Consider the formula w=fd, where
• w represents work
• f represents force and has units of newtonsand
•d represents distance and has units of meters (m),
select an appropriate measurement unit for work.
plz look at pic

Option B

Step-by-step explanation:

we know that

The formula to calculate the work is equal to

where

W represents work

F represents force

d represents distance

The units are

---> Newtons

---> meters

substitute the units in the formula

Remember that when multiply exponents with the same base, adds the exponents and maintain the same base

so

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.
