Answer:

AXB={(0,a), (0,n), (0,t), (w,a), (w,n), (w, t)}

BXA={(a, 0), (a, w), (n, 0), (n, w), (t, 0), (t, w)}

Step-by-step explanation:

First, you take the first element of set A (0) as the first coordinate and then you take the first element of set B (a) as your second coordinate. The first pair of AxB would be (0,a).

Then you pair the first element of A with the second element of B. Then the first element of A with the third of B.

After that you pair the second element of A with all the elements of B and finally you pair all elements of A with all elements of B. Finally you check that all pairs that are repeated. You just write one for any repeated pair.

A teacher collects data on the number of hours, s, his students spend studying and the number of hours, t, they spend watching T
Sidana [21]
Since there is a negative correlation, evident by the negative slope of the equation of the line given to be -0.5, if we take t as 0, we get an equation of,
                                            s = 3.6
This means that if a student does not watch television, he or she spends a maximum of 3.6 hours studying.

A boy has twice as many nickels as he has pennies, and he has 5 less dimes than nickels. If he has $4.46 in all, how many coins
Zarrin [17]
N=2p
n/2=p

n-5=d

10d+5n+1p=446
subsitute n/2 for p
subsitute n-5 for d
10(n-5)+5n+n/2=446
times 2 both sides
20(n-5)+10n+n=892
expand
20n-100+10n+n=892
31n-100=892
add 100 both sides
31n=992
divide both sides by 31
n=32

subsitute back

n/2=p
32/2=16=p


n-5=d
32-5=d=27


27 dimes
16 pennies
32 nickles
