The answer is B because you’d have to cancel out the 4 then add it to 18, since the 4 was negative
Answer:
The closest measurement is 15.7
Step-by-step explanation:
The formula for circumference is 
The diameter is double the radius, so to get the radius we divide by 2.
5 divided by 2 is 2.5
Knowing "r" is 2.5 we can plug that into our equation and solve.
2 ·
· 2.5 ≈ 15.71
The closest measurement is 15.7
The “convenience” sample is the most likely to be a biased set because anything that is chosen out of convenience for the experimenter/observer will be of preference tendency.
Answer:
You = bronze
Your brother = silver
Your sister = gold
Step-by-step explanation:
Your marks: 40/60
Your brother's marks: 46/60
Your sister's marks: 49/60
You can simplify the fractions, but you don't have to:
40/60 = 2/3
46/60 = 23/30
49/60 = 49/60
Now, divide each of the numerators by the denominators (turn the fraction into a decimal).
2/3 = 0.6667
23/30 = 0.7666667
49/60 = 0.8166667
(Note that these are all approximations as the real answers go on forever)
Lastly, multiply them all by 100 to get the percent.
0.6667 x 100 = 66.67% - bronze
0.76667 x 100 = 76.667% - silver
0.816667 x 100 = 81.6667% - gold
