Answer:
Interval within 1 standard deviation: (16.3,19.7)
Interval within 2 standard deviation: (14.6, 21.4)
Interval within 3 standard deviation: (12.9, 23.1)
Step-by-step explanation:
We are given the following in the question:
Population mean, 
= 18
Standard deviation, 
= 1.7
We have to find the following intervals:
Interval within 1 standard deviation:
Interval within 2 standard deviation:
Interval within 3 standard deviation:
Answer:
The normal undiscounted price of the book is $17.25.
Step-by-step explanation:
This question can be solved using a rule of three.
After a 35% discount, a book costs $11.21
This means that $11.21 is 100-35 = 65% = 0.65 of the original price x.
How much is x, which is 100% = 1?
$11.21 - 0.65
$x - 1
The normal undiscounted price of the book is $17.25.
Answer:
a) 1200
b) 150
Step-by-step explanation:
a) total revenue = target amount + expenses
... total revenue = 1000 + 200
... total revenue = 1200
b) total revenue = adult tickets × adult ticket price
... 1200 = adult tickets × 8 . . . . . . . . . . fill in the information you know
... 1200/8 = adult tickets = 150 . . . . . divide by 8
Is there any more context to this question? Or can you use and answer. There are a lot of answers to this question, so long as x is not finite
Answer:
357
Step-by-step explanation:
hello :
note : the n th term of an arithmetic sequence is :
An =A1+(n-1)d ....a common difference is : d and A1 the first term
in this exercice : d = -3-(-7) =-7-(-11) = 4 A1 = -11
when : n =93 you have the 93rd term A93
so : A93 = -11 +(93-1)(4)
A93 = 357
