Answer:
M=2,179.29
The average exceeds the estimate
Her expenses would need to be $1,625.00
Step-by-step explanation:
1.) What is the mean of her friends' personal expenses?
The mean is defined as the average expense value, calculated as follows:
2.) Is the average higher or lower than the estimate?
Given the estimate of $2,110, the average is indeed higher than this estimate.
3.)What amount of personal expenses would Ashley need to maintain a combined average of $2,110 with her friends' amounts for that school year?
Her needed amount of expenses would be $1,625.00.
Response:
The goat population will reach 1000 in a time span of 12.4 years
Detailed explanation:
After t years, the population of goats is described by
where 
indicates the initial count of goats and b is the growth rate per capita.
Based on the problem,
- b = 0.5
- N = 1000
Answer:
160/1001, 175/1001
Step-by-step explanation:
i) We calculate:
₈C₁ methods to select 1 new camera from a selection of 8
₆C₃ methods to select 3 refurbished cameras from a selection of 8
₁₄C₄ methods to select 4 cameras from the total of 14 cameras
The probability formula is:
P = ₈C₁ ₆C₃ / ₁₄C₄
P = 8×20 / 1001
P = 160 / 1001
P ≈ 0.160
ii) For at most one new camera, it means we want either one new camera or none at all. We've calculated the probability of selecting one new camera already. The probability of not selecting any new camera is equivalent to selecting 4 refurbished cameras:
P = ₆C₄ / ₁₄C₄
P = 15 / 1001
Therefore, the combined probability is:
P = 160/1001 + 15/1001
P = 175/1001
P ≈ 0.175
Answer:
2550
Step-by-step explanation:
1) The initial amount borrowed is 17,000.
2) The interest rate is set at 5%.
3) Therefore, to calculate interest: 0.05 * 17000 equals 850.
4) Since the repayment takes 3 years, multiply by 3: 850 * 3 equals 2550.
5) Thus, the total interest that the shoe store is obligated to pay is 2550.
