Answer:

x = 1

Step-by-step explanation:

The factors of the given expression is as follows:

\(7x(x^2-1) -3(x^2-1)\\\\7x^3 - 7x - 3x^2 +3\\\\7x^3 - 3x^2 -7x + 3\)

If we considered x = 1

So

7 - 3 -7 + 3 = 0

0 = 0

Hence, the factor would be x = 1

Option d is correct, ,\(ac+ad+ae+bc+bd+be\) is the equivalent expression of \((a+b)(c+d+e).\)

The expression \((a+b)(c+d+e)\) can be expanded using the distributive property.

We multiply each term in the first set of parentheses by each term in the second set of parentheses and combine like terms.

\((a+b)(c+d+e) = a(c+d+e) + b(c+d+e)\)

Expanding further:

\((a+b)(c+d+e) = ac + ad + ae + bc + bd + be\)

Hence,\(ac+ad+ae+bc+bd+be\) is the equivalent expression of \((a+b)(c+d+e).\)

The bond should sell for approximately $500.94 today. So, the correct answer is c.501.87.

To determine the price of the zero-coupon bond, we can use the formula for present value (PV) of a bond. The formula is:

PV = F / (1 + r)^n

Where:
PV is the present value of the bond,
F is the future value or par value of the bond ($1,000 in this case),
r is the yield to maturity (9% in this case),
n is the number of years until maturity (8 years in this case).

Let's substitute the given values into the formula:

PV = $1,000 / (1 + 0.09)^8

Now, let's calculate the price of the bond using a calculator:

PV = $1,000 / (1.09)^8
PV = $1,000 / 1.9993996
PV ≈ $500.94

Therefore, the bond should sell for approximately $500.94 today.

Now, let's analyze the answer choices to find the closest match.

a.513.16
b.422.41
c.501.87
d.4873.69

The closest match to the calculated value of $500.94 is option c.501.87. So, the correct answer is c.501.87.

Answer:

C and D are parallel

Step-by-step explanation:

If b⊥c and b⊥d, then that means that they are both parallel because they both have a 90 degree anglewith line B.

Answer:

I'm assuming that is what it is asking. if b and c are perpendicular, that means they form 90 degrees on all angles. The same for b and d. So if both c and d are perpendicular to b, then they are parallel.

The distribution for the random variable follows the binomial distribution with p = 0.5.

The random variable representing the number of red cards observed in these four trials follows the binomial distribution with a probability of success of 0.5. Therefore, the correct answer is (b) the binomial distribution with p = 0.5.

Each trial consists of choosing one card from the set of 10 cards, and the probability of selecting a red card is 0.5 since there are 5 red cards out of 10 total cards. The trials are independent because after each selection, the chosen card is replaced, so the probability of selecting a red card remains the same for each trial.

The binomial distribution is suitable for situations where there are a fixed number of independent trials, and each trial has two possible outcomes (success or failure) with a constant probability of success. In this case, the random variable represents the number of successes (red cards) observed in four trials.

The probability mass function (PMF) for the binomial distribution is given by:

P(X = k) = C(n, k) * p^k * (1-p)^(n-k)

Where X is the random variable, k is the number of successes, n is the number of trials, p is the probability of success, and C(n, k) represents the binomial coefficient.

n = 4 (four trials), p = 0.5 (probability of selecting a red card), and we are interested in finding P(X = k) for different values of k (0, 1, 2, 3, 4) representing the number of red cards observed in the four trials.

The midpoint of the coordinate pq is (-7.5, -5.5) while the distance between the two coordinate points is 5√2

The midpoint of a line is the coordinate point that divides the coordinates into two equal parts.

The formula for calculating the midpoint is expressed as:

\(m(x,y)=(\frac{x_1+x_1}{2} ,\frac{y_1+y_2}{2} )\)

Given the coordinate points p(-10, -8) and (-5, -3).

Calculate the midpoint of pq

\(m(x,y)=(\frac{-10-5}{2} ,\frac{-8-3}{2} )\\m(x,y)=(\frac{-15}{2} ,\frac{-11}{2} )\\m(x,y)=(-7.5,-5.5)\)

Hence the midpoint of the coordinate pq is (-7.5, -5.5)

According to the regression model, if the car you are thinking of buying has a 200-horsepower engine, the model suggests that your gas mileage would be approximately 30.07 miles per gallon.

