Answer:
The mechanical advantage is 0.25
This mechanical advantage shows that the force at which the deodorant sprays is the quarter of the applied effort, and hence the efficiency of your finger as a machine is 25%.
Explanation:
Given;
output force, F₂ = 15 N
input force, F₁ = 60 N
Mechanical advantage also known as force ratio is defined as the ratio of the output force (load) to the ratio of input force (effort).

This shows that the force at which the deodorant sprays is the quarter of the applied effort, and hence the efficiency of your finger as a machine is 25%.

Answer:
You will need to implement a for loop ( I am assuming this is java)
Explanation:
int count20s = 0;
for(int x =0; x< customerAges.length;x++){
if(20 <= customerAges[x] && customerAges[x] <= 29){
count20s++;
}
