Answer:
A∪B = { The Real numbers }
Step-by-step explanation:
Given:
Let A = {the Rationals} and B = {the Irrationals}.
Find
A∪B.
Solution :
AUB means collection all the element of A and all the element of B.
element of A = Rational number and
element of B = Irrational number
Real number : All the including rational and irrational numbers are called as real number.
∴ A∪B = { The Real numbers }
Answer:I think it’s 12/7
Step-by-step explanation: I think it is
Answer:
a. P=0.01222
b. P=0.98778
c. The probability of rejecting the claim is now P=0.00298.
Step-by-step explanation:
In this case, we evaluate the sampling distribution for a population proportion π=0.8 with a sample size of 25.
We need to calculate the probability of getting a sample mean below 15, which means p=15/25=0.6.
The standard deviation of the sampling distribution is:
The z value por p=0.6 is
The probability of having a sample mean less than 15 is
The probaiblity of not rejecting the claim is 1-0.01222=0.98778
If the value 15 is replaced by 14, we have a new value of p=14/25=0.56.
There will be less chances of rejecting the hypothesis.
Line 1 ——> y= 3/2x +1/2
Line 2 ——> y= -2/3x+4/3
Line 3 ——> y= -2/3x-7
therefore,
Line 1 & Line 2 : Perpendicular
Line 1 & Line 3 : Perpendicular
Line 2 & Line 3 : Parallel
hope this helped :)
