The senior class of a high school needs to decide where to go for their senior trip. they have four choices: a cruise, a camping trip, a snorkeling trip, or to the great wall of china.

due to budget constraints they cannot survey all 800 people in the senior class so they randomly select 150 people from the class and ask them their preference. the table shows the results.

using the sample results, estimate the proportion of the entire population that would like to take a cruise to bermuda.

A

Step-by-step explanation:

5 of the 150 want to take the cruise, so:

p = 5/150

p = 0.03

Answer A.

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
