Answer:
of favourable events = 4, (which includes 1, 4, 9, 16). And, total number of observations are 20. So, the probability of picking a square number between 1 and 20 is 1/5.
Step-by-step explanation:
your answer would be a because the question was be of the blue prism 418 square units the area of the base B of the red prism is half that of blue. a would be right the height of the red prism is half of the height of blue
C=2•pi•r because C= pi•d and d=2•r
Answer:
We find 3/4-5/24 = 0.54166666666 and try 2/7 x 6/8 = 0.21428571428
this is 0.069 too much we look at this as a fraction = 0.07 which is 1/10 approx of the 6/8. we then reapply 7/9 x 2/7 x 3/3 = 0.2
So we went up by 1 and can show another
2/7 x 7/10 = 2.0
So to 1dp there is lots of fractions including 2/7 x 7/9 = 2.0
But for three fractions that multiply together we can chose 5/7 x 2/6 x 6/6 = 2.0 As 5 x 2 x 6 = 60 and 60/360-102 = 60/258 = 0.20 and divided 198 =numbers 8 and 1/3 work with = 1.98/8.3 = 2.38554
We try again 1.68/8.3 = -0.2024 = 2/8 x 8/10 = 0.2
The balance is 1.3/2 x 0.8/2 = 0.65 x 0.333 = 13/20 x 1/3
3/5 x 1/3 = 0.2
