Solving the equation 4x + 7 = 9 will give value of x = 1/2

To solve we will use the equation

4x + 7 = 9

By subtracting 7 from both side we get

4x + 7 -7 = 9 -7

4x = 2

By diving 4 from both sides we get

4x/4 = 2/4

x = 1/2

To check we put the value of x in the equation we get

4(1/2) + 7 = 9

2 + 7  = 9

9 = 9

Hence the value of x is satisfying the equation

Therefore, the value of x is 1/2

As a "financial-advisor" for company, it is important to consider request of owner to change method of estimating "bad-debts" to a flat 3% of receivables, given the circumstances described.

(i) It is crucial to understand the reasons behind change in method of estimating bad debts.

In this case, the company is facing a "cash-crunch" and needs to borrow money from the bank, using accounts receivable as collateral.

The owner is aware that many of "accounts-receivable" are more than 90 days past-due, which results in net receivables equal to only 80% of total receivables,

It indicates that company is experiencing a higher level of delinquency in its accounts receivable, and the owner may be seeking a more conservative estimate of bad debts to reflect this situation.

(ii) A more prudent approach would be to conduct a thorough analysis of the company's accounts receivable, considering factors such as the aging of accounts, historical collection patterns, industry norms, economic conditions, and creditworthiness of customers.

This help in developing a more accurate and reliable estimate of bad debts that aligns with the company's specific circumstances.

(iii) it is important to communicate-effectively with owner and other relevant stakeholders, explaining reasons behind recommended method of estimating bad debts and the potential implications of using a flat percentage.

This can help in building transparency, trust, and confidence in the financial reporting process and decision-making of the company.

By z-test the test static is 1.25.

What is z-test?

It is a statistical test to determine whether two population means are different at the time when the variances are known and the sample size is large. Also it is a hypothesis test in which the z-statistic maintains a normal distribution.

A random sample of 100 people was taken. Eighty-five of the people in the sample favored Candidate A. We are interested in determining whether or not the proportion of the population in favor of Candidate A is significantly more than 80%.

So from the given information we have,

sample size (n)= 100

sample proportion ( p₁) = 0.85 [ 85 of the people in the sample favored  candidate A]

So, the null hypothesis ,

H₀ : p = 0.80

The alternative hypothesis ,

Hₐ : p > 0.80

Now the test static can be determined by the formula of z-test

[tex]z= \frac{p_{1} - p }{\sqrt{\frac{p(1-p)}{n} } }[/tex]

[tex]z= \frac{0.85 - 0.80 }{\sqrt{\frac{0.80(1-0.80)}{100} } }[/tex]

[tex]z= \frac{0.05}{\sqrt{\frac{0.16}{100} } }[/tex]

z = (0.05× 10)/0.4

z= 1.25

In mathematics, an inequality is a mathematical statement that describes a relationship between two quantities that are not necessarily equal. An inequality can express that one quantity is less than, less than or equal to, greater than, greater than or equal to, or not equal to another quantity.

Inequalities can be represented using various symbols. For example, the symbol < represents "less than," the symbol > represents "greater than," the symbol ≤ represents "less than or equal to," and the symbol ≥ represents "greater than or equal to." The symbol ≠ represents "not equal to."

Inequalities are also used in algebra to solve equations and to represent the solution set of an equation. In this context, an inequality can represent all the possible values of a variable that satisfy the equation. For example, the inequality x > 5 represents all the values of x that make the expression x - 5 positive.

We can write an inequality to represent the number of points, m, obtained by Machelle on her exam:

m > 100 - 27

Simplifying this expression, we get:

m > 73

The term that is not affected the standard error of an estimator is population size, from the provide data in options. So, option (c) is right one.

The standard error is a statistical term that used to measured the accuracy that a sample distribution represents a population by using standard deviation. The standard error(SE) is very similar to standard deviation of a distribution. Both are used to measure the spread of distribution. Higher the value SE, the more spread out your data is. In statistical way, standard error is also called standard error of mean, SEM, it represents the deviation of sample mean deviates from the actual mean of a population.

It is calculated simply by dividing the standard deviation by the square root of the sample size. That is [tex]SE = \frac{σ }{\sqrt{n}}[/tex]

where , n --> sample size

The value of x is 65. Please note that this solution is based on the assumption that the angles QRP and PSQ are supplementary. If this assumption doesn't hold, feel free to let me know.

