Oksana_A [137]

Answer:

7%

Step-by-step explanation:

(15/220) x 100 = 6. 8182 = 7%

to convert to percentage multiply by 100

To convert to the nearest whole number, look at the first number after the decimal. If it is greater or equal to 5, add 1 to the number after the decimal. 8 is greater than 5, so add one to 6

In your top dresser drawer are 6 blue socks and 10 grey socks, unpaired and mixed up. One dark morning you pull two socks from t
pishuonlain [190]

Answer:

D) 0.500

Step-by-step explanation:

Blue Socks = 6

Grey socks = 10

Probabilities to find :

Since there are a total of 16 socks, the probability of both socks being blue is  

Probability(blue) = (\frac{6}{16} ) \frac{5}{15} =\frac{30}{240} =\frac{1}{8}

The probability of both being grey is  

Probability(grey)  =(\frac{10}{16} ) \frac{9}{15} =\frac{90}{240} =\frac{3}{8}

(Note: After 1 sock is picked , next sock drawn would have a different probability as 1 sock is already picked so it would be 1 minus the total socks available of that color)

The probability two socks match:

Probability(blue) + Probability(grey) = \frac{1}{8} + \frac{3}{8}  = \frac{4}{8}  =\frac{1}{2} = 0.500

vodomira [7]

Answer:

x = 25.8^{o} and y = 51.4^{o}

Step-by-step explanation:

Known that he sum of angles on a straight line is 180^{o}. From the diagram;

2y + x + y = 180^{o}

x + 3y = 180^{o} ................ 1

Also,

2x + x + 2y = 180^{o}

3x + 2y = 180^{o} .............. 2

Using the elimination method, multiply equation 1 by 3 and equation 2 by 1

3x + 9y = 540 ............ 3

3x + 2y = 180^{o} ............. 4

7y = 360

y = \frac{360}{7}

y = 51.4^{o}

substitute the value of y in equation 1,

x + 3y = 180^{o}

x + 3(51.4) = 180^{o}

x + 154.2 = 180^{o}

x = 180^{o} - 154.2

x = 25.8^{o}

Thus, x = 25.8^{o} and y = 51.4^{o}
