Answer:
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
Answer:
1/96 or 0.01041666667
Step-by-step explanation:
3.2 is the Length of y 7.5 is the length of z and the length of x is 12.5
X=4, y=28. 7x=2x+20, so subtract 2x from both sides and you’ll get 5x=20. Divide both sides by 5 and you’ll get x=4. Substitute this into the other equations and they will both equal 28.
