a(1) = 3(1)-1 = 3-1 = 2

a(2) = 3(2)-1 = 6-1 = 5

a(3) = 3(3)-1 = 9-1 = 8

So, the sequence would be 2,5,8,11....

sweet [91]

Answer:

$1000

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

then, solving our equation

I = 1000 × 0.03 × 5 = 150

I = $ 150.00

The simple interest accumulated

on a principal of $ 1,000.00

at a rate of 3% per year

for 5 years is $ 150.00.

Please give answer ??
krok68 [10]

Answer:

21.5%

Step-by-step explanation:

The area of the 4 circles together = 4×π×12^2

The area of the square = 48^2

then the probability that the point is in one of the circles =

(4×π×12^2)÷48^2

=0.785398163397

Therefore, the probability that the point is not in a circle =

1 - 0.785398163397 = 0.214601836603

converted into percentage : 21.4601836603

rounded = 21.5%

Carpet costs $21.95 per square yard and the padding to put under it costs $2.55 per square yard. Felix plans to install padding
marusya05 [52]

Answer:

$1679.175 or $1679.18

Step-by-step explanation:

split the carpet into rectangles to make it easier to look at

one rectangle is 2 yards in height and 9 yards in width (5 yards plus 4 yards)

area of a rectangle = (w)(h), so 9 x 2 = 18 yards in area.

second triangle is 4 yards in width, and 3 yards in height.

area of a rectangle = (w)(h), so 4 x 3 = 12 yards in area.

Total area = 30 yards

30(21.95)(2.55) = $1679.175 or $1679.18

The two tires on a bicycle experience wear much like car tires do; repeated contact with the road or sidewalk will wear down the
PSYCHO15rus [73]

Answer:

Each bike with both types of tire.

Half of the tires of each type will be in the front wheel and the other half in the rear wheel.

Step-by-step explanation:

To compare the wear of each type of tire in a matched-pair test, the individuals have to test each of the tires in the same conditions.

This will allow to compare the tires wear in equal conditions. If the tires are assigned randomly to the volunteers, there will be difference in the wear due to difference habits of the bikers.

The only way to implement a matched-pair test with bikes is to use one type of tire in the front wheel and the other type in the rear wheel. Half of the tires of each type will be in the front and half in the rear.

In this way, the distance traveled with each type of tire will be the same.
