Hope this helps :D
that would be 48/9 because it would be kittens(48) to puppies(9) then simplified to 16/3.
That's a vertical line, no slope, so no y=something.
Answer: x = -9
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
