Answer:
The fraction of the area of ACIG represented by the shaped region is 7/18
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
In the square ABED find the length side of the square
we know that
AB=BE=ED=AD
The area of s square is

where b is the length side of the square
we have

substitute


therefore

step 2
Find the area of ACIG
The area of rectangle ACIG is equal to

substitute the given values

step 3
Find the area of shaded rectangle DEHG
The area of rectangle DEHG is equal to

we have


substitute

step 4
Find the area of shaded rectangle BCFE
The area of rectangle BCFE is equal to

we have


substitute

step 5
sum the shaded areas

step 6
Divide the area of of the shaded region by the area of ACIG

Simplify
Divide by 5 both numerator and denominator

therefore
The fraction of the area of ACIG represented by the shaped region is 7/18
Answer:
1). m° = 56.1°
2). X= 91.8 mm
Step-by-step explanation:
For angle m°
Using the sine rule
15.1/sin m= 18.2/sin 90
But Sin 90= 1
15.1/sin m= 18.2
15.1= 18.2*sin m
Sin m = 15.1/18.2
Sin m=0.8297
m= sin^-1(0.8297)
m= 56.06°
m° = 56.1°
For length of side x
Using sine rule
X/sin 61= 105/sin 90
But sin 90= 1
X/sin 61= 105
X = sin61 *105
X=0.8746*105
X= 91.833 mm
X= 91.8 mm
Using conditional probability, it is found that there is a 0.2273 = 22.73% probability that a student took AP Chemistry, given they did not get into their first-choice college.
Conditional Probability
In which
- P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem:
- Event A: Did not get into their first-choice college.
- Event B: Took AP chemistry.
According to the chain given, the percentages associated with not getting into their first-choice college are:
Hence:

The probability of both not getting into their first-choice college and taking chemistry is 0.1375, hence 
Then, the conditional probability is:

0.2273 = 22.73% probability that a student took AP Chemistry, given they did not get into their first-choice college.
