Answer:
The last method (Round 13.76 to 14, round 9.8 to 10, and round 16.415 to 16; since 14 + 10 + 16 = 40 and 40 is close to 39.975, her answer is reasonable.)
Step-by-step explanation:
Option 1 is unreasonable because removing the decimal points just changes the whole problem and claims that Harshini rode her bike 1376 kilometers on Monday and etc., which she did not. Option 2 is unreasonable because not all the numbers are near 20 and should be rounded to their nearest whole numbers instead to find a more accurate estimate. Option 3 is unreasonable for the same reason as option 2, the numbers should be rounded to their nearest whole numbers instead to find a more accurate estimate. Option 4 is reasonable because the numbers are rounded to the nearest whole numbers which makes the estimate more accurate.
#a
V={Vowels of English alphabets}
#b
C={cube numbers between 0 to 50}
#c
M={y:y is a multiple of 3 less than 20}
The y intercept in this graph is (0,1) ad the only equations that fit this are a and c.
To figure out whether it is a or c, find the slope. The line of the equation is going up, so he slope is positive. Equation c has the positive slope.
EQUATION C
The square root of 12 is 3.4.
Your integers are 3 and 4.
I hope this helps!
