Kayla rolls two numbers cubes numbered 1 to 6. What is the probability that the sum of the numbers rolled will be 5

1 answer:

6 0

There are 2 cubes and each cube has 6 sides. There is a 1/6 chance of rolling a 5 for ONE cube (since each side is a different number ranging from 1 to 6). But, since we have to cubes, it would be 1/3. This is because your chance to roll a five is doubled due to 2 cubes.

Answer:

Step-by-step explanation:

For the given intervals

( - ∞, - 5) ← use any value < - 5 but not - 5, the parenthesis ) indicates that x is less than - 5 but not equal to - 5

(- 5, - 1) ← - 4, - 3, - 2 can be used but not - 5 or - 1

(- 1, 4) ← 0, 1, 2, 3 can be used but not - 1 or 4

(4, ∞ ) ← use any value > 4 but not 4

Hence

3 can be used in (- 1, 4)

- 6 can be used in (- ∞, - 5)

zero can be used in (- 1, 4)

- 5 cannot be used in any of the given intervals

The resistance of a wire varies directly with its length and inversely with the square of its diameter. If 100 feet of wire with

DaniilM [7]

Answer:

14 ohms

Step-by-step explanation:

The resistance varies directly with length, so increasing the length by a factor will increase the resistance by the same factor.

The length of the wire increased by a factor of 1.4 from 100 ft to 140 ft. That means the resistance will increase by a factor of 1.4 from 10 ohms to 14 ohms. (The diameter did not change.)

The longer wire will have a resistance of 14 ohms.
