Javier made a scatterplot to show the data he collected on the growth of a plant.

Leya [2.2K]

Answer:

The answer is C i.e y = 3.25 x + 4.60

Step-by-step explanation:

Given the graph in which the Javier made a scatter plot to show the data he collected on the growth of a plant.

Now, we have to choose the equation which best represents Javier's data.

The graph shown does not pass through origin therefore intercept can not be equal to 0. hence solution A discarded.

The graph of rest of three solutions attached and the points which shown in the graph match to the points on the graph of solution third as shown. Hence, The answer is C i.e y = 3.25 x + 4.60

Make a box and whiskers plot of the data. average temperature in Pittsburgh in June 79,70,73,84,83,88,75,72,76,68,68,79,84,74,75

aliya0001 [1]

The box-and-whisker plot is attached.

We first order the data from least to greatest:
67,68,68,69,70,72,73,74,75,75,76,78,79,79,80,83,84,85,85,88

Now we find the median. Since there are 20 data values, the median is between 75 and 76:
(75+76)/2 = 151/2 = 75.5

Now we find the Lower Quartile (LQ). We do this by finding the median of the lower half of data (from the median down). There are 10 values here; the median is between 70 and 72:
(70+72)/2 = 142/2 = 71

Find the Upper Quartile (UQ). Do this by finding the median of the upper half of data (from the median up). There are 10 values here; the median is between 80 and 83:
(80+83)/2 = 163/2 = 81.5

The middle bar of the box is over the median. The left hand side of the box is over LQ, and the right hand side of the box is over UQ. Now we draw a whisker from the box to the highest value, 88, and from the box to the lowest value, 67.
