Answer:
C. 0.6766
Step-by-step explanation:
The area of the shaded region between the two z-scores
;
Z=-1.3 Z=0.75
In probability notation we have;
Pr(-1.3<Z<0.75)
From the standard normal tables, we have the following cumulative probabilities;
Pr(Z<0.75) = 0.7734
Pr(Z<-1.3) = 0.0968
Pr(-1.3<Z<0.75) = Pr(Z<0.75) - Pr(Z<-1.3)
Pr(-1.3<Z<0.75) = 0.7734 - 0.0968
Pr(-1.3<Z<0.75) = 0.6766

Answer:
x = 14
Angle B = 121°
Angle C is 59°
Step-by-step explanation:
First we'll find x, then we'll find Angle B (by substituting in x), then we'll find Angle C (bc Angle B and C are supplementary--that us, they add up to 180°)
10x-19 = 7x+23 subtract 7x
3x-19 = 23 add 19
3x = 42 divide by 3
x = 14
Angle B is 10x-19, and if x=14, then its 10(14)-19
Angle B is 140-19
which is 121°
Angle B = 121°
Angle B and Angle C add up to 180°
121° + c = 180°
c = 180-121
Angle C is 59°
