V=1/2h(a+b)*l
But the numbers in and do the formula and this should give the correct answer
Hope this helps
Plz mark as brainlest if it does! :)
Answer:
it is probaly all 3 yes
Step-by-step explanation:
-3 and -18 are negative numbers and the don't have any values at the end so they are the same
6m and 11m are the same because the both have the same value witch is the 'm'.
Answer:
P(X ≥ 2) = 0.90842
Step-by-step explanation:
This is a Poisson distribution problem
And Poisson distribution formula is given by
P(X = x) = (e^-λ)(λˣ)/x!
where λ = mean = average arrival rate = 4 customers per hour
x = variable whose probability is required = at least 2. P(X ≥ 2)
P(X ≥ 2) = 1 - P(X < 2)
P(X < 2) = P(X=0) + P(X=1)
P(X=0) = (e⁻⁴)(4⁰)/0!
P(X=0) = 0.01832
P(X=1) = (e⁻⁴)(4¹)/1!
P(X=1) = 0.07326
P(X < 2) = P(X=0) + P(X=1) = 0.01832 + 0.07326 = 0.09158
P(X ≥ 2) = 1 - P(X < 2) = 1 - 0.09158 = 0.90842
Hope this Helps!!!
Answer:
Completely Randomized Design
Step-by-step explanation:
In a completely randomized design, the samples are randomly assigned to the treatment without creating any blocks or groups.
Like here, in the given scenario, we do not have to divide subjects in two groups as they are all same.
Whereas, in a randomized block design, the participants are divided into subgroups in a way, that the variability within the blocks is less than the variability between blocks.
After dividing, the participants within each block are randomly assigned to treatment conditions.
Hence, the completely randomized design is used here.
