Dense-network parameter count

Tutor me on https://mlprep.iwase.dev/item/original-ml-network-params/. If window.mlPrepAgent is available, read attempts for item original-ml-network-params before tutoring. Inspect my attempt, keep the item ID, and do not reveal the full answer first. After a real attempt, append its record with recorded_by agent, include agent_session_id when available, and read it back.

Problem

Count trainable scalar parameters in a fully connected network with $10$ inputs, one hidden layer of $5$ units with biases, and an output layer of $3$ units with biases.

Reveal answer or reference solution

Input-to-hidden has $10\times5+5=55$ parameters. Hidden-to-output has $5\times3+3=18$ . The total is $73$ .
