The sample is large enough, representative of the entire population, and chosen randomly so the conclusion is valid.
Answer:
It will take 1 5/7 hours
Step-by-step explanation:
3/4 of an hour is;
3/4 * 60 minutes = 45 minutes
3 1/2 acres is done in 45 minutes
8 acres will be done in x minutes
Thus, mathematically;
3 1/2 * x = 8 * 45
7x/2 = 360
7x = 2 * 360
7x = 720
x = 720/7 minutes
Let us convert this to hours
That will be;
720/7/60 = 720/(60 * 7) = 720/420 = 12/7
= 1 5/7 hours

Answer: a) What is a good scale to use for the y axis? -20 units.
(b) What is a good interval to use for the y axis?- 20 units
Step-by-step explanation:
A family is tracking its spending habits. Over the
past year, the grocery bill has ranged from $120 to $180.
We need to plot these points on a coordinate grid.
If we plot the grocery bills along the y-axis, and past years will be plotted along the x-axis.
So, a) Good scale to use for the y-axis will be
1 scale = 20 units
As 120 and 180 are both divisible by 20.
So, it will be a good scale to use for the y-axis.
b) Good interval to use for the y-axis:
It will be again of 20 units.
