Answer:
if anyone is looking at this it's warm front is when a warm air mass slides over a cold air mass and stationary front is when a cold air mass and a warm air mass me and do not move and a cold front when a cold air mass slides under a warm air mass and it included front is when two cold fronts force a warm front up and block it from the surface
Multiply both sides by r
Sr=v
divide both sides by s
r=v/s
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
This is a binomial distribution.
p = 0.71, q = 1 - p = 1 - 0.71 = 0.29, n = 20
P(x ≤ 19) =1 - P(x = 20) = 1- 20C20 x (0.71)^(20 - 20) x (0.29)^20 = 1 - 0.29^20 = 1 - 0 = 1
