Answer:

1 /81

Step-by-step explanation:

1/3 * 1/3 * 1/3 * 1/3 (One for each game) = 1/81

This question is based on the probability. Therefore, the approximate probability of winning 4 games in a row is [tex]\dfrac{1}{81}[/tex].

Given:

The probability of winning the shell games if you randomly pick is 1 in 3.

We need to calculate the approximate probability of winning 4 games in a row.

According to the question,

By using the formula of probability,

[tex]Probability = \dfrac{Number \, of \, favourable \, outcome}{Total \, number \,of\, Outcome}[/tex]

It is given that,  probability of winning is 1 in 3.

Now, calculating the approximate probability of winning 4 games in a row is,

[tex]\dfrac{1}{3} \times\dfrac{1}{3} \times \dfrac{1}{3} \times \dfrac{1}{3} = \dfrac{1}{81}[/tex]

Therefore, the approximate probability of winning 4 games in a row is [tex]\dfrac{1}{81}[/tex].

From factoring rules for the difference of squares, it is possible rewrite the equation [tex]16x^4-81[/tex] as (2x-3)(2x+3(4x²+9).

In math, the factoring or factorization is used to write an algebraic expression in factors.

The question gives a polynomial and asks your respective factorization. Note that [tex]16x^4-81[/tex] is a difference of squares. The factoring rules shows that the difference of squares: a² – b² = (a – b)(a + b).

If [tex]16x^4-81[/tex] is a difference of squares. You can rewrite this expression as:

[tex]16x^4-81=(4x^2-9)(4x^2+9)[/tex].

Again, you have another difference of squares: 4x²-9. You can rewrite this expression as: 4x²-9= (2x+3)(2x-3).

Hence, [tex]16x^4-81=(2x-3)(2x+3)(4x+9)[/tex].

Final answer:

The expression 16x^4 − 81 is a difference of squares and can be factored completely into (2x + 3)(2x − 3)(4x^2 + 9).

Explanation:

The student has asked to factor the expression 16x4 − 81 completely. This expression is a difference of squares, where 16x4 is the square of 4x2, and 81 is the square of 9. According to the difference of squares formula, a2 − b2 can be factored into (a + b)(a - b). Therefore, 16x4 − 81 can be factored as:

(4x2 + 9)(4x2 − 9)

Next, observe that 4x2 − 9 is another difference of squares, which can be further factored into (2x + 3)(2x − 3). Combining these factors, we get the completely factored expression:

(2x + 3)(2x − 3)(4x2 + 9)

Step-by-step explanation:

30% of the apples weigh less than 141 grams.

The z-distribution, also known as the standard normal distribution or the standard Gaussian distribution, is a probability distribution that is often used in statistics. It is a special case of the normal distribution with a mean of 0 and a standard deviation of 1.

First, we need to find the z-score corresponding to a cumulative probability of 0.30.

Using the z-distribution table, we find that the z-score corresponding to a cumulative probability of 0.30 is approximately -0.52.

The z-score formula is given by:

z = (x - μ) / σ

Where:

z is the z-score

x is the value we want to find the corresponding z-score for

μ is the mean of the distribution

σ is the standard deviation of the distribution

Rearranging the formula to solve for x:

x = zσ + μ

x = -0.52 (4.2) + 143

x ≈ 140.94

Therefore, 30% of the apples weigh less than 141 grams.

Answer: early redemption fee

Step-by-step explanation:

The type of fee charged for withdrawing money from a CD before the date of maturation is Early redemption fee.

We have to determine the type of fee charged for withdrawing money from a CD before the date of maturation.

We have given

A. FDIC fee

It required the largest taxpayer bailout in the year 2008 financial crisis, explained in a footnote on its schedule of fees for business accounts in the nation's  states that it charges an FDIC insurance fee at the annual rate of 13 cents per $100.

It related to insurance so it is not correct option.

B. Early redemption fee

The fee  may be required to make to a lender if we pay off a loan or mortgage before the scheduled term of the credit facility.

So the Banks and credit unions often charge a fee if you withdraw money before maturity.

Therefore the Option B is correct.

C. Liquidity fee

This is nothing but the  liquidity facility providers that the borrower may from time to time agree to pay.

Therefore this is not correct option

Step-by-step explanation:

Answer:

∠ H = 84°

Step-by-step explanation:

Since HI = IJ then Δ HIJ is isosceles with ∠ IHJ = ∠ IJH, thus

∠IHJ = [tex]\frac{180-134}{2}[/tex] = [tex]\frac{46}{2}[/tex] = 23°

Similarly

Since HG = JG then Δ HGJ is isosceles with ∠ GHJ = ∠ GJH, thus

∠ GHJ = [tex]\frac{180-58}{2}[/tex] = [tex]\frac{122}{2}[/tex] = 61°

Thus

∠ H = ∠ GJH + ∠ IHJ = 61° + 23° = 84°

The plumber able to cut the 5-meter long pipe into 50 sections, each measuring 10 centimeters.

