Kevin bowled 7 games last weekend. His scores are: 115, 165, 138, 172, 127, 193, 142. What is Kevin's median score?

172.

Step-by-step explanation:

115, 165, 138, 172, 127, 193, 142

The median is the middle number, which is 172.

Uneven amount? Here’s a trick, 7 + 1 = 8 / 2 = 4, so the fourth number is the median.

the least common denominator is 40

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
