Answer:

Step-by-step explanation:

In a Parallelogram , it is important to note that opposite sides are equal to each other.

We are given parallelogram ABCD.

We have sides: AB, BC, CD, AD.

Since opposite sides are equal then:

AB = CD

BC = AD

The perimeter of a parallelogram is the sum of all its sides.

In the question: BC=13 and AB=5

Hence,

AB = CD = 5

BC = AD = 13

Perimeter of Parallelogram ABCD = 5 + 5 + 13 + 13

= 36.

Consider the following data on the estimated cost (in millions of dollars) resulting from traffic congestion for different urban

IrinaK [193]

The mean is $5.769 million and the standard deviation is $3.905 million.

The mean is the average of a data set.

<h3>What is the standard deviation?</h3>

The standard deviation shows the measure of the dispersion from the mean.

<h3>Data and Calculations:</h3>

The sum of two numbers I'd 16. Three times the larger number decreased by the smaller is 72. Find the number

maksim [4K]

Answer:

22, -6

Step-by-step explanation:

Create a system of equations.

x= the larger number

y=the smaller number

Using what you know, create the equations:

x+y=16

3x-y=72

Now add the two equations together. (elimination method)

x+y=16

+ 3x-y=72 (the y's cancel out)

-----------------

4x = 88 Divide.

x = 22

Now plug in x=22 into one of your equations to solve for y.

x+y=16

22+y=16

y=-6

The numbers are 22 and -6.
