Answer:
Interest Chaney earns after 3 years is $56.85
Step-by-step explanation:
Given:
Amount deposited = $1435.73
Simple annual interest rate = 1.32% = 1.32/ 100 = 0.0132
To find: Interest after 3 years
We know that the formula to calculate the interest amount is
Simple interest (S.I.) = 
where,
P is the initial amount deposited
r is the rate of simple interest in percentage
t is the time in years for which interest is to be calculated
Substituting the known values in the formula, we get
S.I = 
= 56.85
Hence the interest Chaney earns after 3 years is $56.85
Answer:
New mean length of these 17 people=11.62
Step-by-step explanation:
<em>Step 1: Determine the total length of children's fingers</em>
L=l×n
where;
L=total length (cm)
l=mean length (cm)
n=number of children
replacing;
L=6.7×6=40.2 cm
The total children's fingers length=40.2 cm
<em>Step 2: Determine the total length of adults fingers</em>
total length of adults fingers=mean length of adults fingers×number of adults
where;
mean length of adults=14.3
number of adults=11
replacing;
total length of adults fingers=(14.3×11)=157.3 cm
<em>Step 3: Determine the new mean length</em>
new mean length=total length of adults and children fingers/number of adults and children
where;
total length of adults and children fingers=157.3+40.2=197.5 cm
number of adults and children=11+6=17
replacing;
new mean length=197.5/17=11.62
