Answer:
See below in bold.
Step-by-step explanation:
As we see from the diagram the x -intercept ( where the line intercepts the horizontal x-axis) is (3, 0) and the y-intercept is (0, -10).
A ratio is like a fraction, so since you are provided with the numbers its easy to put it into a ratio
depth is 3.8km
width is 7600km
ratio is 3.8:7600
Answer:
37
Step-by-step explanation:
Here, we have two different samples, hence, to obtain the confidence interval, we use the relation for the confidence interval for two sample means ;
(x1 - x2) ± Margin of error
Where, (x1 - x2) = point estimate of the sample mean, this is the difference in mean of the two samples.
From the question ;
x1 = 1150 ; x2 = 1113
Hence, the point estimate is : (1150 - 1113) = 37
