How to do the estimation
Step-by-step explanation:
He can use the probability of how many people chose English and multiply by 9.7 since there are 970 people / 100 people who asked = 9.7
S (3, 0)
C (5, 1)
W (4, -4)
Explanation
You take the first number and add 6 to it and you get the new number and then you take the second number and subtract 3 from it
S: -3 + 6 = 3
S- 3 - 3 = 0
C: -1 + 6 = 5
C: 4 - 3 = 1
W: -2 + 6 = 4
W: -1 - 3 = -4
Answer:
A 100 lb person will weight 40 lb on Mars
Step-by-step explanation:
Given:
Weight on Mars directly varies as its weight on earth.
Let weight on Mars be =
Let weight on Earth be =
Its known that:
∝
Thus
where is constant of proportionality.
when , then
thus, we have
dividing both sides by 95.
∴
Thus when , would be calculated as
∴ (Answer)
∴ A 100 lb person will weight 40 lb on Mars.
