We gots a squrae and 1/4 circle
circle=pir²
square=side²
side=r=8
so
area=8²+(1/4)pi8²
area=64+(1/4)pi64
aer=64+16pi
area=64+50.24
area=114.24 cm²
2nd option
Answer: here is the simplify version −642+321i
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
60% of 24 need to complete their tasks
this is 6x2.4=12+1.6=13.6 =14
Step-by-step explanation:
consider k the numbe of correct answers
P(k) = kC8×(0,2)^k×(0,8)^(8-k)
example:
The probability of having 2 correct answers = 2C8×(0,2)^2×(0,8)^(6) = 0.294
the probability that the number x or correct answer is fewer than 4 =
p(0) + p(1) + p(2) + p(3) = 0.944
