Need help to but can you mark Brainily
4t ^ 2 - 16 ÷8 ÷ t - 2 ÷6
=(4t ^ 2)-(16 ÷8 ÷ t)-(2 ÷6)
=(4t ^ 2)-(2/t)-1/3
=4t ^ 2-2/t-1/3
Answer:
Parameter
Step-by-step explanation:
We are given the following in the question:
The average age of men who had walked on the moon was 39 years, 11 months, 15 days.
Population and sample:
- Population is the collection of all observation for variable of interest or individual of interest.
- Sample is a subset for population.
Parameter and statistic:
- Any variable or value describing a population is known as parameter.
- Any value describing a sample is known as statistic.
Population of interest:
men who had walked on the moon
Value:
average age of men who had walked on the moon
Thus, the give value describes a population and hence, it is a parameter.
Answer:
100 J
Step-by-step explanation:
The formula for kinetic energy is as follows:
where
KE= kinetic energy (J)
m= mass (kg)
v= velocity (m/s)
Given: m= 50 kg, v= 2 m/s
Substituting the given information into the formula:
KE
= ½(50)(2²)
= ½(50)(4)
= 100 J
Yes subtracting is taking away from another. 5-3 is two because you take 3 away from 5.
