The calculated time of is that the baseball game was 1 7/12 hour longer than the movie

The given parametes in the question are

Movie = 1 3/4 hours

Baseball = 3 1/3 hours

To calculate how much longer was the baseball game than the movie, we subtract

So, we have

Longer = 3 1/3 - 1 3/4

Evaluate

Longer = 19/12

Answer:

the probability of winning the bet is 4/9 or approximately 0.444 or 44.44%.

Step-by-step explanation:

To calculate the probability of winning a bet given odds in favor, we can use the following formula:

Probability of winning = Odds in favor / (Odds in favor + Odds against)

In this case, the odds in favor are given as 4 to 5. This means that for every 4 favorable outcomes, there are 5 unfavorable outcomes.

Plugging these values into the formula:

Probability of winning = 4 / (4 + 5)

Probability of winning = 4 / 9

So, the probability of winning the bet is 4/9 or approximately 0.444 or 44.44%.

The probability 0.7977 that the sample mean weight of 12 adult male passengers is greater than 162 lb.

There is a 79.77% chance that the elevator is overloaded

We can use the Central Limit Theorem here, which states that the sample mean of a sufficiently large sample size (n≥30) will be approximately normally distributed with mean μ and standard deviation σ/√n, where μ is the population mean and σ is the population standard deviation.

In this case, n=12, μ=169 lb, and σ=29 lb. Therefore, the sample mean weight of 12 adult male passengers will be approximately normally distributed with mean 169 lb and standard deviation 29/√12 ≈ 8.38 lb.

Now we can standardize this distribution to find the probability that the sample mean weight is greater than 162 lb:

z = (162 - 169) / 8.38 ≈ -0.83

We determine that the probability of z being less than or equal to -0.83 is approximately 0.2023, which can be calculated using a standard normal distribution table or calculator.

Therefore, there is a probability of 1 - 0.2023 ≈ 0.7977 that the sample mean weight of 12 adult male passengers is greater than 162 lb.

This indicates that if the elevator is filled with 12 adult male passengers, there is a 79.77 percent chance that it will be overloaded. The elevator does not appear to be safe for this many passengers, and this is a very high probability

Since the remainders are zero x³ - 1 is divisible by x - 1 and x³ -  8 is divisible by x - 2. The results can be used to find the slopes.

Polynomial long division is a method used to divide one polynomial by another polynomial. It is similar to the long division of integers.

The process involves dividing the highest degree term of the dividend by the highest degree term of the divisor to obtain the first term of the quotient, and then multiplying the entire divisor by this term and subtracting it from the dividend.

Here we have      

Show that x³ -1 is divisible by x - 1

Use polynomial long division to show that x³ - 1 is divisible by x - 1

        x² + x + 1

x - 1 | x³ + 0x² + 0x - 1

        x³ - x²  

               x² + 0x

                x² - x  

                  x - 1

                  x - 1  

                     0

Since the remainder is zero x³ - 1 is divisible by x - 1

Use polynomial long division to show that x³ - 8 is divisible by x - 2

           x² + 2x + 4

  x - 2 | x³ + 0x² + 0x - 8

            x³ - 2x²

                  2x² + 0x

                  2x² - 4x

                           4x - 8

                           4x - 8

                               0

Since the remainder is zero x³ -  8 is divisible by x - 2

These results can be useful in finding the slope of a certain curve.

Specifically, if we consider the curve y = x³, then we can use the fact that x³ - 1 is divisible by x - 1 and x³ - 8 is divisible by x - 2 to find the slope of the tangent line to the curve at the points (1,1) and (2,8), respectively.

Using the quotient rule of differentiation, find the derivative of y = x³ as:

=> dy/dx = 3x²

At x = 1, the slope of the tangent line is therefore 3.

At x = 2, the slope of the tangent line is also 3.

Therefore,

Since the remainders are zero x³ - 1 is divisible by x - 1 and x³ -  8 is divisible by x - 2. The results can be used to find the slopes.

"If you share 7 apples equally with 3 people, then there are 2 1/3 apples for each person."The whole number 2 represents the number of apples that each person will get when sharing 7 apples equally with 3 people.

A possible real-life application for the expression 1 ÷ 1/4 is dividing a pizza into quarters and then sharing one slice of pizza equally among a group of people.

To simplify the expression for sharing, we need to remember that dividing by a fraction is the same as multiplying by its reciprocal. So, 1 ÷ 1/4 is equivalent to 1 × 4/1, which simplifies to 4.

=The total surface area of the rectangular prism is 192 square inches.

You calculate the total surface area of the rectangular prism using the dimensions provided in the net. Since the net has 6 rectangular faces, we can find the area of each face and then sum them up to get the total surface area.

1. Top rectangle (8 inches by 3 inches): Area = length × width = 8 × 3 = 24 square inches.
Since the bottom rectangle is the same, its area is also 24 square inches.

2. Left rectangle (4 inches by 6 inches): Area = length × width = 4 × 6 = 24 square inches.
As the right rectangle is identical, its area is also 24 square inches.

3. Middle rectangle (8 inches by 6 inches): Area = length × width = 8 × 6 = 48 square inches.
The back rectangle is the same, so its area is 48 square inches as well.

Now, we'll sum up the areas of all 6 faces to get the total surface area:

Total Surface Area = (2 × 24) + (2 × 24) + (2 × 48) = 48 + 48 + 96 = 192 square inches.

Given that Marty has 6 gallons of orange juice, we can calculate the total amount in pints as follows:

So, Marty has 768 pints of orange juice.

Answer:

To factor the quadratic equation y = x^2 - 8x - 9, we need to find two numbers that multiply to give -9 and add to give -8 (the coefficient of the x term).

We can start by looking for two factors of -9 that add up to -8. The only pair of factors that works are -9 and 1. This is because (-9) + 1 = -8, and (-9) times 1 is -9.

Now we can use these factors to express the middle term of the quadratic in terms of two separate terms that can be factored by grouping. We can do this by splitting the -8x term into -9x + x:

y = x^2 - 9x + x - 9

Now we can group the first two terms together and the last two terms together:

y = (x^2 - 9x) + (x - 9)

We can factor out x from the first group, and factor out -9 from the second group:

y = x(x - 9) + (-9)(x - 9)

Finally, we can factor out the common factor of (x - 9):

y = (x - 9)(x - 1)

Therefore, the factor form of the quadratic equation y = x^2 - 8x - 9 is (x - 9)(x - 1).

Answer:

The formula for calculating the future value of a present amount with compound interest is:

FV = PV * (1 + r)^n

where FV is the future value, PV is the present value, r is the annual interest rate (as a decimal), and n is the number of compounding periods.

In this case, Nkaiseng wants to invest some money now to retire with R500 300 in 40 years (from 25 to 65). The annual interest rate is 11.5%, which is equivalent to a monthly interest rate of 0.115/12 = 0.00958.

So we have:

FV = PV * (1 + 0.00958)^ (40*12)

500300 = PV * (1.00958)^480

Dividing both sides by (1.00958)^480, we get:

PV = 500300 / (1.00958)^480

PV = 500300 / 20.4524

PV = 24406.53

Therefore, Nkaiseng should invest R24406.53 (rounded up to the nearest rand) now to have R500 300 when she retires at 65 years with an interest rate of 11.5% per annum.

L = x - y

L = 250/tan(32°) -  250/tan(68°)

L = 250{1/tan(32°) - 1/tan(68°)}

L = 250{1/(0.63) - 1/(2.48)}
