Santiago is trying to show his teacher why the product of two rational numbers is another rational number. His first steps are shown. Which is the best method Santiago
could use to continue?
Let m, n, p, and a represent integers.
By definition, and
are both rational
CLEAR
CHECK
Test with m = 1, n = 2.p = 3, and q = 4. Since and are
both rational, it is clear that the statement is true.
mx P = mxp
n 9 nxa
Show that mp and ng are both integers.
mx P = mxp
n 9 nxo
Since is rational and is rational, then
rational.
n
9
X
n
must be
9
Show that and are all integers.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

there will be 35 boys in each team. : )

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
