An independent basic service set (IBSS) consists of how many access points?
An independent basic service set (IBSS) does not consist of any access points.
In an IBSS, devices such as laptops or smartphones connect with each other on a peer-to-peer basis, forming a temporary network. This type of network can be useful in situations where there is no existing infrastructure or when devices need to communicate with each other directly.
Since an IBSS does not involve any access points, it is not limited by the number of access points. Instead, the number of devices that can be part of an IBSS depends on the capabilities of the devices themselves and the network protocols being used.
To summarize, an IBSS does not consist of any access points. Instead, it is a network configuration where wireless devices communicate directly with each other. The number of devices that can be part of an IBSS depends on the capabilities of the devices and the network protocols being used.

Find the rate of interest per annum at which ₹ 5000 will amount to ₹ 6, 050 in 3
years.
Answer:
7%
Step-by-step explanation:
Using the formula
Amount = Principal + Interest
Give the following
Principal = ₹ 5000
Amount =₹ 6050
Time = 3 years
Required
Time
Substitute into the formula
A = P + I
A = P + PRT/100
6050 = 5000 + 5000(R)(3)/100
6050 - 5000 = 150R
1050 = 150R
R = 1050/150
R = 7
Hence the rate of interest is 7%
You have a summer job cleaning swimming pools. Pools are cleaned with pumps and filters. Water is pumped into the filter to remove particles that make the water less clear. A unit called NTU¹ is used to measure how clear water is. For example, in a pool: . 0.1 NTU is considered clean, safe water. 0.9 NTU has too many particles to be clean, safe water. • In this task you will determine how long a pump needs to operate in order to clean the water in a large pool. Nephelometric Turbidity Units 3 JEWELEAH In the same large pool, the measurement is currently 0.8 NTU. When the pool opens in the morning, the measurement needs to be 0.4 NTU. Your manager claims that this will be done if you run the pump for 4 hours because 10% is 0.10 and 0.8 -0.10 0.10 - 0.10 - 0.10 = 0.4. He is incorrect. Complete the chart below to determine what the NTU measurement would be after running the pump for 4 hours. Round your answers to the nearest hundredth. Hours 0 1 2 3 4 hp NTU 0.80
After running the pump for 4 hours, the NTU measurement would be approximately 0.52.
How to solve this problemTo determine the NTU measurement after running the pump for 4 hours, we need to consider that the pump reduces the NTU by 10% each hour.
Here's the chart with the NTU values for each hour, rounded to the nearest hundredth:
Hours | NTU
0 | 0.80
1 | 0.72 (0.80 * (1 - 0.10) = 0.80 * 0.9)
2 | 0.65 (0.72 * (1 - 0.10) = 0.72 * 0.9)
3 | 0.58 (0.65 * (1 - 0.10) = 0.65 * 0.9)
4 | 0.52 (0.58 * (1 - 0.10) = 0.58 * 0.9)
After running the pump for 4 hours, the NTU measurement would be approximately 0.52.

The length of one of two chords of a circle is 12 cm. If the chords are 6 cm and 7 cm respectively away from the centre of the circle, calculate the length of the second chord...
Please with explanation
Answer:
2√23 cm or 9.59 cm to the nearest hundredth
Step-by-step explanation:
The 12 cm chord is 6 cm away from the centre and the other chord is 7 cm away from the centre.
If we draw 4 radii from the ends of the 2 chords to the centre and 2 lines perpendicular from the centre to the 2 chords we have 2 pairs of congruent right triangles.
So by Pythagoras:
r^2 = 6^2 + 6^2 ( the given chord)
r^2 = 7^2 + x^2 where x is 1/2 * length of the second chord.
Therefore:
7^2 + x^2 = 6^2 + 6^2
x^2 = 36+ 36 - 49 = 23
x = √23
and length second chord = 2√23.

a)Critical points are :
Determine the extreme values on[0,π/2]
b)Minimum is
c)Maximum is
a) Critical points are: π/4. b) The endpoints of the interval and at the critical points is 1. c) Maximum is √2 (at x = π/4).
a) To find the critical points of f(x) = sin(x) + √1*cos(x) on the interval [0, π/2], we first need to find the derivative of f(x) with respect to x. Using the chain rule, we have:
f'(x) = cos(x) - √1*sin(x)
Now, we need to find the values of x for which f'(x) = 0:
cos(x) - √1*sin(x) = 0
cos(x) = sin(x)
Since the interval is [0, π/2], the only solution to this equation is x = π/4.
a) Critical points are: π/4.
b) To determine the extreme values on [0, π/2], we need to evaluate f(x) at the endpoints of the interval and at the critical points:
f(0) = sin(0) + √1*cos(0) = 0 + 1 = 1
f(π/4) = sin(π/4) + √1*cos(π/4) = (√2)/2 + (√2)/2 = √2
f(π/2) = sin(π/2) + √1*cos(π/2) = 1 + 0 = 1
b) Minimum is: 1 (at x = 0 and x = π/2)

