Serhud [2]

Answer:

3.75 cubic inches

Step-by-step explanation:

Volume = length x breadth x height

since the box holds 2 layers of 15 cubes

length contains 5 cubes= 5x1/2 inches=2.5 inches

breadth contains 3 cubes=3x1/2inches=1.5 inches

height contains 2 cubes=2x1/2inches=1.0 inches

Volume=2.5x1.5x1.0=3.75 cubic inches

2. An online bookstore sells both print books and e-books (books in an electronic format). Customers can pay with either a gift
Fudgin [204]

Answer:

a.0.12

b. Dependent

Step-by-step explanation:

a. The two events mentioned here are " print book is purchases" and "customer using gift card". P(P)=0.6 and P(C)=0.2. we have to calculate the probability of print book selection for purchase and payment is made through gift card i.e. P(P∩C). P(P∩C)=P(P)*P(C)=0.6*0.2=0.12.

b. If P(A∩B)=P(A)*P(B), then the two events are independent. Here in the given situation two independent variables are "purchase of e-book" and  "payment made using gift card"

P(E)=0.4

P(G)=0.2

P(E and G)=P(E∩G)=0.1

P(E)*P(G)=0.4*0.2=0.08 that is not equal to 0.1. So, the two events "e-book is purchased" and "Payment made by customer using gift card" are not independent.

Two tickets to the movies cost a total of $32. If a sales tax of 6% is added to the cost of the tickets, what is the FINAL PRICE
saul85 [17]

Answer: $33.92

Step-by-step explanation:

   We will find 106% of the tickets to answer this question.

   A percent divided by 100 becomes a decimal.

106% / 100 = 1.06

   We will multiply the price for the tickets by this decimal.

$32 * 1.06 = $33.92

     The final price for the tickets is $33.92.

What is the present age of Alex if he is one- fourth the age of a his father and if the age of the father is doubled, it is 20 y
AURORKA [14]

take father's age as x

if it is doubled i.e 2x .we get the answer as 20 less than 100 which means 100-20=80

accordingly the equation will be 2x=80

x=40

given that ,

son is 1/4 th of his father

hence ,

son = 1/4×(x)

I.e, 1/4×40 =10

Hope it helps
