Alicia has invented a new app that two companies are interested in purchasing for a 2-year contract. Company \text{A}Astart text, A, end text is offering \$10{,}000$10,000dollar sign, 10, comma, 000 for the first month and will increase the amount each following month by \$5000$5000dollar sign, 5000.
Company \text{B}Bstart text, B, end text is offering \$500$500dollar sign, 500 for the first month and will double their payment each following month.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

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;

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
