Answer:

The $19 car

Step-by-step explanation:

For a one day rental I'd say its pretty average to only be driving for about 160km which is about 100 miles. For those 160km you would only be paying $19. The combined total $38, which is still less than the $42.50 car. The only way this would somewhat equal out is if you drove 200km or 124 miles. That would make the total cost exactly $43. If Meghan plans on driving equal to or more than 200km then she should choose the $42.50 car. In my opinion the $19 should be enough for 1 day.

Answer:

angle A=angleB .…(समदिबाहु त्रिभुज भएर)

or, 34=34

angleA+angleB+angleC=180°

or, 34+34+4y=180

or, 68+4y=180

or, 4y=180-68

or, 4y=112

or, y=112÷4

Statistical tools serve the purpose of describing, making inferences, and drawing conclusions about numbers, making them essential in the assessment process. The correct answer is d.

Statistical tools play a crucial role in the assessment process by allowing us to describe, make inferences, and draw conclusions about numerical data. Statistical tools help in describing numbers by providing measures of central tendency (such as mean, median, and mode) and measures of variability (such as standard deviation and range). These descriptive statistics summarize the data and provide insights into its characteristics.

Statistical tools are used for making inferences about numbers. This involves using sample data to make predictions or generalizations about a larger population. Techniques such as hypothesis testing and confidence intervals enable us to draw conclusions about population parameters based on sample statistics.

Statistical tools are used to draw conclusions about numbers. Through data analysis, we can determine the relationships between variables, identify patterns or trends, and test the significance of findings. This allows us to make informed decisions or recommendations based on the evidence provided by the data.

Answer:

1.2

2.4√3÷3

3. x=45, y=15

Step-by-step explanation:

OK,

1. So the first part requires the Pythagoreanism formula which is: b²=a²+c²:

AC²=AB²+BC²====> AC²=(1)²+(√3)²===> AC²=4===> AC=2

2.The second part requires the formula of tan:

tan A=BC÷AB===> tan A=√3÷1===> tan A=√3

tan C=AB÷BC===> tan C=1÷√3===> tan C=√3/3

tan A+tan C=√3+√3/3===> 4√3÷3

3.And the last part requires the equation of angles:

A+B+C=180===>

x+y+x-y+90=180===> 2x=90===> x=45, y=15

Nonverbal instruments have been developed primarily in an attempt to d. assess issues that individuals cannot verbalize.

The answer is d. Nonverbal instruments have been developed primarily to assess issues that individuals cannot verbalize. These instruments are often used in psychology and educational assessments to measure skills and abilities in areas such as mathematics, language, and pre-reading skills, while controlling for the influences of language and culture. Nonverbal instruments can be particularly useful for individuals who struggle with verbal communication or have language barriers.

The exchange of information between people without the use of spoken or written language is referred to as nonverbal communication. Facial expressions, eye contact, gestures, posture, body movements, tone of voice, and even the use of time and space are all included in this broad category of behaviors.

A lot of information about a person's emotional state, intentions, attitudes, and personality traits can be communicated nonverbally. A person's posture and body language, for instance, might show whether they are feeling confident or uneasy, and their tone of voice and facial expressions can show whether they are happy, angry, or sad.

A crucial component of human contact is nonverbal communication since it can improve our ability to understand others, establish rapport, and communicate.

The regular octagon is the polygon perimeter is represented by graph.

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

Graph below shows the relationship between the side length(x) of a certain regular polygon and perimeter(y) of the polygon.

From the given graph, we have (0.5, 4) and (1.5, 12)

Slope(m)= (12-4)/(1.5-0.5)

m=8

Substitute m=8 and (x, y)=(0.5, 4) in y=mx+c, we get

4=8(0.5)+c

c=0

So, the equation is y=8x.

Therefore, the regular octagon is the polygon perimeter is represented by graph.

Answer:

2 vertically and -11 horizontally

Explanation:

the graph shifts 2 vertically and -11 horizontally

note: vertically is up ↑ and bottom ↓ , horizontal is right → and left ←

2 vertical and -11 horizontal.

Take one point of 1 (I chose the bottom left corner) and move up (vertical) two times, and left eleven times (horizontal).

The equation would be (x-11, y+2)

the answer is w=1 your welcomw

Answer:

w = 1

Step-by-step explanation:

2w + 4w + 3 = 8 - 5w + 6

combine like terms:

6x + 3 = 14 - 5w

add 5w to each side of the equation:

11w + 3 = 14

subtract 3 from each side:

11w = 11

divide both sides by 11:

w = 1

The average waiting time of passengers at a bus stop is calculated using the arrival process and the departure times of the buses.

Let's denote the rate of the Poisson process as λ, which represents the average number of passengers arriving per unit of time. The interarrival times between passengers will follow an exponential distribution with parameter λ.

Since the buses leave at regular intervals of T, we can consider each interval of T as a cycle. Within each cycle, the average waiting time for passengers will be T/2, as on average, a passenger would wait half of the cycle time before boarding the bus.

However, it's important to note that passengers arriving during the cycle time will have different waiting times. Some may arrive at the start of the cycle and wait for the entire duration of T, while others may arrive just before the bus departure time and have a waiting time close to zero.

To calculate the average waiting time, we need to consider the probability distribution of arrival times within the cycle and the expected waiting time within that interval. This calculation involves integrating the probability density function of the arrival process over the cycle time and averaging the waiting times accordingly.

The exact calculation will depend on the specific distribution of the arrival process, such as exponential or Poisson distribution, and the specific departure time pattern of the buses.

The second derivative of v with respect to t, denoted as d²v/dt², is equal to 4

The second derivative of v with respect to t, we will differentiate v twice.

v = 2t² + 7t + 11

First, let's find the first derivative of v with respect to t (dv/dt):

dv/dt = d/dt (2t² + 7t + 11)

Using the power rule of differentiation, we differentiate each term separately:

dv/dt = 2(2t) + 7(1) + 0

dv/dt = 4t + 7

Now, let's find the second derivative of v with respect to t (d²v/dt²):

d²v/dt² = d/dt (4t + 7)

Again, using the power rule of differentiation, we differentiate each term separately:

d²v/dt² = 4(1) + 0

d²v/dt² = 4

Therefore, the second derivative of v with respect to t, denoted as d²v/dt², is equal to 4.

The 99th percentile for the mean height of a random sample of 20 adult women is approximately 68.7 inches, which is 3.7 inches above the mean of 65 inches.

The 99th percentile for the mean height of a random sample of 20 adult women can be calculated using the normal distribution. The normal distribution is a bell-shaped curve that describes the probability of a given event occurring. In this case, the mean and standard deviation of the height of adult women is used to calculate the probability of the mean height of a sample of 20 adult women being a certain value. For the 99th percentile, this means that the probability of the mean of the sample of 20 adult women being equal to or less than the value of 68.7 inches is 99%. This value is 3.7 inches above the mean of 65 inches, which is the expected mean height of adult women.
