Question

Suppose Blue Spruce was included in the list and the mean decreased to feet. What is the height of the Blue Spruce?

Answer 1

the answer is 45 i think

Answer 2

The height of the blue spruce was 45.

Explanation:

(160+320+100+110+200+220+x)/7 = 165

(1110+x)/7 = 165

Multiply both sides by 7:

1110 + x = 1155

Subtract 1110 from both sides:

x = 45

Hope this helps
