Alejandro wants to determine the average shoe size of all of the male students in his school. which sample is likely to yield the most biased results? every tenth boy on the school’s phone list every member of the boys’ basketball team every boy in a randomly selected ninth-, tenth-, eleventh-, and twelfth-grade gym class every fifth boy who walks through the front doors of the school in the morning

The correct answer is:

every member of the boys’ basketball team

Explanation:

Members of a basketball team are typically taller than other people. Taller people generally have larger feet, and larger shoe sizes, than shorter people. Choosing only people from this area would be a biased sample.

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°
