Answer:
23.54
Step-by-step explanation:
Distance Formula: \(\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)
We know the perimeter is the sum of all the side lengths of the triangle. Using the distance formula, we get \(\sqrt{(10-2)^2 + (9-5)^2}\) from X to Y, \(\sqrt{(6-10)^2+(1-9)^2}\) from Y to Z, and \(\sqrt{(6-2)^2 + (1-5)^2}\) from Z to X. This equals \(\sqrt{80}\)\(+\sqrt{80} + \sqrt{32}\), which equals approximately 23.54
I'm not sure what the previous triangles you calculated the area of were, or how this is different from those examples.

researchers can use the chi-square test to determine whether responses observed in a survey follow the expected pattern.
Answers
Researchers can use the chi-square test to determine whether responses observed in a survey follow the expected pattern is true.
The chi-square test is a statistical test that is commonly used to analyze categorical data and determine if there is a significant association or difference between observed and expected frequencies. It is particularly useful when analyzing data from surveys or experiments where responses are categorized into different groups.
The chi-square test evaluates the null hypothesis that there is no significant difference between the observed frequencies and the expected frequencies. By comparing the observed data to the expected data, the test calculates a chi-square statistic.
If the chi-square statistic is sufficiently large and exceeds a critical value at a given significance level, the null hypothesis is rejected, indicating that there is a significant deviation from the expected pattern.
Therefore, researchers can utilize the chi-square test to assess whether responses in a survey follow the expected pattern or if there are significant differences between the observed and expected frequencies. This test helps researchers draw conclusions about the relationship between variables and identify any patterns or associations within the survey data.

of water. Four minutes later, the tank contains 10 gallons of water.
a.
b.
C.
At what rate is the amount of water in the tank changing? Use a signed number (positive or
negative) in your answer.
How many more minutes will it take for the tank to drain completely?
How many minutes before Kiran arrived was the water tank completely full?
Answers
(a) The rate at which the amount of water is changing is -1/2.
(b) It will take 20 more minutes to drain the water completely.
(c) The tank was completely full 3 minutes before Kiran arrive.
What is Unit Rate?Unit rate is the amount of one quantity for a unit amount of the other quantity.
(a) Given that,
When Kiran first sees the tank, it contains 12 gallons of water. Four minutes later, the tank contains 10 gallons of water.
Rate at which the amount of water is changing = (10 - 12) / 4 = -2/4 = -1/2 gallons per minute.
(b) Time taken to drain 1/2 gallon = 1 minute
There are 10 gallons of water remaining in the tank.
Time taken to drain 10 gallons of water = (1 ÷ 1/2) × 10 = 20 minutes
It will take 20 more minutes to drain the water completely.
(c) When Kiran arrived, water tank has 12 gallons of water.
Total amount of water in the tank is 15 gallons.
Tank has lost 3 gallons of water before Kiran arrived.
Time taken to drain 3 gallons = (1 ÷ 1/2) × 3 = 6 minutes
So the tank was completely full 3 minutes before Kiran arrive.
Hence the rate is -1/2 gallons per minute.

In a given year, residents of a country spent approximately $52.9 billion on their pets. Of this amount, $17.3 billion was for veterinarian bills. What percent of the total was spent on veterinary cave?About ...% of the total was spent on veterinary care.
Answers
32.7 %
Explanation
we can easily solve this by using a rule of three
Step 1
Let x represents the percent of the total that was spent on veterinary
\(\begin{gathered} \text{ \$ 52.9 billions}\rightarrow100\text{ percent} \\ \text{ \$ 17.3 billons}\rightarrow x\text{ percent} \end{gathered}\)
the ratios are equal , so we have a proportion
\(\frac{52.9}{100}=\frac{17.3}{x}\)Step 2
solve the equation
\(\begin{gathered} \frac{52.9}{100}=\frac{17.3}{x} \\ \text{cross multiply} \\ 52.9x\cdot17.3\cdot100 \\ 52.9x=1730 \\ \text{divide both sides by 52.9} \\ \frac{52.9x}{52.9}=\frac{1730}{52.9}=32.7 \\ x=32.7 \\ \\ \end{gathered}\)so, the answer is
About 32.7% of the total was spent on veterinary care.

