Answer:
Initial height or what the ball was originally bounced from a height of 9 feet
Step-by-step explanation:
9 represents the height that the ball was originally bounced from.
If you plug in 0 for into , you get:
.
9 feet is the initial height since that is what happens at time zero.
Answer:
Step-by-step explanation:
(3,-3)
This is true.
When we're talking about the mode, we're usually talking about the number which has the highest frequency in a given set of numbers. For example, out of the numbers:
1 2 3 4 5 6 5 4 5 5 5
5 will be the mode.
Answer:
0.6568 = 65.68% probability that she would be correct.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
45000, 45500, 44500, 46000 and 44000 units. This rate of sales is considered average for the product over the last twenty years or so.
This means that:
Standard deviation of 1500 units.
This means that
What is the likelihood that she would be correct if she predicts sales between 43000 and 46000?
This is the pvalue of Z when X = 46000 subtracted by the pvalue of Z when X = 43000. So
X = 46000
has a pvalue of 0.7486
X = 43000
has a pvalue of 0.0918
0.7486 - 0.0918 = 0.6568
0.6568 = 65.68% probability that she would be correct.
Fewer numbers of larger units are required to describe the same volume.
a) If the unit of measure changes from a smaller unit to a larger one, the number of units gets smaller
b) The volume doesn't change.
_____
This should be intuitively obvious to anyone with the experience of puting things into containers of any kind. Fewer large containers are required to hold the same amount of stuff that occupies many smaller containers.
_____
<u>Example</u>
54 ft³ = 2 yd³ . . . . the number of units used to describe the volume changes from 54 to 2. The volume is still 93,312 cubic inches. (Note also that both 54 and 2 are smaller than 93,312.)
