You can cross multiply on this and then solve.
140 / 60 = 200 / x
140x = 12000
x= <span>85.7142857143
x= 85.7</span>
1:1, because there’s a same number of both !
We are given with
random samples = 300 batteries
defective samples = 9 batteries
level of significance = 0.1
Using the P-table values and using the given values, we see that the number of defective batteries are really less than 5%
Second option.
Functions are typically graphs that do not have a repeating y.
By going through each one of the given choices, you can deduce that only the second option has no repeated y values.
Hope this helps!
