Answer:
The sampling technique used is convenience sampling.
Step-by-step explanation:
Convenience sampling technique is a method of non-probability sampling that is done using the most easiest sample or the most convenient sample.
For instance, sampling the people of our neighborhood, or school or company, etc.
This type of sampling is known as non-probability sampling because each individual\participant does not have a specific probability of selection. Whereas in case of probability sampling each participant has an equal probability of being selected.
Survey that are conducted through online portals or online survey use samples that are quite easy to collect. The sample collected through online surveys is convenience sample.
The survey conducted to determine how many people were in favor of stricter gun control uses a convenience sampling technique. As it uses the most easy source to collect the sample.
Thus, the sampling technique used is convenience sampling.
Answer:
2028 ft
Step-by-step explanation:
Let the feets of boards sold to get profit be x hence with the price of $1.13 which is inclusive of profit, the total sales will be 1.13 x
The cost per day will equally be the sum of variable cost which considers the feets of boards and the daily fixed charge. Considering the variable of $0.03 and fixed charge of $2230.80 then the equation is represented as 0.03x+2230.80
Relating the two equations then
1.13x=0.03x+2230.80 and rearranging like terms
1.13x-0.03x=2230.80
1.1x=2230.8
X=2230.8/1.1=2,028 ft
Therefore, to maximize daily profit, 2028 ft must be sold
Answer:
No solution
Step-by-step explanation:
y=x-1 and y-x=-9
1st make sure both equations are in slope intercept form
since the 2nd equation isn't, you change it by adding x to both sides and rewrite it as y=mx+b so
y-x=-9
+× +×
y=×-9
now you have y=x-1 and y=x-9
substitute the y with the other equation
x-1=x-9
subtract x from both sides since you can't have the variable on both sides
now you've got -1 = -9
and since that equation isn't true, it has no solution.
Answer:
d)
true
Step-by-step explanation:
- x - 4y = - 10
x + 4y - 10 = 0
a)
3 + 4×2 - 10 = 0
3 + 8 - 10 = 0
11 - 10 ≠ 0 (false)
b)
- 3 + 4×3 - 10 = 0
12 - 3 - 10 = 0
12 - 13 ≠ 0 (false)
c)
false
d)
true
