A grocery supplier believes that in a dozen eggs, the mean number of broken eggs is 0.6 eggs with a standard deviation of 0.3 eggs. You buy 3 dozen eggs without checking them. A) what is the expected number of broken eggs?B) what is the standard deviation?

(a) 1.8 eggs

(b) 0.52 eggs

Step-by-step explanation:

According to the problem, computation of the given data are as follows:

The mean number of broken eggs in a dozen E(X) = 0.6

Standard deviation SD(X) = 0.3

(a). For 3 dozen eggs, number of broken eggs can be calculated by using following formula,

E(X) for 3 dozen = 3 × 0.6

= 1.8 eggs

(b). Standard deviation for 3 dozen can be calculated as follows,

SD (X) = ×

=

= 0.52 eggs

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
