The table shows the volume of water in cubic meters, V, in a tank after water has been pumped out after water has been pumpee out for a certain number of minutes. Which ewuation could represent the volume of water in cubif meters after T minutes of water being pumped out
​

Answer: 9 yards

Step-by-step explanation:

Given

The maple tree is 16 yards tall and its shadow is 12 yards tall

Suppose the angle made by the maple tree is x

\(\Rightarrow \cos x=\dfrac{12}{16}\)

For the tower also, the angle made by the tower and its shadow is x

Suppose the length of the shadow is y

\(\Rightarrow \cos x=\dfrac{y}{12}\)

Substitute the value of \(\cos x\)

\(\Rightarrow \dfrac{y}{12}=\dfrac{12}{16}\\\\\Rightarrow y=9\ \text{yards}\)

the marginal distribution fₓ.₃(2,3) of x and z is approximately 0.0333 for y=1 and 0.2444 for y=2.

What is Marginal distribution?

Marginal distribution refers to the probability distribution of a subset of variables in a joint probability distribution. It is obtained by summing or integrating the joint probability distribution over the remaining variables to obtain the probabilities or probability densities of the subset of interest.

To find the marginal distribution fₓ.₃(2,3) of random variables x and z, we need to sum up the joint distribution f(x,y,z) over all possible values of y.

Given the joint distribution f(x,y,z) = (xy²z) / 180, we can calculate the marginal distribution as follows:

fₓ.₃(2,3) = Σ f(x,y,z) over all y values

Let's calculate the values for y=1 and y=2:

For y=1:

fₓ.₃(2,3) = f(2,1,3) + f(2,1,2) + f(2,1,1)

= (2 * 1² * 3) / 180 + (2 * 1² * 2) / 180 + (2 * 1² * 1) / 180

= 6 / 180 + 4 / 180 + 2 / 180

= 0.0333

For y=2:

fₓ.₃(2,3) = f(2,2,3) + f(2,2,2) + f(2,2,1)

= (2 * 2² * 3) / 180 + (2 * 2² * 2) / 180 + (2 * 2² * 1) / 180

= 24 / 180 + 16 / 180 + 8 / 180

= 0.2444

So, the marginal distribution fₓ.₃(2,3) of x and z is approximately 0.0333 for y=1 and 0.2444 for y=2.

The percentage of animal wasted is the number of animal wasted over 100

85.7%  of the wild caught animals are wasted

From the question, we have:

Animals caught = 6 pounds

Salmon = 1 pound

The total weight in the system is:

Total = 6 pounds + 1 pound

So, we have:

Total = 7 pounds

The percent of wild caught animals wasted is then calculated as:

\(\%Wasted = \frac{6}{7} * 100\%\)

Simplify

\(\%Wasted = 85.7\%\)

Hence, 85.7%  of the wild caught animals are wasted

10 cm is the answer because 30÷3 angles

this aint the answer but this is to help u in class when u cant use this app

Step-by-step explanation:

id recommend desmos scientific calc. you put the #'s in ex: 5/2 = 2.5 and it gives u the exact answer so u can put them in order easier also , use a lined paper sideways and put the numbers in the spaces to line it out iyk what i mean by that so you can number it from least to greatest easier !!! if ur confused ill try amd help u understand it morw but thats just how it helped me get how to do it

The blanks in each statement about the line segment should be completed as shown below.

Since we know U is the midpoint, we can say TU=8x + 11 substituting in our values for each we get:

8x + 11 = 12x - 1

Solve for x

We now want to solve for x.

−4x+11=−1

−4x = -12

x= 3

Solve for TU, UV, and TV

This is just the first part of our question. Now we need to find TU, UV, and TV. Lets start with TU and UV.

TU=8x+11 We know that x=3 so let’s substitute that in.

TU=8(3)+11

TU= 35

We will do the same for UV. From our knowledge of midpoint, we know that TU should equal UV, however let’s do the math just to confirm.

UV=12x−1 We know that x=3 so let’s substitute that in.

UV=12(3)−1

UV= 35

Based on the segment addition postulate, we have:

TU+UV=TV

35+35=TV

TV= 70

Find the detailed calculations below;

TU = UV

8x + 11 = 12x - 1

8x + 11 - 11 = 12x - 1 - 11

8x = 12x - 12

8x - 12x = 12x - 12 - 12x

-4x = -12

x = 3

By using the substitution method to substitute the value of x into the expression for TU, we have:

TU = 8x + 11

TU = 8(3) + 11

TU = 24 + 11

TU = 35

By applying the transitive property of equality, we have:

UV = TU and TU = 15, then UV = 35

By applying the segment addition postulate, we have:

TV = TU + UV

TV = 35 + 35

TV = 70

The solution to the system is 6 and 11.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it has no "equal to" sign.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" symbol and terms on both sides must always be present when writing an equation.

Given equation:

y=2x-1 .....(1)

y=x+5....(2)

Now solving equation 1 and 2, we get

2x -1 = x + 5

2x - x= 5 +1

x = 6

and, y= 2x-1

y= 2(6)-1

y= 12 -1

y= 11

Hence, the value of x is 6 and y is 11.

To find the distinct possibilities for the values in the diagonal going from the top left to the bottom right of a BINGO card, we need to consider the ranges of numbers that can appear in each column.

