Answer:
Part 6)
case a)
case b)
Part 7)
case a)
case b)
Step-by-step explanation:
we know that
The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the sample space is the total number of possible outcomes
The event space is the number of outcomes in the event you are interested in.
so
Let
x------> size of the event space
y-----> size of the sample space
so
Part 6)
case a) P(odd)
In this problem we have
substitute
case b) P (less than 3)
In this problem we have
substitute
Part 7)
case a) P(yellow)
In this problem we have
substitute
case b) P(green and red)
therefore
X=-.25,-.5,-1,1,.5,.25
y=1,2,4,-4,-2,-1
Let us first convert 10 minutes 12 seconds in seconds.
So
10 minutes 12 seconds = (10 * 60 ) + 12 seconds
= 600 + 12 seconds
= 612 seconds
Now
Let us convert the 612 seconds into minutes
612 seconds = 612/60 minutes
= 10.20 minutes
Now
The distance covered by Marnie in 10.2 minutes = 1 mile
hen
Distance covered by Marnie in 60 minutes = (60/10.2) miles
= 5.88 miles
Then the unit rate will be 5.88 miles per hour
Sometimes
1. The radical expression
with even n requires <span>a variable with positive quantity. For example, if you have
, then always
.
</span>
2. If you have radical expression
with odd n, ia variable may be arbitrary. For example, for
you can consider all real x.
