5 0

Answer:

yes

Step-by-step explanation:

A rational number can be expressed in the form

\frac{a}{b} ← where a, b are integers

Given

\frac{6}{1.2} ← multiply numerator/ denominator by 10

= \frac{60}{12} = 5 = \frac{5}{1} ← a rational number

What is the center of the data?
satela [25.4K]

Answer:

Median = 13

Step-by-step explanation:

Given

See attachment for dot plot

Required

The center of data

This implies that, we calculate the median

From the attached plot,

n = 13 --- number of observation

So, the median is:

Median = \frac{n + 1}{2}

Median = \frac{13 + 1}{2}

Median = \frac{14}{2}

Median = 7th

The median is at the 7th position

At the  7th position, is 13

Hence:

Median = 13

A 44<br> B 5<br> C 10<br> D None of the choices are correct.
Brums [2.3K]

Answer:

D. None of the choices are correct.

Step-by-step explanation:

If <em>B</em> is the midpoint of AC, then that means that AB is congruent to BC. Because this is true, you can set 8x + 4 and 10x - 8 equal.

8x + 4 = 10x - 8

Now just solve for x. Subtract 8x from both sides and add 8 to both sides.

4 = 2x - 8

12 = 2x

Then divide by 2.

6 = x

Another way to do this problem is to set up the same equation, but instead of solving it, plug in answer choices A, B, and C independently of each other. Then simplify to see if those are right. You'll find out that none of them are.
