Answer:
The likelihood that he or she has a pet given that a student does not have a sibling is:
Option: D ( 60%)
Step-by-step explanation:
Let A denote the event that a student does not have a sibling.
Let B denote the event that a students has a pet.
Then A∩B denotes the event that the student does not have a sibling but has a pet.
Let P denote the probability of an event.
Then, we are asked to find:
P(B|A)
We know that:

Also from the table we have:
P(A)=0.25
and P(A∩B)=0.15
Hence,

which in percentage is:

Hence, the likelihood is:
60%
Assuming you're going off of current data, 6.2% of gross pay is taken out for the Social Security tax.
So, simply take the gross pay 2344/100, which equals 23.44, then multiply by the percentage,6.2, to get 145.32
So, $145.32 is deducted from your gross pay.
There. Now you don't even need to find the answer.
y=mx+b
m=slope
b= y intercept (when x = 0
y= y value
x=x value
you already have your slope given plug in you x and y values into the equation and reverse the math, like you would do to "solve for X this time B"
you will then get you whole equation
if you are asking how many are being bought to somewhere all together it is 30.
