The area of a rectangle is 294.4 sq.cm. The length of one side is 16cm. What is the perimeter?
Shkiper50 [21]

the perimeter is 68.8cm

Ok so because this is a rectangle the line directly across (paralell) is equal, so if one line is 16cm, the line parallel to that will also be 16. Then the formula for area is LxW we'd plug in the numbers we know to get 294.4cm^{2} =16 x W

then we divide 16 by both sides to make it even to get 18.4cm=W. Now we just plug everything in to the perimeter by doing 16 x 2 + 18.4 x 2 to get

You took a random sample of 12 two-slice toasters and found the mean price was $61.12 and the standard deviation was $24.62. Con
Minchanka [31]

Answer:

Step-by-step explanation:

We want to determine a 95% confidence interval for the population mean for the prices of slice toasters.

Number of sample, n = 12

Mean, u = $61.12

Standard deviation, s = $24.62

For a confidence level of 95%, the corresponding z value is 1.96.

We will apply the formula

Confidence interval

= mean ± z ×standard deviation/√n

It becomes

61.12 ± 1.96 × 24.62/√12

= 61.12 ± 1.96 × 7.107

= 61.12 ± 13.93

The lower end of the confidence interval is 61.12 - 13.93 =47.19

The upper end of the confidence interval is 61.12 + 13.93 = 75.05
