Answer:
Probability that Ryan is both certified and has never had an accident is undefined
Step-by-step explanation:
Given;
Probability that Garrick is certified = P(G) = {25}
Probability that Molly has not had an accident = P(M) = {71.87}
Probability that Ryan is both certified and has never had an accident = P(R) = {?}
Probability of Ryan being certified was not defined,
Probability that Ryan has not had an accident was not also defined
Therefore, Probability that Ryan is both certified and has never had an accident = P(R) = is undefined, since Ryan is not within the given set.
so if you read 450 out of 720 that could be represented as a fraction as 450/720 but normally you would simplify it by finding the greatest common factor or the GCF and for this problem the GCF would be 90 so we would divide both sides by 90, so 450/90 is 5 and 720/90 is 8 so that leaves us with 5 as our numerator and 8 as the denominator or 5/8 also shown as 0.625(decimal version). That is all. I hope that this wasn't too confusing and if there are any wrong parts please do correct me . Thank you

Step-by-step explanation:
Answer:
1. Area of the garden = 84 inch²
2. Diameter = 12 ft
Step-by-step explanation:
1 The area of the garden can be computed when you separate the composite shape into simpler ones. The shape can be separated into a trapezium and a rectangle.
The area of the garden will be the area of the rectangle plus the area of the trapezium.
area of rectangle = length × width
length = 10 inches
width = 5 inches
area of the rectangle = 10 × 5 = 50 inches²
Area of the trapezium = 1/2(a + b)h
a = 7 inch
b = 15 - 5 = 10 inch
h = 4 inch
area of the trapezium = 1/2 (7 + 10)4
area = 1/2(17)4
area = 68/2
area of the trapezium= 34 inch²
Area of the garden = 34 inch² + 50 inch² = 84 inch²
2. volume of a cylinder = πr²h
volume = 252π ft³
h = 7 ft
252π = π × r² × 7
252π = 7πr²
divide both sides by 7π
r² = 252π/7π
r² = 36
square root both sides
r = √36
r = 6 ft
Diameter = 2 × radius
Diameter = 2 × 6
Diameter = 12 ft
