Probabilities are used to determine the chances of events
The experimental probability of not spinning a 1 is 0.84
<h3>How to determine the probability of not spinning a 1</h3>
From the bar graph, we have the following highlights
- Total number of spin = 50
- Total spin of 1 = 8
So, the probability of spinning a 1 is:
![P(1) = \frac{8}{50}](https://tex.z-dn.net/?f=P%281%29%20%3D%20%5Cfrac%7B8%7D%7B50%7D)
![P(1) = 0.16](https://tex.z-dn.net/?f=P%281%29%20%3D%200.16)
The probability of not spinning a 1 is then calculated using the following complement rule
![P'(1) = 1 - P(1)](https://tex.z-dn.net/?f=P%27%281%29%20%3D%201%20-%20P%281%29)
![P'(1) = 1 -0.16](https://tex.z-dn.net/?f=P%27%281%29%20%3D%201%20-0.16)
![P'(1) = 0.84](https://tex.z-dn.net/?f=P%27%281%29%20%3D%200.84)
Hence, the experimental probability of not spinning a 1 is 0.84

Answer:
D) y = 4x + 2
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given ( 0, 2) ( -1 , -2 )
Given in equalities y = 4x + 2
put point (0,2) in equation y = 4x +2
2 = 4(0) +2
2 = 2
Therefore satisfies the point (0,2) equation y = 4x +2
put point (-1,-2) in equation y = 4x +2
-2 = 4(-1)+2
-2 = -2
Therefore satisfies the point (-1,-2) equation y = 4x +2
Answer:
P(paranthesis) E(exponents) M(multiplication) D(division) A(addition) S(subtraction)
Step-by-step explanation:
It is the order in how you solve an equation. If there is something with paranthesis around it then solve it first. Then exponents then multiplication ect.
The equations which are true for the values of x given are; x²-4 =0 and 4x²= 16.
<h3>Which equations are true for the values of x?</h3>
The values of x given according to the task content are; x = –2 and x = 2.
By considering equation; x²-4 =0
x² = 4
x = ±2
Also, by considering 4x²= 16;
x² = 16/4 = 4
x = ±4.
