Answer:

1/8

Step-by-step explanation:

The probability of getting tails on a single flip is 1/2.

Each of the flips is an independent event so you must multiply the probability of getting tails on each flip together.

So, your answer will look like this

[tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] ; which equals;

1/8

Answer:

1/8

Step-by-step explanation:

To calculate the probability you have to name all possible results first. If you mark a result of a single coin flip as  H  for heads or  T  for tails all results of  3  flips can be written as:

Ω = { ( H , H , H ) , ( H , H , T ) , ( H , T , H) , ( H , T , T ) , ( T , H , H ) , ( T , H , T ) , ( T ,T , H ) , ( T , T , T ) }

Each triplet contains results on  1st,  2 nd and  3 rd coin. So you can see that in total there are  8  elementary events in  Ω.

| Ω |  =  8

Now we have to define event  A  of getting tails three times.

The only elementary event which satisfies this condition is  ( T , T , T )  so we can write that:

A  =  { ( T, T , T ) }

| A |  =  1

Now according to the (classic) definition of probability we can write, that:

P ( A )  =  | A|/  | Ω |  =  1 /8

So finally we can write the answer:

The Probability of getting 3 tails in 3 coin flips is  1 /8 .

Step-by-step explanation:

Note how this drawing  is symmetrical about a horizontal line drawn halfway between AB and CD and passing through the origin.

Line AB has been subdivided into two equal pieces of length 15, so the length of AB is twice 15, or 30.  Due to the symmetry shown, line CD has the same length:  30.

Answer:

Michael should get $0.25 from the clerk.  

Step-by-step explanation:

Add $1.25+$0.50 together which equals $1.75 and multiply $0.25x8 which equals $2.00 and subtract $1.75 from $2.00 and that equals $0.25.

Answer:

.25 = 1 quarter

Step-by-step explanation:

8 x .25 = $2.00

1.25 + .50 = $1.75

2.00 - 1.75 = .25

Answer:

ur steps would be 9*1*9  = 9^3

Step-by-step explanation:

Any number in the power of 0 = 1

Answer:

9^4

Step-by-step explanation:

Let's review the equation:

9 · 9^0 · 9^3

Anything to the power of 0 is equal to one, so 9^0 is one

That leaves us with 9 · 1 · 9^3

9 · 1 = 9

9^1 · 9^3 = 9^4

so..

9 · 9^3

Answer:

Step-by-step explanation:

Let  n=2α⋅5β⋅m , where  gcd(m,10)=1 . Then, the decimal expansion of  1n  is of the form

0.a1…akak+1…ak+ℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(1) ,

where  k=max{α,β}  and  ℓ  is the least positive integer for which  m∣(10ℓ−1) . In other words,  ℓ  is the order of  10  in the multiplicative group of units modulo  m . So  ℓ∣ϕ(m)  by Lagrange's theorem.

In particular, if  gcd(n,10)=1 , then  α=β=k=0 ,  m=n , and

1n=0.a1…aℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(2)  

Therefore, we know that

117=0.a1…aℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(3)  

Here  ℓ  is the least positive integer for which  17  divides  9…9ℓtimes , and we know that  ℓ  divides  ϕ(17)=16 .

Successively squaring  10  modulo  17  gives

102≡−2(mod17),104≡4(mod17),108≡−1(mod17),1016≡1(mod17) .

So  ℓ=16  in expansion  (3) .

In fact,

a1…a16×17=1016–1.  

a1…a8+a9…a16=108−1 .

The first fact has nothing to do with the denominator  n  being prime. The second fact has everything to do with  n  being prime, and was discovered by E. Midy in  1836 .

Answer:

We can get 27 pieces of wire 3.6 cm long and have a piece 7/9 cm left over

Step-by-step explanation:

Find the "unit length" by dividing 1 m by 3.6 cm:

  1 m

-----------

3.6 cm

Recall that 1 m = 100 cm.  Multiply the following by the conversion factor 100 cm / 1 m:

  1 m            100 cm

----------- * ----------------- = 27,7777777...

3.6 cm            1 m

We can get 27 pieces of wire 3.6 cm long and have a piece 7/9 cm left over (verify this by dividing 7 by 9 on a calculator).

Answer:

Pieces can be cut = 1/3.6

Pieces can be cut = 0.27 m

100 cm = 1 m

0.27 m = 27 cm

Therefore,

The length remaining of wire is 27 cm (approximately)

Answer:

The angle formed between CF and the plane ABCD is approximately 47.14°

Step-by-step explanation:

The given parameters are;

BC = 6.8

DE = 9.3

∠BAC = 52°

We note that the angles formed by the vertex of a cuboid are right triangles, therefore, by trigonometric ratios, we get;

sin∠BAC = BC/(The length of a line drawn from A to C)

∴ The length of the line drawn from A to C = BC/sin∠BAC

The length of the line drawn from A to C = 6.8/sin(52°) ≈ 8.63

∴ AC = 8.63

By trigonometry, we have;

The angle formed between CF and the plane ABCD = Angle ∠ACF

[tex]tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length}[/tex]

[tex]tan\angle ACF = \dfrac{FA}{AC}[/tex]

In a cuboid, FA = BG = CH = DE = 9.3

[tex]\therefore tan\angle ACF = \dfrac{9.3}{8.63}[/tex]

[tex]\therefore \angle ACF = arctan \left(\dfrac{9.3}{8.63} \right) \approx 47.14^{\circ}[/tex]

The angle formed between CF and the plane ABCD = Angle ∠ACF ≈ 47.14°

Answer:

y=-2x+5

Step-by-step explanation:

slope is going down 2 over 1

y-int is 5

Answer:

It is y>-10

Step-by-step explanation:

i did it and i got it right.

The inequality that represents elevations above -10 meters is y > -10.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

The inequality y > -10 means that the elevation y of a passage is greater than -10 meters.

This represents all the elevations of passages that are above -10 meters, which is the given condition in the problem.

If the elevation is exactly -10 meters or below, then it does not meet the condition of being above -10 meters.

Therefore, any elevation that is greater than -10 meters satisfies this inequality, and any elevation that is less than or equal to -10 meters does not.

Thus,

The inequality that represents elevations above -10 meters is y > -10.
