Average

In mathematics, everyone must have heard the term average in one place or other. Almost all types of calculation require taking out an average. In everyday life, the term is used for denoting a certain amount that can be said to be a typical quantity for multiple people or objects. In other words, if a group of people possesses a certain object, then the average gives us an idea regarding the quantity of the object possessed by each person. However, this is solely based on mathematical calculation. It is important to note that most people will not strictly have the average value in a group.

Please help me with number 4

4. Given the line pictured below, which of the following could be its equation?
(1) y = --x+8
(2) y = 2.x – 7
(3) y = --
x– 4
(4)

Expert Solution

Step 1

St. line:

4. y= $\frac{3}{2} x + 1$

2y-3x=2

we should find out the x-intercept and y-intercept of the above eq.

Step 2

$2 y - 3 x = 2 \frac{2 y}{2} - \frac{3 x}{2} = 1 \frac{y}{1} - \frac{x}{\frac{2}{3}} = 1 T h e x - i n t e r c e p t i s (- \frac{2}{3}, 0) a n d y - i n t e r c e p t i s (0, 1)$

As a result of urbanization, the temperatures in Paris have increased. In 1891 the average daily minimum and maximum temperatures were 5.8°C and 15.1°C, respectively. Between 1891 and 1968, these average temperatures rose 0.019°C/yr and 0.011°C/yr, respectively. Assuming the increases were linear, find the year when the difference between the minimum and maximum temperatures was 9C, and determine the corresponding average maximum temperature.
