2x−5=19

Step-by-step explanation:  Add 55 to both sides.

                                              2x=19+5

                                             Simplify  19+519+5  to  2424.

                                             2x=24

                                             Divide both sides by 22

                                             x= 24/2

                                           Simplify 24/2 to 12

                                        x=12

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;

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
