Answer:

0.316

Step-by-step explanation:

Probability = (number of outcomes)/(total number of outcomes)

In this case,

the total number of outcomes is 6+5+8 = 19, and

the number of outcomes for getting a blue pen = 6

Hence,

P(blue) = 6/19 = 0.31578947368 ≈ 0.316

Hope this helps and be sure to have a wonderful time ahead at Brainly! :D

Answer:D

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 8.5%/100 = 0.085 per year

putting time into years for simplicity

6 months ÷ 12 months/year = 0.5 years

then, solving our equation

I = 10000 × 0.085 × 0.5 = 425

I = $ 425.00

on a principal of $ 10,000.00

at a rate of 8.5% per year

for 0.5 years (6 months) is $ 425.00
