Answer: a) 278382 oz
b) 43 oz
c) 64.1 oz
Step-by-step explanation:
a) 8 T. 1,398 lb. 14 oz. × 6
First we need to change it in 'oz'.
As we know that

so, it becomes,

8 T. 1,398 lb. 14 oz. × 6 becomes

b) 349 lb. 6 oz. ÷ 130
It becomes,

c) 6 T. 294 lb. ÷ 3,071
First it becomes,

At last it becomes,

Hence, a) 278382 oz
b) 43 oz
c) 64.1 oz

Step-by-step explanation:
Given that the IQs of university​ A's students can be described by a normal model with mean 140 and standard deviation 8 points. Also suppose that IQs of students from university B can be described by a normal model with mean 120 and standard deviation 11. Let x be the score by A students and Y the score of B.
A)
B) Since X and Y are independent we have
X-Y is Normal with mean = 140-120 =20 and 

C) For a group of 3, average has std deviation = 

Answer:
c=rt is the equation to express the total cost c to use the internet at the coffeehouse for t hours.
Step-by-step explanation:
Given A coffeehouse charges a flat rate, r for each hour customer wants to use the internet. we have to write the equation to express the total cost c to use the internet at the coffeehouse for t hours.
Charges of internet per hour = r
Total hour = t hours
Hence, Cost = (Charges per hour)(Total hours)
=
∴ c=rt
which is the linear equation to express the total cost c to use the internet at the coffeehouse for t hours.
