Answer:

mean: 13

range: 15

there is no mode

median: 13.5

Step-by-step explanation:

mean= 14+9+20+5+17+13 = 78

78÷6= 13

range = highest number minus the smallest number

20-5 = 15

the mode is the number that occurs the most

median= 13+14= 27

27÷2 = 13.5

Phantasy [73]

Answer:

The answer as a mixed number is =15\frac{3}{4}.

Step-by-step explanation:

Given:

5 1/4 ÷ 1/3.

Now, to solve as a mixed number in simplest form.

5\frac{1}{4} \div \frac{1}{3}

<em>Now, changing the mixed fraction into improper:</em>

=\frac{21}{4} \div \frac{1}{3}

So, to solve we change the division into multiplication.

Thus, R.H.S of the fraction will get reverse:

=\frac{21}{4} \times \frac{3}{1}

=\frac{63}{4}

<em>Now, changing the improper fraction into mixed:</em>

=15\frac{3}{4} .

Therefore, the answer as a mixed number is =15\frac{3}{4} .

Which is an equation of the line with slope -3 and passes through (2,-1)?
Lisa [10]
Using the equation
(y-y1) = m(x-x1)
Where x1 and y1 are points that lie on the line and m is the slope.
These, be plugging in the values given, we get
(y-(-1))=(-3)(x-2)
(y+1)=(-3x+6)
