1. if the range for a set of data is 24, from 2 to 26, and the mean is 17, what can you conclude about the data?

a. 17 is the typical data value.
b. not enough information to draw valid conclusion.
c. the median will be 17 also.
d. there probably isn't a mode.

2. what is the range for the following set of data?

5, 7, 8, 10, 12, 12

a. 5
b. 7
c. 9
d. 12

3. what is the mean for the following set of data, to the nearest whole number?

5, 9, 15, 18, 22

a. 13
b. 14
c. 15
d. 17

1. is B. not enough info(??)

2. is B. 7

3. is B. 14

The last two are correct for sure.

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
