Answer:
#1: inequality form: x ≤ –1 or x ≥ 2
interval notion: ( -∞,-1] U [2,∞)
#2: false/no solution
#3: A) point form: (3,9)(-1,1)
equation form: x= 3,y=9 and x= -1,y=1
B)point form: (1,7)(7,1)
equation form: x=1,y=7 and x=7,y=1
Step-by-step explanation:
#1: solve for x by simplifying both sides of the inequality, then isolating the variable.
#2: N/A
#3: solve for the first variable in one of the equations, then substitute the results into the other question.
Perimeter of a rectangle is given by (2 × Length(l)) + (2 × Width(w)) = 2l + 2w
l= 11 feet
2(11) + 2w = 46
2w = 46 - 22 = 24
w = 24/2 = 12 feet
Width = 12 feet.
Answer:
Binomial
There is a 34.87% probability that you will encounter neither of the defective copies among the 10 you examine.
Step-by-step explanation:
For each copy of the document, there are only two possible outcomes. Either it is defective, or it is not. This means that we can solve this problem using the binomial probability distribution.
Binomial probability distribution:
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinatios of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem
Of the 20 copies, 2 are defective, so .
What is the probability that you will encounter neither of the defective copies among the 10 you examine?
This is P(X = 0) when .
There is a 34.87% probability that you will encounter neither of the defective copies among the 10 you examine.
Answer:
La respuesta es solo dividir
