OK the answer is 9.055 but If you choose to round just put 9.06 your choice but I would put 9.055
Answer:
...
against the wind, an airplane travels 3640 km in 7 hours.
with the wind, the same plane travels 6000 km in 6hrs.
...
let speed of plane in still air be x mph
speed of wind be y mph.
..
t=d/r
..
against wind speed = x-y mph
with wond speed = x=y mph
...
3640/(x-y)=7
3640 = 7x-7y
/7
520=x-y.....................1
...
6000/x+y = 6
6000 = 6x+6y
/6
1000=x+y.....................2
...
Add (1) & (2)
2x=1520
/2
x=760 mph speed of plane in still air
...
plug value of x in 2
1000=760+y
100-760=y
240 = y
240 mph speed of wind

Create a dot plot of the data shown below. 20, 21, 21, 25, 20, 23, 27, 23, 24, 25, 26, 24, 23, 22, 24 Which measure of center wo
JulijaS [17]
The measure of center that would best describe a typical value of the data set is a mean since the values are close.
<h3>What is a measure of center?</h3>
It should be noted that the measure of center include the mean, median, mode, and the mid-range.
In this case, when there is a close distribution of different numbers, he beta measurement will be the mean.
Therefore, the mean of the numbers will be:
= (20 + 21 + 21 + 25 + 20 + 23 + 27 + 23 + 24 + 25 + 26 + 24 + 23 + 22 + 24)/15
= 348/15
= 23.2
