Answer:
Number of cookie boxes will fit into the large box = 40
Step-by-step explanation:
Length breadth and height are given in order.
Size of large box = 10 in x 10 in x 12 in
Size of small box = 2 in x 5 in x 3 in
Complete volume of large box can be utilized since length breadth and height of large box is multiple of small box.
Volume of large box = 10 x 10 x 12 = 1200 in³
Volume of small box = 2 x 5 x 3 = 30 in³
Number of cookie boxes will fit into the large box
Number of cookie boxes will fit into the large box = 40

Answer:
In order to calculate the expected value we can use the following formula:
And if we use the values obtained we got:
Step-by-step explanation:
Let X the random variable that represent the number of admisions at the universit, and we have this probability distribution given:
X 1060 1400 1620
P(X) 0.5 0.1 0.4
In statistics and probability analysis, the expected value "is calculated by multiplying each of the possible outcomes by the likelihood each outcome will occur and then summing all of those values".
The variance of a random variable Var(X) is the expected value of the squared deviation from the mean of X, E(X).
And the standard deviation of a random variable X is just the square root of the variance.
In order to calculate the expected value we can use the following formula:
And if we use the values obtained we got:
