Answer:
24 cm
Step-by-step explanation:
The photo was 6 cm wide, and was made into 18 cm wide. Divide 18 with 6:
18/6 = 3
To solve for the length enlargement, multiply 3 with the length, or 8 cm:
8 x 3 = 24
24 cm is the length of the enlargement.

Answer:
Error Bound = 0.04
Step-by-step explanation:
Whenever we want to estimate parameter from a subset (or sample) of the population, we need to considerate that your estimation won't be a 100% precise, in other words, the process will have a random component that prevents us from always making the exact decision.
With that in mind, the objective of a confidence interval is to give us a better insight of where we expect to find the "true" value of the parameter with a certain degree of certainty.
The estivamative of the true difference between proportions was -0.19 and the confidence interval was [-0.23 ; -0.15].
The question also defines the error bound, as the right endpoint of the confidence interval minus the sample mean difference, so it's pretty straight foward:
Error Bound = 
The interpretation of this would be that we expect that the estimative for the difference of proportions would deviate from the "true" difference about
or 4%.
Answer:
Step-by-step explanation:Yes they both do, If u get the the number from the y-intercept and put it in the graph. and then get the slope if it is a decimal (Rise/Run) Put it in the then you have the answer
