ANSWER
1 bell shape
2 to find probability when sampling
EXPLANATION
1 In a normal distribution, the mode,mean and median are equal.
As a result, the distribution is neither skewed to the right or left.
The shape of the normal distribution looks like a bell.
That is why it is also called the bell curve.
2. The area under the normal curve is 1.
The line of symmetry of the bell shaped distribution divides it into two halves with area 0.5 each.
The normal curve is therefore used to find the probabilities of a sample distributions.
Answer:
Im not sure that really makes sense but I think your grade would be 90% if you did 8/9 or somewhere around that
Step-by-step explanation:
60 minutes=1 hour
360 minutes=6 hours
so 360 minutes/90 minutes
so your answer is 4 hours
It will travel 180 miles
4.5 • 40= 180
