Answer:

y = 15 , x = 6

Step-by-step explanation:

you can easily find y from first equation

Move y to the other side of the equation and reverse its sign

so (-11) changes to (+11) and now we have this equation

y = 15

now you must replace 15 instead of y in second equation ,then we have this equation

15 = 2x + 3

now we have to find x

move (+3) to other side of equation and reverse its sign

(+3) changes to (-3)

we have this equation now

15 - 3 = 2x

12 = 2x

x = 12 ÷ 2 = 6

The value of x is 10 if Leg= 8 and Leg=x-4.

This states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“.

In this scenario we were given

Leg= 8

Leg=x-4

Hypotenuse=x

Therefore : x² = 8² + (x-4)²

x² = 64 + x² - 8x + 16

x² -  x² = 80 - 8x

8x = 80

x = 80/8 = 10

Therefore hypotenuse is 10 and the length of the other side is (10-4) = 6.

Answer:

STo solve for m in the equation -319.45 = m, we can isolate the variable m by adding 319.45 to both sides of the equation:

-319.45 + 319.45 = m + 319.45

This simplifies to:

0 = m + 319.45

Finally, we can subtract 319.45 from both sides to solve for m:

0 - 319.45 = m + 319.45 - 319.45

-319.45 = m

Therefore, the value of m is -319.45.tep-by-step explanation:

Step-by-step explanation:

We have two shapes on a graph and the question is asking for the translation of rhombus QRST to rhombus Q'R'S'T.

Looking at the graph we can see that not only does the rhombus move backwards, but also downward, this indicates that our answers will be in a subtracting symbol.

So all we have to do is count the amount of spaces rhombus QRST went to get to rhombus Q'R'S'T

To solve this question, we find the sample mean, sample standard deviation, sample size, the number of degrees of freedom, the confidence interval and the required sample size. For each step, the procedures are explained and we find what is asked.

Doing this, we find that the sample mean is 347.3, the sample standard deviation is 467.4, the sample size is 10, the number of degrees of freedom is 9, the t-value for a 95% confidence interval is t = 2.2226, the margin of error for a 95% confidence interval for this sample is 328.5, the 95% CI is $18.8 < µ < $675.8 and the sample size needed in order to obtain a margin of error of no more than 100 is 94.

--------------------------------------

The sample mean is

Sum of all values divided by the number of values, thus:

\(\overline{x} = \frac{102 + 69 + 280 + 180 + 33 + 89 + 1643 + 205 + 177 + 695}{10} = 347.3\)

The sample mean is 347.3.

--------------------------------------

The sample standard deviation is

Square root of the sum of the difference squared between each value and the mean, divided by one less than the sample size. So

\(s = \sqrt{\frac{(102-347.3)^2 + (69-347.3)^2 + (280-347.3)^2 + (180-347.3)^2 + (33-347.3)^2 + (89-347.3)^2 + \cdots}{9}} = 467.4\)

The sample standard deviation is 467.4.

--------------------------------------

The sample size is

10 observations, thus the sample size is 10.

--------------------------------------

The degree of freedom for the Studentized version of the sample mean is

One less than the sample size, so 10 - 1 = 9.

The number of degrees of freedom is 9.

--------------------------------------

The point estimate for the mean of ALL US Overseas Loans and Grants is

The sample mean, which is 347.3.

The point estimate is 347.3.

--------------------------------------

The t-value for a 95% confidence interval is t

The t-value is found looking at the t table, with 9 degrees of freedom(y-axis) and a confidence level of \(1 - \frac{1 - 0.95}{2} = 0.975\). So we have T = 2.2226.

The t-value for a 95% confidence interval is t = 2.2226.

--------------------------------------

The Margin of error for a 95% confidence interval for this sample is

\(M = t\frac{s}{\sqrt{n}}\)

In which s is the standard deviation of the sample and n is the size of the sample.

For this question, \(s = 467.4, n = 10\), and thus:

\(M = 2.2226\frac{467.4}{\sqrt{10}}\)

\(M = 328.5\)

The margin of error for a 95% confidence interval for this sample is 328.5.

--------------------------------------

The 95 % confidence interval estimate of the mean of ALL US Overseas Loans and Grants is

The lower end of the interval is the sample mean subtracted by M. So it is 347.3 - 328.5 = 18.8

The upper end of the interval is the sample mean added to M. So it is 347.3 + 328.5 = 675.8

The 95 % confidence interval estimate of the mean of ALL US Overseas Loans and Grants is:

$18.8 < µ < $675.8.

--------------------------------------

The sample size is needed in order to obtain a margin of error of no more than 100 is

Here, we have to consider the sample standard deviation as the population standard deviation, and use the z-distribution. So

We have to find our  level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\(\alpha = \frac{1 - 0.95}{2} = 0.025\)

Now, we have to find z in the Z-table as such z has a p-value of .

That is z with a p-value of , so Z = 1.96.

Now, find the margin of error M as such

\(M = z\frac{\sigma}{\sqrt{n}}\)

In which \(\sigma\) is the standard deviation of the population and n is the size of the sample.

