A) it is left skewed
B) the median is 5
C) the mean is 5.15
D) the mean would be more affected (a change of 1.05 versus a change of 0.5).

The majority of the data is to the right of the graph; this means it is left skewed.

To find the median, write all of the data values out:
2, 3, 4, 4, 5, 5, 5, 6, 6, 6, 7, 7, 7

The middle value is 5.

We find the sum of this set of values and divide by 13, the number of data points, to find the mean:
2+3+4+4+5+5+5+6+6+6+7+7+7 = 67/13 = 5.15

If we added an additional data value at 20, the new median would be 5.5. The new mean would be (67+20)/14 = 6.2. The mean changes more than the median.

3/4 x = -12 <br>Please help

kozerog [31]

Answer:

$x = - 16$

Step-by-step explanation:

Let's solve:

$\frac{3}{4} x = - 12$

Step 1: Multiply both sides by 4/3.

$( \frac{4}{3} )*( \frac{3}{4} x)=( \frac{4}{3} )*(−12)$

$x = - 16$

I set off on a 15 miles cycle ride at a speed of 10mile per hour. how long does the ride take me

PolarNik [594]

The ride takes 1.5 hours for a speed of 10 miles per hour.

<h3>What is speed?</h3>

The rate at which an object travels a certain distance can be described using the speed formula. The distance that a body travels in a certain amount of time is a common way to measure speed.

A body's speed can be defined as how quickly it is going. The equation for a given body's speed can be written as,

Speed=Distance/Time

According to the question,

Speed=10 miles per hour

Distance=15 miles

Time= $\frac{15}{10}$ =1.5 hours
