The answer for this question is 36
Answer:
a. 
b. 
Step-by-step explanation:
Theoretical probability is what we expect to happen and experimental probability is what actually happens.
a. In theoretical probability, it doesn't matter what happened in the past. So basically we want to know the probability of rolling a 3 when a number cube is rolled.
There are 6 faces (from 1 to 6) in a number cube. And there is 1 "3". So the probabilty of rolling a 3 is:
1/6
b. In experimental probability, we need to know what happened before. When the cube was rolled 450 times, it came up "3", 67 times.
Hence the experimental probabilty of rolling a "3" is:
67/450
Answer: 5x² + 13x - 6 = 0
Step-by-step explanation:
Represent the roots with X i.e.
X = -3 ; X = 2/5
Moving the values of X over the equator we have;
X + 3 = 0 ; 5X - 2 = 0
Equating both equations to zero we can obtain;
(X + 3)(5X - 2) = 0
Opening the brackets we get;
5x² - 2x + 15x - 6 = 0
The result of the above equation gives;
5x² + 13x - 6 = 0
Answer:
0.485 lb
6.83 lb - 3.57 lb = 3.26 lb
3.26 lb - 0.35 lb = 2.91 lb
2.91 lb / 6 = 0.485 lb
Answer:
(s-t)(-1) = -1
(s+t)(-1) = -7
Step-by-step explanation:
Given the following set of functions
s(x)=2x-2
t(x)=3x
(s-t)(x) = s(t) - t(x)
(s-t)(x) = 2x - 2 - 3x
(s-t)(x) = -x -2
(s-t)(-1) = -(-1) - 2
(s-t)(-1) = 1-2
(s-t)(-1) = -1
(s+t)(x) = s(t) + t(x)
(s+t)(x) = 2x - 2 + 3x
(s+t)(x) = 5x -2
(s+t)(-1) = 5(-1) - 2
(s+t)(-1) = -5-2
(s+t)(-1) = -7