We need to find the value of x in the equation ZQRP = (2x + 20)° given that ZPSQ = 30°. Since the question doesn't provide enough information about the relationship between angles QRP and PSQ, I'll assume that they are supplementary angles (angles that add up to 180°). This assumption is based on the possibility that the angles form a straight line or a linear pair.

If angles QRP and PSQ are supplementary, their sum is 180°:

(2x + 20)° + 30° = 180°

Now, we can solve for x:

2x + 50 = 180

Subtract 50 from both sides:

2x = 130

Divide by 2:

x = 65

To determine which points lie in the solution set of the system of inequalities x-y>-4, 2x-y<5, and 2y + x>1, we can graph the inequalities on a coordinate plane and look for the region that satisfies all three inequalities.

To graph the inequality x-y>-4, we can first graph the line x-y=-4 by plotting the points on the line:

x y

0 -4

-4 0

Then, we can shade the region above the line, since all points above the line will satisfy the inequality x-y>-4:

 |

-4 |    x

  |   /

  |  /  

  | /  

  |/

   -4   0

To graph the inequality 2x-y<5, we can first graph the line 2x-y=5 by plotting the points on the line:

x y

0 5

2.5 0

Then, we can shade the region below the line, since all points below the line will satisfy the inequality 2x-y<5:

 |

5 |     x

  |   / |

  |  /  |

  | /   |

  |/    |

 0 +----|--

To graph the inequality 2y + x>1, we can first graph the line 2y + x = 1 by plotting the points on the line:

x y

0 0.5

1 0

Then, we can shade the region above the line, since all points above the line will satisfy the inequality 2y + x>1:

 |

2 |     x

  |     |

 1|-----

  |   /  

  |  /

Step-by-step explanation:

-9u - v = -49i - 33j

To find -9u - v, you need to multiply the vector u by -9 and subtract the vector v from the result.

Given u = 5i + 4j and v = 4i - 3j, first multiply u by -9:

-9u = -9(5i + 4j) = -45i - 36j

Now, subtract the vector v from -9u:

-9u - v = (-45i - 36j) - (4i - 3j) = (-45i - 4i) + (-36j + 3j) = -49i - 33j

A circle with center Q and equilateral triangle NOP, where points N and O lie on the circle

What is a circle?

A circle is a two-dimensional shape with a perfectly round boundary that has no corners or edges. It is defined as the set of all points in a plane that are equidistant from a fixed point called the center. The distance from the center to any point on the boundary of the circle is called the radius.

The circumference of a circle is the distance around the boundary of the circle, and it is calculated as 2π times the radius. Circles are found in many natural and man-made objects, such as wheels, planets, and coins, and they have a wide range of applications in mathematics, science, and engineering.

To construct a circle with center Q and equilateral triangle NOP where points N and O lie on the circle, follow these steps:

Draw line segment PQ as the base of the equilateral triangle NOP.

Draw a perpendicular bisector of PQ, which intersects PQ at its midpoint, say M. This bisector will be the axis of symmetry of the equilateral triangle NOP.

With M as the center and MP (or MQ) as the radius, draw a circle that intersects PQ at two points, say X and Y.

Using Q as the center and QX (or QY) as the radius, draw two arcs that intersect the circle drawn in step 3 at two points, say N and O.

Draw the lines NQ and OQ to complete the equilateral triangle NOP.

Now, you have a circle with center Q and equilateral triangle NOP, where points N and O lie on the circle.

So, we would expect about 5 albino Galapagos tortoises to be born out of 500,000 Galapagos tortoises hatched, assuming that the theoretical probability holds true in practice.

Probability is a branch of mathematics that deals with the measurement and analysis of random events. It is the study of how likely an event is to occur, expressed as a number between 0 and 1, where 0 indicates an impossible event and 1 indicates a certain event. Probability is used in many areas of mathematics, science, and engineering, such as statistics, physics, finance, and computer science. It is a fundamental concept for understanding and predicting the behavior of random events and systems.

Here,

To find the expected number of albino Galapagos tortoises, we can use the formula:

Expected value = Probability of event * Total number of trials

In this case, the probability of an albino Galapagos tortoise being born is 0.001 or 0.001/100 = 0.00001 (as a decimal). The total number of trials is 500,000, since that is the number of Galapagos tortoises that hatched.

Let A be the event of taking the first job, and B be the event of taking the second job. Then, the probability of taking the first job is P(A) = 0.5, and the probability of taking the second job is P(B) = 0.4. The probability of taking both jobs is zero, since we cannot take both.

Therefore, the probability of taking either one job or the other job is:

P(A or B) = P(A) + P(B) - P(A and B)
