Answer:
no f-ing clue
Step-by-step explanation:
Answer:
I assume you would know how to make a regular graph???
So, you would plot the points at:
(2, 5)
(3, 8)
(4, 13)
(5, 12)
(6, 18)
(7, 20)
I hope this helps you!
Answer:
Step-by-step explanation:
<u>a)</u>
- Given that ; X ~ N ( µ = 65 , σ = 4 )
From application of normal distribution ;
- Z = ( X - µ ) / σ, Z = ( 64 - 65 ) / 4, Z = -0.25
- Z = ( 66 - 65 ) / 4, Z = 0.25
Hence, P ( -0.25 < Z < 0.25 ) = P ( 64 < X < 66 ) = P ( Z < 0.25 ) - P ( Z < -0.25 ) P ( 64 < X < 66 ) = 0.5987 - 0.4013
- P ( 64 < X < 66 ) = 0.1974
b) X ~ N ( µ = 65 , σ = 4 )
From normal distribution application ;
- Z = ( X - µ ) / ( σ / √(n)), plugging in the values,
- Z = ( 64 - 65 ) / ( 4 / √(12)) = Z = -0.866
- Z = ( 66 - 65 ) / ( 4 / √(12)) = Z = 0.866
P ( -0.87 < Z < 0.87 )
- P ( 64 < X < 66 ) = P ( Z < 0.87 ) - P ( Z < -0.87 )
- P ( 64 < X < 66 ) = 0.8068 - 0.1932
- P ( 64 < X < 66 ) = 0.6135
c) From the values gotten for (a) and (b), it is indicative that the probability in part (b) is much higher because the standard deviation is smaller for the x distribution.
Many fractions including 1/5, 2/10, 3/15, 4/20 and up.
Answer:
see below
Step-by-step explanation:
-2x^4-x^3+8x^2-12
First list by highest power to lowest power
The highest power is x^4 so this is a 4th degree polynomial or a quartic polynomial
If you really mean the multiply sign
-2x^4-x^3*8x^2-12
-2x^4 - 8x^5 -12
-8x^5 -2x^4 -12
This would be a 5th degree or quintic
