This would result in a biased sample because:
- the survey is surveying elementary kids about a new youth center
most of those kids are more likely than not to want a youth center, so most of them will naturally agree without a doubt for the need of a youth center
- Even the adults at the elementary school are more likely than not to agree with a new youth center because they are teachers and can even benefit from working at the youth center
- in final words the reason why this survey will be biased is because there is no variety in the participants being tested. It is basically just asking teachers she students their preference, excluding the rest of an entire community

105.91 is the answer for you
Area are all sides multiplied the formula can be found online
Answer:
m = -5.3
Step-by-step explanation:
-39.75 = 7.5m
Divide both sides by 7.5 to get m alone
-39.75/7.5 = 7.5m/7.5
-5.3 = m
Hope this helps:)
1. You have that:
- Each gallon of paint covers 400 ft²<span>.
- One side of a wall must be painted and its dimensions are :is 8 meters tall and 40 meters long.
1 ft=0.3048 m
1 ft</span>²=(0.3048 m)²=0.09290 m²
2. Each gallon of paint covers 400 ft<span>², then:
</span>
400 ft²x<span>0.09290=37.16 m</span>²
3. The area of one side of the wall is:
A=8 mx40 m
A=320 m²
4. Therefore, you have:
1 gallon-----37.16 m²
x-----320 m²
x=320x1/37.16
x=8.61 gallons
x≈9 gallons
The answer is: 9 gallons
