Suppose that a box contains 30 blue blocks and 20 yellow blocks, and we randomly pick 5 blocks fromthe box. Let X be the random variable denoting the number of blue blocks that are picked. Consider thefollowing two situations:(a) We choose the 5 blocks with replacement.(i) Does X follow a Binomial or a Hypergeometric distribution?(ii) What is the probability mass function (PMF) for X?(iii) What is the Expected value, Variance, and Standard deviation of X?(b) We choose the 5 blocks without replacement.(i) Does X follow a Binomial or a Hypergeometric distribution?(ii) What is the probability mass function (PMF) for X?(iii) What is the Expected value, Variance, and Standard deviation of X?

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier

answer: the is put the 450

step-by-step explanation:
