Answer:

Answer: B.-1/2

Step-by-step explanation:

Answer:

9, -19

Step-by-step explanation:

Given that the distance between point J and point K on a number line is 14, and the coordinate of J is -5, there are two possible coordinates that could represent the location of K.

K can either be located to the right of J, or to the left of J. Either ways, distance between J and K will still equal 14.

To the right we would have K located at: -5 + 14 = 9

To the left we can also have K located at: -5 - 14 = -19

K can be located at either 9 or -19

The percent error in Rashida's measurement while measuring the length of the beam is 4.29%.

What is meant by percent error?

The percent error is the distinction between the estimated value and the actual value in relation to the actual value. Percent errors show the magnitude of our measurement errors during an analysis procedure. We are getting close to the accepted or original value when the percent mistakes are smaller. The relative error is multiplied by 100 to get the percent error.

Given,

  The actual length of beam = 17 and 1/2 feet = 17.5 feet

The measured length of beam = 16 and 3/4 feet = 16.75 feet

The formula to find the percent error is as follows:

Percent error = \(|\frac{Measured\ value - Actual\ value}{Actual\ value} | * 100\)

                   =  \(|\frac{16.75 - 17.5}{17.5} | * 100 =\) 0.75/17.5 * 100 = 4.29%

Therefore the percent error in Rashida's measurement while measuring the length of the beam is 4.29%.

Answer:

\(Speed = \frac{38}{3}km/hr\)

Step-by-step explanation:

Given

\(Distance = 3\frac{1}{6}km\)

\(Time = \frac{1}{4}hr\)

Required

Determine the average speed

Average speed is calculated as thus;

\(Speed = \frac{Distance}{Time}\)

\(Speed = 3\frac{1}{6}/\frac{1}{4}\)

\(Speed = 3\frac{1}{6} * \frac{4}{1}\)

Convert Mixed Fraction to Improper fraction

\(Speed = \frac{19}{6} * \frac{4}{1}\)

\(Speed = \frac{19 * 4}{6 * 1}\)

\(Speed = \frac{76}{6}\)

Divide both sides of the fraction by 2

\(Speed = \frac{38}{3}\)

Hence:

The speed is:

\(Speed = \frac{38}{3}km/hr\)

Answer:

38/3

Step-by-step explanation:

When two variables are inversely proportional we can represent them in the following manner:

Where "a" would be the constant of proportionality. In the case of our problem the y is inversely proportional to the square of "x", this means that the correct expression is:

We need to find the value of "a", to do that we will apply the ordered pair which was given to us (17,8).

There are many different ways tο define an equatiοn. The definitiοn οf an equatiοn in algebra is a mathematical declaratiοn that illustrates the equality οf twο mathematical expressiοns.

Given that the tοtal number οf bοοks that sοld in a week is 288.

The number οf chemistry textbοοks sοld was 72 less than the number οf histοry textbοοks sοld.

Assume that the number οf histοry textbοοks sοld was x.

The number οf chemistry textbοοks sοld was (x-72)

The tοtal number οf bοοks sοld was x + (x-72) = 2x - 72.

Accοrding tο the questiοn:

2x - 72 = 288

Add 72 frοm bοth sides:

2x - 72 + 72 = 288 + 72

2x = 360

Divide bοth sides by 2:

x = 360/2

x = 180

The number οf histοry textbοοks sοld was 180.

The number οf chemistry textbοοks sοld was (180-72) = 108.

Payment per hour: p = $9.75 (I will identify the payment per hour as "p").

He worls from 8:00 am until 3 pm from monday through thursday, this means that he works 7 hours on those days. But since he takes a half hour lunch break, we take half an hour from the 7 hours:

Each from monday trough thursday that he works, he does it for 6.5 hours.

