Answer:
Average of the draws equals 420
Standard Error = 11.88
Step-by-step explanation:
Given
Solving (a): The average of the draws
This implies that we calculate the sample mean
This is calculated as:
--- Sample Mean = Population Mean
So, we have:
Solving (b): The standard error
This is calculated as:
So, we have:
Using the calculator, we have:
Answer:
The center circle of this question is (2,3)
Answer:
192 cards
Step-by-step explanation:
multiply the 16 cards by 12, 12x5=60=1 hour
B is the correct answer.....
Heya !
Using a theoram about triangles ,
Given a triangle ∆ABC, the sum of the lengths of any two sides of the triangle is greater than the length of the third side ,
Also , the length of third side always greater than absolute difference of the other two sides ,
Let the third side be x ,
So , x < 9 + 8 and x > 9 - 8
x < 17 and x > 1
Hence , x ∈ [ 2 , 17 ] inch.
Above case is true for any triangle , be it scalene , Isosceles , Right-angled ...
As , for Isosceles , the third side can be 8 or 9 inches ,
For scalene , all values in the above range satusfies ,
For right angled triangle , we have 2 cases ,
Case 1 : Third side is the hypotenuse
Then , x = √(9²+8²) = √145 = 12.0415 inch.
Case 2 : Third side is not the hypotenuse
Then , x = √(9²-8²) = √17 = 4.1231 inch.
Hope it helps you ! :)
