Answer:
He should sell it at the cost of 11,115.7895 Rs
Explanation:
Find original price:
100% - 5% = 95% = 9600
Let x be the original price.
Thus (95/100)x = 9600
x = (9600 x 100)/95
x = 960000/95
x = 10105.2632
Find the price in order to gain 10%.
x • 110% = 10105.2632 x 110/100 = 11,115.7895
Answer:
2
Step-by-step explanation:
well first do 17-9= (17-7)-2=10-2=8
so 8=6+_
subtract 6 from both sides and you get
2=_
so the blank is 2

Answer:
(1)
Step-by-step explanation:
Data given and notation
n=100 represent the random sample taken
estimated proportion with the survey
is the value that we want to test
represent the significance level
z would represent the statistic (variable of interest)
represent the p value (variable of interest)
Concepts and formulas to use
We need to conduct a hypothesis in order to test the claim that the true proportion is lower than 0.41.:
Null hypothesis:
Alternative hypothesis:
When we conduct a proportion test we need to use the z statistic, and the is given by:
(1)
The One-Sample Proportion Test is used to assess whether a population proportion is significantly different from a hypothesized value .
Calculate the statistic
Since we have all the info requires we can replace in formula (1) like this:
