What kind of trend does the scatter plot show? Describe a real-life situation that the scatter plot could represent. => No trend; Age of students vs. number of pets they have or Positive trend; Age of car vs. its value or Negative trend; Age of car vs. its value..

What kind of trend does the scatter plot show? Describe a real-life situation that the scatter plot could represent. => Positive trend; Age of students vs. Number of siblings they have or Negative trend; Age of students vs. Their height or No trend; Age of students vs. Number of..

The union of the set of rational numbers and irrational numbers forms the set of real numbers. (i) For every real number, there is a corresponding point on the number line. (ii) For every point on the number line, there exists a real numbe..

The mean life span of an electric bulb is 350 hours, with a standard deviation of 10 hours. A random sample 40 of a particular brand of electric bulbs is taken and found that their mean life span was 348 hours. State the null hypothesis( H o ) for the situation. => H o..

Order the real numbers 4, 7, - 1 and - 8 using number line. => - 8 < - 1 < 7 < 4 or - 8 < - 1 < 4 < 7 or - 1 < - 8 < 4 < 7 or - 8 < 4 < - 1 < 7..

These are commonly used in power distribution (at low frequencies) and in communications (at high frequencies). Biodiversity is most simply defined as the variety of life and its processes. A transmission line may be defined as a device for transmitting or guiding energy from o..

The local authorities in a certain city install 1600 electric lamps in the streets of the city. If the lamps have a mean life rate of 1000 burning hours, with a standard deviation of 150 hours, approximately what number of lamps might be expected to fail in first 750 burning hours? Assume..

Let the lines be Let P (h,k) be the point of intersection of L 1 = 0 and L 2 = 0. Now consider the following equations, (v) (vi) This equation is a first degree in x and y and hence this represents a straight line. Again, from (iii) and (iv), the coordinates (h,k) sa..

are the two straight lines represented by (1). These two equations are of the form y = m 1 x and y = m 2 x and therefore the given equation represents two straight lines through the origin. The two straight lines are real, coincident or imagina..

Compare the real numbers 0.45 and 2 3 using number line. => 0.45 < 2 3 or 0.45 = 2 3 or 0.45 > 2 3 or None of the above..
