Answer:

\frac{6}{49}

Step-by-step explanation:

GIVEN: There are two boxes. in the first box there are 7 cards numbered from 1 to 7 the second box also contains 7 cards from 1-7 pick one card from each box.

TO FIND: probability that the sum of the two two cards is at least 12.

SOLUTION:

sample case such that sum of cards is 12 : (5,7),(7,5),(6,6)

sample case such that sum of cards is 13 : (7,6),(6,7)

sample case such that sum of cards is 14 : (7,7)

Total sample case such that sum is atleast 12 =6

Total sample cases=49

probability that the sum of the two two cards is at least 12=\frac{\text{sample case in which sum is atleast 12}}{\text{total sample cases}}

=\frac{6}{49}

probability that the sum of the two two cards is at least 12 is \frac{6}{49}

1.A cube has side lengths of 15 inches, what is the surface area and volume of the cube? 2. A cube has side lengths of 8 inches,
omeli [17]

Answer:

Cube 1: 3375 cubed inches, 1350 inches squared.

Cube 2: 512 cubed inches, 384 inches squared.

Step-by-step explanation:

Formula for Volume of a Cube:  V=s^3\\ (s - side length)

Formula for Surface Area of a Cube: SA=6s^2 (s- side length)

<h3>For Cube 1:</h3>

The side length's 15 inches.

Find the volume:

V=15^3\\\rightarrow 15*15*15=3375\\\boxed {V=3375}

The volume of cube one is 3375in³.

Find the surface area:

SA=6(15)^2\\\rightarrow 15^2 = 225\\SA = 6 * 225\\\boxed {SA=1350}

The surface area of cube 1 is 1350in².

<h3>For Cube 2:</h3>

The side length's 8 inches.

Find the volume:

V=8^3\\\rightarrow 8*8*8= 512\\\boxed {V=512}

The volume of cube two is 512in³.

Find the surface area:

SA=6(8)^2\\\rightarrow 8^2=64\\SA=6*64\\\boxed {SA=384}

The surface area of cube 2 is 384in².
