Judy thinks there will be 325 people at the county fair on Friday, while Atticus thinks that there will be 600 people. On Friday

lana66690 [7]

Answer:

-Judy is closest to real value.

-% difference is 4.6%

Step-by-step explanation:

-We calculate the margin of errors for both Judy and Atticus:

$ME_j=|Real value -Assumed|\\\\=|452-325|\\\\=127\\\\\\ME_a=|Real \ Value- \ Assumed|\\\\=|600-452|\\\\=148\\\\ME_a>ME_j$

We realize that Judy's assumed value was nearer to the eal value than Atticus'.

The percentage ME difference is calculated as:

$\% ME=\frac{ME}{Real \ Value}\\\\=\frac{148-127}{452}\\\\=0.04646=4.6\%$

Hence, the % error difference is 4.6%

Please show me the steps of to do this <br> DON"T GIVE ME THE ANSWER<br> ASAP

kherson [118]

Answer:

Step-by-step explanation:

The number $a . 10^{-2}$ is 8 times greater than $b . 10^{-3}$

thus, $a . 10^{-2} = 8b. 10^{-3}$

multiply both sides by $10^{2}$

we get $a = 8b. 10^{-1} \\a = 0.8 b$

if we take a = 2.5 and b = 3.1 we get 2.5/3.1 = 0.8

then B is the answer
