The common ratio for the geometric sequence is :
<span>32</span>

Explanation:

<span>16,24,36,54</span>

We calculate the common ratio r:
r is obtained by dividing a term by its preceding term

1) <span><span>2416</span>=<span>32</span></span>

2) <span><span>3624</span>=<span>32</span></span>

The common ratio for the geometric sequence is :

Answer:  The required common ratio of the given geometric sequence is \dfrac{3}{2}.

Step-by-step explanation:  We are given to find the common ratio of the following geometric sequence :

16,   24,   36,   54,   .   .   .

We know that

the common ratio of a geometric sequence is the ratio of any term to its preceding term.

For the given sequence, we have

a(1) = 16,   a(2) = 24,  a(3) = 36,  a(4) = 54,  .  .  .

So, we get

\dfrac{a(2)}{a(1)}=\dfrac{24}{16}=\dfrac{3}{2},\\\\\\\dfrac{a(3)}{a(2)}=\dfrac{36}{24}=\dfrac{3}{2},\\\\\\\dfrac{a(4)}{a(3)}=\dfrac{54}{36}=\dfrac{3}{2},~~.~~.~~.

Thus, the required common ratio of the given geometric sequence is \dfrac{3}{2}.

Why is a regression line referred to as the line of best fit?
aalyn [17]
<h2>Answer with explanation:</h2>

When there is a linear relationship is observed between the variables, we use  linear regression predict the relationship between them.

Also, we predict the values for dependent variable by modelling a linear model that best fits the data by drawing a line Y=a+bX, where X is the explanatory variable and Y is the dependent variable.

In other words: The line of best fit is a line through a scatter plot of data points that best describes the relationship between them.

That's why the  regression line referred to as the line of best fit.

The range of three numbers is 17.the mode is 24 and the median is 24 ? What are the three numbers?
vivado [14]

The answer is 7, 24, 24.

The median is the middle number.

The mode is the number which occurs the most.

The range is the difference between the largest number and the smallest number.

Since 24 is the middle number, it is the median.

Since 24 is also the number which occurs the most often, it is also the mode.

To find range, do 24-7 which is equal to seventeen.
