Selecting a green marble: 3/20
Selecting a yellow marble: 8/20
Answer:
Step-by-step explanation:
Plug in x = 2
g(2) = 3(2)² - 2*2 + 5
= 3* 4 - 4 + 5
= 12 - 4 + 5
= 8 + 5
= 13
Answer:
Yes 4
Step-by-step explanation:
6.75 because 6 is the whole number so it won't change and if you do 3 divided by 4 you get .75
Answer:
324 and 144
Step-by-step explanation:
We require
a₁, a₂, a₃, a₄
where a₂ and a₃ are the required geometric means
The n th term of a geometric sequence is
= a₁
where a₁ is the first term and r the common ratio
Here a₁ = 729 and a₄ = 64, thus
729(r³) = 64 ( divide both sides by 729 )
r³ = ( take the cube root of both sides )
r = = , then
a₂ = 729 × = 81 × 4 = 324
a₃ = 324 × = 36 × 4 = 144
Thus
729, 324, 144, 64
