Determine if the sequence below is arithmetic or geometric and determine
the common difference / ratio in simplest form.
64, 16, 4, ...

Step-by-step explanation:

a probability is always

desired cases / totally possible cases

a 50% probability means 1/2 or 0.5.

that means

desired cases = 1/2 × totally possible cases

at start we have

3 red

3 white

5 blue

that makes 5 + 3 + 3 = 11 totally possible cases and 3 desired cases.

so, the starting probability to pull a white marble is

3/11.

now, we need to say

(3 + x) = 1/2 × (11 + x) (= (3+x)/(11+x) = 1/2)

to make is simpler we multiply both sides by 2 (so we get rid of the 1/2 fraction).

6 + 2x = 11 + x

6 + x = 11

x = 5

we need to add 5 white marble to give us a 50% probability to pull a white marble.

we have then

3 red

3 + 5 = 8 white

5 blue

that makes 5+8+3 = 16 totally possible cases and 8 desired cases.

so, the probability is

8/16 = 1/2

=> our calculation was correct

The number of white marbles should be added to the bag to make the probability of pulling a white marble 50% will be 5.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

A bag contains 3 red marbles, 3 white marbles, and 5 blue marbles. only white marbles will be added to the bag.

Let 'x' be the number of white marble added. Then the equation is given as,

0.50 = (x + 3) / (x + 3 + 3 + 5)

Simplify the equation, then we have

0.50 = (x + 3) / (x + 3 + 3 + 5)

0.50 = (x + 3) / (x + 11)

0.50x + 5.5 = x + 3

0.50x = 2.5

x = 5

The number of white marbles should be added to the bag to make the probability of pulling a white marble 50% will be 5.

Answer:

The probabilities in this problem are given as follows:

A. False - negative: 0.08 = 8%.

B. True - negative: 0.48 = 48%.

C. False-negative given that the result is negative: 0.1429 = 14.29%.

Conditional probability is the probability of one event happening, considering a previous event. The formula is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which the parameters of the formula are given as follows:

The probability of a false negative is composed as follows:

Hence:

P(FN) = 0.2 x 0.4 = 0.08 = 8%.

The probability of a true negative is composed as follows:

Hence:

P(TN) = 0.8 x 0.6 = 0.48 = 48%.

The probability of negative results is:

P(N) = P(FN) + P(TN) = 0.08 + 0.48 = 0.56.

Hence the conditional probability is given by:

P(FN|N) = 0.08/0.56 = 0.1429 = 14.29%.

Step-by-step explanation:

You want the side opposite a 24° angle in a right triangle with a hypotenuse of 14 units.

The sine relation is ...

  Sin = Opposite/Hypotenuse

  sin(24°) = x/14

Solving for x, we get ...

  x = 14·sin(24°) ≈ 5.69

The side lengths of the truss which is an isosceles triangle are 13 feet , 4 feet and 4 feet.

In geometry, an isosceles triangle  is a triangle with at least two sides of identical length. It can be defined as having exactly two equal-length sides or as having at least two equal-length sides, with the equilateral triangle being an exception to the second definition.

The base of the triangle is its third side, while its two equal sides are referred to as its legs. Simple formulas can be used to calculate the triangle's height, area, and perimeter from the lengths of the triangle's legs and base.

Let us consider the length of the longest side of the isosceles triangle be x.

Therefore length of smaller sides = x - 9

The perimeter of the triangle is given as 21 meters.

Therefore :

x + (x - 9) + (x - 9) = 21

or, 3x -18 = 21

or, 3x = 39

or , x = 13 feet

Therefore length of two smaller sides of the triangle = x - 9 = 4 feet

Therefore the length of the three sides of the triangle are

4 feet , 4 feet and 13 feet.

Using the midpoint theorem, the length of AM is 43

From the question, we are to determine the length of AM

From the given information,

Point M is the midpoint of AB

Thus,

From the midpoint theorem

We can write that

AM + MB = AB

AM = MB

AM + AM = AB

2AM = AB

Also, from the given information,

AM = 2x + 9

and

AB = 8x - 50

Therefore,

From 2AM = AB  

2(2x + 9) = 8x - 50

Solve for x

2(2x + 9) = 8x - 50

4x + 18 = 8x - 50

18 + 50 = 8x - 4x

68 = 4x

x = 68/4

x = 17

But,

AM = 2x + 9

Substituting the value of x

Thus,

AM = 2(17) + 9

AM = 34 + 9

AM = 43

This means the length of AM is 43

Step-by-step explanation:

[tex]\lim_{x \to \pi} \frac{\sin x}{2\sin x \cos x}\\\\=\lim_{x \to \pi} \frac{1}{2\cos x}\\\\=\frac{1}{2\cos \pi}\\\\=-\frac{1}{2}[/tex]

Answer:

[tex]-\frac{1}{2}[/tex]

Step-by-step explanation:

If we try direct substitution we get: [tex]lim_{x\to\pi}h(x)=\frac{sin(\pi)}{sin(2\pi)}[/tex]

The radian [tex]2\pi[/tex] is a full rotation from 0 radians, in other words it's equivalent to 0 radians.

