Will give brainliest to best answer- due today use the quadratic formula to solve x^2-4x+3, show your work. then describe the solution.

Firstly, using our equation plug in the values into our equation (a = 1, b = -4, and c = 3):

Next, solve the exponent and multiplications:

Next, solve the subtraction:

Next, solve the square root:

Next, you are going to solve this equation twice - once with the  + symbol, once with the - symbol as such:

Your zeros (x-intercepts) are 3 and 1. These solutions are real and rational.

step-by-step explanation:

just for that im not answering

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;
