Answer:
8 = x
Step-by-step explanation:
16 = 8+x
Subtract 8 from each side
16-8 = 8-8+x
8 = x
Remark
You could solve it using logs. Either base will do. They both will give you the same answer (I'll put the second solution before the first one).
Step one
Take the log of both sides.
Log 37^x = log 12
Step Two
Using the power rule for logs, multiply x by the log(37)
x*log(37) = log (12)
Step three
Divide both sides by the log(37)
x = log(12) / log (37)
x = 1.079 / 1.568
x = 0.6882 <<<<< Answer
Use ln
ln 37^x = ln12 Take ln of both sides.
x*ln(37) = ln(12) Multiply x (the power by ln(37)
x = ln(12) / ln(37) Divide by ln(37)
x = 2.485 / 3.611
x = 0.6882
You should be able to put the sentences together just the way I've done it.
<span>To find this z-score, locate the score on the table such that the area of the curve to the right is 0.37. This is similar to the 37th percentile. After locating it, you will see that the z-score is 0.3319.</span>
