The table below shows the number of cars Jing sold each month last year.

ella [17]

Answer:

The median of the data in the table is 19.

Step-by-step explanation:

We are given the following data that shows the number of cars Jing sold each month last year below;

Number of cars Jing sold: 13, 16, 19, 20.5, 23.5

For calculating the median, firstly we have to observe that the number of observations (n) in our data is even or odd because;

If n is odd, then the formula for calculating median is given by;

Median = $(\frac{n+1}{2} )^{th} \text{ obs.}$

If n is even, then the formula for calculating median is given by;

Median = $\frac{(\frac{n}{2} )^{th} \text{ obs.} + (\frac{n}{2}+1 )^{th} \text{ obs.} }{2}$

Here, the number of observations in our data is odd, i.e. n = 5.

So, Median = $(\frac{n+1}{2} )^{th} \text{ obs.}$

= $(\frac{5+1}{2} )^{th} \text{ obs.}$

= $(\frac{6}{2} )^{th} \text{ obs.}$

= 3rd obs. = 19

Hence, the median of the data in the table is 19.

1. Determine the variables in the figure below. 20 50

Marina CMI [18]

Answer:

r=8

t=4√29

Step-by-step explanation:

By the altitude leg theorem:

${20}^{2} = 50r$

This implies that:

$r = \frac{20 \times 20}{50}$

We simplify to obtain:

$r = 4 \times 2 = 8$

By the Pythagoras theorem:

${t}^{2} = {20}^{2} + {8}^{2}$

${t}^{2} = 400 + 64$

${t}^{2} = 464$

$t = \sqrt{464}$

$t = 4 \sqrt{29}$
