<h3>
Answer: 0.14</h3>
=======================================================
Explanation:
There are
- 5 students who got an A
- 35 students total
We divide these two values to get the probability we want
5/35 = 1/7 = 0.142857 which is approximate
This rounds to 0.14 when rounding to the nearest hundredth.
There's about a 14% chance of randomly selecting someone who got an A.
Answer:
Volume = 
Step-by-step explanation:
Given - Consider the solid S described below. The base of S is the triangular region with vertices (0, 0), (4, 0), and (0, 4). Cross-sections perpendicular to the x-axis are squares.
To find - Find the volume V of this solid.
Solution -
Given that,
The equation of the line with both x-intercept and y-intercept as 4 is -

⇒x + y = 4
⇒y = 4 - x
Now,
Volume = 
where
A(x) is the area of general cross-section.
It is given that,
Cross-sections perpendicular to the x-axis are squares.
So,
A(x) = (4 - x)²
As solid lies between x = 0 and x = 4
So,
The Volume becomes
Volume =
