Marian horneó 111 galletas para vender. De las cuales 2/3 les puse glaseado y a las restantes chocolate. Cada galleta de chocolate la vendió en $4.50 y las de glaseado en $2 más que las de chocolate. ¿Cuánto obtendrá de ganancia si vende todas las galletas?

$647.50

Step-by-step explanation:

111 x 2/3 = 74

111 x 1/3 = 37

$4.50 x 37 = $166.50

$6.50 x 74 = $481

$481 + $166.50 =

$647.50

¡Espero que ayude!

37 chocolate $166.5

74 glaseado $481

481 + 166,5 =

$647.5

Step-by-step explanation:

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;
