Answer:
Step-by-step explanation:
The numbers don’t increase by a constant amount, so this is not an arithmetic sequence.
It appears to be a <em>geometric sequence</em>.
The <em>general formula</em> for each term in a geometric sequence is
aₙ = a₁rⁿ⁻¹
===============
Calculate the value of r
You can calculate the r-value by dividing any two consecutive terms in the sequence.
rₙ = aₙ/aₙ₋₁
a₂/a₁ = 4.5/3 = 1.5
a₃/a₂ = 6.75/4.5 = 1.5
a₄/a₃ = 10.125/6.75 = 1.5
a₅/a₄ = 15.1875/10.125 = 1.5
r = 1.5
===============
Determine the formula for the nth term
a₁ = 3; r = 1.5 Substitute the values
aₙ = 3(1.5)ⁿ⁻¹ Write the equation as a function of x
Answer:
0.08 or 8%
Step-by-step explanation:
to find probability, number of left handed/total
this would be (9+3)/(90+60), which simplifies to 12/150 = 0.08.
I hope you understand my work goodluck :)
i give the answer here
The best answer to the question you have given above would be letter A. In an isometric transformation, the preimage and image must not change size. You are free to rotate the image, preserve angle measure, and reflect it across the axis, but it should be the same size.
Well, 8 plus 7 equals 15 and 15 doubled (multiplied by 2) is 225.
I hoped this helped :)
