Answer:
82 kg
Step-by-step explanation:
To find the mean of a set of values, we must add them up and divide by the number of values.
Step 1, adding the values:
Step 2, dividing by the # of terms:
There are 9 terms in total.
To the nearest kilogram, we can round 81.556 into 82.
The mean mass of the 9 men was 
kg.

Answer:
16(4b - c)
Explanation:
16 x 4b = 64b
16 x c = 16c
Answer:
Final answer is 
and 
.
Step-by-step explanation:
Given equation is 
Now we need to find the solution of in given interval ![[0, 2\pi ]](https://tex.z-dn.net/?f=%5B0%2C%202%5Cpi%20%5D)
.
which gives and in the given interval.
Hence final answer is and .
Based on the coordinates of triangle RST, we can infer that triangle RST is <u>not a right-angled triangle. </u>
<h3>Is triangle RST a right-angled triangle?</h3>
For this to be a right-angled triangle, the Pythagoras theorem has to apply where:
Largest side² = Side A² + Side B²
Lengths of the triangle:
RS² = (4 - 2)² + (4 - 3)²
= 5
ST² = (5 - 4)² + (0 - 9)²
= 17
TR² = (2 - 5)² + (3 - 0)²
= 18
We can see that:
18 ≠ 17 + 5
This is therefore not a right-angled triangle.
