Answer:
Pvalue = 0.063008
Step-by-step explanation:
Given :
Sample size, n = 63
The test statistic = - 1.53
To test if average room price is significantly different from $110 ; μ = $110
H0 : μ = 110
H1 : μ < 110
From the test statistic value obtained, we could see that the test is left tailed
The Pvalue :
P(Z < - 1.53) = 0.063008
If the claim is to be tested at 5% level of confidence then
Pvalue > 0.05 ; Hence, we fail to reject the. NULL. Hence, average price is not significantly different from $110
Answer:
the best value is two 50 ml bottles
Step-by-step explanation:
Okay focus with me , if you buy a bottle of 50 ml you will get a second for half price so we can say that --> 2 bottles of 50 ml =

We get 100 ml with £67.5 just , but when you buy 80ml you must pay £55 Hum !
then you can dived the volume of bottle with price ...
- the price of one ml is 0.675 in first State

- in the second state the price of one ml is

then :

so the best value is two 50 ml bottles
Answer:
1,5 and -7,5
Step-by-step explanation:
Answer:
1. 19.
2. -7.
Step-by-step explanation:
1. Put x = 2 then simplify:
f(x) = 2(3^x) + 1
f(2) = 2(3^2) + 1
= 2*9 + 1
= 18 + 1
= 19.
2. f(-3) = 4(-3) + 5
= -12 + 5
= -7.
This is how you would set it up
42 47
----- -----
100 x
Then, cross multiply. You should get this:
42x = 4700
Then, solve that problem
42x = 4700
----- -------
42 42
x = 111 < (the answer turns out as a decimal but you should take the whole number)
Then subtract 111 and 100
111 - 100 = 11
Answer - 11%
Hope this helps!