The first column can have any 5 numbers from the set 1-15. There are 15 numbers in this range, so there are "15 choose 5" possibilities for the numbers in the first column.

The second column can have any 5 numbers from the set 16-30. Again, there are 15 numbers in this range, so there are "15 choose 5" possibilities for the numbers in the second column.

The third column has a Wild square in the middle, so we need to skip it and consider the remaining 4 squares. The numbers in the third column can come from the set 31-45, which has 15 numbers. Therefore, there are "15 choose 4" possibilities for the numbers in the third column.

The fourth column can have any 5 numbers from the set 46-60, which has 15 numbers. So there are "15 choose 5" possibilities for the numbers in the fourth column.

The last column can have any 5 numbers from the set 61-75, which again has 15 numbers. So there are "15 choose 5" possibilities for the numbers in the last column.

To find the total number of distinct possibilities for the diagonal, we multiply the number of possibilities for each column together:

"15 choose 5" "15 choose 5"  "15 choose 4"  "15 choose 5"  "15 choose 5".

Evaluating this expression, we find:

(3003)  (3003)  (1365)  (3003)  (3003) = 13,601,464,112,541,695.

The number of hours Jackson worked washing cars is 8 hours and the number of hours he worked landscaping is 6 hours

The payment of car washing per hour = $10

The payment for landscaping = $12

Total number of hours worked = 14  hours

Number of hours worked in car washing = x

Number of hours worked in landscaping = y

Then the first equation will be

x + y = 14

x = 14 - y

Total amount he earned = $152

Next equation will be

10x + 12y = 152
Here we have to use substitution method

10(14-y) + 12y = 152

140 - 10y +12y = 152

140 + 2y = 152

2y = 152 - 140

2y = 12

y = 12/2

y = 6 hours

Then

x = 14 - y

x = 14 -6

x = 8  hours

The given statement "For any sampled population, the population of all sample means is approximately normally distributed" is true. This is a result of the Central Limit Theorem, which states that when sample sizes are large enough, the means of all samples will be approximately normally distributed.

A sample is a smaller portion of the population that has been taken to draw conclusions about the characteristics of the population as a whole. The sample needs to be representative of the population for the data analysis to be valid.

A sample mean is a statistical analysis in which the sum of all data points in a sample is divided by the number of observations. It gives an idea of the average value of the data points in the sample population.

For any sampled population, the population of all sample means is approximately normally distributed. The central limit theorem states that when the sample size is sufficiently large, the distribution of the sample means will be approximately normal, regardless of the underlying distribution of the population.

The central limit theorem is an important concept in inferential statistics because it provides a theoretical foundation for the use of statistical inference methods to draw conclusions about population parameters based on sample statistics.

The lowest measurement scale the researcher could use to measure the differences in consumer feelings about the perceived reliability of the products is the ordinal scale.

In order to compare and rank consumer feelings about the perceived reliability of different products, the researcher needs a measurement scale that allows for a relative ordering of the responses. The ordinal scale is the lowest level of measurement that provides this capability.

An ordinal scale assigns numbers or labels to observations in a way that reflects their relative position or ranking.

It allows for comparisons of the responses in terms of greater or lesser, but it does not provide information about the magnitude of the differences between the rankings. In other words, it indicates the order of preference or strength of feeling but does not quantify the exact differences.

Using an ordinal scale, the researcher can ask consumers to rate the products on a scale such as "strongly disagree," "disagree," "neutral," "agree," and "strongly agree" in terms of their perceived reliability. Based on the responses, the researcher can determine the relative strength of feelings about each product's reliability by comparing the rankings.

While the ordinal scale provides valuable insights into the relative ordering of consumer preferences, it does not allow for precise measurements or calculations of mean differences between products. For more detailed analysis, higher-level measurement scales such as interval or ratio scales would be required.

Based on effect size conventions, d = 0.60 is considered a moderate effect size. It is a standardized measure that quantifies the magnitude of the difference or relationship between two groups or variables.

It provides a standardized way to compare the strength of effects across different studies or contexts. Effect size conventions vary across disciplines and research areas, but a commonly used benchmark is Cohen's d. In this convention, an effect size of d = 0.20 is considered small, d = 0.50 is considered medium or moderate, and d = 0.80 is considered large.

Therefore, with a value of d = 0.60, the effect size is considered moderate according to this convention. It indicates a meaningful and noticeable difference or relationship between the groups or variables being studied, but not as strong as a large effect size would suggest.

When procedures are mandated by third party payers, the modifier -32 (mandated services) is used. This modifier is used to indicate that a service or procedure is mandated by a third party payer, such as Medicare or Medicaid.

It is used to ensure that the service or procedure is reimbursed appropriately and to avoid denials. The use of the -32 modifier is important to accurately reflect the requirements of the payer and to avoid any potential billing or coding errors. It is important to check with the specific payer to determine if the use of this modifier is required for a particular service or procedure.

When procedures are "mandated" by third-party payers, you would use the modifier -32. This modifier indicates that a service or procedure is being performed due to specific requirements from a third-party payer. It helps to provide the necessary information for reimbursement and ensures that the claim is processed correctly by the payer. Remember to attach the modifier -32 to the appropriate procedure code on the claim form when submitting it to the third-party payer.
