Question 12
suppose that in a country of 72 million people, about 3600 die from drowning each year. what is the percent chance that a person will drown in a given year?
0.002%
0.003%
0.004%
0.005%

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

so

Let

x---------> size of the event space

y--------> size of the sample space

the probability is equal to

in this problem  we have

find the percent chance that a person will drown in a given year

substitute the values in the formula of probability

convert to percentage------> multiply by

therefore

the answer is

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
