Answer:

\(x=\frac{1+\sqrt{31}}{2},\:x=\frac{1-\sqrt{31}}{2}\)

Step-by-step explanation:

\(-> 0=2x^2-2x-15\)

-zeros means the solution aka x intercept, meaning y=0

\(x_{1,\:2}=\frac{-\left(-2\right)\pm \sqrt{\left(-2\right)^2-4\cdot \:2\left(-15\right)}}{2\cdot \:2}\)

=> according to quadratic formula

\(x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\)

where \(ax^2+bx+c=0\)

=> \(x_{1,\:2}=\frac{-\left(-2\right)\pm \:2\sqrt{31}}{2\cdot \:2}\)

simplify

\(x_1=\frac{-\left(-2\right)+2\sqrt{31}}{2\cdot \:2},\:x_2=\frac{-\left(-2\right)-2\sqrt{31}}{2\cdot \:2}\)

\(x=\frac{1+\sqrt{31}}{2},\:x=\frac{1-\sqrt{31}}{2}\)

the correct format for a multiple regression equation is

ŷ= \(b_{o} + b_{1}x_{1} + b_{2}x_{2} + b_{3}x_{3} + b_{4}x_{4}\)

multiple regression: The relationship between a single dependent or criterion variable and multiple independent or predictor variables is typically explained by multiple regression. The constant term and multiple independent variables with their corresponding coefficients are used to model a dependent variable. The term "multiple regression" refers to the fact that it requires two or more predictor variables.

because, the weight of a passenger vehicle, in kilograms, is related to its length, in centimeters; and the maximum number of passengers.

thus, ŷ=\(b_{o} + b_{1}x_{1} + b_{2}x_{2} + b_{3}x_{3} + b_{4}x_{4}\) is the multiple regression equation.

The two quantities to be inversely proportional to each other  when one quantity's value rises relative to another's decline or vice versa

What is Proportionality?

The two sequences of numbers are proportional or directly proportional if the ratio between the corresponding elements of two sequences of numbers, typically experimental data, is constant and is known as the coefficient of proportionality constant.

When one quantity's value increases relative to another's drop or vice versa, they are said to be inversely proportionate. It suggests that the two quantities have different fundamental behaviors. For instance, there is an inverse relationship between time and speed.

As you increase the speed, the time gets shorter. Other names for this type of percentage in this context include reciprocal proportion, inverse proportion, oscillating inversely, and inverse variation. The expression for X and Y, two variables having inverse proportions, is;

x 1/y or x y-1

As a result, when one quantity's value increases in comparison to another's decrease or vice versa, the two values are said to be inversely proportional to one another.

The Robinsons can expect to save approximately $98.10 annually with their new dryer and will need to use it for 10.45 years to make up for the initial cost of $1,025.00.

To calculate the number of years it will take for the new dryer to pay for itself, we need to determine the amount of money the Robinsons will save annually with the new dryer.
The old dryer cost $545 per year to run, while the new dryer will save 18% annually in energy costs.
To find out how much the new dryer will cost to run annually, we can multiply the old cost by (100%-18%) or 82%.
$545 x 0.82 = $446.90
This means that the Robinsons will save $545 - $446.90 = $98.10 annually with the new dryer.
To determine how many years it will take for the new dryer to pay for itself, we need to divide the cost of the new dryer by the annual savings.
$1,025.00 / $98.10 = 10.45 years
Therefore, it will take approximately 10.45 years for the new dryer to pay for itself in energy cost savings.
In conclusion, the Robinsons can expect to save approximately $98.10 annually with their new dryer and will need to use it for 10.45 years to make up for the initial cost of $1,025.00.

Answer:

12.73 mins

Step-by-step explanation:

velocity: 9.9 mi/h

convert to minutes: 2.1/9.9 x 60 = 12.73 min

The minimum possible surface area of the box is \(4(2\times 2500)^{(2/3)} = 316.23 cm^2\) (rounded to two decimal places).

