How many mor barrel of gasoline than diesel were produced last year

algol [13]

Answer:

3 million barrels

Step-by-step explanation:

Total crude oil=60 million barrels

gasoline 34% diesel 29% total crude oil -60 million barrel · =0.34 times 60

Diesel=20,400,000 and gasoline=17,400,000

Quantity of gasoline = 34% of total crude oil

=0.34 times 60 =20.4

Quantity of diesel = 29% of total crude oil

=0.29 times 60 { million barrels}

Clearly, Quantity of gasoline is more than Quantity of diesel

difference = Quantity of gasoline-Quantity of diesel

20.4 -17.4 milion barrels

Therefore,

The production of gasoline is 3 million barrels more than diesel last year.

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.
