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
To find the area we need to do the things below:
Let:
42 = perimeter of KLMN
h1 = 5
h2 = 6
the perimeter of a parellelogram is equal to 2 (a +b)
let:
a = KL
b = LM
area of a parallelogram = bh
(also known as base x height)
b = LM
h = h1
Find the values of a and b in order to solve for the area of KLMN. Similar triangle means they are proportionality is equal.
P = 2 (a +b)
42 = 2(a+b)
12/2 = a + b
21 = a+b
21 -a = b
note:
hypotenuse / long leg
a / 5 = b/6
(21-a) / 6
a*6 = 5 (21 - a)
6a = 105 - 5a
6a + 5a = 105
11a = 105/11
= 9.55
b = 21 -a -> b = 21 - 9.55
b = 11.45
using the equation of the area of parallelogram:
area = bh
A = 11.45 * 5
A =57.25 square units
*below is an attached figure of the problem
1 horse → 5o mL
3 horses → 50 x 3 = 150 mL
1 sheep → 4L
15 sheep → 4 x 15 = 60 L - 60 000mL
1 chicken → 200 mL
12 chicken → 200 x 12 = 2400 mL
Total = 150 + 60 000 + 2400 = 62550mL or 62L and 550mL
Answer: 62L and 550mL
