The absolute change is the difference: 6.88 - 7.25 = -0.37
The rate of change is that divided by the originalprice x 100
Ratre of change: (-0.37/7.25 )*100 = -4.93%
I would say 95/6 because you multiply 5 and 15 and turn it into an improper fractions
Both of these conditions must be true in order for the assumption that the binomial distribution is approximately normal. In other words, if and then we can use a normal distribution to get a good estimate of the binomial distribution. If either np or nq is smaller than 5, then a normal distribution wouldn't be a good model to use.
side note: q = 1-p is the complement of probability p
4. The answer is -7 and 7. Start at 0 and count to the left. That’s -7. Then to the right it’s 7
Label the width: 4ft
Label the length: 12ft (4ft for each segment).
Perimeter=12+12+4+4=32ft
