A pair of dice are rolled. What is the probability of rolling 6 or less?
Allushta [10]

Answer:

1/36

Step-by-step explanation:

The probability of rolling a number less than 6 or 6 itself on one die is 1/6. A pair of dice would be the combined probability 1/6*1/6 which is 1/36. So there's a 1/36 chance of having both dice roll numbers less than 6 or 6 itself.

Some angles are shown. Complete each of the 2 activities for this Task. Activity 1 of 2 The measure of angle NOP is 140°. Which
garik1379 [7]

Answer:

A. 23+x=140

Step-by-step explanation:

The angle addition postulate states that the measure of a larger angle formed by two or more smaller angles placed side by side is the the sum of the smaller angles. The angle addition postulate states that if B is in the interior of AOC , then:

m∠AOB + m∠BOC = m∠AOC.

From the image:

∠NOP = ∠NOQ + ∠QOP

∠NOP = 140, ∠NOQ = x, ∠QOP = 23

substituting:

140 = x + 23

x = 140 - 23 = 117

∠NOQ = 117°

Can someone please help me
Natalija [7]
ANSWER: $84

EXPLANATION:

We need to know the surface area of the room with the specified dimensions.

A = 2(wl + hl + hw)

w = 12
h = 8
l = 16

A = 2( (12 * 16) + (8 * 16) + (12 * 8) )

A = 2(192 + 128 + 96)

A = 2(416)

A = 832 square feet


832 / 150 = 5.546666666666667

(Round that up to the next whole number)
