The ladder will reach 15 feet length up the building.

1. The ladder is 20 feet long

2. The ladder is set up 5 feet from the base of the building

3. Subtract the 5 feet from the length of the ladder (20 feet)

4. The answer is 15 feet

The 20-foot ladder is set up 5 feet from the base of the building. To calculate how far up the building the ladder reaches, we need to subtract the 5 feet from the length of the ladder. The answer is 15 feet. This means the ladder will reach 15 feet up the building (5 feet from the base). This can also be visualized by imagining that the remaining 15 feet of the ladder is being used to reach up the building. The 5 feet of the ladder not used to reach up the building is used to support the ladder on the ground.

Zeros to the right of a number are significant as long as there is a decimal point present are described the the significance of zeros in a reported number.

Significant Zeros : If a zero is found between significant digits, it is valid. If the number is decimal, zeros can be used as placeholders (meaningless) to the left of significant digits. For example, if the mass is 32 g, there are 2 significant digits. Expressed in kilograms, the mass of 0.032 kg should have two significant digits. The zeros to the right of the decimal point that are not just placeholders are significant. These significant zeros are to the right of any significant non-zero digits. The zeros to the left of the 20.00 cm decimal point are also significant, as they are among the significant digits. If a decimal point is present, all digits from the first non-zero digit (to the right) are significant. If there is no decimal point, trailing zeros are considered insignificant unless scientific notation makes the quantity clear.

The equation of the piecewise function is:

        { 5/3(x),  -4 ≤ x≤ -1

f(x) = { 2,          -1 ≤ x ≤ 3

        {-2,          3 ≤ x ≤4

A piecewise function is a function that is defined by multiple sub-functions, each of which applies to a certain range of the input (or domain) values.

In the graph, we have five points with coordinates (-4, -3), (-1, 2), (3, 2), (3, -2) and (4, -2)

To find the f(x) for (-4, -3) to (-1, 2):

First, find the slope using slope = (y2-y1)/(x2-x1)

Slope = (2-(-3)) / (-1-(-4)) = 5/3

f(x) = 5/3(x)

For  (-1, 2) to (3, 2):

f(x) = 2

For (3, -2) to (4, -2):

f(x) = -2

Therefore, the equation of the piecewise function will be:

By using The Pythagoras theorem, the expression g = f/2 represents the relationship between g and f if j = h and k = m option (A), i.e. g = 1/2  is correct.

Pythagoras theorem:

The Pythagorean Theorem, also known as the Pythagorean Theorem, describes the relationship between the three sides of a right triangle. According to the Pythagorean theorem, the square of the hypotenuse equals the sum of the squares of the other two sides of the triangle. If AB and AC are the sides and BC is the hypotenuse of the triangle then BC2 = AB2 + AC2 .where AB is the base, AC is the height or altitude and BC is the hypotenuse.

The area of ​​the square formed by the longest sides (hypotenuses) of right-angled triangles is equal to the sum of the areas. The number of squares formed by the other two sides of a right triangle. In a right triangle, the formula for the Pythagorean theorem is expressed as:

c² = a² + b²

where

'c' = hypotenuse of a right triangle

'a' and 'b' are the other two legs.

In the question:

It is given that:

If j = h and k = m

From the given question, C is a right-angle triangle as j = h and k = m

From the definition of the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides

         h² +k²= g²

From the triangle ΔABC

(j + h)² +(m + h)² = f²

⇒ (h + h)² +(k+ k)² = f²

⇒ (2h)² +(2k)²= f²

⇒ 4h²+ 4k² = f²

⇒ 4(h²+k²) = f²

⇒ 4×g² = f²

⇒ (2g)² = f²

⇒ 2g = f

⇒ g = f/2

Thus, the expression g = f/2 represents the relationship between g and f if j = h and k = m option (A) is correct.

The interquartile range is a useful tool for measuring variability in a set of data because it overcomes the difficulty of the range being influenced too much by extreme values

The interquartile range is a measure of variability that is commonly used in statistics to describe the spread of a set of data. It is particularly useful because it overcomes the difficulty of the range being influenced too much by extreme values.

In mathematical terms, the interquartile range is defined as the difference between the upper quartile (Q3) and the lower quartile (Q1).

The upper quartile represents the 75th percentile of the data and the lower quartile represents the 25th percentile of the data.

This means that 25% of the data falls below the lower quartile and 75% of the data falls above the upper quartile.

The interquartile range provides a better representation of the spread of the data because it eliminates the influence of extreme values.

These values, also known as outliers, can have a significant impact on the range and can make it appear as though the data is more spread out than it actually is.

By using the interquartile range, the outliers are excluded and a more accurate representation of the spread of the data is obtained.

Therefore, option (a) is correct.

Answer:

The length of the short side was 12 and the length of the long side was 32

Step-by-step explanation:

We will say that the length is the shorter side, and be using l as the variable, and that width is the longer side, and be using w as the variable. The first two equations we have are:

w = l + 20

And

2(2l + 3w) = 240

We will start with the second equation, then substitute in the first equation for w. We have:

4l + 6w = 240

Divide both sides by 2:

2l + 3w = 120

Then, we substitute in l + 20 for w, giving us:

2l + 3l + 60 = 120

Subtract 60 from both sides and combine like terms:

5l = 60

l = 12

So, the original length was 12, now substituting this into our first equation gives us:

w = 12 + 20 = 32

So the original width was 32. So, the length of the short side was 12 and the length of the long side was 32.

A quartile is a particular kind of quantile that splits the total number of data points into four roughly equal portions, or quarters. Quartiles are a type of order statistic since they require the data to be arranged from smallest to largest in order to be computed.

The median of the data set is the number in the midpoint between the smallest number (minimum) and the first quartile (Q1).

The median of a data set is known as the second quartile (Q2).

The median value and the highest value (maximum) in the data set are the two values that make up the third quartile (Q3).

To find the quartiles, first, we need to put the data in ascending order.

65,  68,  70,  70,  71,  72,  73,  74,  75,  77,  77,  78,  80

The value of Q₂ [Median] is on the 7th value, which is 73

The value of Q₁, the lower quartile, is the 3.5th value [(3rd value+4th value)/2] , which is 70

The value of Q₃, the upper quartile, is the 10.5th[(10th value+11th value)/2]  value, which is 77
