Answer:
B) 275n + 1000 = 2700
Step-by-step explanation:
n is just a placer holder for how many days the Carter family can vacate.
That being said, the question says that they will spend 275 per day, which is per n. You want to multiply 275 by n.
Then the question says it plans to spend $1000 on meals (that's a lot). Instead of substracting, you are going to add for this equation. You want the equation to match; you want both sides to equal 2700 so you can determine how many days you can spend there.
Answer:
94
Step-by-step explanation:
Margin of error = E = $ 120
Confidence Level = 95%
The z-score for 95% confidence level from the z-table = z = 1.96
Population standard deviation = σ = $593
Sample size = n = ?
The formula to calculate the margin of error is:
Re-arranging the equation, we get:
Using the given values in above equation, we get:
Rounding of to next higher integer, we get n = 94
Thus, we need a sample size of 94 to estimate an unknown population mean μ
I think it is 45.5. 1/2 base*height. (9*9 = 81. 81/2 = 45.5.
it is 24.745, according to this calculator
Lots of numbers
if you mean counting numbers then then numbers are
2 and 43
if you include decimals then there are very many
