Final answer:
The missing term in the proportion 11:n = 33:15 is found using the cross product rule, resulting in n = 5.
Step-by-step explanation:
To find the missing term in the proportion using the cross product rule, we need to set up an equation where we multiply the means and extremes and then solve for the unknown. The original proportion is 11:n = 33:15. Applying the cross product rule, we get:
11 × 15 = n × 33
Solving for n:
165 = 33n
Dividing both sides by 33:
n = 165/33
n = 5
So, the missing term in the proportion is 5.
