Answer:
$ 2600 on Friday's game and $ 1456 on saturday's game.
Step-by-step explanation:
Let x be the money ( in dollars) earned on friday and y be the money ( in dollars ) earned on Saturday,
Since, total earning on friday and saturday is $ 4056.00,
⇒ x + y = 4056 -----(1),
Also, Friday's game generates $1144.00 less than Saturday's game.
⇒ y - x = 1144 -------(2),
Equation (1) + equation (2),
2y = 5200,
y = 2600
From equation (1),
x + 2600 = 4056
x = 1456
Hence, $ 2600 was taken on Friday's game and $ 1456 was taken on saturday's game.
Answer:7881 years
Step-by-step explanation:
You can use the equation
fraction remaining = 0.5n where n is # of half lives elapsed
n = ?
fraction remaining = 1 - 0.612 = 0.388
0.388 = 0.5n
n = 1.37 = the # of half lives
1.37 x 5750 yrs = 7881 years

Answer: $1,842
Step-by-step explanation:
John wants to earn 25% of his investment of $50,000 which is:
= 25% * 50,000
= $12,500
He has expenses of $9,600 yearly so the rent he should charge per year in order to make his 25% requirement as income is:
= Expenses + Return
= 9,600 + 12,500
= $22,100
Rent per month is:
= 22,100 / 12
= $1,842
Answer:
The customer can conclude that the company's claim is correct
Step-by-step explanation:
The percentage of lids that has a free yogurt coupon = 20%
The number of cups a loyal customer purchases = 85 yogurt cups
The number of cups that contained a coupon = 12 (14.1%)
The confidence interval performed = 99% confidence interval for the proportion of yogurt cups containing coupon codes
The interval obtained = (0.044, 0.238)
Therefore, the range of proportion within which the true proportion exists is 0.044 < 
< 0.238
The range of percentage within which the true percentage exist is therefore;
0.044 × 100 = 4.4% < × 100 < 0.238 × 100 = 23.8%
Given that the possible true percentage of lids that has a coupon is between 4.4% and 23.8% at 99% confidence level, the customer can conclude that only 12 of his yogurt cup contained coupon by chance and that the company's claim is correct.
