Answer:

x coordinate is negative

y coordinate is positive

Step-by-step explanation:

We know that

\pi=180

Hence

\frac{3\pi}{4}=\frac{3*180}{4}

\frac{3\pi}{4}=3*45=135

Hence our angle lies in the second quadrant. Second quadrant is enclosed by the negative x axis and positive y axis.

In second quadrant, we have negative value if x coordinate and positive value of y coordinate.

3pi/4 is 135 in degrees.  A 135-degree angle lies in quadrant 2.  In quadrant 2, the x values are negative and the y values are positive.

For a certain​ candy, 20​% of the pieces are​ yellow, 15​% are​ red, 20​% are​ blue, 20​% are​ green, and the rest are brown. ​a
OLEGan [10]

Answer:

Step-by-step explanation:

Based on the question we are given the percentages of each of the types of candies in the bag except for brown. Since the sum of all the percentages equals 75% and brown is the remaining percent then we can calculate that brown is (100-75 = 25%) 25% of the bag. Now we can show the probabilities of getting a certain type of candy by placing the percentages over the total percentage (100%).

  • Brown: \frac{25}{100}
  • Yellow or Blue: \frac{20}{100} +\frac{20}{100} = \frac{40}{100}  ....add the numerators
  • Not Green:  \frac{80}{100}.... since the sum of all the rest is 80%
  • Stiped:  \frac{25}{100} .... there are 0 striped candies.

Assuming the <u><em>ratios/percentages</em></u> of the candies stay the same having an infinite amount of candy will not affect the probabilities. That being said in order to calculate consecutive probability of getting 3 of a certain type in a row we have to multiply the probabilities together. This is calculated by multiplying the numerators with numerators and denominators with denominators.

  • 3 Browns: \frac{25*25*25}{100*100*100} = \frac{15,625}{1,000,000} = \frac{1.5625}{100}

  • the 1st and 3rd are red while the middle is any. We multiply 15% * (total of all minus red which is 85%) * 15% like so.

\frac{15*85*15}{100*100*100} = \frac{19,125}{1,000,000} = \frac{1.9125}{100}

  • None are Yellow: multiply the percent of all minus yellow three times.

\frac{80*80*80}{100*100*100} = \frac{512,000}{1,000,000} = \frac{51.2}{100}

  • At least 1 green: multiply the percent of green by 100% twice, since the other two can by any

\frac{20*100*100}{100*100*100} = \frac{200,000}{1,000,000} = \frac{20}{100}

What set of lengths forms a right triangle?
Leni [432]
The answer is C. 50 in, 48 in, 14 in

In a right triangle, a² + b² = c², where c is the longest side (hypotenuse), a and b are the other two sides.

14² + 48² = 196 + 2304 = 2500
50² = 2500
