Answer:
4
Step-by-step explanation:
The equation is 2(10+x)=28 where x is the unknown number we are trying to find. Use distrubutive property to combine like terms. 2 times 10 is 20 and 2 times x is 2x. Now we have 20+2x = 28. What you do to one side you must do to the other. 20 minus 20 is 0. 28 minus 20 is 8. Now our equation is 2x is 8. To find 1 x we divided in half. 8/2 is 4 therefore the missing variable is 4.

Answer:
Step-by-step explanation:
Plug×=0 into the equation and solve for y.
If 12 students make up 24% of the population, 1 student is 2% of the population because 24/12=2
100/2%=50
I did this because the population would be 2% times # of students= 100%
divide 100 by 50 to get 2 percent or 100/ 2 percent to get 50 students
<h3>
Answer: 0.29</h3>
Explanation:
We ignore the first row, and focus on the second row only, because we're told that they did not stay at the beachfront resort.
We have 0.05 of the entire sample visit St Lucia in the second row out of 0.17 total for that row. This leads to 0.05/0.17 = 0.29 approximately. There's roughly a 29% chance of someone visiting St Lucia given they stayed in a condo.
If you wanted, you can move the decimal point 2 spots to the right for every value in the table. That would mean of the 17 people who stayed in a condo, 5 of them visited St Lucia. So 5/17 = 0.29
