The probability of a family having two boy children is 0.25, or 25%. This probability is determined by a simple calculation. If there are two children in the family, the probability of each child being a boy is 0.5 (50%), and the probability of both children being boys is 0.5 x 0.5, or 0.25 (25%).

When it comes to probability, the likelihood of an event is determined by the number of possible outcomes. In the case of this question, there are four possible outcomes: two boys, two girls, one boy and one girl, and one girl and one boy. Since each outcome is equally likely, each has a probability of 0.25 (25%).

It is important to note that the probability of a family having two boy children is the same as the probability of a family having two girls. In each case, the probability is 0.25 (25%). This is because the gender of a child is independent of the gender of their sibling.

In conclusion, the probability of a family having two boy children is 0.25 (25%). This probability is determined by the number of possible outcomes, each of which is equally likely. It is also important to note that this probability is the same for a family having two girls.

the inequality that describes the problem is x ≤ 210, meaning that Simon can drive at most 210 more miles before his electric car runs out of battery.

If Simon has driven 140 miles since fully charging his car, then the amount of charge remaining in the battery can power the car for x miles. We can set up the following inequality to represent this situation:

x ≤ 350 - 140

The amount of charge left in the battery is shown on the right-hand side of the inequality and is equal to the maximum amount of charge the battery can store (350 miles) minus the amount of charge that has already been utilised (140 miles). The left-hand side of the inequality displays the number of miles Simon can travel until his battery runs out, which is either less than or equal to the battery's remaining charge.

Simplifying the inequality, we get:

The probability that a student chosen at random likes science given that he or she likes art is 41.4%

In our case, we want to find P(Science|Art), which is the probability of a student liking science given that he or she likes art. Using Bayes' theorem, we have:

P(Science|Art) = P(Art|Science) x P(Science) / P(Art)

We know that P(Art) = 0.35 and P(Science|Art) = 0.22. To find P(Art|Science), we can use the formula:

P(Art|Science) = P(Science|Art) x P(Art) / P(Science)

We don't know P(Science) yet, but we can calculate it using the fact that:

P(Science) = P(Science|Art) x P(Art) + P(Science|Not Art) x P(Not Art)

where P(Not Art) is the probability that a student does not like art, which is 1 - P(Art) = 0.65. We are given that P(Science|Not Art) = 0.15, which is the probability that a student who does not like art likes science. Substituting these values, we get:

P(Science) = 0.22 x 0.35 + 0.15 x 0.65 = 0.1855

Now we can substitute all the values into Bayes' theorem:

P(Science|Art) = 0.22 x 0.35 / 0.1855 = 0.414 or 41.4%

Step-by-step explanation:

To find when people stop watching the video, we need to find the maximum point of the quadratic function y = -0.75x² + 9.75x.

The x-coordinate of the maximum point of a quadratic function can be found using the formula x = -b/2a, where a and b are the coefficients of the quadratic function.

Using the formula with a = -0.75 and b = 9.75, we get:

x = -9.75 / 2(-0.75)

x = -9.75 / -1.5

x = 6.5

Therefore, the maximum number of views per day will occur on the 6.5th day after the video was posted.

To determine when people stop watching the video, we need to check the values of y after this point.

When x > 6.5, the quadratic function becomes negative, which means that the number of views per day will start to decrease. Therefore, people stop watching the video after 6.5 days (or sometime around the 7th day).

so, x = (11 + [tex]\sqrt{-109}[/tex]) / 4 is not a real root because the square root of a negative number is not a real number. x = 9.140 and x = 1.855 are not roots of the polynomial.

The square root of a number is a value that, when multiplied by itself, gives the original number. In mathematical notation, the square root of a number "x" is represented by the symbol "√x". For example, the square root of 25 is 5, because 5 multiplied by 5 equals 25.

Given by the question.

To find the roots of the polynomial [tex]x^{2}[/tex] - 11x + 17, we can use the quadratic formula:

x = ([tex]\sqrt{b^{2}-4ac }[/tex]) / 2a

Here, a = 1, b = -11, and c = 17.

Substituting these values into the quadratic formula, we get:

x = (11 ± [tex]\sqrt{11^{2}-4(1)(17) }[/tex]) / 2(1)

Simplifying this expression, we get:

x = (11 ± [tex]\sqrt{53}[/tex]) / 2

Therefore, the two roots of the polynomial are:

x = (11 + [tex]\sqrt{53}[/tex]) / 2 and x = (11 - [tex]\sqrt{53}[/tex]) / 2

x= (11+7.280)/2 and x = (11-7.280)/2

x= 18.280/2 and x = 3.71/2

Let's start at (0,5) then count down 2 points, which is the "Rise"(seems like an interesting name to pick but it works).
Next, you go to the right once. Which counts as the "Run".

Remember: The slope is like a ratio, and the "y" will always go as the numerator and the "x" as the denominator. Which is why "Rise" is on top and the "Run" is on the bottom.

So your answer would be 2/1. And that simplifies to 2. But since you went down and not up, it would be negative 2.

The equation of the line that contains the point (-6, 5) and is parallel to x + 2y = 14 in slope-intercept form is y = (-1/2)x + 2.

Due to their similar slopes, parallel lines move in the x direction with the same rate of change. If we know the slope of a line, we can use that slope to determine the slope of any line that is parallel to it. The point-slope form of a line can be used to get the equation of a line that is parallel to a given line and passes through a specified point.

The given equation of the line is:

x + 2y = 14

Rewriting the equation in standard form we have:

y = (-1/2)x + 7

where, -1/2 is the slope of the line.

The slope of two parallel lines are equal. Thus the slope of new line is m = -1/2.

Now, using the point slope form:

y - y1 = m(x - x1)

Substitute the values:

y - 5 = (-1/2)(x - (-6))

y - 5 = (-1/2)x - 3

y = (-1/2)x + 2

Hence, the equation of the line that contains the point (-6, 5) and is parallel to x + 2y = 14 in slope-intercept form is y = (-1/2)x + 2.

Just Because They Produce more Automobiles, does not mean they sell them all, which it also does not tell us the quantity.

The graph of the equation is a parabola with its vertex at (10, 0), and it can also be used to calculate the diameter of the lesion for any given time.

Suppose a medical researcher constructs a mathematical model describing the size of a lesion. The model that describes the diameter of a lesion in cm as function of time(days) is given by [tex]D(t)= (t-10)^2[/tex]; 0. We will solve this problem by finding the answer step by step. FunctionThe function of the lesion's size over time is provided by the equation D(t)= (t-10)2, where t is the time in days and D(t) is the diameter of the lesion at the time t.

The origin of this equation is given by D(t) = f(t), where the variable t represents the independent variable, and the variable D(t) represents the dependent variable. To calculate the diameter of the lesion over time, substitute values of t into the equation D(t) = (t-10)2. When t = 0, for instance, D(0) = (0-10)2 = 100. This means that the lesion's diameter at time zero is 100cm.

The model's interpretation The mathematical model that describes the diameter of a lesion as a function of time was created by a medical researcher. The equation D(t) = (t-10)2 represents this model. The researcher's model indicates that the diameter of the lesion is equal to the square of the difference between the time and ten. The difference between the time and ten is squared, which means that the model represents a parabolic curve.

