Sin 3pi/4 is angle 135 degrees or 45 degrees below 180 degrees. Hence it's opposite side is 1 and adjacent is 1, implying the hypothenus is sqrt(2). Hence
Sin 3pi/4 = 1/sqrt(2). Now multiply by sqrt(2)/sqrt(2) to get:
[1/sqrt(2).] * [sqrt(2)/sqrt(2)] = sqrt2)/2
She saves 1/10 of her salary. That's the simplified version, it can also be written 10/100. Fractions, decimals, and percentages are all interchangeable.
Answer:
1/18
Step-by-step explanation:
The probability of rolling a 1 is 1/6 because there are 6 numbers. You multiply that probability by the probability of getting a 2 or 3 which is 2/6 or 1/3 to get 1/18.
