Let X denote the number of Canon digital cameras sold during a particular week by a certain store. The pmf of X is as follows x 01 2 3 4 Px(x) 0.1 0.2 0.3 0.16 0.24 The probability that a particular customer buys an extended warranty given they purchase a camera is 0.60. Let Y denote the number of purchasers during this week who buy an extended warranty. (Give answers accurate to 3 decimal places.) (a) What is P(X-4, Y- 2)?
(b) Determine the joint pmf of X and Y.
(c) Determine the marginal pmf of Y P(y)
(d) Calculate P(X Y)

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

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested
