Answer:
X= -3
Step-by-step explanation:
-3^3 can also be written as -3*-3*-3, which is -27
Answer:
Probability that both of them use it = 0.3945
Step-by-step explanation:
Given:
Student use app = 63%
Number of chosen student = 2
Computation:
Assume total number of student = 100%
So, probability that both of them use it.
⁶³C₂ / ¹⁰⁰C₂

Therefore, probability that both of them use it = 0.3945
Answer:
See picture below
Step-by-step explanation:
To graph properly, remember that:
- The y intercept of the function, is the value of the function when x=0, and tells (in this case y=1 is the intercept). Locate this point in the graph.
- The x intercept, which is the value of x when y=0 is x=1. Locate it in the graph.
- You now have two points of a straight line: join this two points and you would have done it!
Answer:
x = - 
Step-by-step explanation:
A theorem states that (using letters from in this problem) that:
AB * BE = DC * CE
Applying that you can find that:
11 ( x + 1 ) = 1 ( x + 4 )
11 x + 11 = x + 4
11 x + 11 - x = x + 4 - x
10 x + 11 = 4
10 x + 11 - 11 = 4 - 11
10 x = -7
10 x / 10 = -7 / 10
x = -
