Let's assume the number of boys in Stephen's class is B. According to the given information, the number of girls in the class exceeds the number of boys by 8. Therefore, the number of girls would be B + 8.

The total number of pupils in the class is given as 36. We can write this as an equation:

B + (B + 8) = 36

Simplifying the equation, we have:

2B + 8 = 36

2B = 36 - 8

2B = 28

B = 28/2

B = 14

So, there are 14 boys in Stephen's class. Since the number of girls exceeds the number of boys by 8, the number of girls would be 14 + 8, which is equal to 22.

Therefore, there are 14 boys and 22 girls in Stephen's class.

The ANOVA method is very useful when conducting research involving multiple groups or populations, as it allows researchers to test for significant differences in the means of multiple populations in a single test.

Analysis of variance is an extremely popular approach for examining the significance of population variations. It's used to estimate the population variance of two or more groups by comparing the variance between the groups to the variance within them.

ANOVA (analysis of variance) is a statistical method for determining whether or not there is a significant difference between the means of two or more groups. The total sample size in the experiment is nT, and there are k populations. The mean square due to error is SSE/(k-1), while the mean square due to treatment is SSTR/k.

The F-statistic, which is used to test the null hypothesis that there is no difference between the means of the populations, is calculated by dividing the mean square due to treatment by the mean square due to error. If the F-statistic is high, it suggests that there is a significant difference between the means of the populations, and the null hypothesis should be rejected.

As a result, option C, or 3 mils, is the correct response.

A metric weight measurement unit. A gram is such thousandth of a kilogram, or about 30 times smaller than an ounce.

This issue can be resolved by converting from grams to mils using the conversion factor provided on the label.

1 mil = 500 mg

It is necessary to convert 1.5 grams to mils. To achieve this, you must cancel out all of the quantities in grams and use the conversion factor to derive the units in mils. The following equation can be created:

1.5 grams x (1 mil / 500 mg) = x mil

Where x represents the mils.

When the right hemisphere of the solution is simplified, we obtain:

1.5 grams x (1 mil / 500 mg) = 1.5 / 0.5 mil

1.5 / 0.5 = 3

The measurement of altitude BE is 4 unit.

As the average level of the sea's surface, sea level is used to measure altitude. A high altitude is defined as being significantly higher than sea level, such as Mount Everest. It is referred to as having a low altitude when something is closer to the ground, like a plane coming in to land.

As ABCD is rectangle

AD = BC = 12

ΔABC = ΔBCD

BE = FD

5² = 3²+BE²

AE = 3

BE = √(5²-3²)

BE = 4

Thus, The measurement of altitude BE is 4 unit.

Answer:

y = 3x + 2 because there are no value for x.

Step-by-step explanation:

Answer:

The length of the sides are 3 feet and 4 feet, respectively.

Step-by-step explanation:

Given the fact that triangle is a right triangle, it can be represented by Pythagorean Theorem:

\(r^{2} = x^{2}+y^{2}\)

Where:

\(r\) - Hypotenuse, measured in feet.

\(x\), \(y\) - Legs, measured in feet.

In addition, each leg can be determined as functions of hypotenuse:

\(x = r-2\,ft\)

\(y = r-1\,ft\)

Hence, the Pythagorean identity can be expanded and remaining variable may be solved:

\(r^{2} = (r-2\,ft)^{2}+(r-1\,ft)^{2}\)

\(r^{2} = r^{2}-4\cdot r +4 + r^{2}-2\cdot r +1\)

\(r^{2}-6\cdot r +5 =0\)

\((r-5)\cdot (r-1) = 0\)

\(r = 5\,ft\,\vee\,r = 1\,ft\)

According to the definition of hypotenuse, it must be longer than any of legs. Hence, there is just one solution that is reasonable:

\(r = 5\,ft\)

And length of the sides are, respectively:

\(x = 5\,ft-2\,ft\)

\(x =3\,ft\)

\(y = 5\,ft-1\,ft\)

\(y = 4\,ft\)

The length of the sides are 3 feet and 4 feet, respectively.

Answer:

The measure of the angle is 34 deg.

