blsea [12.9K]

Answer:

= -120a³b²c²

Step-by-step explanation:

10ac * 6ab * -2abc

10*6*-2 = -120

ac * ab * abc = a*a*a *b*b*c*c = a³b²c²

then:

10ac * 6ab * -2abc = -120* a³b²c²

= -120a³b²c²

In 2012, entering freshmen at the UA have an average ACT score of 25.4 with a standard deviation of 2.1. 1. What is the probabil

astra-53 [7]

Answer:

P [ Z > 24,1 ] = 72,24 %

Step-by-step explanation:

P [ Z > 24,1 ] = 1 - P [ Z < 24,1 ]

P [ Z < 24,1 ] = ( Z - μ₀ ) / σ

P [ Z < 24,1 ] = ( 24,1 - 25,4) / 2,1

P [ Z < 24,1 ] = - 1,3/ 2,1

P [ Z < 24,1 ] = - 0,6190 ≈ - 0,62

We look in z-table and find for z(score) -0,6190

P [ Z < 24,1 ] = 0,27763

Then

P [ Z > 24,1 ] = 1 - 0,27763

P [ Z > 24,1 ] = 0,72237 ⇒ or P [ Z > 24,1 ] = 72,24 %