The question is, "Suppose a medical researcher constructs a mathematical model describing the size of a lesion. The model that describes the diameter of a lesion in cm as a function of time (days) is given by D(t)= (t-10)^2; answer in 200 words."
The given equation is a quadratic function, which is expressed as[tex]D(t)= (t-10)^2.[/tex]This means that the diameter (D) of the lesion is dependent upon the time (t) that has passed since the lesion's onset. Specifically, the diameter of the lesion will increase as the time since onset increases.
The graph of this equation will be a parabola with its vertex at (10, 0). This is because, when t=10, the diameter of the lesion (D) will be zero. As t increases, the graph will move up and to the right, forming a parabola with a positive slope.
In addition to describing the diameter of the lesion as a function of time, the equation also allows us to calculate the diameter of the lesion for any given time. To do this, we can plug in the desired time value for t, and calculate the resulting diameter.
For example, if the medical researcher wants to determine the diameter of the lesion when t=15 days, they can plug in 15 for t, and calculate that the diameter of the lesion at that time is 25 cm. This can be found by plugging in 15 for t and calculating [tex]D(15)=(15-10)^2[/tex]=25 cm.
In conclusion, the equation[tex]D(t)= (t-10)^2.[/tex]is a quadratic function that describes the diameter of a lesion in cm as a function of time (days). The graph of the equation is a parabola with its vertex at (10, 0), and it can also be used to calculate the diameter of the lesion for any given time.

The correlation coefficient between heights from the ground of two people on the opposite ends of a seesaw would depend on the weight of the people and their distance apart.

When the seesaw is in equilibrium, the height of the people will be related inversely proportional to their weight. If the weight of one person increases, the height of the other person would decrease and vice versa.

The correlation coefficient will be negative and can range from -1 to 0, with -1 being the highest correlation. The closer the correlation coefficient is to -1, the more closely related the heights of the two people will be. The correlation coefficient will be zero when the people are not in equilibrium.

This is because the height of the people is not related in any way when the seesaw is not in equilibrium. Therefore, the correlation coefficient between heights from the ground of two people on the opposite ends of a seesaw is negative and ranges from -1 to 0.

The need for capital by the Sport Bat Corporation will spread through the financial system as it interacts with banks, investors, and the broader financial markets.

When the Sport Bat Corporation needs to borrow $2 million to upgrade their equipment, they will likely seek a loan from a financial institution, such as a bank. The bank will evaluate the creditworthiness of the company and may require collateral or a personal guarantee before approving the loan.

Once the loan is approved, the bank will add the Sport Bat Corporation's loan to their portfolio of assets. The bank may choose to sell the loan to other investors, such as insurance companies or pension funds, to diversify their portfolio and manage risk.

These investors will then receive the interest payments on the loan as a source of income. The loan may be bundled together with other loans and sold as a package, called a securitization, to other investors in the financial markets, thus representing the spread of the loan throughout the financial system.

Triangle WXY is not a right triangle, so XY is not tangent to circle W.

Additional comments

The parity of the integer side lengths of a right triangle is always even. That is, there can be two odd side lengths, but never just one odd side length.

Side lengths 54 and 66 are even, while length 87 is odd. There is only one odd side length, so this triangle cannot be a right triangle.

A tangent always meets a radius at right angles, so XY is a tangent if and only if angle X is a right angle.

Answer:

15 Full orbits per day

Step-by-step explanation:

To work out the number of full orbits the ISS does in 1 day, we need to know how long it takes for the ISS to complete one orbit around the Earth.

We can use the information given to us to calculate the time it takes for the ISS to complete one orbit:

Distance traveled in one orbit = 42,600 kilometers

Speed of the ISS = 27,576 kilometers per hour

To calculate the time taken for one orbit:

Time taken = Distance traveled / Speed

Time taken = 42,600 kilometers / 27,576 kilometers per hour

Time taken = 1.54 hours (rounded to 2 decimal places)

So, the ISS takes approximately 1.54 hours to complete one orbit around the Earth.

Now, we can calculate the number of orbits the ISS does in one day:

Number of orbits per day = 24 hours / Time taken for one orbit

Number of orbits per day = 24 hours / 1.54 hours

Number of orbits per day = 15.58 (rounded to 2 decimal places)

Therefore, the ISS completes approximately 15 full orbits around the Earth in one day.
