Atrip to a nearby island takes 2 1/3 hours by boat and 1/3 hour by plane. how many times fast as the boat is the plane?

Well I will do it this way..A boat can travel 225 miles in the same time that a plane can fly 375 miles. The boat travels 60 miles per hour slower than the plane. So it is obvious that the boat is slower in general.

Step-by-step explanation:

But since this is math wise and not statistic wise I will say 13 times as fast.

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
