Answer: 1/3

Step-by-step explanation: Since there are six sides to a number cube, the total number of outcomes will be 6.

Since there are 2 favorable outcomes, rolling a 1 or a 6,

the probability of rolling a 1 or a 6 is 2/6 which reduces to 1/3.

Answer:

1/3

Step-by-step explanation:

A cube by default has 6 sides, and a number cube generally is tallied from 1 - 6 (being the numbers are 1, 2, 3, 4, 5, 6).

You are solving for the probability of the numbers 1 or 6 being rolled, which are 2 numbers of the given amount. Change into a fraction form by placing part over the total amount of numbers:

2/6

Most likely, you will be told to simplify. Divide common factors from both the numerator & denominator:

(2/6)/(2/2) = 1/3

1/3 is the probability that a 1 or a 6 is rolled in a standard number cube.

John had a roll containing 24 2/3 feet of wrapping paper. He wants to divide it into 11 pieces. First, though, he must cut off 5

tatyana61 [14]

Given

John had a roll containing of wrapping paper

$=24\tfrac{2}{3}$

First, he must cut off 5/6 foot because it was torn.

He wants to divide it into 11 pieces.

To proof

As given in question

John had a roll containing of wrapping paper

$=24\tfrac{2}{3}$

$=\frac{74}{3}$ ( solving the mixed fraction form)

First, though, he must cut off 5/6 foot

than we get

$= \frac{74}{3} - \frac{5}{6}$

Taking the L.C.M of 3 and 6 is 6

$=\frac{148-5}{6}$

$=\frac{143}{6}$

=23.83 feet (approx)

He wants to divide it into 11 piece

length of the each piece

$=\frac{23.83}{11}$

length of the each pieces be 2.16 feet ( approx)

Hence proved

The triangle shown below has an area of 22 units.<br> Find the missing side.

emmasim [6.3K]

Answer:

Step-by-step explanation:

the formula for the area of a triangle is base times height divide by two. 22 is half of 44 so the base would have to be 11.

11 (base) times 4 (height) equals 44 divide by 2 equals final answer of 11

1/10, 3/20, 5/30, 7/40 arithmetic sequence geometric sequence neither

adell [148]

If a, b, c is an arithmetic sequence then a + c = 2b

a = 1/10; b = 3/20, c = 5/30

a + c = 1/10 + 5/30 = 3/30 + 5/30 = (3+5)/30 = 8/30
2b = 2 · 3/20 = 3/10 = 9/30

8/30 ≠ 9/30

If a, b, c is a geometric sequence then ac = b²

ac = 1/10 · 5/30 = 1/2 · 1/30 = 1/60
b² = (3/20)² = 9/400

1/60 ≠ 9/400

<span>Answer: Neither.</span>
