Answer:
(48.3875, 51.6125)
Step-by-step explanation:
At 99% level of significance
From the normal standard deviation table 
Considering that
± 
=50±
50±2.33(0.625)=50±1.6125=(48.3875, 51.6125)
Therefore, there’s 99% confidence that the mean lifetime of a certain brand of tires is between 48.3875 and 51.6125
Answer:
It would be the first graph, because if you look at the points on your graph the first one is (0,1), the the next one is (5,2), and so on so forth, that makes your answer the first graph, because that table is showing you the points that are marked
Step-by-step explanation:
Hi there!
So, let’s start with the rectangles. You would multiply 4(2 ft x 3 ft) since length x width = area (for rectangles). You multiply by 4 because there are 4 rectangles mentioned, and each have the same 2 ft x 3 ft measurements.
Next, you multiply 2(2 ft x 2 ft), or 2 to the exponent of 3, i.e., 2^3. 2 ft x 2 ft are the measurements of the sides of the squares, and as you probably know, side x side OR side^2 = area (for squares). Again, you multiply the original 2 ft x 2ft area by 2 because there are 2 squares mentioned with the same 2 ft x 2 ft measurements.
Finally, you add 4(2 ft x 3 ft) and 2(2 ft x 2 ft) together to equal the total area of plywood purchased, or the total amount of square feet of plywood he is purchasing in all.
