So, to do this, all you need to do is add up all the values, and then, with that number, divide by how many values are given.

150+165+165= 480
480/3= 160

Answer:

Minimum = 14

Q_1=23

Median = 32

Q_3=49

Maximum = 65

Step-by-step explanation:

<u>Step 1: </u>Put your numbers in ascending order (from smallest to largest). For this particular data set, the order is

14, 18, 28, 29, 32, 44, 48, 50, 65

<u>Step 2:</u> Find the minimum and maximum for your data set. Now that your numbers are in order, this should be easy to spot.

Minimum = 14

Maximum = 65

<u>Step 3: </u>Find the median. The median is the middle number. The middle number in your list is 32, so

Median = 32

<u>Step 4: </u>Place parentheses around the numbers above and below the median.

(14, 18, 28, 29), 32, (44, 48, 50, 65)

<u>Step 5: </u>Find Q1 and Q3. Q1 can be thought of as a median in the lower half of the data, and Q3 can be thought of as a median for the upper half of data.

First quartile

\bf{Q_1=\dfrac{18+28}{2}=\dfrac{46}{2}=23}

Third quartile

\bf{Q_3=\dfrac{48+50}{2}=\dfrac{98}{2}=49}

<u>Step 6:</u> Write down your summary found in the above steps.

Minimum = 14

Q_1=23

Median = 32

Q_3=49

Maximum = 65

I need hellllppp plsssss​
bagirrra123 [75]

Answer:

a_7=-15

Step-by-step explanation:

a_n  is given as the nth term of a sequence.

We want to find a_7 , which means we find the 7th term of the sequence.

Here, we simply substitute "7" into "n" of the formula given for  a_n  to find the value of the 7th term of the sequence.

We show this below:

a_n=-3(n-2)\\a_7=-3(7-2)\\a_7=-3(5)\\a_7=-15

So the 7th term is "-15"
