Answer: C= -2

Step-by-step explanation:

Answer:

C. -2

Step-by-step explanation:

5x + 2(x − 4) = 5x + x − 10

Subtract 5 from both sides,

5x + 2(x - 4) - 5x = 5x + x - 10 - 5x

Simplify,

2(x - 4) = x - 10

Distribute,

2x - 8 = x - 10

Add 8 to both sides,

2x - 8 + 8 = x - 10 + 8

Simplify,

2x = x - 2

Subtract x from both sides,

2x - x = x - 2 - x

Simplify,

x = -2

The probability of seeing exactly 5 hearts out of 10 cards is\((13/52)^5 × (39/52)^5.\)

The probability of seeing exactly 5 hearts out of 10 cards can be calculated as follows: The total number of cards in a deck is 52. The number of hearts in a deck is 13. Since no card has been removed from the deck, the probability of seeing a heart is 13/52. The probability of seeing a non-heart is 39/52. Since we are looking at 10 cards, the probability of seeing exactly 5 hearts,

p(h)= 13/52

p(nh) = 39/52

hence, \((13/52)^5 × (39/52)^5\)

This means that the probability of seeing exactly 5 hearts out of 10 cards is \((13/52)^5 × (39/52)^5.\)

In a family with five girls and the probability of a boy being born is 1/2, the probability of the next child being a boy is still 1/2.

The previous births do not affect the probability of the next birth since each birth is an independent event.

The probability of an event occurring is determined by the ratio of the number of favorable outcomes to the total number of possible outcomes. In this case, the event of interest is the birth of a boy.

Since each birth is an independent event, the probability of having a boy on any given birth is always 1/2, regardless of the previous children born.

In the given scenario, the family already has five girls. This information is not relevant to the probability of the next child being a boy. The gender of the previous children does not affect the probability of the next child being a boy or a girl.

Therefore, the probability of the next child being a boy remains 1/2, as it is for any independent birth event.

When comparing two sample means, we can safely reject the null hypothesis if the calculated test statistic exceeds the critical value corresponding to the chosen significance level.

In hypothesis testing, when comparing two sample means, we typically perform a t-test or z-test depending on the characteristics of the data and assumptions. The null hypothesis assumes that there is no significant difference between the means of the two samples.

To determine whether we can reject the null hypothesis and conclude that there is a significant difference, we calculate a test statistic. The specific test statistic (t or z) depends on factors such as sample size and whether population parameters are known.

Next, we compare the calculated test statistic to the critical value. The critical value is determined based on the chosen significance level (commonly denoted as α). If the calculated test statistic exceeds the critical value, we reject the null hypothesis, indicating that there is evidence to support a significant difference between the two sample means.

The significance level determines the threshold for rejecting the null hypothesis and is typically set at 0.05 (5%) or lower, depending on the desired level of confidence.

Evaluating x = sin^(-1)(3/5) expression using a calculator or trigonometric table will give the value of x in degrees.

To find the value of x in the given triangle with base side labeled 4, vertical leg labeled 3, and hypotenuse labeled 5, we can use the trigonometric expression involving the sine function.

The sine function relates the ratio of the length of the vertical leg to the length of the hypotenuse in a right triangle. In this case, we have:

sin(x) = opposite/hypotenuse = 3/5

Therefore, the trigonometric expression that can be used to find the value of x is: sin(x) = 3/5

By taking the inverse sine (also known as arcsine or sin^(-1)) of both sides of the equation, we can solve for x:

x = sin^(-1)(3/5)

The statement, which shows the meaning of the taxi driver’s equation for the mileage and fee formula are statement B and E.

Linear equation or formula is the equation in which the highest power of the unknown variable is one.

Given information-

The formula equation for the mileage is,

\(3.00+0.50m=9.50\)

In the above formula the term m represents the number of miles traveled.

This formula written by the taxi driver shows the relation between the mileage and fee for his last customer. Using this expression the number of miles can be calculated as,

\(3.00+0.50m=9.50\)

Subtract with 3 both the sides,

\(0.50m=9.50-3.00\\0.50m=6.50\)

Divide by number 0.5 both the sides,

\(m=\dfrac{6.5}{0.5}\\m=13\)

Thus, his last costumer traveled 13 miles.

The 13 times 0.5 plus $3 is equal to the $9.50 which means nine dollars and fifty cents. Thus the option B is the correct option.

The number of miles traveled by customer is 13 miles. 13 miles of 50 cent  is equal to $6.5. If we add three dollars in it the result will be equal to the nine dollars and fifty cents. Thus the option E is correct.

Answer:

B = 31.6 degrees

Step-by-step explanation:

Here, we want to get the value of the angle marked B

From the diagram, AC faces B and that makes it its opposite side

BC is the adjacent side to B

The trigonometric identity we are to use here that connects the adjacent and the opposite is the tan

The tan is the ratio of the opposite to the adjacent side

Mathematically;

Tan B = AC/BC

Tan B = 14.1/22.9

Tan B = 0.6157

B = arc Tan 0.6157

Two rays with a common endpoint form an angle. An angle is defined as a geometric figure formed by two rays that share a common endpoint. In other words, an angle is formed when two rays emanating from a common point, and this common point is known as the vertex.

The rays are the sides of the angle, and the angle is measured in degrees. Angles have different measures, ranging from 0 degrees to 360 degrees. The two rays that make up an angle are also called the sides or arms of the angle. The angle is measured in degrees, and the size of the angle depends on the distance between the two sides of the angle that meet at the vertex.

In geometry, an angle can be named in different ways, depending on the context in which it is being used. Angles are essential in mathematics, physics, and other scientific fields, where they are used to measure the rotation of an object, determine the direction of an object, and in other applications involving rays and lines.

The value of the perpetuity today, with an annual interest rate of 8%, is $4,125.25.

To calculate the present value of a perpetuity, we can use the formula: Present Value = Cash Flow / Interest Rate.

In this case, the cash flow is $500 per year, and the interest rate is 8% (or 0.08 in decimal form). Plugging these values into the formula, we get: Present Value = $500 / 0.08 = $6,250.

However, this calculation gives us the present value of the perpetuity starting from today. Since the payments start 5 years from today, we need to discount the value by the present value of $1 received 5 years from today.

Using the formula for the present value of a single amount, we find that the present value of $1 received 5 years from today, with an 8% interest rate, is approximately 0.6806.

To calculate the present value of the perpetuity starting 5 years from today, we multiply the present value of $6,250 by the discount factor of 0.6806: Present Value = $6,250 * 0.6806 ≈ $4,250.25.

Therefore, the value of the perpetuity today, with an 8% annual interest rate and payments starting 5 years from today, is approximately $4,125.25.

The given differential equation is y(8x + y + 8)dx + (8x + 2y)dy = 0.

To solve this equation, we can use the integrating factor method. First, we identify the coefficients of dx and dy, which are y(8x + y + 8) and (8x + 2y), respectively. Then, we compare the equation with the standard form of a first-order linear differential equation, which is M(x, y)dx + N(x, y)dy = 0.

In our equation, M(x, y) = y(8x + y + 8) and N(x, y) = (8x + 2y). We can see that the coefficient of dy is not a function of x only, so we need to find an integrating factor.

The integrating factor (IF) can be found by multiplying both sides of the equation by the appropriate function. In this case, the integrating factor is \(e^{(f(N - M)/N dx).\)

By substituting the given values of M(x, y) and N(x, y) into the formula for the integrating factor, we can calculate the integrating factor and proceed with solving the differential equation.
