using a formula estimate the body surface area of a person whose height is 5 feet and who weighs 120 pounds.
a.
1.52 m2
b.
0.32 m2
c.
1.13 m2
d.
55.9 m2

(A)  1.52 m²

Step-by-step explanation:

As per the given data of the question,

Height of a person = 5 feet

As we know that 1 feet = 30.48 cm

∴ Height = 152.4 cm

Weight of a person = 120 pounds

And we know that 1 pound = 0.453592 kg

∴ Weight = 54.4311 kg

The Mosteller formula to calculate body surface area (BSA):

Therefore,

Hence, the body surface area of a person =  1.52 m²

Therefore, option (A) is the correct option.

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
