Answer: 38 over 49 can be written as 38/49. When divided, you will get 0.77551020408. It takes lots of regrouping, but it ends eventually.
If you are reducing it as a fraction, it is not possible because there is no other number to reduce it, so it will be in it's simplest form already.
Answer:
I think A is the answer
Step-by-step explanation:
Comment down if I am wrong but if I am right give me stars or a thank you or a thank you comment.
The empirical rule states that in a normal distribution,
68% of data is within 1 std deviation of the mean
95% of data is within 2 std deviation of the mean
99.7% of data is within 3 std deviation of the mean
In this case 95% of the cases would be within two std deviations of the mean
mean - 8 and mean + 8
72 - 8 = 64 and 72 + 8 = 80
then 95% of the scores are between 64% and 80% on the test.
The
mean absolute deviation will show us on average how far each of all
the data points from the graph that Makayla collected are from the
mean. To calculate it you simply have to use the formula shown in the
attachment. It is very easy but will take you like 5 minutes to
solve. Use it for each data set.
