Step-by-step explanation:
F(x)=2x²+5√(x-2)
f(3)=2(3)²+5√(3-2)
= 2 (9) + 5√1
= 18 + 5
= 23.
Answer:
1/5
Step-by-step explanation:
Range as a measure of central tendency is the difference between the highest value and the lowest value in a given set of data.
Given the samples 0,1,3,4,7
Total number of samples is 5
The range is gotten by taking the difference of 2 samplesout of 5samples and this can be done in 5C2 ways.
5C2 = 5!/(5-2)!2!
= 5!/3!2!
= 5×4×3!/3!×2
= 10ways
The total outcome is therefore 10
To get the probability that the range is 4, we need to get the required outcome of getting range of 4 and this can only occur twice
The range can be gotten by taking the difference between 7 and 3, it can also be gotten by taking the difference between 4 and 0. Both differences will give us a total of 4
The expected outcome is therefore 2
the probability that the range of the sample is 4 = expected outcome/total outcome
= 2/10
= 1/5
Answer:
steps below
Step-by-step explanation:
(a) first green: 8/23 AND 2nd green: 7/22
AND: multiplication.. 8/23 x 7/22 = 28/253 ≈ 0.11 (11%)
(b) 15/23 x 8/22
Answer:
35 inches long
Step-by-step explanation:
the answer is 35 inches long because if you do 38x2 because of the two sides you will get 76 then subtract 76 from 146 then you will get 70. Then do 70÷2 to find out the other side and i got 35
