In a survey of 400 seniors, x percent said that they plan on majoring in physics. one university has used this data to estimate the number of physics majors it expects for its entering class of 3300students. if the university expects 66 physics majors, what is the value of x

Answer ...........> The percentage of student expected to major physics in university is 2%

Explanation:

We are given that 66 students are expected to major physics in university.

We are also given that the total number of students in the university is 3300 students.

Therefore,

estimated % of university students that will be majoring physics = %

Hope this helps :)

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
