Klio2033 [76]
<h3>Answer: B. Graph is nearly symmetrical</h3>

Explanation:

Given information:

  • A number line going from 2 to 11.  
  • 0 dots are above 2.  
  • 0 dots are above 3.  
  • 1 dot is above 4.  
  • 2 dots are above 5.  
  • 4 dots are above 6.  
  • 4 dots are above 7.  
  • 3 dots are above 8.  
  • 2 dots are above 9.  
  • 2 dots are above 10.  
  • 0 dots are above 11.

From that we can see the data set is {4,5,5,6,6,6,6,7,7,7,7,8,8,8,9,9,10,10} which produces the dot plot you see in the image attachment below.

It's a bit tricky to see, but the graph is nearly symmetrical. If we were to remove the blue points in the dot plot I provided, then we'll get a perfectly symmetrical distribution. Symmetrical means one half is a mirror copy of the the other half. The center line of a symmetrical distribution is both the mean and median.

What is a formula for the nth term of the given sequence? 48, 72, 108​
WITCHER [35]

Answer:

a_n=48*1.5^{n-1}

Step-by-step explanation:

<u>Geometric Sequence</u>

In geometric sequences, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.

We are given the sequence:

48, 72, 108, ...

The common ratio is found by dividing the second term by the first term:

r=\frac{72}{48}=1.5

To ensure this is a geometric sequence, we use the ratio just calculated to find the third term a3=72*1.5=108.

Now we are sure this is a geometric sequence, we use the general term formula:

a_n=a_1*r^{n-1}

Where a1=48 and r=1.5

\boxed{a_n=48*1.5^{n-1}}

For example, to find the 5th term:

a_5=48*1.5^{5-1}=48*1.5^{4}=243

The table shows the number of balls, by sport, in the gym.
n200080 [17]
A. The ratio of soccer balls to all balls are 4:25

All the balls combined are 50 balls

8 of the balls are soccer balls so that makes the ration 8:50

In the simplest form it is 4:25 since you can't divide 4 or 8 by 50, you can use 2
and you get 4:25 as your answer
So it is A.
