A.b.Let 𝑋 be a discrete random variable with … (2023)

Find the expected value and variance for each random variable whose probability density function is given. When computing the variance, use formula (5). $$f(x)=5 x^{4}, 0 \leq x \leq 1$$

One radio going to solve a problem but perfects it was doing toe X minus one one. There's been a record that's less than or equal to put expectation off. X is equal to 1 to 2 thanks you do through in the X minus one. The It's the Jessica's one toe two X Square minus Do Eggs Dix, which comes to 1 to 2 two x squared the eggs minus one toe. Two looks the X It comes to be two x Q by three 12 to minus two x squared by two blind people which physicals to into to Cuba. Three. Do we do one que by three minus two square plus one square. It comes to be five by three, then variance off X variance off X physical, too one toe. Take the square into movinto X minus one. The minus. Fight by trader Whole square, one toe to execute the eggs minus. Want to do towards the square The X minus 25 by night, which is to access to four by four. Want to toe minus two X. Q by three one toe minus 25 by nine, which comes to be one bite 18 so he effects equals five by three Variance off X is equal to one by 18. Thank you

Hello, everyone. Today we are going to solve a problem. Number three Yep. F ethics equals one day. Food for one less than a record takes less than a record to fight, so expectation off X is equal to want to fight X in tow one by four The X with physicals one day for into x squared by two. Want to fight, which comes to be by square by eight minus one square by eight Value is three U F X is equal to three variance off X is equal to want to fight X squared daughter one before the X minus three square, which is sickles one by four in the other one to fight excess quality X Milosz Man executed by well Want to fight minus nine It comes to be five killed by 12 minus one que by 12 minus name. It comes to be for by three So e f X is equal to three Where and soft X is equal to four by three. Thank you

Today we're going to solve a problem. Number seven here ffx Because to elect Scinto one minus X, the whole square zero does not. The context does not equal to one. Expectation is equal to into the 0 to 1 eggs in do to elect minus 24 X squared plus dual x cubed the X Well, Intel 0 to 1 ex clarity X minus 24 It was 0 to 1 picks cube. The yes do well in the 0 to 1 existed for the it's, which is equal to for execute 0 to 1 minus six Xs 24 0 to 1 plus well accessed. If I buy fight 0 to 1 but difficult to foreign toe. One cube minus four into zero Q minus 16 to 1 just before plus six into zero. Rested for plus you really do. One goes to fight by fight minus two Will in due the road is 25 by five, which comes to be by faith. Then we need to find ways and soft X variance off X is equal to the road to one eight square daughter to elect minus 24 X square plus well X cubed DX minus Dubai Side, the whole square. So which comes to be like well and 0 to 1 x cubed de Explain US 24 0 to 1. Access to for the X plus well, Intel 0 to 1. Access to fight the X minus four by 25 which is a call to three acceptable by existed for from 0 to 1, minus 24 access defied by five from 0 to 1 plus to exist to six 0 to 1, minus four by 25. So which comes to be like three minus zero, minus 24 by fight zero plus two minus zero minus four by 25 which is a kowtow won by 25 Expectation all fixes one way flight Parents off axis One day 25. Thank you.
