Alright, let get started.
Kyle has a storage box having dimensions 2 ft long, 3 ft high and volume 12 cubic feet.
The formula for volume is =
Suppose the width is w so,
Dividing by 6 in both sides
w = 2 feet
Myla has a storage box that is 4 ft high and 2 feet long and volume 16 cubic feet.
Suppose the width is w hence
Dividing 8 in both sides
w = 2 feet
Hence the width of Kyle and Myla's boxes, both are 2 feet. : Answer
Hope it will help :)
OFFER A is cheaper.
Step-by-step explanation:
Given,
OFFER A
Pack of 5
£2.75
Pay for 3 packs get 1 free
And
OFFER A
Pack of 5
£2.75
Pay for 3 packs get 1 free
To find which offer is cheaper.
<u>For OFFER A</u>
For 4 Packets he needs to pay £2.75
He needs to buy 40 batteries.
He needs to buy 40÷(4×5) = 2 packets.
Total cost = £2.75 ×2 = £5.5
<u>For OFFER B</u>
For 4 Packets he needs to pay £2.52
He needs to buy 40 batteries.
He needs to buy 10 packets.
After discount he has to pay = £2.52
-(£2.52
×) = £1.68
Total cost = £1.68×10 = £16.8
Hence,
OFFER A is cheaper.
Answer: The mean number of checks written per day
Standard deviation
Variance
Step-by-step explanation:
Given : The total number of checks wrote by person in a year = 126
Assume that the year is not a leap year.
Then 1 year = 365 days
Let the random variable x represent the number of checks he wrote in one day.
Then , the mean number of checks wrote by person each days id=s given by :-
Since , the distribution is Poisson distribution , then the variance must equal to the mean value i.e.
Standard deviation :
