Answer:
Step-by-step explanation:
Sidney Crosby, Pittsburgh Penguins
Let, the number = x
Then, 2x + 3 = 4x - 5
2x - 4x = -5 - 3
-2x = -8
x = 8/2
x = 4
In short, the number would be: 4
Hope this helps!
Answer:
The z-score corresponding to an observed value of x of 2 is 0.215.
Step-by-step explanation:
We are given that a variable x has the possible observations shown below;
Possible observations of X: -3, -1, 0, 1, 1, 2, 4, 4, 5.
Firstly, we will find the mean and the standard deviation of X, i.e;
Mean of X, () =
=
= = 1.44
Standard deviation of X, () =
=
= 2.603
Now, the z-score corresponding to an observed value of x of 2 is given by;
z-score =
= = <u>0.215.</u>

Step-by-step explanation:
Answer:
(-3 , 0) (0, 2) (6, -6)
Step-by-step explanation:
Solving for x - intercept:
2x - 3(0) = -6
2x = -6
2x/2 = -6/2
x = -3
One point would be (-3 , 0) .
Solving for y-intercept:
2(0) - 3y = -6
-3y = -6
-3y/-3 = -6/-3
y = 2
Another point would be (0, 2).
When 'x' equals 6:
2(6) - 3y = -6
12 - 3y = -6
12 - 12 - 3y = -6 - 12
-3y = -18
-3y/3 = -18/3
y = -6
The third point would be (6, -6).
