Step-by-step explanation:
There are four quarter circles, each with radius 9 ft. Together, they form a full circle. There are also four squares, each with side length 9 ft.
A = πr² + 4s²
A = π (9 ft)² + 4 (9 ft)²
A ≈ 578.469 ft²
18% = 0.18
Tip = $36.00 x 0.18 = $6.48
Total bill = $36.00 + $6.48 = $42.48
Answer:
Total bill = $42.48
Tip = $6.48
(4 hundred + 0 tens + 5 ones) + (1 ten) = 4 hundred + 1 ten + 5 ones
... = 415
Answer:
Approximate probability that 
is less than 2 = 0.1515
Step-by-step explanation:
Given -
Mean 
= 2.2
Standard deviation 
= 1.4
Sample size ( n ) = 52
Let be the mean of accidents per week at the intersection during one year (52 weeks) .
probability that is less than 2 =
= 
Putting 
= 
( Using Z table )
= 0.1515
