Answer:
28.26
Step-by-step explanation:
Circumference= 2 pi x r
Diameter= 9 (double the radius)
Radius= 4.5
Pi= 3.14
2 x 3.14= 6.28
6.28 x 3.14= 28.26

Answer:
The required probability is 0.9916
Step-by-step explanation:
Consider the provided information.
If 45% of cars are traveling in excess of 70mph,
Therefore, p = 0.45
q = 1-p = 1-0.45 = 0.55
8 random cars are measured via radar: n = 8
We need to find at least 1 car is going over 70mph.
According to binomial distribution:
We need to find P(X≥1)
Hence, the required probability is 0.9916
Answer: 5 inch by 6 inch
Explanation:
What will the dimensions of the poster be if she scales it down by a factor of one - third
Let us scale down each side one by one.
The poster is 15 in by 18 inches in dimensions
The new dimensions will be
15 × 1/3 = 5 inch
18 × 1/3 = 6 inch
The correct answer is 5 inches by 6 inches.
