Dimas [21]3 years ago

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.

Y=4x−9<br> Complete the missing value in the solution to the equation
weeeeeb [17]

Answer:

<h2>The missing value is 3, and the coordinates are (3,3).</h2>

Step-by-step explanation:

The complete question is

y=4x-9

Complete the missing value in the solution to the equation. (3, ? )

By given, we know that x=3, because coordinates are written like (x,y).

Then, we replace the given coordinate to find y.

y=4x-9\\y=4(3)-9\\y=12-9\\y=3

Therefore, the missing value is 3, and the coordinates are (3,3).

A survey of
Zina [86]

Answer:

0.0208<p<0.0592

Step-by-step explanation:

-Given the sample size is 400 and the desired proportion is 16.

-The confidence interval can be determined as follows:

CI=\hat p\pm z\sqrt{\frac{\hat p(1-\hat p}{n}}\\\\\hat p=x/n=16/400=0.04

#We the use this proportion to find the CI at 95%:

CI=0.04\pm 1.96\times \sqrt{\frac{0.04(1-0.04)}{400}}\\\\=0.04\pm 0.0192\\\\=[0.0208,0.0592]

Hence, the 95% confidence interval is 0.0208<p<0.0592
