Answer:

The statement that must be true about the values in the data set is: "No values in the data set are less than 8 or greater than 16."

Step-by-step explanation:

Mean is the average value of a dataset. In this case, the mean of the data set is given as 12.

Mean absolute deviation (MAD) measures the average distance between each data point and the mean of the dataset. In this case, the MAD is given as 4.

If each value in the data set varied from 12 by exactly 4, then the mean absolute deviation would be 4. However, in this case, the given mean absolute deviation is 4, which means the average deviation is 4, but individual values can deviate in both positive and negative directions.

The statement that half of the values in the data set are 8 and half of the values are 16 cannot be concluded based on the given information. The mean of 12 does not imply that half the values are 8 and the other half are 16.

Therefore, the only statement that can be confirmed as true based on the given information is: "No values in the data set are less than 8 or greater than 16."

First of all it's important to note that all parallelograms, rhombuses and squares are quadrilateral and they meet the following properties:

- Rhombus: quadrilateral whose four sides have the same length.

- Parallelogram: quadrilateral that has two pairs of parallel sides.

- Square: quadrilateral whose four sides and internal angles have the same length/measure.

With these definitions in mind we can solve the True or False table in the picture.

The first statement is false not every quadrilateral is a rhombus. For example rectangles that are not squares are not rhombuses since their four sides aren't all equal.

The second is true, as we saw before parallelograms are quadrilaterals. The same reason applies to the third statement, squares are qudrilaterals.

Now let's see the last statement. A rhombus with four right angles is a quadrilateral that has four equal sides (because it's a rhombus) and four equal angles (all measuring 90°). These are the conditions required for a quadrilateral to be considered a square so this last statement is true.

Then the answers are:

The sampling distribution model of p is a probability distribution that describes the possible values of a population proportion (p) based on a sample proportion (p-hat) from a random sample of the population. The assumptions that must be made for this description to be reasonable are:

If the sample is not randomly selected, it may not be representative of the population and the sample proportion may not accurately reflect the true population proportion.

A large sample size allows the sample proportion to be a good estimate of the true population proportion, this is due to the central limit theorem which states that as sample size increases, the distribution of the sample proportion becomes more normal and the standard deviation of the sampling distribution becomes smaller.

The population proportion must be well-defined and fixed for the sample proportion to be a good estimate of it. If the population proportion is not well-defined or changes based on the sample selected, then the sample proportion may not accurately reflect the true population proportion.

Independence of observations ensures that the outcome of one observation does not affect the outcome of another observation, this allows us to assume that the sample proportion is a good estimate of the population proportion.

If the sample is too large, it will be close to the population proportion, and therefore the sample proportion will not provide any new information.

Answer:

Step-by-step explanation:

The length, breadth, and height of the rectangular block are 256 cm, 192 cm, and 320 cm respectively.

To calculate the length, breadth, and height of a rectangular block whose ratio is 4:3:5 and its volume is 3840 cm3,

follow the steps below:

The ratio of length, breadth, and height is 4:3:5 respectively.

Therefore, assume the length to be 4x, the breadth to be 3x, and the height to be 5x, where x is the common factor.

Then, the volume of the block is calculated as:

Volume = length × breadth × height= 4x × 3x × 5x= 60x³

Since the volume of the block is 3840 cm³, we can equate the equation above to 3840 and solve for x, then find the

length, breadth, and height.

60x³ = 3840 x³ = 3840/60 x³ = 64

Length = 4x = 4 × 64 = 256 cm

Breadth = 3x = 3 × 64 = 192 cm

Height = 5x = 5 × 64 = 320 cm

Therefore, the length, breadth, and height of the rectangular block are 256 cm, 192 cm, and 320 cm respectively.

The study outlined above is an experiment. In the study, two firefly colonies are set up in a laboratory environment and are subjected to different conditions. Therefore, it is an experimental design as the researcher is actively manipulating the independent variable which is the exposure of fireflies to light.

An observational study would involve recording data on a subject without manipulating their environment or situation. An observational study would have a less controlled environment in which the researcher does not interfere with the study subjects. There is a control group and a treatment group. The control group is the colony that is exposed to normal daylight/darkness conditions. The treatment group is the colony that is exposed to continuous light. The control group is used to provide a baseline measure or standard of comparison for the experiment.

It provides a way to compare the difference between the treatment group and the control group. Thus, the control group is the normal light/darkness colony, and the treatment group is the continuous light colony.

Signed and unsigned integer expressions differ in how they interpret and represent numerical values. Signed integers can represent both positive and negative values, while unsigned integers can only represent non-negative values.



1. Signed Integer Expressions: Signed integers are capable of representing positive, negative, and zero values. They allocate a bit for the sign, typically using the leftmost bit (the most significant bit). The remaining bits are used to represent the magnitude of the number. The sign bit is set to 0 for positive or zero values and set to 1 for negative values. This representation allows for a wider range of values, but half of the possible bit patterns are reserved for negative numbers, limiting the maximum positive value that can be represented.

2. Unsigned Integer Expressions: Unlike signed integers, unsigned integers do not allocate a bit for the sign. Instead, all bits are used to represent the magnitude of the number, allowing for a wider range of non-negative values. As a result, unsigned integers can represent larger positive values than their signed counterparts. However, they cannot represent negative values or zero, as there is no reserved bit to indicate the sign.

The choice between signed and unsigned integer expressions depends on the specific requirements of a program. Signed integers are typically used when negative values need to be represented or when arithmetic operations may result in negative values. On the other hand, unsigned integers are useful when dealing with quantities that are always expected to be positive, such as array indices or lengths of data structures. It's important to consider the range of values required and the potential impact of overflow or underflow when selecting between signed and unsigned integer expressions.

The maximum height reached by the ball is 30 feet. Option C

To find the maximum height reached by the ball, we need to determine the vertex of the parabolic function represented by the equation h = \(-16t^2 + 40t + 5.\)

The vertex of a parabola in the form y = ax^2 + bx + \(ax^2 + bx + c\) is given by the formula x = -b / (2a), which gives us the x-coordinate of the vertex. In this case, a = -16 and b = 40.

Using the formula, we can calculate the x-coordinate of the vertex:

x = -b / (2a) = -40 / (2*(-16)) = -40 / (-32) = 1.25

To find the corresponding y-coordinate (maximum height), we substitute the x-coordinate back into the equation:

h \(= -16(1.25)^2 + 40(1.25) + 5\) = -16(1.5625) + 50 + 5 = -25 + 55 = 30

Therefore, the maximum height reached by the ball is 30 feet.

Answer:

a) The length of the virus in millimetres is 0.000 07 mm.

b) Viruses are microscopic and so nanometres are the more appropriate unit for writing the length of the virus since the nanometre is a smaller unit of measurement than the millimetre.

Step-by-step explanation:

SI is the abbreviation for The International System of Units.

The SI base unit for length is metres (m).

Milli and nano are SI prefixes used to form decimal multiples or submultiples of SI units.

Therefore, to convert nanometres to millimetres, multiply the nanometres by 10⁻⁶:
