The range of a data set is 18 is the smallest number in the set is 9 what is the largest number

The Largest Number is 27.

Step-by-step explanation:

Range = Largest Number - Smallest Number

18 = Largest Number - 9

Rearrange the formula to find the Largest Number:

Largest Number = Range + Smallest Number

Largest Number = 18 + 9

Largest Number = 27

You can check this by putting it into the original formula:

Range = Largest Number - Smallest Number

18 = 27 - 9

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
