Change 4 1/3 to improper fraction: 13/3
13/3 * 18/1 = 234/3
234/3 = 78.

Answer:
A. P(success/age≥60) = 12.5%
B. Yes, the success is independent of age.
Step-by-step explanation:
Probability of success, given that a climber is at least 60 years old is calculated using conditional probability rule
P(A|B) = P(A n B)/P(B)
Probability of success given that a climber is at least 60 years old is given by
P(success|age≥60) = P(success n age ≥ 60)/P(age ≥ 60) = 0.005/0.04
= 0.125
P(success|age≥60) = 12.5%
B. The success is independent on age
Answer:
d. parabola, 0°
Step-by-step explanation:
y² + 8x - 0
y² = -8x
Where x = cos t , y = sin t
Sin² t = -8 Cos t
1 - Cos² t = -8 Cos t
- Cos² t + 8 Cos t + 1 = 0
t = 2лπ ± (3 + √10) , л∈Z
Angle of rotation

correct question
Charles drew a regular hexagon and divided it into two identical trapezoid , the side length of the hexagon iscoming16cm,the diagonal shown in fig 30 is 32 cm Charles measure the height of one the trapezoid and found that the height was 13.9 cm find the area of the area
Step-by-step explanation:
The side length of the hexagon should be given which is 16 cm
To get the Length the side length makes with the height of the trapezium, Pythagoras theorem is applied to get the base of the triangle
Base = √((16)^2 - (13.9)^2
Base = √62.29
Base = 7.92cm
Since we have gotten the base
Diagonal - the base gives the top length of the trapezium.
32- 7.92- 7.92 = 16.16
The area of the hexagon gives the 2 times of the trapezium.
To find the area of the trapezium
= 1/2 * ( a+b)h
= 1/2* ( 32+ 16.16)* 13.9
= 24.04*13.9
Area of the trapezium = 334.71cm2
= 334.71 * 2
= 669.42cm2
