In a souvenir shop, jodi purchased 2 small picture frames and 1 large one for $28. mike bought 3 medium-size frames and 2 large ones for $56. shelly bought a small, a medium, and a large frame for $30. write and solve a system of equations to find the price of each size of picture frame.

a. small: 8
medium: 10
large: 12

b. small: 5
medium: 10
large: 15

c. small: 6
medium: 8
large: 16

d. small: 10

The weights of broilers (commercially raised chickens) are approximately normally distributed with mean 1387 grams and standard deviation 161 grams. what is the probability that a randomly selected broiler weighs more than 1,425 grams?

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 + 4x + 5 = 0

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 25002500 grams and a standard deviation of 800800 grams while babies born after a gestation period of 40 weeks have a mean weight of 27002700 grams and a standard deviation of 385385 grams. if a 3232-week gestation period baby weighs 21252125 grams and a 4040-week gestation period baby weighs 23252325 grams, find the corresponding z-scores. which baby weighs lessless relative to the gestation period?
