I hope this helps,
So is she can run 3/4 if a mile , or .75, in nine minutes I simplify just divided nine with 3/4 , or .75 I changed it to make it easier , and I got 9÷0.75= 12mph.
I hope this helps in some way.

The dot plot represents the length of practice time in minutes for the math competition. Explain how the outlier of the data aff

lidiya [134]

Using statistical concepts, it is found that:

The mean practice time decreases because of the outlier.

The median practice time does not change because of the outlier.

The range increases because of the oulier.

<h3>What are the mean, the median and the range of a data-set?</h3>

The mean is the sum of all observations divided by the number of observations.

The median is the middle value, the value that separates the upper 50% from the bottom 50%.

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

From their concepts above, we have that the mean and the range are influenced by outliers.

In this problem, the outlier is at the low end, of 15, hence:

The mean practice time decreases because of the outlier.

The median practice time does not change because of the outlier.

The range increases because of the oulier.

Help me ASAP!!!!!!!!

larisa [96]

Step-by-step explanation:

a) The rule is multiply the previous term by 6 then add 13. So if the 1st term is n0 = -2, then the next term n1 is

n1 = 6n0 + 13

= 6(-2) + 13

= 1

n2 = 6n1 + 13

= 6(1) + 13

= 19

So the sequence goes like

-2, 1, 19

b) Now the sequence is reversed so let's write the terms as follows:

19, 1, -2

The new rule now is subtract 13 then divide by 6. You can check this as follows:

n0 = 19

n1 = (n0 - 13)/6

= (19 - 13)/6

= 1

n2 = (n1 - 13)/6

= (1 - 13)/6

= -2

The first terms of a geometric sequence are as follows.

Flauer [41]

The fourth and fifth term of this sequence is -30 and -10 respectively.

Data;

first term (a) = -810
common difference (r) = ?

<h3>Common Difference</h3>

The common difference in a geometric progression is the ratio between two successive terms.

Let's find the common difference in this sequence

$r = \frac{-270}{-810} \\r = \frac{1}{3}$

The nth term of a geometric sequence is given as

$T_n = ar^n^-^1\\$

The next two terms of this sequence will be 4th and 5th term.

The fourth term of this sequence is

$T_4 = ar^4^-^1\\T_4 = -810 * (\frac{1}{3})^3\\ T_4 = -810 * \frac{1}{27}\\ T_4 = -30$

The fifth term of this sequence is

$T_5 = ar^5^-^1\\T_5 = -810 * (\frac{1}{3})^4\\T_5 = -810 * \frac{1}{81} \\T_5 = -10$

The fourth and fifth term of this sequence is -30 and -10 respectively.
