Clare estimates that her brother is 4 feet tall. When they get measured at the doctor’s office, her brother’s actual height is 4

Oduvanchick [21]

Percentage of error by Clare is estimated as 4.1667 %

Height measured by Clare = 4 feet

Height measured by Doctor = 4 feet, 2 inches

Percentage error = ?

Percentage error = Difference/ Actual height *100

Percentage error = (2/ (4*12))*100

Percentage error = 4.1667 %

The accurate height is measured by Doctor, as he have more accurate measurement system.

Answer:

$20,475\ ways$

Step-by-step explanation:

we know that

<u><em>Combinations</em></u> are a way to calculate the total outcomes of an event where order of the outcomes does not matter.

To calculate combinations, we will use the formula

$C(n,r)=\frac{n!}{r!(n-r)!}$

where

n represents the total number of items

r represents the number of items being chosen at a time.

In this problem

$n=28\\r=4$

substitute

$C(28,4)=\frac{28!}{4!(28-4)!}\\\\C(28,4)=\frac{28!}{4!(24)!}$

simplify

$C(28,4)=\frac{(28)(27)(26)(25)(24!)}{4!(24)!}$

$C(28,4)=\frac{(28)(27)(26)(25)}{(4)(3)(2)(1)}$

$C(28,4)=20,475\ ways$
