Answer:
the percentage of these 120 guest purchase only day passes is 16.67%
Step-by-step explanation:
The computation of the percentage of these 120 guest purchase only day passes is shown below
= Number of guests purchased only day passes ÷ Given guest
= 20 ÷ 120 guest
= 16.67%
Hence, the percentage of these 120 guest purchase only day passes is 16.67%
We simply applied the above formula so that the correct value could come
And, the same is to be considere

Answer:
Yes, There is significant difference.
Step-by-step explanation:
Null Hypothesis , H0 : Mean income = 15000
Alternate Hypothesis , H1 : Mean income ≠ 15000
t = (x - u) / ( s / √n)
x = sample mean = 14500 here, u = population mean = 15000 here , s = standard deviation = 975 here , n = sample size
t = (14500 - 15000) / (975 / √169)
-500 / 75 = - 6.66
As calculated t value in absolute terms is > 1.96 , ie tabulated value at 95% significance level (two sided). So we reject the null hypothesis in favor of alternate hypothesis. Hence, we state that 'Mean Income ≠ 15000'
Answer:
0.2x+5>2
Step-by-step explanation:
0.2 is the same as 2/10;
(2/10)x>2-5
(2/10)x>-3
2x>-30
X>-15( since -15 is lesser than -14,-13,-12 and so on. the sign should be >
