F(2) if f(x) = 2x - 5

The answer is 4.

Step-by-step explanation:

f(2) = -1

Step-by-step explanation:

Plug in 2 for x in the equation: f(2) = 2(2) - 5

Remember order of operations/ PEMDAS

f(2) = 4-5                  

f(2) = -1

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;

you could deduce the conclusion directly using the facts pertaining to the specific situation.
