Answer:
0.395 or 39.5% probability that the first metal-carrying person missed (not detected) is a
Step-by-step explanation:
The easiest way to solve this problem is to determine the probability of all 50 of the first 50 metal-carrying people scanned being caught by the metal detector (P(C)). Then, the probability that the first metal-carrying person missed is within the first 50 (P(M)) is 100% minus the probability of all 50 being caught:
There is a 0.395 or 39.5% probability that the first metal-carrying person missed (not detected) is among the first 50 metal-carrying people scanned.
Answer: Hundreds: 5,700
Ones: 5,693
Step-by-step explanation:
212.5 miles
If the car is moving at 50 miles per hour, that means in 1 hour, it traveled 50 miles. In 2:100, 3:150, & 4:200. 1/4 of 50 is 12.5. So, when travelling for 4 1/4 hours, the vehicle traveled for 212.5 miles.
Answer: d. 0.55
Step-by-step explanation:
The given probability distribution:
Number of Goals 0 1 2 3 4
Probability .05 .15 .35 .30 .15
The probability that in a given game the Lions will score less than 3 goals
= probability that in a given game the Lions will score less than or equal to 2
= 0.5+0.15+0.35
= 0.55
Hence, the correct option is d. 0.55
Answer:
13.04 cm^2
Step-by-step explanation:
Larger Circle diameter is 12.5 cm and the smaller is 3.5 cm
The Area of a circle is A = πr^2 = πd^2/4
Larger Circle divide the diameter by 2 = 6.25 cm
Smaller Circle dive the diameter by 2 = 1.75 cm
Using above formula A = 122.71846303085 cm^2 &
Finally we deduct the smaller Area from the larger Area
A = 9.6211275016187 cm^2 - 9.6211275016187 cm^2
122.71846303085 cm^2 - 9.6211275016187 cm^2 =
113.0973355292 cm^2 thus 13.04 is your answer since I used the
π = 3.1415926535898
A = area
π = pi = 3.1415926535898
