GL is equal to √25 + L2, or √5 in its simplest radical form. The Pythagorean Theorem states that the sum of the squares of the two adjacent sides of a right triangle is equal to the square of the hypotenuse.

Given:

GL = ?

m∠KLH = 90°

KH = 5

We can use the Pythagorean Theorem to solve for GL.

GL2 = K2 + L2

GL2 = 52 + L2

GL2 = 25 + L2

Therefore, GL = √25 + L2 = √5.

Given GL, m∠KLH, and KH, we can use the Pythagorean Theorem to solve for GL. The Pythagorean Theorem states that the sum of the squares of the two adjacent sides of a right triangle is equal to the square of the hypotenuse. Therefore, we can calculate the square of GL by taking the square of KH and adding it to the square of L, which is unknown. We square 5 and get 25, then we add L2 to get 25 + L2. We can then take the square root of this to get GL. Therefore, GL is equal to √25 + L2, or √5 in its simplest radical form.

The probabilities are given as follows:

Fewer than 4 siblings: P(X < 4) = 0.737.

At least 5 siblings: P(X >= 5) = 0.111.

Not an only child: P(X > 1) = 0.734.

The probabilities are called identifying the desired outcomes from the distribution of the number of children per parent.

Hence the probability of fewer than 4 siblings is of

P(X < 4) = P(X = 1) + P(X = 2) + P(X = 3) = 0.266 + 0.322 + 0.149 = 0.737.

The probability of at least 5 siblings is of

P(X >= 5) = P(X = 5) + P(X = 6) + P(X > 6) = 0.059 + 0.032 + 0.02 = 0.111.

The probability that the student is not an only child is given as follows:

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. .The range is the resulting y-values we get after substituting all the possible x-values.

Step-by-step explanation:

The given curve is 4 - 6x - 7 + y = 0, so rearranging the equation, we get y = 6x + 3. By putting the value of y as -5 and 5, we get the corresponding values of x. For y = -5, we get x = -8/3, and for y = 5, we get x = 2/3.The curve intersects y-axis at (0, 3).

To find the area of the curve, we need to integrate the curve equation y = 6x + 3 from -8/3 to 2/3. So, the area under the curve is given by: {-8/3}^{2/3} 6x + 3 dx. We have the equation 4 - 6x - 7 + y = 0, so rearranging it, we get y = 6x + 3. This curve intersects y-axis at (0, 3).To find the area of the curve, we need to integrate the curve equation y = 6x + 3 from -8/3 to 2/3. The area under the curve is given by:{-8/3}^{2/3} 6x + 3 dx Let’s solve it, We get, {-8/3}^{2/3} 6x + 3 dx = [3x^2 + 3x] {-8/3}^{2/3} {-8/3}^{2/3} 6x + 3 dx = [18 - (-30)]/9 = 48/9 = 16/3 Therefore, the area under the curve is 16/3 units².

Thus, the area under the curve is 16/3 units².

To determine the sign of the sum of two integers when one integer is positive and the other is negative, we can follow a simple rule based on their magnitudes.

If the magnitude of the positive integer is greater than the magnitude of the negative integer, the sum will be positive. This is because the positive integer outweighs the negative integer, resulting in a positive value.

On the other hand, if the magnitude of the negative integer is greater than the magnitude of the positive integer, the sum will be negative. In this case, the negative integer dominates and determines the sign of the sum.

In both scenarios, the sign of the larger magnitude integer takes precedence and determines the sign of the sum. It is important to note that the sum will always have the sign of the integer with the larger magnitude, regardless of the specific values of the integers involved.

By considering the magnitudes of the integers, we can easily determine the sign of their sum when one integer is positive and the other is negative.

An convenient to make measurements in centimeters and grams  summary the conversions to 5t units are (a) 0.78 cm ≈ 0.078 5t units,(b) 126.2 s ≈ 126.2 5t units,(c) 42.4 cm³≈ 0.0424 t³,(d) 75.7 g/cm³≈ 75.7 t²

To convert the given measurements to 5t units,  to establish the conversion factors between centimeters/grams and 5t units.

1 t = 10 cm (since 1 meter = 100 cm and 1 meter = 10 t)

1 t = 1 kg (since 1 kg = 1000 g and 1 kg = 1 t)

Now, let's convert each measurement to 5t units:

(a) 0.78 cm:

To convert from centimeters to 5t units, we divide by 10 since 1 t = 10 cm.

0.78 cm / 10 = 0.078 t

Therefore, 0.78 cm is approximately 0.078 5t units.

(b) 126.2 s:

Since no conversion factor is given, we assume that 1 second remains the same in both systems. Thus, 126.2 s remains the same in 5t units.

Therefore, 126.2 s is approximately 126.2 5t units.

(c) 42.4 cm^3:

To convert from cm³to 5t units, we need to consider the conversion for volume, which is (1 t)³ = 1 t³= 1000 cm³

42.4 cm³ / 1000 = 0.0424 t³

Therefore, 42.4 cm³is approximately 0.0424 t³ in 5t units.

(d) 75.7 g/cm³:

To convert from g/cm³ to 5t units, we need to consider both the conversion for mass and volume. We have 1 g = 1/1000 kg = 1/1000 t and 1 cm^3 = 1/1000 t³

75.7 g/cm³ × (1/1000 t / 1/1000 t³) = 75.7 t / t³ = 75.7 t²

Therefore, 75.7 g/cm³ is approximately 75.7 t² in 5t units.

The value of the 10% trimmed mean is approximately 1.3027. To calculate the 10% trimmed mean, we need to trim off the lowest and highest 10% of the data and then find the mean of the remaining values.

First, let's sort the data in ascending order:

0.2, 0.21, 0.26, 0.3, 0.33, 0.41, 0.54, 0.57, 1.41, 1.7, 1.84, 2.2, 2.26, 3.06, 3.24

Next, we calculate the number of values to trim from each end:

10% of 15 (total number of values) = 0.1 * 15 = 1.5

Since we can't remove half a value, we round up to the nearest whole number, which is 2.

Now, we remove the two lowest and two highest values:

0.26, 0.3, 0.33, 0.41, 0.54, 0.57, 1.41, 1.7, 1.84, 2.2, 2.26

Finally, we calculate the mean of the remaining values:

(0.26 + 0.3 + 0.33 + 0.41 + 0.54 + 0.57 + 1.41 + 1.7 + 1.84 + 2.2 + 2.26) / 11 = 14.33 / 11 ≈ 1.3027

Rounding to four decimal places, the value of the 10% trimmed mean is approximately 1.3027.

To determine the z-score(s) that cover the "middle 98%" of the normal curve and represent the 98% confidence level (CL), we can use the properties of the standard normal distribution.

The "middle 98%" refers to the area under the normal curve between the z-scores that enclose the central 98% of the distribution. In a standard normal distribution, the mean is 0 and the standard deviation is 1.

Since the distribution is symmetric, we need to find the z-score(s) that correspond to the area of (1 - 0.98) / 2 = 0.01 on each tail of the distribution. The remaining 0.02 is split equally between the two tails.

To find the z-score(s), we can use a standard normal distribution table or a calculator.

Looking up the value of 0.01 in the z-table, we find that the z-score that corresponds to the lower tail is approximately -2.33. This means that 1% of the area lies to the left of z = -2.33.

To find the z-score for the upper tail, we use the symmetry of the distribution. The z-score that corresponds to the upper tail is the negative of the z-score for the lower tail, so it is approximately 2.33.

Therefore, the z-scores that cover the "middle 98%" of the normal curve and represent the 98% confidence level (CL) are approximately -2.33 and 2.33.
