Percent means parts out of 100, remember that
12% off
12% off means 100%-12%=88%
find 88% of that
then take 3% and addd that
3% off of 100=100+3=103% of that
then
so original price=p
find 88% of that then 103% of that
p*0.88*1.03=final cost
p*0.9064=final cost
0.9064p=final cost
Answer: v=w-y

Answer:
Step-by-step explanation:
For the null hypothesis,
µ = 60
For the alternative hypothesis,
h1: µ < 60
This is a left tailed test
Since the population standard deviation is not given, the distribution is a student's t.
Since n = 100,
Degrees of freedom, df = n - 1 = 100 - 1 = 99
t = (x - µ)/(s/√n)
Where
x = sample mean = 52
µ = population mean = 60
s = samples standard deviation = 22
t = (52 - 60)/(22/√100) = - 3.64
We would determine the p value using the t test calculator. It becomes
p = 0.00023
We would reject the null hypothesis if α = 0.05 > 0.00023
The answer is 8shares