Regression analysis is a statistical method used to examine the relationship between two or more variables. In this case, the study examined the relationship between fuel economy (measured in miles per gallon, or mpg) and horsepower for a sample of 15 car models. The resulting regression model allows us to make predictions about gas mileage based on the horsepower of a car.

The regression model given is:

mpg = 46.87 - 0.084(HP)

In this equation, "mpg" represents the predicted gas mileage, and "HP" represents the horsepower of the car. By plugging in the value of 200 for HP, we can calculate the predicted gas mileage for a car with a 200-horsepower engine.

To do this, substitute HP = 200 into the regression equation:

mpg = 46.87 - 0.084(200)

Now, let's simplify the equation:

mpg = 46.87 - 16.8

mpg = 30.07

The period of the pendulum (t) is approximately 4.77 seconds.

The formula for a basic pendulum's period is

T = 2π√(L/g)

where L is the pendulum's length and g is its gravitational acceleration.

Substituting the given values, we get:

T = 2π√(5.64/9.8)

Simplifying the expression inside the square root, we get:

T = 2π√(0.5755)

Calculating the square root, we get:

T = 2π(0.759)

Multiplying by 2 and π, we get:

T = 4.77 seconds (rounded to two decimal places)

Bryant Industries uses forecasting to estimate the number of orders that will be placed by their customers. The table below gives the sales figures for the last four months.Month2345Sales92491942004There are different forecasting techniques used by companies like Bryant Industries to predict future sales.

One of the most widely used methods is the time-series method. This method is particularly useful when the demand for a product or service changes over time and when there are no external factors that affect the sales. In this case, we can use a time-series method called the moving average to estimate future sales. The moving average is a time-series method that uses the average of past sales data to estimate future sales. It is particularly useful when there are no external factors that affect the sales. In this case, we can use a 3-month moving average to estimate future sales. The 3-month moving average is calculated as follows: (924 + 919 + 420) / 3 = 754.33. This means that we can expect sales of around 754 units next month. The moving average method is easy to use and is a good way to get a quick estimate of future sales. However, it has some limitations. For example, it does not take into account external factors that may affect sales, such as changes in the economy or in consumer behavior.

In conclusion, Bryant Industries can use the moving average method to estimate future sales. However, they should also consider other factors that may affect sales, such as changes in the economy or in consumer behavior.

Answer:

The ball will spend 10,730.4012 microseconds in the strike zone

Step-by-step explanation:

Here, we want to calculate the time spent by a ball in the strike zone given the distance across the strike zone and the speed of the ball

Mathematically, we have ;

time = distance/speed

Before we proceed to use this formula, we need to have the parameters in the same units

So let’s convert 17 inches to miles

Mathematically;

1 inch = 1.578 * 10^-5 mile

So 17 inches = 1.578 * 10^-5 * 17 = 0.00026826 miles

So let’s now calculate the time

That will be;

0.00026826/90 = 0.000002980667 hours

It will be best if we convert this to seconds

Mathematically,

60 seconds = 1 minute

60 minutes = 1 hour

So the number of seconds in an hour is 60 * 60 = 3600 seconds

= 0.000002980667 * 3600 = 0.0107304012

Mathematically, 1 second = 10^6 microseconds

Thus multiplying 0.0107304012 by 10^6

we have; 10,730.4012 micro seconds

The equation that represents the situation is x/2 - 3 = 79, and the number of points that scored by Bulls is 164 points

The total points scored by Miami Heat = 79 points

This was 3 less than half the point the Chicago Bull scored.

Consider the Chicago Bull scored x points

Then the equation will be

x/2 - 3 = 79

Move 3 to the right hand side of the equation

x/2 = 79 + 3

Add the numbers

x/2 = 82

Move the 2 to the right hand side of the equation

x = 82 × 2

Multiply the numbers

x = 164 points

Therefore, the Bull scored 164 points
