Answer:
a=12
Step-by-step explanation:
a/40=3/10
10 x 4=40, so
3 x 4=12
a=12
1/6th is the answer in simplest form.
The Arithmetic Mean and Median of the given set of data ( 2, 5, 13, 15, 19, 21 ) are 12.5 and 14 respectively.
<h3>What is Arithmetic mean?</h3>
Arithmetic mean is simply the average of a given set numbers. It is determined by dividing the sum of a given set number by their number of appearance.
Mean = Sum total of the number ÷ n
Where n is number of numbers
Median is the middle number in the data set.
Given the sets;
Mean = Sum total of the number ÷ n
Mean = (2 + 5 + 13 + 15 + 19 + 21) ÷ 6
Mean = 75 ÷ 6
Mean = 12.5
Median is the middle number in the data set.
Median = ( 13 + 15 ) ÷ 2
Median = 14
Therefore, the Arithmetic Mean and Median of the given set of data ( 2, 5, 13, 15, 19, 21 ) are 12.5 and 14 respectively.

Answer:
1000
Step-by-step explanation:
10 x 100 = 1000. 1000^7 / 1000^6 = 1000^1... 1000 to the 1st power is itself.
In the beginning operations are performed with multiplication,,,so
100x100=10.000+100=
10.100result…
