Step-by-step explanation:
a)i) perimeter= side+side+side+side
perimeter=8.7+8.7+5.4+5.4=28.2cm
ii) area=h×b
area=8.7×5.4=46.98cm²
b)i) perimeter=20.35+20.35+17.84+17.84
perimeter=76.38cm
ii)area=20.35×17.84
area=363.044cm²
c) area of rectangular field=937.125m²
Length=36.75m
i)Breadth=937.125÷36.75=25.5m
ii)perimeter=36.75+36.75+25.5+25.5
perimeter=124.5m

Answer:
Step-by-step explanation:
Given that in an experiment, a number cube is rolled 4 times. The number of times a 5 shows is recorded. Sixty trials of the experiment are run.
No of 5's Freq Prob
0 6 0.1
1 9 0.15
0 33 0.55
3 3 0.05
4 9 0.15
60 1
The above is the probability distribution of the discrete variable.
Answer:
114
Step-by-step explanation:
Supplementary means that all the angles in your givens add up to 180 degrees.
Givens
<A + <B = 180
<A = 2x + 6
<B = x + 3
Solution
<A + <B = 180 Substitute for <A and <B
2x + 6 + x + 3 = 180 Combine like terms on the left.
3x + 9 = 180 Subtract 9 from both sides
3x = 180 - 9
3x = 171 Divide by 3
x = 171/3
x = 57
That's not your answer.
<A = 2x + 6
<A = 2*57
<A = 114
