Answer:
He needs to score a 19
Step-by-step explanation:
First, I found the mean of the three test scores. The mean was below 17 so I knew he needed a grade higher than the ones he already has. So I went up from 18. So my first equation was 15+18+16+19=68. then I divided by 4 which gives you a mean of 17. (Mean=average)
It’s x=0 isn’t it that answer
Answer:
I would say that the last one is False and A and C are true.
Hope this works.
Answer:
1/4
Step-by-step explanation:
One can determine whether a binary tree is a binary search tree by traversing it in is In-order Traversal.
<h3>How do you traverse a binary search tree?</h3><h3>In-order Traversal</h3>
In this traversal method, the left subtree is visited first, then the root and later the right sub-tree. We should always remember that every node may represent a subtree itself. If a binary tree is traversed in-order, the output will produce sorted key values in an ascending order.
As,
In the case of binary search trees (BST), In-order traversal gives nodes in non-decreasing order.
For Inorder, you traverse from the left subtree to the root then to the right subtree.
To get nodes in non-increasing order, Inorder traversal s reversed can be used.
Hence, traversing is Inorder
