Answer:
9, 16, 23, 30
Step-by-step explanation:
The arithmetic means are the terms of an arithmetic sequence, that is
2, a₂, a₃, a₄, a₅, 37
The nth term of the sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and a₆ = 37 , that is
a₁ + 5d = 37
2 + 5d = 37 ( subtract 2 from both sides )
5d = 35 ( divide both sides by 5 )
d = 7
Then
a₂ = a₁ + 7 = 2 + 7 = 9
a₃ = a₂ + 7 = 9 + 7 = 16
a₄ = a₃ + 7 = 16 + 7 = 23
a₅ = a₄ + 7 = 23 + 7 = 30
The 4 arithmetic means between 2 and 37 are 9, 16, 23, 30

Step-by-step explanation:
Consider the provided information.
For the condition statement or equivalent "If p then q"
The rule for Contrapositive is: Negative both statements and interchange them.
Part (A) If you are taller than 6 ft, then it is unpleasant for you to travel in economy class.
Here p is "you are taller than 6 ft, and q is "it is unpleasant for you to travel in economy class".
It is given that Your contrapositive must not contain explicit references to negation. Assume that the negation of "unpleasant" is "pleasant".
Contrapositive: If it is pleasant for you to travel in economy class then you are not taller than 6 ft then.
Part (B) "If x ≥ 0 and y ≥ 0 then xy ≥ 0" where x, y are real numbers.
Here p is "xy≥ 0, and q is "x ≥ 0 and y ≥ 0"
The negative of xy≥ 0 is xy<0, x ≥ 0 is x<0 and y ≥ 0 is y<0.
Remember negative means opposite.
Contrapositive: If xy < 0 then x<0 and y<0.
Answer:
100 is correct answer
Step-by-step explanation:
when ever anything ² , it means that number is multiplied by itself.
in above we multiple 10 with 10 and we get 100.
hope it helped you:)
