P would then equal (-4,7) after the reflection
Don’t let R confuse you as it stands for Reflection. In this question you want to do a reflection across the y-axis.
The formula for reflection across the y-axis is (-x,y). In meaning as you cross the y-axis you y-value will always stay the same while your x-value with the opposite of what it is currently.
With that being said you want to plug in your values from point P to the formula which will leave you with (-4,7)
You set them both equal to 180 and solve for x so your answer will be 140
There are two lines from the center of the circle labeled 5.
The lines at 90 degrees from the 5 are chords. Because both lines are the same distance from the center they are the same length.
The one on the top is labeled as 9, so the line on the bottom is also 9 units long.
X is half the length, so would b 9 /2 = 4.5 units long.
Answer:
The probability of getting 2 socks of the same color is 1/3.
Step-by-step explanation:
In the drawer,
Number of blue socks = 4
Number of white socks = 8
Number of gray socks = 4
Total number of socks = 4 + 8 + 4 = 16
Total ways to select 2 socks form 16 socks is
Total ways to select 2 socks of the same color is
T = Possible ways of (2 blue + 2 white +2 gray) socks
= 
= 
= 
The probability of getting 2 socks of the same color is
Therefore, the probability of getting 2 socks of the same color is 1/3.
