Answer: The mean is the same as the average. In order to find the mean, or average score of the two tests, you need to take the sum of the two tests, and then divide by the number of tests, which is two.
We don't know the score of the second exam. Let it = x
Then we have the following equation:
(88 + x)/2 = 93
88 + x = 2 * 93
88 + x = 186
x = 186 - 88 = 98
You need to score a 98 on the second test
Hi there!
The formula for finding the volume of a sphere is
V = 4/3 × pi × r³
Your problem gives you the radius, so you can just plug in the number into the formula.
r = 14
V = 4/3 × pi × 14³
4/3 × pi × 2744
3658.67 × pi
3658.67 × 3.14 = 11488.2238
You can round up the number to
11488.22
So the volume of the sphere is 11488.22mm³

Step-by-step explanation:
Answer:Diagram is attached.
Step-by-step explanation:
When a point is rotated about the x axis the new point is at an equal distance from the point of rotation.
The given Urn (red) is rotated along the line x=1 .The rotated points will be at equal distance from the line x=1.In the figure the blue Urn is the rotated figure about the line x=1.
The coordinates of the points are mentioned in the diagram attached .In the rotated figire the y values remains same while for x coordinateis of the point at the same disstane from line x=1 .
Answer:
The function is increasing for all real values of x where x < -1 and where x > 4
Step-by-step explanation:
The function is "not" increasing for all real values of x where x<0, when
-1 < x < 0
