Answer:

0.0078125

Step-by-step explanation:

Probability of tail, p = 0. 5

Probability of getting all tails from 7 tosses :

P(tail) * P(tail) * P(tail) * P(tail) * P(tail) * P(tail) * P(tail)

0.5 * 0.5 * 0.5 * 0.5 * 0.5 * 0.5 * 0.5 = 0.0078125

We could also use the binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - r)

n = 7 ; x = 7, p = 0.5,

P(x = 7) = 7C7 * 0.5^7 * 0.5^0 = 0.0078125

Answer:

x=18

Step-by-step explanation:

6/2= x/6

2x=36

Divide by 2

x=18

The measure of the hypotenuse AC will be AC=18

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or formerly rectangle triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and other angles of the right triangle.

Given that the right triangle ABC with altitude BD drawn to hypotenuse AC. and AB=6 and AD=2,

The value of AC will be calculated as:-

6 / 2= AC / 6

2 x AC=36

Divide by 2

AC = 18

Hence, the measure of AC is 19.

Answer:

16,384

Step-by-step explanation:

The pattern is times 2

2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384

The 14th term is 16384

The required 14th term of the given geometric sequence 2, 4, 8, is 16384.

The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.

The geometric sequence is given in the question as:

2, 4, 8, ...

To determine the 14th term of the geometric sequence 2, 4, 8, you can use the formula for the nth term of a geometric sequence, which is [tex]a_n = a_1 \times r^{(n-1)}[/tex], where [tex]a_n[/tex] is the nth term, [tex]a_1[/tex] is the first term, and r is the common ratio.

In this case, the first term is 2, the common ratio is 2, and the term you want to find is the 14th term, so you can plug these values into the formula to get:

[tex]a_{14} = 2 \times 2^{(14-1)}[/tex]

= 2 × 2¹³

= 2 × 8192

= 16384

Therefore, the 14th term of the geometric sequence is 16384.

Answer:

{ x | x < 2 or x > 8}

Step-by-step explanation:

Given the expression

(x + 3 < 5) U (x - 7 > 1).

Solve x+3 < 5

Subtract 3 from both sides

x+3 - 3 < 5-3

x < 2

For x - 7 > 1

Add 7 to both sides

x-7+7 > 1 + 7

x > 8

Hence the union of both is { x | x < 2 or x > 8}

Answer:

Any choice that has a slope of -1/2

Step-by-step explanation:

Answer:

x = 15

Step-by-step explanation:

The right angle is formed at at the tangent line and the radius

So to solve for the missing angle we can solve for x using the Pythagorean Theorem

The Pythagorean theorem states that the sum of the two legs squared equal the hypotenuse squared

Knowing this we can create an equation to solve for x

[tex]12^2+9^2=x^2[/tex]

now we solve for x

[tex]12^2=144\\9^2=81\\81+144=225\\225=x^2\\\sqrt{225} =15\\\sqrt{x^2} =x\\x=15[/tex]

So we can conclude that x = 15

Answer:

$68000

Step-by-step explanation:

Tax free earning = first 4000

Tax on remaining amount = 25%

Total earning in other to have $20000 net of tax earning :

Net of tax = tax free earning + (25% * remaining amount)

Let remaining amount = x

20000 = 4000 + (0.25 * x)

20000 = 4000 + 0.25x

20000 - 4000 = 0.25x

16000 = 0.25x

x = 16000 / 0.25

x = 64000

Hence,

Total earning should be :

Tax free earning + roaming amount

4000 + 64000

= $68000

Answer:

118

Step-by-step explanation:

the length ED is equal to EC

so

the angle is also the same

that's mean the angle ECD is equal to 31

then to find the another angle just do like this

=180–31–31

=118

Answer:

∠AEB = 118°

Step-by-step explanation:

∠EDC = 31°

∠ECD = ∠EDC = 31°

ΔDEC = contains 180°

∠DEC = 180 - 31 - 31 = 118°

∠AEB = 118° because it is a vertical angle to ∠DEC

I can't see pictures, but to graph y=2x, you have to make 2x into slope form.

Just write 2 as a fraction, or 2/1. 2 is the rise, and 1 is the run. So start at the origin, or (0,0), and go up 2 units, then 1 unit right. So you start at (0,0), then now you should be at (1,2). Repeat the process to make a straight line.

Richard and Teo have a combined age of 50. Richard is 14 years older than twice Teo's age. How old are Richard and Teo?

aswer..RICHARD IS 20YEARS ODL

AND TEO IS 9YEARS OLD

Answer:

Step-by-step explanation:

if you add all the angles in a triangle together, its 180 degrees.

so, (3x+2)+(4x+1)+(2x+1) = 180

we can combine like terms so 9x+4=180

                                                    9x=176

                                                       x=19.6 degrees

now plug the x into each angle and that's them
