Answer:
4/5
=0.8
explanation
My answer is 0.8 because four less than five and five greatest than four.
So four divide five is equal to zero point eight.
Let
x------> hours worked by Sara last week
y------> hours worked by Joan last week
z------> hours worked by Erin last week
we know that
x=28 hours ------> equation 1
y=x-6-----> equation 2
substitute the value of x in equation 2
y=28-6=22 hours
z=y/2------> equation 3
substitute the value of y in the equation 3
z=22/2=11 hours
<u>the answer is</u>
Sara worked 28 hours last week
Joan worked 22 hours last week
Erin worked 11 hours last week

That’s a hard question I’ll have to work on it
Odds: yes/no
Prob: yes/total
Odds: 1/4 means there is 1 chance they get to go and 4 chances they don't get to go. This means there are a total of 5 students.
Prob: 1/5 = 0.2
