his sample. This is an example of
OA. systematic
B. quota
C. random
D. cluster

The probability that at least 9 of the students selected are undergraduate students is 0.244.

This is a binomial distribution

We have

n = 10

probability = 0.75

1-p = 1- 0.75 = 0.25

The probability of at least 9 =

p 0f 9 + p of 10

= 10C9 (0.75)⁹ (0.25) + (0.75)¹⁰

= 10 x 0.0751 x 0.25 + 0.0563

= 0.244

Hence the probability that at least 9 of the selected are undergraduates is 0.244.

The sample proportion is given as 5.

To solve for the sample proportion:

The sample proportion is denoted by

[tex]p= \frac{y}{n}[/tex]

Where,

y: is the number of observations that possess some special characteristic

n: is the total number of observations in the sample.

We have the following info:

y= 600

n= 120

Therefore, the sample proportion is:

600/120

=5.

The examples of construct that the research test can be measuring include:

It should be noted that construct validity simply means the extent to which a test accurately assesses what it's meant to assess.

The way to improve the test is to ensure that the measurements and indicators are carefully developed based on the existing knowledge.

The method of estimating reliability that would be used for the test is the split-half method. This is important as it assesses the internal consistency of a test.

The examples of error that can be witnessed on the test include procedural error, environmental error, and human error.

Lastly, trait error is the error that is attributed to the individual which brings about the difference between the true and observed scores while method error is the error that occurs in measurement such that the value obtained is different from the actual value.

Option a. The total force that is calculated is given as 24 n/s

300 g = 0.3kg

Force = change in momentum / time

We have to find the mass x velocity

0.3 x 40 = 12kg m / s

This rubber ball is said to strike and also rebound immediately. We can take the time as 1 second.

Force 1 x 12

= 12 N

The force that is exerted after the rebounding has occurred is also 12 N following Newton's 3rd law.

Answer:

Address Resolution Protocol

Explanation:

ARP is a protocol that helps devices on a network find each other by translating IP addresses into MAC addresses.

ARP stands for Address Resolution Protocol. It is a communication protocol used in computer networks to translate an IP (Internet Protocol) address into a MAC (Media Access Control) address.

In simpler terms, it helps devices on a network to find each other and establish a connection.

When a device wants to send data to another device, it needs to know the MAC address of the recipient.

ARP allows the device to find the MAC address by sending out a broadcast message to all devices on the network, asking "Who has this IP address?".

The device with the matching IP address responds with its MAC address, allowing the sender to establish communication.

The value of f(2p), given that f(2) = 5 and p is a constant is -3 (option A)

First, we shall obtain the value of p. Details below:

f(x) = x - p

But,

f(2) = 5

5 = 2 - p

Collect like terms

p = 2 - 5

= -3

Finally, we shall obtain the value of f(2p). Details below:

f(x) = x - p

But

x = 2p

f(2p) = 2p - p

f(2p) = p

But

p = -3

Thus,

f(2p) = -3

Therefore, we can conclude that the value of f(2p) is -3 (option A)

Based on Chebyshev's theorem we can be 89% sure that between 0 and 12 of the products will be improperly packaged.

The chance of happening an event out of all the possible outcomes is called the probability of an event.

A packaging company has an old machine which improperly packages 30% of all its goods. The company has a special order to package 20 products for a client.

The probability that goods are improperly packaged is 0.30 and sample size is 20.

Then, μ = 20 x 0.30 =6

standard deviation, σ = √ [np(1-p)]

Put the values, we get

σ  = 2.05

The value of k  can be

1-1/k² = 0.89

Solving the expression for k, we get

k = 3.01

Based on Chebyshev's theorem, the limit are

μ ± kσ = (μ - kσ , μ + kσ )

          ={(6 - (3.01 x 2.05)) , (6 + (3.01 x 2.05)) }

          ={0,12}

Thus, we can be 89% sure that between 0 and 12 of the products will be improperly packaged.

If there is no restriction, the number of ways in which a committee consisting of 2 Mathematician and 3 Statistician can be formed is given by:

Number of ways = ⁵C₂ × ⁷C₃

Number of ways = [5!/(2! × (5 - 2)!) × 7!/(3! × (7 - 3)!)]

Number of ways = [5!/(2! × 3!) × 7!/(3! × 4!)]

Number of ways = 20/2 × 210/6

Number of ways = 10 × 35

Number of ways = 350 ways.

If one particular Statistician should be included, the number of ways in which a committee consisting of 2 Mathematician and 3 Statistician can be formed is given by:

Number of ways = ⁵C₂ × ⁶C₂

Number of ways = [5!/(2! × (5 - 2)!) × 6!/(2! × (6 - 2)!)]

Number of ways = [5!/(2! × 3!) × 6!/(2! × 4!)]

Number of ways = 20/2 × 30/2