Using the unit circle as a reference you'll remember when the angle is 0 radians, the y-value is zero, so: [tex]sin(2\pi)=0[/tex]

When the angle is: [tex]\pi[/tex] it's at a half rotation where the y-value is still zero on the unit circle.

So you get the indeterminate form of: [tex]\frac{0}{0}[/tex]

We can use L'Hôpital's rule which states: [tex]lim_{x\to c}\frac{f(x)}{g(x)}=lim_{x\to c}\frac{f'(x)}{g'(x)}[/tex] if the original limit is in indeterminate form such as the one above.

Taking the derivative of sin(x) we simply use the property that: [tex]\frac{d}{dx}[sin(x)]=cos(x)[/tex]

For the sin(2x) we can use the chain rule which essentially states: [tex]h(x)=f(g(x))\\h(x)=f'(g(x))*g'(x)[/tex]

It deals with composite equations, and in this case we can represent the composite function as:

[tex]f(x)=sin(g(x))\\g(x)=2x[/tex]

Using the chain rule we get: [tex]cos(2x)*2[/tex]

So now we have the limit: [tex]lim_{x\to \pi}\frac{cos(x)}{2cos(2x)}[/tex]

at pi radians the unit circle is at a half rotation where the x/y coordinates are: [tex](-1, 0)[/tex]

so cos(pi) = -1

at 2 * pi radians were basically back at 0 radians where the x/y coordinates are: [tex](1, 0)[/tex]

so cos(2 * pi) = 1

Now plugging in these values we get the fraction: [tex]\frac{-1}{2*1}[/tex] which just simplifies to: [tex]-\frac{1}{2}[/tex] which turns out to be the limit!

The expression 26+8 as the product of the GCF and a sum is:

2(13+4).

Given we have the expression as 26+8

We need to find the greatest common factor of the numbers 26 and 8.

26 = 2 × 13

8 = 2 × 2 × 2

Multiply all the prime factors that both numbers share in order to determine the GCF:

Therefore, GCF = 2

Answer:

Let the required number be ab.

Sum of digits = a + b ........ ( 1 )

10 a + b = 4 ( a + b )

10 a + b + 18 = 10 b + a

=> 9 a + 18 = 9 b

=> a + 2 = b

10 a + a + 2 = 4 ( a + a + 2 )

=> 11 a + 2 = 8 a + 8

=> 3 a = 6

=> a = 3

=> a + 2 = 5

=>ab = 35......... [ A ]

• (two-digit number) = 3 + 4(sum of its digits)

• (two-digit number) + 18 = Digit gets reverse

• The number.

-We will first assume the number on one's place be [tex]x[/tex] and ten's place be [tex]y[/tex] [why? because the given conditions are about the digits of number]

-Two-digit number then formed will be 10y + x and its reverse will be 10x + y[why? well let's take an example like a number 42. This number can be written in expanded form as 10×4+2×1 here 4 is number at ten's place (y) and 2 at one's place(x) It's reverse will be 24 it can be written in expanded form as 10×2+4×1 here 2 is number at ten's place (y) and 4 at one's place(x)]

-Then we will use given conditions to form the equation and will solve the equations to get the answer.

So now let's get started with our solution! :D

Let the one's and ten's digit of the number be [tex]x[/tex] and [tex]y[/tex] respectively.

According to first condition,

=> (10y + x) = 3 + 4(x + y)

=> 10y + x = 3 + 4x + 4y

=> 10y - 4y = 3 + 4x - x

=> 6y = 3 + 3x

[tex] \implies \sf \frac{6y}{3} = \frac{3}{3} + \frac{3x}{3} [/tex]

=> 2y - 1 = x ___(equation 1)

According to second condition,

=> (10y + x) + 18 = 10x + y

=> 10y - y + 18 = 10x - x

=> 9y + 18 = 9x

[tex] \implies \sf \frac{9y}{9} + \frac{18}{9} = \frac{9x}{9} [/tex]

=> y + 2 = x ___(equation 2)

Solving equation 1 and 2

y + 2 = x (equation 2)

y + 2 = 2y - 1 [From equation 1]

3 = 2y - y

3 = y (ten's place)

Now put value of y = 3 in equation 2

y + 2 = x (equation 2)

3 + 2 = x

5 = x (one's place)

So, the number formed is 35.

Step-by-step explanation:

c + r = 30            Eq. 1

4r + 8c = 144       Eq. 2

r = rectangular tables

c = circular tables

From Eq. 1:

c = 30 - r             Eq. 3

Replacing Eq. 3 in Eq. 2:

4r + 8(30-r) = 144

4r + (8*30 + 8*-r) = 144

4r + 240 - 8r = 144

-4r = 144 - 240

-4r = -96

r = -96/-4

r = 24

from Eq. 3

c = 30 - r

c = 30 - 24

c = 6

Check:

from Eq. 2

4r + 8c = 144

4*24 + 8*6 = 144

96 + 48 = 144