To find the number of sections the plumber  able to cut from a 5-meter long pipe, to convert the length to centimeters.

That 1 meter is equal to 100 centimeters. So, to convert 5 meters to centimeters, multiply 5 by 100:

5 meters × 100 centimeters/meter = 500 centimeters

Now that the length of the pipe in centimeters (500 cm), divide it by the desired length of each section, which is 10 centimeters:

The statements that follows the Expressions are:

The solution is the product of two factors.

The first factor is itself the sum of two terms.

A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product because the product is divisible by them.

We can describe this expression as the product between a 5 and the sum of two 9 and 1, that is, the second factor is a sum of two terms, this means option A is a true statement.

As a product, the solution of this expression is the solution of that product, however, we first have to sum both terms inside the parenthesis, like this

= (9 + 1)5

= 10(5)

= 50

Answer: It takes Him 1/4 hours to decorate both signs,

Step-by-step explanation:

Hi, since the area of a rectangle is equal to:

Area: length x width

Replacing with the values given;

Sign 1 =A1 = 2/3 x 1/4 =1/6 ft2

Sign 2 =A2= 1/2 x 1/3 = 1/6 ft2

If we sum both areas:

A1 +A2 = 1/6 + 1/6 = 2/6 ft2 = 1/3 ft2 (total area)

Since it takes Roberto 3/4 hour to decorate a 1-square-foot sign:

For 1/3 ft2

3/4 hour x 1/3 ft2 = 1/4 h

ITt takes Him 1/4 hours to decorate both signs,

It takes Roberto 1/4 hour to decorate both signs.

To find the total amount of time it takes Roberto to decorate both signs, we need to calculate the area of each sign first and then determine the time required for each based on the given rate of 3/4 hour per 1 square foot.

1: Calculate the area of each sign

2: Calculate the total area of both signs

Total area (Atotal) = A1 + A2 = 1/6 + 1/6 = 2/6 = 1/3 square foot.

3: Calculate the total time to decorate both signs

It takes Roberto 3/4 hour to decorate 1 square foot. So, for 1/3 square foot:
Time = (3/4) × (1/3) = 1/4 hour.

Therefore, it takes Roberto 1/4 hour to decorate both signs.

x=3 one solution

Step-by-step explanation:

Let's solve your equation step-by-step.

−6x+19=x−2

Step 1: Subtract x from both sides.

−6x+19−x=x−2−x

−7x+19=−2

Step 2: Subtract 19 from both sides.

−7x+19−19=−2−19

−7x=−21

Step 3: Divide both sides by -7.

−7x /−7  =  −21 /−7

x=3

Answer:

x = 3

Step-by-step explanation:

Solve -6x + 19 = x-2

Solve for x:

19 - 6 x = x - 2

Subtract x from both sides:

19 + (-6 x - x) = (x - x) - 2

-6 x - x = -7 x:

-7 x + 19 = (x - x) - 2

x - x = 0:

19 - 7 x = -2

Subtract 19 from both sides:

(19 - 19) - 7 x = -19 - 2

19 - 19 = 0:

-7 x = -19 - 2

-19 - 2 = -21:

-7 x = -21

Divide both sides of -7 x = -21 by -7:

(-7 x)/(-7) = (-21)/(-7)

(-7)/(-7) = 1:

x = (-21)/(-7)

The gcd of -21 and -7 is -7, so (-21)/(-7) = (-7×3)/(-7×1) = (-7)/(-7)×3 = 3:

Answer:

Step-by-step explanation:

23) a) n - (n+1)

Remove the parenthesis by multiplying (n+1) by (-1)

n - (n+1) = n - n - 1 = -1

b) n(n+1) = n*n + n*1

              = n² + n

c) When we are adding the two numbers it is,

n² + n - 1. This will always be odd because n² + n will always be even and when we subtract 1 from that it will be odd

Example: Take n = 3

n² + n =  3*3 + 3 = 9 + 3 =12; So, n² + n -1 = 12- 1 =11 --> odd

When n = 7

n² + n = 49 + 7 = 56 ; So, n² + n -1 = 56-1 = 55 ---> odd

When n =8

n² + n = 64 + 8 = 72;  So, n² + n -1 = 72 -1 = 71

When n = 16

n² + n = 256 +16 = 272 ; So, n² + n - 1 = 272 - 1 = 271 ----->odd
