We are given the different rates and charges and is asked in the problem the unknown tax rate she pays on meals if the total cost of the trip is equal ot $420.04. In this case, the equation goes:
80 x 3 + 80 x 0.1 x 3 + 80 x 0.09 x 3 + 109.3 x 1.15 + 109. 3 x z = 420.04
z = 0.08
Answer:
49 million impressions
Explanation:
In media gross impressions are defined as the total number of people that represented in a media schedule. When a media campaign is launched unique impressions are counted to make up gross impression.
For example on digital marketing a visit from a customer is counted as one impression by cookies. Once a new user logs in a new impression is created.
In this instance for the television program total number of impressions for one advert can be calculated as
Impression = Average persons * Number of spots (commercials)
Impression= 4 million persons * 10
Impression = 40 million
For the magazine it aims to target 3 million people with 3 full page adverts
Impression = 3million * 3
Impression = 9 million
Therefore total impression of the campaign
Gross impression= 40 million + 9 million
Gross impression= 49 million
Answer:
t value is 1.495
Explanation:
The null and alternative hypothesis are :
H0 : mu = 1327
ha: mu > 1327
This is a one tailed test
Critical value = 1.771
at 0.05 significance level with df = 14-1 = 13
test statistics:
s = 411.53, n = 14
t = (xbar -mu)/(s/sqrt9n))
= ( 1491.43 - 1327)/(411.53/sqrt(14))
= 1.495
Decision:
Reject H0 if tstat > 1.771
Fail to reject H0
