Which are irrational numbers?

A car travels along the x-axis with increasing speed. Among the given graphs. the graph given in (a) most closely represents the motion of the car.

The slope of graphs (b) and (e) remains constant.

Here, the distance increases with time.

Graph (c) shows decreasing the velocity of the vehicle.

In graph (d) the velocity of the vehicle increases and then slows down.

In graph (a), speed is increased which means that as time passes the slope of the graph becomes steeper. here, the slope of the graph increases with time.

Hence, the speed of the car increases.

Therefore, the correct representation of the motion of the car is the graph (a).

Answer:

3/4

Step-by-step explanation:

First way:

We can find a common denominator for the fractions and then add the fractions:

½ + ¼ = (2/4) + (1/4)

= (2 + 1)/4

= 3/4

Second way:

We can convert the fractions to decimals and then add the decimals:

½ + ¼ = 0.5 + 0.25

= 0.75

In both methods, the result is 3/4 or 0.75.

The general solution to the given system of equations  dx/dt = 4x − y,  dy/dt = 16x − 4y is y = 4x + C

In this question we need to find the general solution of the given system. dx/dt = 4x − y              ............(1)

dy/dt = 16x − 4y           .............(2)

Divide equation (2) by equation (1),

(dy/dt)/(dx/dt) = 16x − 4y /  4x − y

(dy/dt)/(dx/dt) = 4(4x − y) / (4x − y)

(dy/dt)/(dx/dt) = 4

(dy/dt)* (dt/dx) = 4

dy/dx = 4

dy = 4 * dx

Now integrate both sides of above expression.

∫dy = ∫4 * dx

y = 4x + C

Therefore, the general solution is y = 4x + C

Answer:

full answer part(A,B,C)

Part A: An experiment would be the most appropriate design for investigating the effectiveness of a new formula of fertilizer.

The reason for this is that an experiment allows for the manipulation of one or more variables in order to study their effects on a particular outcome. In this case, the orchard owner could manipulate the use of the new formula of fertilizer and compare the results to the use of the current popular brand. This would allow for a more controlled and systematic investigation of the effects of the new formula on fruit production, as compared to other designs such as observational studies or surveys, which do not involve manipulation of variables.

Part B: To implement the experiment, the orchard owner could divide the orchard into two sections, with one section receiving the new formula of fertilizer and the other section receiving the current popular brand. The orchard owner could then measure the fruit production in both sections over a period of time, taking into account factors such as the type of fruit being grown, the age of the trees, and the weather conditions during the study period. It would also be important to ensure that the two sections are as similar as possible in terms of the type of soil, the amount of sunlight they receive, and other relevant factors that could affect fruit production.

Part C: One benefit of this design is that it allows for a more precise and accurate assessment of the effectiveness of the new formula of fertilizer, as compared to other designs such as observational studies or surveys. By manipulating the use of the fertilizers and controlling for other variables, the orchard owner can be more confident that any differences in fruit production are due to the use of the new formula, rather than other factors that might confound the results. This can help the orchard owner make more informed decisions about whether to adopt the new formula for use on their orchard.

The value does 50% of the data lie above is 50.5 and is called the median.

The median is the value that's exactly in the middle of a dataset when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values.

Given that, The box plot shows the times for sprinters on a track team. A horizontal number line starting at 40 with tick marks every one unit up to 59. The values of 44, 48, 50.5, 53, and 56 are all marked by the box plot.

Data we get from the graph is

Minimum (min) = 44

Lower 1 (Q1) = 48

Median (med) = 50.5

Upper 3 (Q3) = 53

Maximum (max) = 56

The median is considered the second quartile (Q2).

The median cuts the data set in half. Half of the answers lie below the median and half lie above the median.

In order to display the distribution of grades (a, b, c, d, f) in a course, it would be correct to use a bar chart.

To create a bar chart to display the distribution of grades in a course, you would first need to gather the data on the number of students who received each grade. Once you have gathered this data, you can use a computer software tool or graph paper and a pencil to create the bar chart.

When creating the chart, you would label the x-axis with the different grades (a, b, c, d, f) and the y-axis with the number of students. Then, you would draw a bar for each grade, with the height of the bar representing the number of students who received that grade. You can also add a legend to the chart to provide more information about the data, such as the percentage of students who received each grade.

Answer:

6 centimeters is equal to 0.07 yards.

Step-by-step explanation:

To convert 6 centimeters into yards, we need to first convert the distance from centimeters to meters by dividing the distance in centimeters by 100:

Distance in meters = Distance in centimeters / 100

Distance in meters = 6 cm / 100

Distance in meters = 0.06 m

Next, we can convert the distance from meters to yards by dividing the distance in meters by 0.9144, which is the number of meters in a yard:

Distance in yards = Distance in meters / Meters per yard

Distance in yards = 0.06 m / 0.9144 m/yard

Distance in yards = 0.0654 yards

Rounded to the nearest hundredth, 6 centimeters is equal to 0.07 yards.

The probability that the proportion surviving for at least five years will exceed 80% is 0.00084.

It is given to us that -

65% of the total dialysis patients can survive for at least 5 years

A simple random sample consists of 100 new dialysis patients

We have to find out the probability that the proportion surviving for at least five years will exceed 80%.

From the given information, we have -

Probability, p = 65% = 0.65

=> Population mean, μ = 0.65

Number of patients in the sample, n = 100

The raw data, x = 80% = 0.80

Now, we know the standard deviation of a given sample can be calculated as -

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

=> σ = [tex]\sqrt{\frac{0.65(1-0.65)}{100} }[/tex]

=> σ = [tex]\sqrt{\frac{0.2275}{100} }[/tex]

=> σ = 0.04770 ----- (1)

We also know that the z-score can be calculated by the formula -

z = (x-μ)/σ

Substituting all the values in the above formula for z-score, we have -

z = (x-μ)/σ

=> z = (0.80-0.65)/0.04770

=> z = 3.14

From the normal distribution table, we can find out the corresponding area for the value of z = 3.14 which is equal to 0.99916.

For a value of the raw data, x to be more than 80%, the area to the right of normal distribution table for z = 3.14 is required.

=> P(x>80%) = 1-0.99916

=> P(x>80%) = 0.00084

Therefore, the probability that the proportion surviving for at least five years will exceed 80% is 0.00084.

The speed of the current and his paddling speed in still water will be 5.33 miles per hour and 1.33 miles per hour, respectively.

Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.

We know that the speed formula

Speed = Distance/Time

Let 'x' be the paddling speed in still water and 'y' be the current of water. Then the equations are given as,

x - y = 10 / 2.5

x - y = 4                  ...1

x + y = 10 / 1.5

x + y = 6.667          ...2

Add both equations, then we have

x + x = 4 + 6.667

x = 5.33 miles per hour
