Answer:

0.5amps

Step-by-step explanation:

I is inversely proportional to resistance

I = k/R

k = I/ R

k = 20/5

k = 4

This means that, I = 4/R

So, when R = 8ohms,

I = 4/8

=0.5amps

A bag contains 3 red, 6 blue, 5 purple, and 2 orange marbles. One marble is selected at random. What is the probability that the

mamaluj [8]

Answer:

$P(blue)=37.5\%$

Step-by-step explanation:

-Probability is the likelihood of an event occurring.

-The total number of events is:

$Total=3+6+5+2\\\\=16$

-The total number of blue events is:

$Blue=6$

#Probability of a blue is thus calculated as:

$P(Blue)=\frac{Blue}{Total}\\\\=\frac{6}{16}\\\\=0.375\\\\=37.5\%$

Hence, the probability of choosing a blue marble at random is 37.5%
