Answer:

<h2>7</h2>

Step-by-step explanation:

Use PEMDAS:

P Parentheses first

E Exponents

MD Multiplication and Division

AS Addition and Subtraction

6:(-3)-(-9)           <em>first - division</em>

=-2+9          <em>use commutative property a + b = b + a</em>

=9+(-2)=9-2=7

A hiking trail is 20 kilometers long. Park organizers want to build 5 rest stops for hikers with one on each end of the trail an
ValentinkaMS [17]

Answer:

There will be 5 kilometers between each rest stop

Step-by-step explanation:

Ok, so there are two rest stops at the start and end of the trail. This means that the sum of the distances of the rest stops must equal 20 kilometers.

If you can imagine a number line being split by 3 lines, it makes four segments.

We can't solve this using 3D = 20 because that would mean one of the three rest stops is at the end of the hike

So,

4D = 20\\D = 5\\

Question 3
Yuliya22 [10]

Answer:

Median and Mode.

Step-by-step explanation:

The data could be represented in table form in ascending order as:

 <u>Number of meals</u>                      <u> Frequency</u>

      2                                                     2

       3                                                     3

       4                                                     2

       19                                                    1`

On the basis of the data now we find the mean, median and mode:

Mean= average of the data

Mean=\dfrac{2\times 2+3\times 3+4\times 2+19\times 1}{2+3+2+1}=\dfrac{40}{8}=5

Hence mean is 5.

Median is the central tendency of the data

on looking at our data we see that the Median=3.

also the mode of the data is the entry corresponding to the highest entry.

Hence the highest frequency is 3 and the corresponding value is 3.

Hence, Mode=3

Hence, the most appropriate measure of center for this situation is :

Median and Mode.

S(t)=9t-4, find S(4)
melamori03 [73]
For this problem, you need to substitute 4 in for your variable t. the original equation is S(t) and the one you need is S(4) -- in other words, evaluate this equation when t = 4.

S(4) = 9(4) - 4
S(4) = 36 - 4
S(4) = 32 is your answer.
