Answer:
a) 0.0567
b) 0.4717
c) 0.099057
Step-by-step explanation:
Given:
P( population are 64 or over ) = 21% = 0.21
P( Population are under 64 ) = 1 - P( population are 64 or over )
= 1 - 0.21 = 0.79
P( 64 or over have loans ) = 27% = 0.27
P( under 64 have loans ) = 52% = 0.52
Now,
a) P( 64 or over and has a loan )
= P( 64 or over have loans ) × P( population are 64 or over )
= 0.27 × 0.21
= 0.0567
b) P( Has a loan )
= P( population are 64 or over ) × P( 64 or over have loans ) + P( Population are under 64 ) × P( under 64 have loans )
= ( 0.21 × 0.27 ) + ( 0.79 × 0.52 )
= 0.0609 + 0.4108
= 0.4717
c) P( events that person is 64 or over and that the person has a loan independent )
= P( population are 64 or over ) × P( Has a loan )
= 0.21 × 0.4717
= 0.099057
3 + 5 = 8
40/8 = 5
5 x 5 = 25 girls
Assuming simple interest
I=PRT
P=principil
r=rate
t=time in years
I=interst
9months to years
12months per year
9/12=3/4 year
t=0.75
I=300*0.055*00.75
I=123.75
interest is $1.23.75
Answer:
Step-by-step explanation:
Given that:
Tip left = $1.30
Tax = 7%
Tip = 10% of after tax cost
The tax percentage is not needed in calculating the bill after tax and tip
Hence,
Let after tax cost = x
10% of x = 1.30
0.1x = 1.30
x = $13
After tax cost = $13
Hence, the Total bill after tax = $13
