Answer: 112 square feet
Step-by-step explanation:
(4*10)+(18*4)= 40+72=112
Answer:
43/70
Step-by-step explanation:
Total number of times spun = 14 + 12 + 16 + 15 + 13 = 70
Total number of times spun that yielded a odd number (1,3,5) = 14 + 16 + 13 = 43
The probability of spinning an odd number = total number of spins that yielded 1,3,5 ÷ total number of spins yielding all values from 1 to 5
= 43 / 70
Answer:
The result will be inaccurate.
Step-by-step explanation:
A landscaper wants to find the answer to the question “How much time do people in Raleigh, North Carolina, spend doing yard work in one week?”
He asks the owners of all 120 houses in a Raleigh neighborhood.
The results of such a survey can never be accurate.
Firstly, the sample is not random as the person selected all the 120 houses in the neighborhood.
Secondly, few samples do not represent a large population. The city must have many lawns and the lawns of a single area does not denote the lawns of the entire city.
So, the results will be inaccurate.
Answer:
No
There are infinitely many solutions to the system.
{36x+21y=24312x+7y=81
Multiply the second equation by 3.
3(12x+7y36x+21y=81)=243
Subtract this new equation from the first equation.
36x+21y−(36x+21y0+0=243=243)=0 true
