Write the equation in standard form. Then factor the left side of the equation.

2x2 + 7x = 15 (question)

(Answers)
(2x – 5)(x + 3) = 0

(2x + 5)(x – 3) = 0

(2x + 3)(x + 5) = 0

(2x – 3)(x + 5) = 0

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;

not sure but it may be b, as i said i'm not sure.