In this question, \(\sigma = 467.4\)

We have to find n for which M = 100. So

\(M = z\frac{\sigma}{\sqrt{n}}\)

\(100 = 1.96\frac{467.4}{\sqrt{n}}\)

\(100\sqrt{n} = 1.96*467.4\)

Dividing both sides by 100:

\(\sqrt{n} = 1.96*4.674\)

\((\sqrt{n})^2 = (1.96*4.674)^2\)

\(n = 83.92\)

The sample size needed in order to obtain a margin of error of no more than 100 is 94.

Part A: The probability of rolling a 5 is 1/6 or approximately 0.167. Part B: the probability of rolling an even number is 3/6 or 1/2 or 0.5.

Probability is a branch of mathematics concerned with measuring the likelihood or chance of an event occurring. It is defined as the ratio of the number of favorable outcomes to the total number of possible outcomes. Probability is expressed as a number between 0 and 1, where 0 means that the event will not occur and 1 means that the event will definitely occur. For example, if the probability of an event is 0.5, it means that the event has an equal chance of occurring or not occurring. Probability is used in various fields, such as science, engineering, finance, and statistics, to make predictions and make decisions based on uncertain events.

Part A:

The number cube has six faces, and each face has an equal chance of landing face-up. Therefore, the probability of rolling a 5 is 1/6 or approximately 0.167.

Part B:

The even numbers on a number cube are 2, 4, and 6. There are three even numbers out of a total of six possible outcomes. Therefore, the probability of rolling an even number is 3/6 or 1/2 or 0.5.

The value of the given integral \(\int^{\text{In}3/5}_{0}\frac{3e^{5t}}{(2e^{5t}+3)^2}dt\) is 2/75.

The given integral is \(\int^{\text{In}3/5}_{0}\frac{3e^{5t}}{(2e^{5t}+3)^2}dt\).

We have to evaluate the given integral.

The given integral is definite integral. To evaluate the given integral we firstly solve the integral then we put the value in the solved integral to find the value.

We solving the integral \(\int\frac{3e^{5t}}{(2e^{5t}+3)^2}dt\)

Let u = 2e^{5t}+3

Now differentiating

du/dt = 10e^{5t}

e^{5t}dt = du/10

\(\int\frac{3e^{5t}}{(2e^{5t}+3)^2}dt=\frac{3}{10}\int\frac{1}{u^2}dt\)

\(\int\frac{3e^{5t}}{(2e^{5t}+3)^2}dt=\frac{3}{10}\int{u^{-2}}dt\)

\(\int\frac{3e^{5t}}{(2e^{5t}+3)^2}dt\) = 3/10 [u^{-2+1}/(-2+1)]+C

\(\int\frac{3e^{5t}}{(2e^{5t}+3)^2}dt\) = 3/10 [u^{-1}/(-1)]+C

\(\int\frac{3e^{5t}}{(2e^{5t}+3)^2}dt\) = -3/10(1/u)+C

\(\int\frac{3e^{5t}}{(2e^{5t}+3)^2}dt\) = -3/10(1/2e^{5t}+3)+C

Now;

\(\int^{\text{In}3/5}_{0}\frac{3e^{5t}}{(2e^{5t}+3)^2}dt=-\frac{3}{10}\left[\frac{1}{2\cdot3+3}-\frac{1}{2+3}\right]\)

\(\int^{\text{In}3/5}_{0}\frac{3e^{5t}}{(2e^{5t}+3)^2}dt=-\frac{3}{10}\left[\frac{1}{6+3}-\frac{1}{2+3}\right]\)

\(\int^{\text{In}3/5}_{0}\frac{3e^{5t}}{(2e^{5t}+3)^2}dt\) = -3/10[1/9 - 1/5]

\(\int^{\text{In}3/5}_{0}\frac{3e^{5t}}{(2e^{5t}+3)^2}dt\) = -3/10[5-9/45]

Measures of location and dispersion are computed from grouped data rather than individual data values when dealing with large datasets or continuous variables that have been grouped into intervals.

This grouping is common in statistical analysis to simplify the data representation and make it more manageable.

Here are some scenarios when it is appropriate to compute measures from grouped data:

1. Large datasets: For datasets with a large number of individual data points, it becomes impractical to list and analyze each value individually. Grouping the data into intervals allows for a more concise representation.

2. Continuous variables: When dealing with continuous variables, it is often more natural to group the data into intervals, as there are infinitely many possible values between any two points. Grouping helps in summarizing the data without losing too much important information.

3. Histograms and frequency tables: Grouping data into intervals is essential for creating histograms and frequency tables. Histograms provide a visual representation of the data's distribution, and frequency tables display the number of data points falling within each interval.

4. Discretization: Sometimes, data might already be grouped due to discretization processes (e.g., rounding or classification).

When working with grouped data, specific formulas and methods need to be used to compute measures of location and dispersion. For example, for grouped data, the sample mean and variance are calculated using the midpoint of each interval, rather than individual data values.

However, it's worth noting that using individual data values is generally more accurate in capturing the variability and characteristics of the dataset. If the dataset is not too large, and there are no specific reasons to group the data, it is preferable to use individual values for a more detailed analysis.
