Two forces, (4i – 5j) N and (pi + qj) N, act on a particle P of mass m kg. The resultant of the two forces is R. Given that R acts in a direction which is parallel to the vector (i – 2j), (a) Find the angle between R and the vector j.
(b) Showthat2p+q+3=0.
Given also that q = 1 and that P moves with an acceleration of magnitude 8√5 ms-2;
(c) Find the value of m.
Can anyone please give me ..

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
