Answer:
[(1.9+2.4)x5.7/2]-[(2.4x5.7)/2]
Step-by-step explanation:
You take the area of the large triangle (which has a base of (1.9+2.4) and height of 5.7) and subtract the area of the small right triangle (whose base is 2.4 and height is 5.7)
Alternatively, you could use Heron's formula, but I doubt that's what they're looking for.
Answer:
The triangle with base 8 cm and height 10 cm.

1/10 of 32 million is 3.2 million.
Because
1/10 x 32,000,000 = 3,200,000
Answer:
y = 0.714 x -5
Step-by-step explanation:
at x =0, y = -5, means the constant is -5
at x= -7 y= -8,
-8= -7a -5
a=0.714
y = 0.714 x -5
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
