1. ebony kept her bank account open for only 3 weeks, and the graph shows the entire 3 weeks. during that time, her greatest balance was $400.
(a) give the domain and range of the function.
(b) give an estimate to the nearest hundreds for . explain how you determined your estimate and tell what means in context of the situation.
(c) ebony’s bank balance first reached $0 on day 12. how would you show that information in function notation?
(d) ebony’s bank balance remained at $0 from day 12 through day 15. as you count segments from the left, which segment on the graph1, 2, 3, 4, 5, or 6 represents that information? explain how you know

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
