Y - y1 = m( x - x1); where m = (y2 - y1)/(x2 - x1);
We have m = (6-0)/(7-5) = 6 / 2 = 3 ;
The equation of the line is: y - 0 = 3(x-5);
Finally: y = 3x - 15.
Use the z-score:
112 - 100
For 112, the z-score is --------------- = 12/15, or 0.8.
15
Next, find the AREA under the standard normal curve TO THE LEFT OF 0.8.
Use either a z-score table or a calculator for this purpose.
Using my calculator, I found that this area is 0.532. That places 112 in the 53rd percentile.
82 would be in a lower percentile: the 12th percentile.
Let me know if you have questions about how to use a calculator to do these calculations.
The second option - 3/25.
The probability of the first one is 3 blue socks over 10 socks in total = 3/10
The probability of the second one is 4 red socks over 10 socks in total = 4/10
Multiply the two probabilities to get the probability of having the first sock as blue and the second sock as red.
3/10 * 4/10 = 3/25
Answer:
65%
Step-by-step explanation:
You can use the equation " is over of " to solve this. 247/380 * ?/100. After simplifying, you get 24700/380 which equals 65%.
Brainliest would be appreaciated! :-)
