<span>A. When adding two rational numbers a/b and c/d, the numerators a and c do not have to be integers. Therefore, the sum does not have to be a rational number. I think this is right might nor be :/

There were 16 total storms, meaning our denominator is 16. Since 8 grew into hurricanes, we can leave that alone. Since 5 out of 16 storms were major, 5 is our numerator.
5/16 storms were major because 8 were hurricanes and the other 3 were other kinds of storms. As a decimal conversion, about 31% of these storms were major.
How to find the percentage conversion:
Step 1: We take the fraction 5/16.
Step 2: Since our numerator is 5 and the default denominator is a maximum of 100, we can multiply 5 by 100.
5 x 100 = 500
Step 3: We can divide 100 by 16 to get our decimal conversion.
100 divided by 16 will give us 31.25, which also is representative of 31 and 1/4 added together.
Your final answer: With there being 16 storms, 5 of these storms are major (5/16). In terms of if there were 100 total storms, about 3/10 of these storms were major.
Answer:
180 and 2.5
Step-by-step explanation:
for the second collum over 3 it would be 180
For the one under 150 it would be 2.5
let me know if you need a better explanation
Answer:
4.25
Step-by-step explanation:
Here in this question, we want to calculate the mean absolute deviation of the data.
The first thing we will do here is to calculate the mean;
= (74 + 79 + 76 + 85 + 87 + 83 + 86 + 78)/8 = 81
Now, the next thing to do here is to calculate how far each of the values have deviated from the mean. This can be calculated by subtracting the mean from each individual value;
This is presented in the table on the attachment, please check attachment for this
Afterwards, we find the absolute value of all these subtractions then divide by 8 which is the number of values in the data.
Mean absolute deviation = Sum of all absolute deviations/number of values in dataset
