Answer:
25%
Step-by-step explanation:
This question is about conditional probability. Let's say that the probability of raining on Saturday is X=true and the probability of raining on Sunday is Y=true. There is a 15% it will rain on both Saturday and Sunday, to put into the equation it will be:
P(X= true ∩ Y = true) = P(X = true) * P(Y = true)= 0.15
There is a 60% chance of rain on Saturday, mean the equation is
P(X = true) = 0.6
The question is asking for the chance of rain on Sunday or P(Y = true). If we substitute the second equation to first, it will be:
P(X = true) * P(Y = true)= 0.15
0.6* P(Y = true)= 0.15
P(Y = true)= 0.15/0.6
P(Y = true)= 0.25 = 25%
25% chance or 4/6 that is probablility
Answer: Choice B
=============================================
Explanation:
The endpoint is at 4.5 and this endpoint is a filled in circle. So we'll have "or equal to" as part of the inequality sign. This is because we are including the endpoint as part of the shaded solution region.
The other part of the inequality sign is "less than" because the shading is to the left of the endpoint. Any point in the shaded region is less than 4.5, or it could be equal to 4.5
Put another way: x is either 4.5 or smaller
We write that as which is read out as "x is less than or equal to 4.5"
Surrounding this in curly braces tells the reader we're dealing with a set of values. The first part "x |" means "x such that"
All together we end up with the answer which translates to "x such that x is less than or equal to 4.5"
Answer:
It will take 4 years to deplete the account.
Step-by-step explanation:
Prudential Reality has an escrow account that contains $20,000.
The client withdraws $5000 now and that leaves $15000.
After one year an amount of $4500 is withdrawn which leaves ($15000 - $4500) = $10500
After two years an amount of $4000 is withdrawn which leaves ( $10500 -$4000) = $6500.
After three years an amount of $3500 is withdrawn which leaves ( $6500 - $3500) = $3000
After four years an amount of $3000 is withdrawn which leaves ($3000 - $3000) = $0 in the account.
Hence it will take 4 years to deplete the account.
