Answer:
y = -3m + 7
Step-by-step explanation:
Given the two point:
- A (2, 1)
- B (5, -8)
We use Slope-Intercept Form to create the equation of the line that goes through the two points above
y =mx + b where m is the slope and b is the y-intercept
Step 1: find the slope of it
<=> m =
=> our equation: y = -3x + b (1)
Now, plug one of the points (either one!) together with m into (1), we have:
1 = -3*2+ b
<=> b = 7
Hence, the equation is: y = -3m + 7
Hope it will find you well.
Answer:
The distance of UFO from KA-1212 is 1229.7 km.
Step-by-step explanation:
We are given that,
Distance between the satellites = 900 km
Angle made by the satellite KA-1212 = 60°
Angle made by the satellite SAL-11 = 75°
So, from the figure below,
The third angle is given by = 180° - (60°+75°) = 180° - 135° = 45°
Then, using the law of sines, we have,
The theoretical probability =, The experimental probability =
<h3>What is experimental probability?</h3>
The experimental probability of an event occurring is the number of times that it occurred when the experiment was conducted as a fraction of the total number of times the experiment was conducted.
The sample will be ={1,2,3,4,5,6,7,8,9}=9
favourable outcomes={1,3,5,7,9,}=5
The theoretical probability of spinning and odd number =
As she spends the spinner 12 times
The experimental probability =
Hence the theoretical probability =, The experimental probability =
