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
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) = 
The probability of both being grey is
Probability(grey) =
(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) =
+
=
=
= 0.500

Answer:
x =
and y = 
Step-by-step explanation:
Known that he sum of angles on a straight line is
. From the diagram;
2y + x + y = 
x + 3y =
................ 1
Also,
2x + x + 2y = 
3x + 2y =
.............. 2
Using the elimination method, multiply equation 1 by 3 and equation 2 by 1
3x + 9y = 540 ............ 3
3x + 2y =
............. 4
7y = 360
y = 
y = 
substitute the value of y in equation 1,
x + 3y = 
x + 3(51.4) = 
x + 154.2 = 
x =
- 154.2
x = 
Thus, x =
and y =
