Answer:
The estimated amount of metal in the can is 87.96 cubic cm
Step-by-step explanation:
We can find the differential of volume from the volume of a cylinder equation given by

Thus that way we will find the amount of metal that makes up the can.
Finding the differential.
A small change in volume is given by:

So finding the partial derivatives we get


Evaluating the differential at the given information.
The height of the can is h = 26 cm, the diameter is 10 cm, which means the radius is half of it, that is r = 5 cm.
On the other hand the thickness of the side is 0.05 cm that represents dr = 0.05 cm, and the thickness on both top and bottom is 0.3 cm, thus dh = 0.3 cm +0.3 cm which give us 0.6 cm.
Replacing all those values on the differential we get

That give us

Or in decimal value

Thus the volume of metal in the can is 87.96 cubic cm.
Given:
Total number of students = 27
Students who play basketball = 7
Student who play baseball = 18
Students who play neither sports = 7
To find:
The probability the student chosen at randomly from the class plays both basketball and base ball.
Solution:
Let the following events,
A : Student plays basketball
B : Student plays baseball
U : Union set or all students.
Then according to given information,




We know that,



Now,





It means, the number of students who play both sports is 5.
The probability the student chosen at randomly from the class plays both basketball and base ball is


Therefore, the required probability is
.
Answer: slope = 3
Step-by-step explanation:
We can see from the point intersecting the y axis (y-intercept) to the point (1, 1) it goes up 3 and right 1 giving us the slope
simplified to 3
2/10 of a gallon. 1/10 is half so then 1/10 times 2 would equal 2/10
