Answer: 0.81859
Step-by-step explanation:
Using the formula ;
Z = 
where u = mean
Therefore the probability that a student will finish the test between 40 and 70 will be :
P ( 40≤X≤70 ) = P(X≤70) - P(X≤40)
P ( 60-40/10) , P( 60 - 70 / 10)
= 2 , -1
= P (Z ≤ 2) - P( Z ≤ -1 )
From normal table , we have
0.97725 - 0.15866
Therefore the probability that a student will finish the test between 40 and 70 minutes = 0.81859
The coordinates of the fourth corner is
A. (-1, 3)
No, all regular polygons does not have even number of sides.
Suppose, heptagon which is a regular polygon which has 7 sides.
But, all the sides of any regular polygon are equal in length.
Here is the answer. A minute consists of 60 seconds. Therefore, we can put this in a fraction form as 42/60. Since these are still large numbers, we would simplify this fraction so the answer would be 7/10. Hope this is the answer that you are looking for. Have a great day ahead!
