<h3>What is a Number Line?</h3>This refers to the line that shows numbers from left to right and is marked at intervals that are negative to the left and positive to the right.
Based on the keen observation, there are 10 line segments that have an equal length and from the two points, there are two equal line segments,
So, the probability that a random point would fall between A and B is:
Number of line segments between AB/ number of line segments between AE
= 2 /10
= 1/5

Solution: We are given:
We have to find the amount of water that represents the top 97.5%.
We need to find the z value corresponding to probability to 0.975. Using the standard normal table, we have:
Now using the z score formula, we have:
Therefore, 129.4 ounces amount of water represents the top 97.5%
Answer:
The measure of bottom of ladder from bottom of building is 48 .
Step-by-step explanation:
Given as :
The length of the ladder = l = 50 foot
The height of the building = h = 14 foot
Let The measure of bottom of ladder from bottom of building = x foot
Now from figure
<u>The figure is of right angled triangle</u>
So,
Hypotenuse² = perpendicular² + base²
Or, OB² = AB² + OA²
Or, OA² = OB² - AB²
Or, x² = (50)² - (14)²
Or, x² = 2500 - 196
Or, x² = 2304
∴ x =
I.e x = 48
So,The measure of bottom of ladder from bottom of building = x = OA = 48 foot .
Hence, The measure of bottom of ladder from bottom of building is 48 . Answer
