Which statement is true of the data? The center of distribution for 8th grade is greater than the center of the distribution for 7th grade.

The spread of the distribution for 8th grade is equivalent to the spread of the distribution for 7th grade.

The interquartile range of the distribution for 7th grade is 1.5 times the interquartile range of the 8th grade.

The lower quartiles for both data distributions are equal.

A.

Step-by-step explanation:

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
