Answer:
Step-by-step explanation:
a₁₂ = a₅ + (12-5)d
72 = 23 + 7d
d = 7
a₃ = a₅ + (3-5)d = 23 - 2⋅7 = 9
a₂ = a₃ - d = 9-7 = 2
a₁ = a₂ - d = 2 -7 = -5
Answer:
75
Step-by-step explanation:
5(6+9)
Times the five by the numbers in the bracket
30 + 45
= 75
If you substitute X and y for 3 and 6 you get
6 <7
so the answer is YES
Answer:
the slope for y = 3 is 0.
Step-by-step explanation:
Answer:
0.91.
Step-by-step explanation:
We use the formula:
P(a U b) = p(a) + p(b) - p (a ∩ b) where P(a U b) is p(a or b) and p (a ∩ b) is p (a and b).
So p(a or b) = 0.78 + 0.66 - 0.53
= 0.91.
