}}\\=0.102\pm0.0248\\=(0.0772, 0.1268)\\\approx (0.08, 0.13)

Thus, the upper limit of the 99% confidence interval for population proportion is 0.13.

Is -10 -5 equal to -10+(-5)?Explain in terms of additive inversed.
laiz [17]
Yes because they both equal -15 because you actually turn -10+(-5) into a subtraction problem because if there's a + and -, you actually turn it into a minus and the answer is -15.
