suppose a = {2,5,7,9,13, 25, 26).
(a) find n(a).
n(a) =
(b) t/f: 7. a

a)   n (A) = 7

Step-by-step explanation:

Here, set A =  {2,5,7,9,13, 25, 26)

Noe, for any set A,

n (A) is defined as he total number of elements in the set A.

or, n(A) = CARNALITY OF SET A

Here,the number of elements in set A = 7

⇒ n (A) = 7

if this is really you s much. i only have 3 points left and i have 2 questions to ask

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
