Answer:

1/8

Step-by-step explanation:

When three fair coins are tossed there is a chance of occuring eight combinations. Hence the probability is 1/8. Each outcome of each flip of a fair coin has a probability of 0.5.

Answer:

1/8

Step-by-step explanation:

each outcome of a flip is half and half, knowing that a coin has two sides-heads and tails, so to head three heads in a row multiply 0.5 by itself 3 times, to get 1/8:

1/2 * 1/2 * 1/2=1/8,

Write an absolute value inequality that describes the acceptable weights, w, of a 20-ounce bottle of sports drink.
Shtirlitz [24]

Answer: 0\leq w\leq 20

Step-by-step explanation:

Since, Here w represents the weight of the bottle.

And, According to the question, he acceptable weights, w, of a 20-ounce bottle of sports drink.

That is, weight of the bottle can not be higher than 20 or the it can be atleast 20.

Therefore,  w\leq 20

And, the weight can not be negative.

Therefore, 0\leq w

Thus, the required inequality is,

 0\leq w\leq 20

The area of a rectangular wall of a barn is 64 square feet. Its length is 8 feet longer than twice its width. Find the length an
ValentinkaMS [17]
L×w=64 ft^2...(1)
2w+8= l...(2)

l=64-w...(1a)

2w+8= 64-w
2w+w+8=64
3w=64-8
3w÷3= 56÷3
w=18.6'

l×w= 64
l×18.6= 64
l= 64÷18.6
l= 3.44 to the nearest hundredths.

Geo please help I have two question!

Answer:

Step-by-step explanation:

From the given right angle triangle,

the hypotenuse of the right angle triangle is 13

With m∠65° as the reference angle,

y represents the adjacent side of the right angle triangle.

x represents the opposite side of the right angle triangle.

To determine the value of x, we would apply the sine trigonometric ratio which is expressed as

Sin θ = opposite side/hypotenuse. Therefore,

Sin 65 = x/13

x = 13Sin65 = 13 × 0.906

x = 11.8 to the nearest tenth
