A college student is choosing between two data plans for her new cell phone. Both plans include an allowance
of 2 gigabytes of data per month. The monthly cost of
each option can be seen as a function and represented
with an equation:
• Option A: A(x) = 60
Option B: B(x) = 10x + 25
.
In each function, the input, , represents the gigabytes of
data used over the monthly allowance.
1. The student decides to find the values of A(1) and
B(1) and compare them. What are those values?

Plz help I don’t have much time before grades are due!

its not b

step-by-step explanation:

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;

there is no graph so i cant sorry
