Find the area of the regular hexagon if the apothem is 8 squared root 3 m and a side is 16 m. Round to the nearest whole number.
Mars2501 [29]
Perimeter = 16 * 6 
Area = (1/2)(perimeter)(apothem)
Area = (1/2) (16 * 6)(8\/3)

3 red balls, 4 white balls, and 1 green ball are in a bag. Balls are drawn without replacement. Find the probability that the re
jolli1 [7]

The probability that the red balls can be drawn before the green ball is drawn is 3/8.

<h3>What is Probability?</h3>

The probability is the measure of the likelihood of an event to happen.

Given:

red balls= 3

white balls = 4

green balls = 1

So, Probability of red balls

=3/8

Probability of green balls

=1/7

Explain why the system has the answer given. Solve each system by elimination to prove your answer.
andrey2020 [161]

Answer:

<em>Proved below</em>

Step-by-step explanation:

<u>System of Equations</u>

There are several ways to solve a system of linear equations. One of the most-used is the method of elimination which consists in adding two or more equations to eliminate one or more variables.

The system shown in the question has evidently no solutions because we have the same variables related in the exact same way in the left side of both equations and a different number as a result of those operations.

To prove the statement, let's multiply the first equation by -1

-x-2y=-8\\x+2y=20

Adding both equations:

0=12

This false result comes from the fact that we tried to solve a system with no solutions. The only way we could have solved it is that both right sides had been equal

The table shows data from a survey about the number of times families eat at restaurants during a week. The families are either
Anna11 [10]

Solution:

1. Rome

Minimum=0

Maximum=16

Q_{1}=3, Q_{3}=13, {\text{IQR}=Q_{3}-Q_{1}=13-3=10,

Median ,Q_{2}=8.5

Mean = 8

Standard Deviation(σ)=5.4

As, difference between , Maximum -Mean =Mean - Minimum=8

So, Mean will Worthy description to find the center of Data set, given about Rome.

2. New York

Minimum=1

Maximum=20

Q_{1}=4.5, Q_{3}=6, {\text{IQR}=Q_{3}-Q_{1}=6-4.5=1.5,

Median ,Q_{2}=5.5

Mean = 7.25

Standard Deviation(σ)=6.1

As, for New york , Mean is not the mid value, that is difference between Mean and Minimum is not same as Maximum and Mean.

As, you can see , the three Quartiles , Q_{1},Q_{2},Q_{3} are very close to each other, it means , other data values are quite apart from each other. So, Mean will not  appropriately describe the given data.So, in this case Median will suitable to find the center.

Option (B): The Rome data center is best described by the mean. The New York data center is best described by the median.
