Answer:
a₆ = 12
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₂ = 5 and a₁₀ = 19 , then
a₁ + d = 5 → (1)
a₁ + 9d = 19 → (2)
Subtract (1) from (2) term by term to eliminate a₁
8d = 14 ( divide both sides by 8 )
d = 1.75
Substitute d = 1.75 into (1)
a₁ + 1.75 = 5 ( subtract 1.75 from both sides )
a₁ = 3.25
Then
a₆ = 3.25 + 5(1.75) = 3.25 + 8.75 = 12
Answer:
Step-by-step explanation:
Given
Joaquin's score is
and Trisha's score is
Arranging score in order of value we get
Joaquin's :
Trisha's :
as no of values is even therefore their median is
Joaquin's
Trisha's
Therefore median of Joaquin's is lower
Thus Joaquin wins the game
Answer:
Step-by-step explanation:
Slope of perpendicular lines = -1
y = 5/2x + 3
-1 ÷
=
(-3 , -5)
Equation of the required line: y - y₁ = m(x -x₁)
y - [5] =
