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

Convert 6 centimeters into yards. Round your answer to the nearest hundredth.
Answers
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.

Answers
The intervals in which both functions f(x) and g(x) are increasing are given as follows:
(-∞, -3) U (-1, ∞).
How to determine the behavior of the function?The behavior of a function is classified as either increasing, decreasing or constant, as follows:
Increasing: as x increases the function increases, that is, the graph moves up and right.Decreasing: as x increases the function decreases, that is, the graph moves down and right.Constant: as x increases the function remains constant, that is, the graph moves right while staying constant.From these bullet points and the functions given at the end of the answer, we have that the behavior of each function is given as follows:
Function f(x) is increasing over it's entire domain.Function g(x) is decreasing over the interval (-3,-1), and increasing over the remainder of the domain.Thus, both functions are increasing on the interval, (-∞, -3) U (-1, ∞), which is the first option.

find the general solution of the given system. dx dt = 4x − y dy dt = 16x − 4y
Answers
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

Jayla bought the ingredients to make chicken soup, and wanted to make a double batch, which would be 12 cups of soup.
A quick search told her that this was 173.3 cubic inches. she hoped the soup pot below would be big enough.
The soup pot is 8 inches tall with a radius of 3 inches.
We have to find the volume of the soup pot.
Since the cup is in the shape of cylinder.
So the volume of cylinder = πr^2h
from the question, r = 3 inches and h = 8 inches
π = 3.14
The volume of cylinder = πr^2h
The volume of cylinder = 3.14 * (3)^2*(8)

The quadratic equation has 2 non-real numbers as solutions.
How many solutions the quadratic equation has?Here we have the graph of a quadratic equation of the form:

And the solutions of the quadratic equation are the values of x such that:
0 = a*x^2 + b*x + c
To identify these values, we need to see the values of x such that the graph intercepts the x-axis. But here we can see that the graph never intercepts the x-axis.
Then the solutions are complex numbers, and because it is a quadratic, there are two.

Answers
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.
What is speed?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
Then the value of 'y' is given as,
x - y = 4
5.33 - y = 4

in a simple random sample of 100 new dialysis patients, what is the probability that the proportion surviving for at least five years will exceed 80%, rounded to 5 decimal places?
Answers
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.

Part C: Explain one benefit your design would provide. (3 points)
Please help!!!!!!!!! Will give brainliest for full explanation of all parts.
Answers
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.

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.
Thus, a bar chart would be the best to use for dispaying the distribution of grades.