Blank 1; The Pythagorean Theorem
Blank 2; Square root of 73
Blank 3; A leg
Blank 4; The hypotenuse
Blank 5; 9.4 cm
What is the Pythagorean Theorem?Pythagoras Theorem indicates that the square of the longest side of a right triangle is equivalent to the sum of the square of the other two sides.
The diagonals from point A to point G in the cuboid can be found using Pythagoras Theorem as follows;
The diagonal of the base rectangle, ABCD, is found as follows;
AC = √(8² + 3²) = √(73)
Using the side CG as the leg of the right triangle ΔACG, with AG being the hypotenuse, we get;
CG = 4 indicated in the diagram in the question
(AG)² = (AC)² + (CG)²
(AG)² = 73 + 4² = 89
AG = √(89) ≈ 9.4
The completed statement is therefore;
To find the length of the diagonal from point A (front/bottom /left) to point G (back/top/right); You would first use the Pythagorean Theorem on the bottom of the box rectangle to find the diagonal AC = square root 73 cm.

tossing a fair coin 20 times and counting the number of heads (x). what is the chance that the number of heads is 13 or more?
By using Binomial Distribution of probability, it is obtained that
Probability that the number of heads is 13 or more = \(137980(\frac{1}{2})^{20}\)
What is Binomial Distribution?
Binomial distribution is a discrete type probability distribution whose probability mass function is
P(X = k) = \({n \choose k} p^k(1 - p)^{n-k}\)
p is the probability of success.
Here Binomial distribution of probability is used
P(X \(\geq\) 13) = P(X = 13) + P(X = 14) + ........ + P(X = 20)
P(X = 13) = \({20 \choose 13} (\frac{1}{2})^{13}( 1 - \frac{1}{2}})^{20-13}\)
= \({20 \choose 13} (\frac{1}{2})^{13}( \frac{1}{2}})^{7}\)
=\({20 \choose1 3} (\frac{1}{2})^{20}\)
P(X = 14) = \({20 \choose14} (\frac{1}{2})^{20}\)
P(X = 20) = \({20 \choose20} (\frac{1}{2})^{20}\)
Total Probability = \(({20 \choose 13} + {20 \choose 14} + .... {20 \choose 20})(\frac{1}{2})^{20}\)

a gardener has 1040 feet of fencing to fence in a rectangular garden. one side of the garden is bordered by a river and so it does not need any fencing. garden bordered by a river what dimensions would guarantee that the garden has the greatest possible area?
The dimensions 520 by 360 feet would guarantee that the garden has the greatest possible area .
Let length be l and width be b of garden .
According to question ,
l + 2b = 1040
Area of garden = l * b
Substituting value of l in formula for area ,
Area = ( 1040 - 2b ) * b = 1040b - 2\(b^{2}\)
Taking derivative of Area wrt. b and putting it equal to 0 ,
1040 - 4b = 0
b = 1040 / 4
b = 260 feet
Therefore , l = 1040 - 520 = 520 feet .
Maximum Area = 260 * 520 = 135200 \(feet^{2}\) .

Remy walked to a friends house, m miles away, at an average rate of 4mph. The m-mile walk home was at only 3mph. Remy spent 2 hours walking in all. Find the value of m.
Step-by-step explanation:
speed = mph or miles/hour
so, when we are dealing with a distance and compare the time spent on the distance, we have to divide distance by speed
miles / miles/hour = hour
so, we have
m/4 + m/3 = 2
as the sum of the time it took to walk the distance at 4mph and the time it took to walk the distance at 3 mph is 2 hours.
now we multiply by the denominators one after the other to eliminate the fractions.
m + 4m/3 = 8
3m + 4m = 24
7m = 24
m = 24/7 = 3.428571429... miles

A 2020 study showed that the presence of male pattern baldness and a severe reaction to COVID-19 had a strong association, so some suggested that having male pattern baldness might somehow cause a person to have a severe reaction to COVID-19 (since they had been bald before catching COVID-19, so that the disease could not have caused their baldness). Which option below was most likely a lurking variable?
Age
Diet
Height
Weight
Age is the most likely lurking variable in this scenario.
What is height?Height is a measure of how tall or high something is, typically referring to the distance from the bottom to the top of an object or the distance between a surface and the top of an object above it. Height can be measured in various units such as meters, feet, or inches. For example, the height of a person, a building, or a mountain can be measured in meters or feet.
Given by the question: -
As people age, they are more likely to experience male pattern baldness, and they are also at higher risk of severe illness from COVID-19. Therefore, the association between male pattern baldness and severe COVID-19 may be due to age rather than any direct causal link between baldness and COVID-19 severity. It is important to account for potential lurking variables in any study to avoid drawing incorrect conclusions about causation.

A firm experiences increasing returns to scale if inputs are doubled and output more than doubles.
When the firm's output grows at a faster rate than the growth in inputs, increasing returns to scale result. In this case, the company experiences economies of scale, which makes it more effective as it grows its production.
The firm is able to boost productivity and efficiency as it expands its scale of operations if inputs are doubled and output more than doubles.
This can be ascribed to a number of things, including specialisation, labour division, the use of capital-intensive technology, discounts for bulk purchases, and spreading fixed costs over a higher output. Lower average costs per unit of output result in higher profitability and competitiveness for the company.
The firm gains a number of benefits from growing returns to scale. First off, it lets the company to benefit from cost savings brought about by economies of scale, allowing it to manufacture goods or services for less money per unit.
