HELP ME Which two changes to the can opener would increase its mechanical efficiency? A shorten the paddle so that they are closer in size to the axle that they turn B grease the rotating wheel of the opener so that there is less breaks in between moving parts C replaced it with a straight handle the act as levers with shorter pieces of metalD sand the cutting surface of the metal piece so that it is perfectly smooth and sharp whats the correct ordered pair for, x+y=12 and -x=-y-10 Which function shows a fabric with a price of $1.25 per square yard?A table showing Price of Fleece with five columns and two rows.

Express (root 19 - root 7)(root 19 + root 7) in simplest form. In a right triangle, two sides are 12 and 13. Find the measure of the third side. Consider all cases Find the area of the shaded region.

Hurricanes and other extreme weather will increase B. Most crops will grow better in warmer climates C. Sea levels will drop all around the world D. Disease will not be able to spread as quickly What's is biosynthesis Which of the following is a characteristic of the plasma membrane?To protect the cell's internal contents, water is the only substance that can freely pass through the plasma membrane.Only small molecules are allowed into and out of the cell by the plasma membrane.Its selective permeability allows certain molecules, such as oxygen and carbon dioxide, to flow freely in and out of the cell while controlling the flow of other molecules.The structure of the phospholipids forms a stiff protective outer shell around the cell's internal contents. 18) Both x and y coordinates of a point in quadrant 1 are negative. Quantitative noninvasive techniques are needed for routinely assessing symptoms of peripheral neuropathies, such as carpal tunnel syndrome (CTS). An article reported on a test that involved sensing a tiny gap in an otherwise smooth surface by probing with a finger; this functionally resembles many work-related tactile activities, such as detecting scratches or surface defects. When finger probing was not allowed, the sample average gap detection threshold for m = 8 normal subjects was 1.71 mm, and the sample standard deviation was .53; for n = 10 CTS subjects, the sample mean and sample standard deviation were 2.53 and .87, respectively. Required:a. Does this data suggest that the true average gap detection threshold for CTS subjects exceeds that for normal subjects? b. State and test the relevant hypotheses using a significance level of 0.01. 1+12+3+583+2/38+1+1+4=?