Thus, the total amount of hours for this four days of the week is:

On Friday he works from 8:00 am to 4:00pm, that is 8 hours, as in the previus days, we substract half hour for his break:

So the total amount of hours that he works in the week is the sum of the 26 hours that he works from monday through thursday, plus the 7.5 hours that he works on friday:

It will take a minimum of 10 clock hours (not driving hours) for the truck driver to travel 450 miles from Charlotte, NC to Pittsburgh, PA.

The current Hours of Service (HOS) rules for truck drivers stipulate that a truck driver cannot drive for more than 11 hours after 10 consecutive hours off duty.

Additionally, the driver is not allowed to drive beyond 14 hours after coming on duty.

The driver's shift includes both driving and non-driving time.

Therefore, it is necessary to consider the total amount of time spent on the job.

The truck driver will have to stop for rest breaks, refueling, or other reasons during the 450-mile journey to Pittsburgh, Pennsylvania. The driver is required to take a 30-minute break after eight hours of driving.

Therefore, the minimum number of clock hours (not driving hours) it will take the truck driver to travel the 450-mile distance from Charlotte, NC to Pittsburgh, PA is calculated as follows:

Time for the trip = (Distance ÷ Average Speed) + Breaks

Time for the trip = (450 ÷ 50) + (30 ÷ 60) × 2

Time for the trip = 9 + 1

Time for the trip = 10 clock hours

Therefore, it will take a minimum of 10 clock hours (not driving hours) for the truck driver to travel 450 miles from Charlotte, NC to Pittsburgh, PA.

Given information:

Mean time between calls to the center (ta) = 6 minutes

Standard deviation of time between calls (∂a) = 4 minutes

The statement cross-tabulation with two variables is known as twice-tabulation is false because there is no such term as "twice-tabulation" in the context of statistical analysis.

Cross-tabulation, also known as contingency table analysis, involves the analysis of categorical variables by creating a table that shows the frequency or distribution of one variable based on the levels of another variable.

It allows for the examination of the relationship between two variables, highlighting any associations or patterns that may exist. Each cell in the cross-tabulation table represents the count or proportion of observations that fall into specific combinations of categories from the two variables.

The term "twice-tabulation" does not exist in statistical literature and is not commonly used to refer to cross-tabulation with two variables. The correct term to describe this statistical technique is simply cross-tabulation or contingency table analysis.

Answer:

  y = (x -1)² -3

Step-by-step explanation:

A quadratic with a vertex at (h, k) will have an equation of the form ...

 y = a(x -h)² +k

You have (h, k) = (1, -3), and a vertical scale factor* of 1. So, the equation of the graphed curve is ...

  y = (x -1)² -3

_____

* One way to determine the value of "a" in the form shown is to look at the vertical difference between the vertex and the points 1 unit right or left of the vertex. Here, those points are 1 unit above the vertex, so the vertical scale factor "a" is 1.

The solution to the differential equation dy/dt = y^2(1 - t), with the initial condition y = 2 when t = 1, is: y = -1 / (t - (t^2)/2 - 3/2)

To find the solution to the differential equation dy/dt = y^2(1 - t) with the initial condition y = 2 when t = 1, we can use separation of variables and integrate.

First, let's separate the variables by moving all the terms involving y to one side and all the terms involving t to the other side:  dy/y^2 = (1 - t) dt

Now, we integrate both sides of the equation: ∫(dy/y^2) = ∫(1 - t) dt

Integrating the left side:-1/y = t - (t^2)/2 + C1

Next, we solve for y: y = -1 / (t - (t^2)/2 + C1)

Now, we can use the initial condition y = 2 when t = 1 to find the value of the constant of integration C1. Substituting these values into the equation, we have:

2 = -1 / (1 - (1^2)/2 + C1)

2 = -1 / (1 - 1/2 + C1)

2 = -1 / (1/2 + C1)

Multiplying both sides by (1/2 + C1):

2(1/2 + C1) = -1

1 + 2C1 = -1

2C1 = -3

C1 = -3/2

Now, we substitute the value of C1 back into the equation for y:

y = -1 / (t - (t^2)/2 - 3/2)
