Answer:
Step-by-step explanation:
Given that a person’s body surface area (BSA) (in meters squared) using the formula
We are to calculate the rate of change of BSA with respect to mass for a person of constant height h = 180 from m =70 to m =80
For this we calculate BSA for 80 kg and BSA for 70 kg first
Rate of change =
=
i.e. rate of change per 10 kg is 0.129
No BSA does not increase more rapidly
Answer:
D. 0.53
Step-by-step explanation:
Answer:
The new mean for the exam scores is 51
Step-by-step explanation:
the mean can be calculated using the formula
mean of scores =
before the 20 points was added, the mean of the score was = 50.
Inserting this into the formula, we have:
50 =
from this, we can compute the sum total of the scores as
sum total = 50 × 20 = 1000
when the extra 20 marks is added, the sum of the entire scores will be changed to 1000 + 20 = 1020.
Hence the new mean will be computed as (New Sum total of scores / Number of students)
= = 51.
∴ The new mean of the scores is = 51
