This is an inappropriate conclusion because of <u>D. At 10 months</u>, ninety percent of toddlers have not reached the developmental milestones to walk.

<h3>What is an inappropriate conclusion?</h3>

An inappropriate conclusion is one arrived at without a proper research design.  An inappropriate conclusion can also be reached when the interpretation of the research result is not based on the findings.

Our conclusion implies that there is a wrong interpretation of the research findings because of the researcher's bias.

Thus, the research conclusion is <u>inappropriate</u> because of Option D.

The size of a TV is measured by its diagonal. You want to buy a TV that has a 32-inch screen and a height of 15.7 inches. What i
MrRissso [65]
Think of the space created with the diagonal line like a triangle. There are three sides. the longest side, the diagonal line is 32 inches. one of the other sides is 15.7 inches. Using Pythagoras theorem, we know that a^2 + b^2 = c^2, where c is the longest side of the triangle (32inches) and either a or b is 15.7inches. let's say that a is 15.7 inches. if we substitute these values we just assigned to a and c into Pythagoras' theorem above, we get 15.7^2 +b^2 = 32^2. we can simplify this to 246.49 + b^2 = 1024. We then subtract 246.49 from both sides of the equation to get b^2 = 777.51. we then square root both sides of the equation to get b = 27.88 (rounded to 2 decimal places). because b is the width of the TV, the width of the TV is 27.88 inches.
{a}^{2}  +  {b}^{2}  =  {c}^{2}  \\  {15.7}^{2}  +  {b}^{2}  =  {32}^{2}  \\ 246.49 +  {b}^{2}  = 1024 \\  {b}^{2}  = 777.51 \\ b =  \sqrt{777.51}  \\ b = 27.88

Is dot multiplication easier than cross multiplication?
spayn [35]

<em>☽------------❀-------------☾</em>

<em>Hi there!</em>

<em>~</em>

<em>This question struck a chord with me as a highscooler. I never refer to the symbol x as an operator for multiplication because it too closely resembles a variable x. I only use a dot while indicating multiplication of two real numbers. Once students reach Algebra, the need for that is also limited.As far as the history goes, here's what I found: “Today elementary school students use the symbol × for multiplication. William Oughtred (1574-1660), a clergyman who gave free private lessons to pupils interested in mathematics, used the symbol × for multiplication. He also invented 150 other symbols. The × symbol was not readily accepted though. Gottfried Wilhelm Leibniz (1646-1716) thought it resembled the unknown x too much. Thomas Harriot (1560-1621) used the dot (·) for multiplication. This was not used much either until Leibniz adopted it.” It's no surprise that Leibniz was instrumental in the popularization of this notation, as much of the notation we use in Calculus was also developed by Leibniz. In short, there is no difference. Multiplication is a natural operation in mathematics and has just been symbolized in different people in different ways in different periods of time.</em>

<em>Hence they are both easy to use.</em>

<em>❀Hope this helped you!❀</em>
