Evaluate this expeession 11/16 plus 4/10 -3/4

27/80

Step-by-step explanation:

First, we need all the fractions to have a common denominator.

The closest possibility is 80, so we multiply

Multiply:

11/16 times 5= 55/80

4/10 times 8= 32/80

-3/4 times 20= -60/80

Addition:

55/80+32/80=87/80

Subtraction:

87/80-60/60= 27/80

Since it cannot be simplified any further this is our answer

I hope this helps u pls give a brainliest and a thanks ;)

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

two data sets with the same median will not have the same varaibility
