In an area of the midwest, records were kept on the relationship between the rainfall (in inches) and the yield of wheat
(bushels per acre). construct a 95% prediction interval for y, the yield, given x = 11 inches, =4.379x + 4 267 and
3.529. round interval to two decimal places.

good for u

step-by-step explanation:

its not b

step-by-step explanation:

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