Step-by-step explanation:

Let the angle measure = x

"the supplement of an angle is twenty-four degrees less than five times the angle"

The supplement's measure is 5x - 24

The measures of supplementary angles is 180 deg.

x + 5x - 24 = 180

6x - 24 = 180

6x = 204

x = 34

Answer: The measure of the angle is 34 deg.

a. The Nyquist sampling rate for xa(t) can be calculated by taking twice the maximum frequency component in the signal. In this case, the maximum frequency component is 480л, so the Nyquist sampling rate is:

\(\displaystyle \text{Nyquist sampling rate} = 2 \times 480\pi = 960\pi \, \text{rad/sec}\)

b. The folding frequency is equal to half the sampling rate. Since the sampling rate is 600 samples/sec, the folding frequency is:

\(\displaystyle \text{Folding frequency} = \frac{600}{2} = 300 \, \text{Hz}\)

c. The corresponding discrete time signal can be obtained by sampling the analog signal at the given sampling rate. Using the sampling rate Fs = 600 samples/sec, we can sample the analog signal xa(t) as follows:

\(\displaystyle xa[n] = xa(t) \Big|_{t=n/Fs} = \sin\left( 480\pi \cdot \frac{n}{600} \right) + 6\sin\left( 420\pi \cdot \frac{n}{600} \right)\)

d. The frequencies of the corresponding discrete time signal can be determined by dividing the analog frequencies by the sampling rate. In this case, the discrete time signal frequencies are:

For the first term: \(\displaystyle \frac{480\pi}{600} = \frac{4\pi}{5}\)

For the second term: \(\displaystyle \frac{420\pi}{600} = \frac{7\pi}{10}\)

e. The corresponding reconstructed signal ya(t) can be obtained by applying an ideal digital-to-analog (D/A) converter to the discrete time signal. Since an ideal D/A converter perfectly reconstructs the original analog signal, ya(t) will be the same as xa(t):

\(\displaystyle ya(t) = xa(t) = \sin(480\pi t) + 6\sin(420\pi t)\)

The given double integral is ∫ ∫ (x² + y²)dx dy, and we need to evaluate it over the region in the positive quadrant where x+y≤1.

To evaluate this double integral, we can first determine the limits of integration for both x and y based on the given region. In the positive quadrant, x and y both range from 0 to 1.

Now, integrating the inner integral with respect to x, we get:

∫ (x² + y²)dx = (1/3)x³ + y²x + C1,

where C1 is the constant of integration.

Next, we integrate the resulting expression with respect to y:

∫ [(1/3)x³ + y²x + C1] dy = (1/3)x³y + (1/3)y³x + C1y + C2,

where C2 is another constant of integration.

Finally, we evaluate this double integral over the given region by substituting the limits of integration:

∫∫ (x² + y²)dx dy = ∫[0 to 1] ∫[0 to 1-x] (x² + y²)dy dx.

Performing the integration, we can find the numerical value of the double integral within the given region.

Step-by-step explanation:

Using De Morgan's Laws, we can write the negations for the given statement as: The negation will be "This computer program does not have a logical error in the first ten lines and it is not being run with an incomplete data set."

De Morgan's Laws are a set of logical rules that allow us to express the negation of a compound statement in terms of its original components. In general, De Morgan's Laws state that the negation of a conjunction (an "and" statement) is equivalent to a disjunction (an "or" statement) in which each component is negated, and the negation of a disjunction (an "or" statement) is equivalent to a conjunction (an "and" statement) in which each component is negated.

In the given statement, we have an "or" statement that links two possible causes for a problem in a computer program: a logical error in the first ten lines, or running the program with incomplete data. To negate this statement, we need to use De Morgan's Laws to express the opposite of this statement in terms of its original components.

According to De Morgan's Laws, the negation of an "or" statement is equivalent to an "and" statement in which each component is negated. Therefore, the negation of "This computer program has a logical error in the first ten lines or it is being run with an incomplete data set" is "This computer program does not have a logical error in the first ten lines and it is not being run with an incomplete data set." This means that the problem with the program is neither due to a logical error in the first ten lines nor to an incomplete data set.

Answer:

-12 = 3x - 4y

Step-by-step explanation:

Two points on the graph are (-4, 0) and (0, 3).  Moving from the first point to the second, we see x (the 'run') increase by 4 and y (the 'rise') increase by 3.  Thus, the slope of this line is m = rise / run = 3/4.

Using the point slope form, we get:

y - 3 = (3/4)(x - 0), or

4y - 12 = 3x, or

-12 = 3x - 4y (which is in Standard Form).
