What fraction goes in the box to make it correct?
4/11×_=1​

Answer:

x - 6 ≤ 9

Step-by-step explanation:

using the keywords 'less than', 'a number', and 'atmost' we can identify the problem.

Solution

For this case we can begin dividing both sides by 3500 and we got:

then we can take square root in both sides and we got:

And finally we can subtract 1 in both sides and we got:

and if we multiply by 100 we got:

r= 6.797 and rounded the answer would be:

The correct option is D. the number of sweatshirts for which cost and income are equal.

Any equation that contains only one element which squares the variable and none that raises it to a higher power.

The general form form of quadratic equation is-

ax² + bx + c = 0

According to the question;

Use the substitute method to get the quantity of sweatshirts in which cost and earnings are equal.

Step 1: Write the following system of equations as the first step.

\(\begin{aligned}&y=35 x \\&y=-0.05(x-400)^{2}+9492\end{aligned}\)

Step 2: Replace the value of "y" in the equation (2).

\(35 x=-0.05(x-400)^{2}+9492\)

Step 3: Make the equation above simpler.

\(35 x=-0.05 x^{2}-8000+40 x+9492\)

Step 4: Write the preceding equation in generalised quadratic form.

\(0.05 x^{2}-5 x-1492=0\)

The processes above lead to the conclusion that option D provides the proper statement.

Answer: Perimeter- 88m  Area- 207sqm

Step-by-step explanation: To find the perimeter, you have to sort of split the shape into simple boxes. To find the line at the bottom, you have to add 18+11 because you can see that they match the line in the bottom. 18+11=29. You then have to find the P of the left. With the same method, you do 6+9, which equals 15. You add all of the sides together to get 88m. To find Area, you split the boxes into 2 smaller boxes. you then do 18x6 to get 108 for the top box. And 11x9 which equals 99. You add them together to get the area, 207! Hope that makes sense!!!

I would like to construct a 95% confidence interval with a 4% margin of error. We don't have an estimate for the percentage, so we use a conservative estimate.

This is the minimum sample size, so we need to round up to 601. The larger the sample, the more confident the responses truly represent the population.

This shows that for a given confidence level, the confidence interval gets smaller as the sample size increases. At least 1450 samples from each group are required.

3/10

Step-by-step explanation:

if you make 1/2 into 5/10 and 4/5 into 8/10 than 8/10 is 3/10 more than 5/10

Hence proved that 3 can divides (4n + 5) for all natural numbers n.

To show that 3 divides (4n + 5) for all natural numbers n, we need to show that there exists some integer k such that:

4n + 5 = 3k

We can rearrange this equation as:

4n = 3k - 5

Since 3k - 5 is an odd number (the difference of an odd multiple of 3 and an odd number), 4n must be an even number. This means that n is an even number, since the product of an even number and an odd number is always even.

We can then write n as:

n = 2m

Substituting this into the original equation, we get:

4(2m) + 5 = 8m + 5 = 3(2m + 1)

So we can take k = 8m + 5/3 as an integer solution for all natural numbers n.

Let us compare 4/5 and 5/8.

To compare the numbers, we have to get the lowest common multiple (LCM). We can derive the LCM by multiplying the denominators which are 5 and 8. 5×8 = 40

LCM = 40.

Converting 4/5 and 5/8 to fractions with a denominator of 40:

4/5 = 32/40

5/8 = 25/40

The variance for the sum of the squared deviation scores is SS = 20 for a sample of n = 5 scores is 5.

The formula for the variance of a sample is:

\(s^2\) = SS / (n - 1)

where SS is the sum of squared deviation scores, n is the sample size, and \(s^2\) is the variance.

In this case, SS = 20 and n = 5, so we can substitute these values into the formula:

\(s^2\) = 20 / (5 - 1)

\(s^2\) = 5

The shape of the sampling distribution is attached below

What is standard deviation?

The standard deviation is a statistic that expresses how much variation or dispersion there is in a set of values. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the set mean.

The mean of the sampling distribution of the sample means is the mean of the population from which the scores were sampled.

The standard error of the mean is the standard deviation of the sampling distribution of the sample mean.

A Z-score indicates the number of standard deviations an element is deviated from the mean.

Using Central limit theorem,

If (n >30) is sufficiently large then the sampling distribution of sample mean follows a normal distribution with mean µx = µ

and standard error

σx = σ / √n

The formula for mean of the sample mean is,

µx = µ

The formula for standard deviation of the sample mean is,

σx = σ / √n

µ = 10.05

σ = 3

n = 64

∴The  value or mean of the sample mean is,

µx = µ

     = 10.05

The standard deviation of the sample mean is,

σx = σ / √n

If the target behavior is recorded whenever it occurs at any point within the scoring interval, the measurement procedure used is called continuous recording or event recording. This method involves observing and recording each instance of the behavior without considering its duration or intensity.

Continuous recording is typically used when the target behavior is discrete and occurs relatively infrequently or has a short duration. With this measurement procedure, each occurrence of the behavior is recorded as a separate event, regardless of when it starts or ends within the scoring interval. Examples of behaviors that can be measured using continuous recording include vocalizations, hand clapping, or instances of aggression.

Continuous recording provides a comprehensive account of the frequency or rate at which the behavior occurs, allowing for a detailed analysis of its occurrence patterns. This method is particularly useful when a precise count of behavior instances is needed and when the duration or intensity of the behavior is not a focus of measurement.

The equation of the line with slope m and y-intercept b is given by:

In this case the slope is 5 and the y-intercept is -2; then we have that the equation of the line is:

Now that we have the equation of the line we can use it to find points on the line, we do that by given values to x (whichever values we want) and use the equation to determine its corresponding y value.

If x=0, then we have:

Hence, the line passes through the point (0,-2).

If x=1, then we have:

Hence, the line passes through the point (1,3).

Now that we have two points on the line we graph them on the plane:

To estimate the size of a population of rabbits living in a large urban park, the best method to use is the mark and recapture method.

The mark and recapture method is a technique used to estimate the size of a population by capturing, marking, and releasing a sample of individuals and then recapturing a second sample later.

This method is based on the assumption that the proportion of marked individuals in the second sample will be equal to the proportion of marked individuals in the first sample.

To use the mark and recapture method to estimate the population size of rabbits in a large urban park, you would need to follow these steps:

Capture a sample of rabbits and mark them in a non-invasive way, such as using ear tags, tattoos, or fur dye.

Release the marked rabbits back into the park.

Wait for a period of time to allow the marked rabbits to mix back into the population.

Capture a second sample of rabbits from the park.

Count the number of marked and unmarked rabbits in the second sample.

Use the following formula to estimate the population size:

N = (M x n) / R

Where:

N is the estimated population

is the number of individuals in the first sample

n is the number of individuals in the second sample

R is the number of marked individuals recaptured in the second sample

The slope of the tangent line to the polar curve r = 2 - sin(θ) at the point specified by θ = π/3 is -1/2.

To find the slope of the tangent line to the polar curve r = 2 - sin(θ) at the point specified by θ = π/3, we need to first find the derivative of r with respect to θ, and then evaluate it at θ = π/3.

Differentiating both sides of the polar equation with respect to θ, we get:

dr/dθ = d/dθ(2 - sinθ)

dr/dθ = -cosθ

So, the derivative of r with respect to θ is -cosθ.

Evaluating this derivative at θ = π/3, we get:

dr/dθ|θ=π/3 = -cos(π/3) = -1/2

Therefore, the slope of the tangent line to the polar curve r = 2 - sin(θ) at the point specified by θ = π/3 is -1/2.
