the last one
Step-by-step explanation:
<span>When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:1) Square all 3 sides.36, 27, 61

3) Compare this sum to the square of the 3rd side.2,025 < 3,721
if sum > 3rd side² Acute Triangleif sum = 3rd side² Right Triangleif sum < 3rd side² Obtuse TriangleTherefore, it is an Obtuse TriangleSource:http://www.1728.org/triantest.htm

This is the concept of proportionality, given that z is directly proportional to x and inversely proportional to y then:
zαx/y
z=(kx)/y
where;
k is the constant of proportionality given by:
k=zy/x
but when x=3 and =6 then z=9.5
therefore:
k=(9.5*6)/3
k=19
hence the formula for z will be:
z=(19x)/y
the value of z when x=8 and y=12 will be:
z=(19*8)/12
z=12 2/3
Answer:
Step-by-step explanation:
<u>Given scores:</u>
<u>Mean of the scores:</u>
- (15 + 25 + 10 + 2 + 8)/5 = 12
<u>Absolute deviations:</u>
- |15 - 12|= 3
- |25 - 12|= 13
- |10 - 12| = 2
- |2 - 12| = 10
- |8 - 12| = 4
<u>Sum of absolute deviations:</u>
<u>Mean absolute deviation:</u>
