class size m average 0.82 n class n average 0.78. if the average for combined classes is 80%, what is relationship between m and
katen-ka-za [31]

Answer:

The relation between m and n is ,  m = n      

Step-by-step explanation:

Given as :

The average for n class  = 0.82 = 82%

The average for m class  = 0.78 = 78%

The average for ( m + n ) class  = 80%

So , \frac{x_1 +x_2+x_3+x_4+ ....... + x_n}{n} = 82%

And \frac{x_1 +x_2+x_3+x_4+ ....... + x_m}{m} = 78%

And , \frac{(x_1+x_2+x_3+x_4+ ......+x_n ) + (x_1+x_2+x_+x_4+.....+x_m)}{m+n} = 80%

So , 0.82×n + 0.78×m = 0.80× (m+n)

Or,  0.82×n - 0.80×n = 0.80×m -   0.78×m

Or,   0.02×n              =  0.02×m

Or,   \frac{m}{n} =  \frac{0.02}{0.02}

∴      \frac{m}{n} = 1

I.e     m  =  n

Hence The relation between m and n is ,  m = n      Answer

Is this correct? Pls help within 10 minutes will mark brainliest
Vedmedyk [2.9K]

Answer:

the first answer is correct

the second answer is correct if they messed up on the question and meant to ask for the MAD of set B

I think the 3rd answer is incorrect (I got 1.09), so you might want to double-check your 3rd answer since it is asking for "times bigger", not how much bigger, which means how many times larger is the MAD of set A than that of set B and to find how many times bigger a number is than another number, you have to divide the first number by the second number.
