14)NO..... -2x+5y=10.....-2(-3)+5(2)=10.....6+10 is not =10
15)YES......-2x+5y=10....-2(-10)+5(-2)=10.....20-10=10
16)YES......-2x+5y=10.....-2(5)+5(4)=10......-10+20=10
Had to look for the missing options and here is my answer.
Based on the study being conducted by Miranda which was covers students who would attend a students only school dance, the sample that is most likely going to give a representative sample for the poll would be "<span>twenty names from each grade pulled blindly from a container filled with the names of the entire student body </span><span>written on slips of paper." Hope this helps.</span>
12 *16 = 192
1/2 *20*10 = 100
192 +100 = 292 square units
Answer:
25 years
Step-by-step explanation:
To find the mean you need to find the sum of all numbers and divide by the number of terms there are.
In this case you would need to multiply the mean ages by the number of people used to find the mean:
35 * 3 = 105
23 * 12 = 276
Then add the total ages together:
105 + 276 = 381
Then divide by the number of total people in the office:
12 + 3 = 15
381/15 = 25.4
rounded to 25
