Find the value of x so that the polygons have the same perimeter.
Novosadov [1.4K]

Answer: x=4

Step-by-step explanation:

The perimeter´s formula for this kind of polygons is

The triangle perimeter would be:

(x+2)+(x+3)+(x+3)

And the rectangle:

(x+2)+(x+2)+x+x

For them to have the same value, we should equal them:

(x+2)+(x+3)+(x+3)=(x+2)+(x+2)+x+x

Working with this:

3x+8=4x+4

x=4

Calculate the variance for the data set. Round your answer to the nearest hundredth. Show all of your steps. { 10 , 19 , 21 , 28
GrogVix [38]

Answer:

Variance of the given data = 31.143

Explanation:

  Variance, \sigma^2=\frac{1}{n} \sum_{i=1}^{n}(x_i-\mu)^2, where n is the number of observations, μ is the mean and x_i is the observations made.

   Number of observations, n = 7

   Mean, μ = \frac{10+19+21+28+12+20+16}{7} = 18

   \sum_{i=1}^{n}(x_i-\mu)^2=(10-18)^2+(19-18)^2+(21-18)^2+(28-18)^2+(12-18)^2+(20-18)^2+(16-18)^2\\ \\ \sum_{i=1}^{n}(x_i-\mu)^2=64+1+9+100+36+4+4=218

  \sigma^2=\frac{1}{n} \sum_{i=1}^{n}(x_i-\mu)^2=\frac{218}{7} =31.143

  So variance of the given data = 31.143
