Step-by-step explanation:
add all of them and then see if they right
There are four scores.
So to find the mean or average, you add all four scores and then divide by 4.
I get 119, then divide by 4, to get 29 and 3/4 or 29.75.
Answer:
<em>Perimeter = 20.6cm to 1dp = 20.60cm to 2dp</em>
<em>Area = Base = 8.6/2 = 4.3 x 4.069 = 17.5cm^2</em>
<em>Height is found 4.07 cos( 54.47deg) 5/8.6 = 4.069cm</em>
Step-by-step explanation:
<em>Right angle side triangle, sides </em>
<em>= MN =8.6cm </em>
<em>= NP=5cm </em>
<em>= PM=7cm </em>
<em>= 25sq + 49sq = 74sq</em>
<em>MN^2 =√74 = 8.60232526704 = 8.6cm</em>
<em>P = 8.6 + 5 + 7 = 20.6cm </em>
4.6 turned into a fraction is 4 6/10= 4 3/5
4.6= 4 3/5.
4 3/5 is simplified.
