You can do
83 - 5 to find the answer
So that's
78 or
5 + 78 = 83
Answer:
<em>y=7x+1</em>
Step-by-step explanation:
<u>Linear modeling</u>
Consists of finding a linear equation that represents a situation in real life.
Jenny starts her stamps collection with only 1 stamp.
Then she collects 7 stamps per day.
Let's call
y=total amount of stamps in Jenny's collection
x=number of days
Knowing Jenny collects 7 stamps per day, then in x days, she collects 7x stamps. The total amount can be obtained by adding the first stamp she had. Thus, the model is:
y=7x+1
First you gotta change it to a fraction, which would be 6/10 because it's in the tenths place. Now simplify it, which would be 3/5.
0.15 is bigger, cause the second digit after the decimal is bigger. You would have to add another 0.025 to 0.125 to bring it up to 0.15
The correct answer is C. The interquartile range shows us how the middle 50% (from the 25th to the 75% percentile) of the data is spread out.