Let the side length of the square base be "s" and the height of the box be "h". Then, the volume of the box can be expressed as:

\(V = s^2 \times h\)

We know that V = 2500 \(cm^3\), so we can solve for "h" in terms of "s":

\(h = V / (s^2)\\h = 2500 / (s^2)\)

To minimize the surface area of the box, we need to minimize the sum of the area of the base and the area of the four sides. The area of the base is s^2, and the area of each of the four sides is s * h. Therefore, the surface area can be expressed as:

\(A = s^2 + 4sh\\A = s^2 + 4s(V / s^2)\\A = s^2 + 4V / s\)

To minimize the surface area, we need to take the derivative of A with respect to s, set it equal to zero, and solve for s:

\(dA/ds = 2s - 4V / s^2 = 0\\2s = 4V / s^2\\s^3 = 2V\\s = (2V)^{(1/3)\)

Substituting this value of s back into the expression for A, we get:

\(A = s^2 + 4V / s\\A = (2V)^{(2/3) }+ 4V / (2V)^{(1/3)}\\A = 4(2V)^{(2/3)\)

Alex purchases 13 cans of tomatoes and the remaining 19 cans are corn.

Let's assume that Alex buys 'x' cans of tomatoes. Since he buys a total of 32 cans of vegetables, he must buy the remaining (32 - x) cans of corn. According to the given information, each can of tomatoes costs 80 cents, and each can of corn costs 40 cents.

The cost of x cans of tomatoes is calculated as 80x cents, and the cost of (32 - x) cans of corn is calculated as 40(32 - x) cents. Adding these two costs together, we get the total cost of $18, which is equivalent to 1800 cents.

So, the equation can be formed as follows:

80x + 40(32 - x) = 1800

Now, let's solve this equation:

80x + 1280 - 40x = 1800

40x + 1280 = 1800

40x = 520

x = 520/40

x = 13

Therefore, Alex buys 13 cans of tomatoes.

The overlapping area between the line y = x - 6 and the curve y = 6/x and evaluating the integer coordinates within this region, we find that there are 13 lattice points contained in R.

The region defined by the simultaneous conditions x - y < 6, xy < 6, and x > 0 can be determined by graphing the inequalities.

However, since the question asks for the number of lattice points in the region, we can solve it algebraically.

First, let's consider the condition x - y < 6. If we rearrange this inequality, we get y > x - 6. This represents a region above the line y = x - 6 on the coordinate plane.

Next, let's analyze the condition xy < 6. We can rewrite this inequality as y < 6/x.

This represents a region below the curve y = 6/x.

To find the region that satisfies both conditions, we need to identify the overlapping area between the line y = x - 6 and the curve y = 6/x. This overlapping area is our region of interest, denoted as R.

To determine the lattice points within R, we need to find the integer coordinates (x, y) that satisfy both inequalities.

Since x > 0, we can start by evaluating the integer values of x from 1 to 5. For each x-value, we can calculate the corresponding y-value using the equation y = x - 6. If this y-value is less than 6/x, it satisfies both conditions and is considered a lattice point within R.

For example, when x = 1, y = 1 - 6 = -5, which is less than 6/1. So the lattice point (1, -5) is within R.

By repeating this process for x = 2, 3, 4, and 5, we can determine the other lattice points within R.

After evaluating all possible integer values of x, we find that R contains a total of 13 lattice points.

Therefore, the answer to the question is that the region R contains 13 lattice points.

Therefore, the probability that in any given minute there will be 2 or fewer arrivals is approximately 0.4231 or 42.31%.

To find the probability of 2 or fewer arrivals in a given minute, we can use the Poisson distribution formula.

The formula for the Poisson distribution is:

P(X = k) = (e*(-λ) * λ\(^k\)) / k!

Where:

P(X = k) is the probability of k arrivals,

e is the base of the natural logarithm (approximately 2.71828),

λ is the average rate of arrivals,

k is the number of arrivals.

In this case, the average rate of arrivals is given as 3 per minute.

Let's calculate the probabilities for k = 0, 1, and 2.

For k = 0:

P(X = 0) = (e⁻³ * 3⁰) / 0! = e⁻³ ≈ 0.0498

For k = 1:

P(X = 1) = (e⁻³ * 3¹) / 1! = 3e⁻³ ≈ 0.1493

For k = 2:

P(X = 2) = (e⁻³ * 3²) / 2! = 9e⁻³ / 2 ≈ 0.224

To find the probability of 2 or fewer arrivals, we sum up the probabilities for k = 0, 1, and 2:

P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)

= 0.0498 + 0.1493 + 0.224
