Note: The values in the table are not correct because the sum of the probability of all events is not equal to one. The should be 0.13 and 0.33 instead of 0.113 and 0.133 respectively.
Given:
The probability distribution for a random variable x is given in the table.
x : -5 -3 -2 0 2 3
P(x) : 0.17 0.13 0.33 0.16 0.11 0.10
To find:
The probability of -2.
Solution:
From the given probability distribution for a random variable x, it is clear that the value of the probability is 0.33 corresponding to -2.
![P(-2)=0.33](https://tex.z-dn.net/?f=P%28-2%29%3D0.33)
Therefore, the probability of -2 is 0.33.
The y-intercept is 4.
The line crosses (“intercepts”) the y-axis when x = 0. If x = 0 in the equation, then y = 4.
Answer:
cos2q
Step-by-step explanation:
sin2q x cos2q/sin2q
= cos2q
On average, the number of goals that a player will score for every additional hour of practice based on the regression is 4/5.
<h3>How to calculate the value?</h3>
It should bm be noted that based on the information given, the slope will be:
(y2 - y1)/(x2 - x1)
= (6 - 2)/(6.5 - 1.5)
= 4/5
Therefore, the number of goals that a player will score for every additional hour of practice is 4/ of a goal.

Answer:
Step 1
Because the number in front of the bracket is 1 and it is also affected by the negative sign(-),5 is supposed to be negative not positive because (negative by positive is negative)
And since the first step has an error in it,the remaining steps would also be wrong.
