0.016 as a fraction in simplest form
puteri [66]
0.016 as a fraction is 16/1000 and in simplest form it is 2/125.

An easy way to figure out the fraction of a decimal is by the decimal places. As we can see, there are four numbers in our decimal (0.016). 

The first decimal place = ones 
The second decimal place = tenths
The third decimal place = hundredths 
The fourth decimal place = thousandths

We stop at the thousandths place, so basically, take 16 and put it over 1000, which looks like 16/1000.

Answer:

There are 12 possible outcomes.

Step-by-step explanation:

This question represents combined independent events of probability.  Independent events are not affected by previous events.  So, your probability is the same with each flip of the coin or roll of the die.  So, you just have to look at the total number of outcomes for each and multiply them.  Since there are only two sides to a coin, there are only two total outcomes.  Since there are six sides to a die, there are only six total outcomes.  2 x 6 = 12 total outcomes.

What is the value of cose in the diagram below?
Nuetrik [128]

Answer:

cos \theta = 0.6

Step-by-step explanation:

Draw a line from point ( 0.6, 0.8 ) to the X - axis, forming a right triangle with hypotenuse = r = 1 , adjacent = 0.6,  opposite = 0.8

cos \theta = \frac{adjacent}{hypotenuse} , \ where  \  adjacent = 0.6 ,\  hypotenuse \  = r= 1

cos \theta = \frac{0.6}{1}\\\\cos \theta = 0.6\\\\\theta = cos^{-1} \ 0.6\\\\\theta = 53.13^\circ
