Aschool has 320 girls and 250 boys the probability that a girl is left hand is 0.2 the probability that a boy is left handed is 0.1 estimated number of left-handed students in school

There are 89 left handed students in school.

Step-by-step explanation:

Since we have given that

Total number of girls = 320

Total number of boys = 250

Probability that a girl is left hand = 0.2

Probability that a boy is left handed = 0.1

We need to find the number of left handed students in school.

Similarly,

Hence, there are 25+64=89 left handed students in school.

Correct  a₂ > a₁

Explanation:

Given:

Tony  mass = m₁ = 50 kg

Sam mass = m₂ = 45 kg

According to Newton's second law, the formula for calculating force is:

F = m · a

In this case we have the same force for both

F = m₁ a₁ = m₂ a₂  => a₁ / a₂ = m₂ / m₁ = 45 / 50 = 9 / 10 = 0.9

a₁ = 0.9 a₂  => a₁ = 90% of a₂ => a₂ > a₁

a₂ > a₁