are each of the following true or false? (a) 3 n^2 10 n log n = o(n log n)
Answers
False. The expression \(3n^2 10n log n\) is not o(n log n) as the limit as n tends to infinity is not zero.
The expression \(3n^2 10n log n\) can be written as \(3n^2 10n log n = 3n^3 + 10n^2\) log n. Since \(3n^3\) is of a higher order than n log n, the expression 3n^2 10n log n is of a higher order than n log n, meaning 3n^2 10n log n ≠ o(n log n). To show this, we can calculate the limit of the expression as n tends to infinity: lim n→∞ (3n^3 + 10n^2 log n)/(n log n) = lim n→∞ (3n + 10 log n) = ∞. Since the limit is not zero, the expression 3n^2 10n log n is not o(n log n).The expression 3n^2 10n log n is not o(n log n) as the limit as n tends to infinity is not zero.

The zeros of the function are given by the equations:

It takes 36 caterpillars 15 hours to eat all the leaves on the bush in Violetta’s front yard. How many hours would it take 54 caterpillars to eat the same bush, assuming all the caterpillars eat at the same pace?
PLS PUT I HRS
NEED HELP PLEASE
Answers
Answer: 10 hours
Let's use the fact that the number of caterpillars eating the bush and the time it takes to eat the bush are inversely proportional to each other, since all the caterpillars eat at the same pace.
This means that if we increase the number of caterpillars, the time it takes to eat the bush will decrease, and vice versa.
Now, we can set up the proportion:
number of caterpillars * time to eat the bush = constant ( fixed number )
We know that 36 caterpillars can eat the bush in 15 hours, so the constant is:
36 * 15 = 540
To find how long it would take 54 caterpillars to eat the same bush, we can plug in the values into the formula and solve for the time:
54 * t = 540
t = 540 / 54
t = 10
It would take 54 caterpillars 10 hours to eat all the leaves on the bush in Violetta's front yard

1. Press the "2nd" button, followed by the "VARS" button.
2. Select "2: normalcdf(" from the list of options.
3. Enter the lower bound and upper bound for the z-score. To find the p-value for a specific z-score, you would typically use -∞ (negative infinity) as the lower bound and the z-score as the upper bound.
4. Enter the mean and standard deviation of the standard normal distribution. The mean for the standard normal distribution is always 0, and the standard deviation is always 1.
5. Press the "Enter" button to calculate the p-value.
The calculator will display the p-value, which represents the probability of observing a z-score as extreme as the one entered or more extreme.
Remember to consult the user manual or refer to the calculator's instructions for specific guidance on using functions and inputting values on your TI-84 Plus calculator.

Answers
Correct option is C. used to predict the dependent variable called the intervening variable.
What is the relation between a function and the dependent and independent variables?
A function has the following format: y = f(x).
In which each value of y is a function of one value of x, and thus, x is the independent variable and y is the dependent variable.
That is, the input of the function is the independent variable and the output is the dependent variable.
A function is a rule that assigns each value of the independent variable to exactly one value of the dependent variable.
In regression analysis, a function y = f(x) is generated, which predicts the output y according to the input variable x.

325 divided by 2.5 show your work
Answers
Answer:
130
Step-by-step explanation:
325 ÷ 2.5
= 130
325 divided by 2.5 is equal to 130
To divide 325 by 2.5, we can simplify the calculation by multiplying both the dividend and the divisor by 10 to eliminate the decimal point.
Thus, 325 divided by 2.5 is equivalent to (325 * 10) divided by (2.5 * 10), which becomes 3250 divided by 25.
Dividing 3250 by 25 gives us the quotient of 130.
Therefore, 325 divided by 2.5 is equal to 130. By multiplying both the dividend and divisor by 10, we effectively remove the decimal point and simplify the division process.
