5X+7 is the correct answer
Answer:
ok so it would take more effort to lift the 1 newton that is 4 m
Step-by-step explanation:
Work is done when a an object with a certain weight is moved at a given distance;
It is the product of force and distance and therefore varies directly to both distance and force.
Work = Force × distance;
For a 4 N box 0.5 m;
Work = 4 × 0.5
= 2 Joules
For a 1 N box 4 m
Work = 1 × 4
= 4 Joules
Therefore, Lifting a 1 N box for 4 m, will take more work
hope this helps

Answer:
The sample size must be approximately 211.
Step-by-step explanation:
We are given the following in the question:
Sample mean, = 654.1
Alpha, α = 0.02
Population standard deviation, σ = 311.7
Margin of error = 50
Formula:
Putting all the values, we get,
Thus, the sample size must be approximately 211.
