Answer:
12.7
Step-by-step explanation:
Answer: The correct answer is B) 21%
Step-by-step explanation:
This is a binomial model probability problem. We need to find the probability of 6 out of 10 new births at a hospital being boys. The information we need is the number of trials observed, the number of successes and the percentage chance you have of any birth being a boy. The number of trials are 10, with the number of successes being 6 (the number of trials we want to be boys) It states that 51% or 0.51 of all births in the US are boys so we can use this value to determine our answer using our binomial model formula. After simplifying we get our answer of 21% I hope this has been of use to you :)
Have a wonderful rest of your day!

600
Step-by-step explanation:
Volume=l*b*h=5*12*10=600
Answer:
450 km (rider a)
360 km (rider b)
Step by-step explanation:
(if they are going at a constant speed you can choose any point)
find how fast rider a is going:
60/2 = 30 km/h
find how fast rider b is going:
72/3 = 24 km/h
30 km/h for 15 hours = 30 x 15 = 450 km (rider a)
24 km/h for 15 hours = 24 x 15 = 360 km (rider b)
Answer:
176.7 square feet
Step-by-step explanation:
Diameter, d = 15 feet
radius, r = d/2
r = 15/2 = 7.5 feet
π = 3.142
Area of the pool = area of a circle
= πr^2
= 3.142 * 7.5^2
= 176.7375
to the nearest tenth
= 176.7 square feet
