What is f(5) if f(x) equals -2x + 1
Needed by Sunday
Pls include explanation

The answer is -9

Step-by-step explanation:

So all you have to do is just plug in 5 for x because x=5.

f(5)= -2x+1

f(5)= -2(5)+1

       -10+1

f(5)= -9

answer: a. 74

step-by-step explanation:

it shows divided evenly, so add the 37+37 = 74

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;
