Answer: 0.5467
Step-by-step explanation:
Let X be the random variable that represents the income (in dollars) of a randomly selected person.
Given : 
Sample size : n=350
z-score : 
To find the probability that the sample mean would differ from the true mean by less than 22 dollars, the interval will be
For x=15429
For x=15473
The required probability :-
Hence, the required probability is 0.5467.
Answer:
Yes.
Step-by-step explanation:
First, make a graph, or imagine one.
I'll be making an example graph that only goes up to 13 here.
Age - 10 11 12 13
Height
v
6ft
5ft
4ft
If we mark this graph with points, you will find that there is only 1 point on each age line!
Age - 10 11 12 13
Height
v
6ft *
5ft * *
4ft *
This means the answer is yes!
Answer:
Step-by-step explanation:
6x-9y=3
+x-9y=-22
first you take x-9y=-22 *-1 which will equal -x+9y=22
then you add
6x-9y=3
+-x+9y=22
----------------
5x=25
÷5 ÷5= x=5 then you plug 5 into each x spot
