The mean length (rounded to 2 DP) of these 8 people's index finger is 5.83
<h3>What is the mean length (rounded to 2 DP) of these 8 people's index finger?</h3>
The given parameters are:
<u>Children</u>
Mean = 5.6 cm
Frequency = 5
<u>Adult</u>
Mean = 6.2 cm
Frequency = 3
The mean length of these 8 people's index finger is calculated as:

So, we have
Mean = (5.6 * 5 + 6.2 * 3)/(5 + 3)
Evaluate
Mean = 5.83
Hence, the mean length (rounded to 2 DP) of these 8 people's index finger is 5.83

Answer:
5s⁷/6
s⁵
3r⁴s⁵
-r⁴s⁶
-6rs⁵
4r/5⁶ can't be the first term.
We start with the highest degree term
It is -4/9 because the slope is the same when lines are parallel. The y is what is different in the equation
We want to find the slope-intercept equation of the line passing through (-2,-5) with a slope of 0.
Note that since the slope is 0, the line will be horizontal, as there will be no change.
And since it passes through the point (-2,-5), the equation of the horizontal line must be y = -5. Since the line is horizontal, the x-coordinate is irrelevant.
In conclusion, our equation is y = -5.
