Step-by-step explanation:
diameter
The another name for the chord that passes through the center of the circle is the diameter.
The correct option is (A).
What is a circle?A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point.
As per the given data:
We have to find out the alternate name for a chord that passes through the center of a circle out of the given options.
Diameter:
It's a chord that passes through the center and touches the ends of the circumference of the circle.
Hence, this is correct.
Circumference:
It's the length of the boundary of a circle, hence this cannot be a chord.
This is incorrect.
Center:
It's a point and a chord is a line, hence this cannot be true.
Radius:
A radius is not a chord, as it does not touch the endpoints on the circumference of the circle.
The another name for the chord that passes through the center of the circle is the diameter.
Hence, The another name for the chord that passes through the center of the circle is the diameter.

If f(x) = â’2 8, what is f(â’1. 8)? 4 6 10 12.
Answers
Answer:
f(x) = [x] - 2 + 8
[x] is the notation for 'greatest integer function'
f(-1.8) = [-1.8] - 2 + 8 = -2 -2 + 8 = 4
The answer is 4
Step-by-step explanation:
The value of the function f(x) = [x] - 2 + 8 when x = -1.8 is 12
Given the function f(x) =[x] - 2 + 8, we need to find f(-1.8)
To get the value of f(-1.8), we will simply substitute x = -1.8 into the function to have:
f(-1.8) = -1.8 - 2 + 8
f(-1.8) = -3.8 + 8
f(-1.8) = 11.8
Since x is in a square bracket, we will round the value up to the nearest whole number, hence;
f(-1.8) = 12
Therefore the value of the function f(x) = [x] - 2 + 8 when x = -1.8 is 12

c. The Binomial distribution which has n = 10, p = 0.5
d. The Poisson distribution which has λ = 5.0
Answers
To find the probability distribution for the given functions, we can use the formulas for the Binomial and Poisson distributions.
a. The Binomial distribution with \(\(n = 20\)\) and \(\(p = 0.05\)\) is given by:
\(\[P(X=k) = \binom{n}{k} \cdot p^k \cdot (1-p)^{n-k}\]\)
where \(\(X\)\) is the random variable representing the number of successes, \(\(k\)\) is the specific number of successes, \(\(\binom{n}{k}\)\) is the binomial coefficient, \(\(p\)\) is the probability of success, and \(\(1-p\)\) is the probability of failure.
b. The Poisson distribution with \(\(\lambda = 1.0\)\) is given by:
\(\[P(X=k) = \frac{{e^{-\lambda} \cdot \lambda^k}}{{k!}}\]\)
where \(\(X\)\) is the random variable representing the number of events, \(\(k\)\) is the specific number of events, \(\(e\)\) is the base of the natural logarithm, \(\(-\lambda\)\) is the negative of the mean \((\(\lambda\))\) , and \(\(k!\)\) is the factorial of \(\(k\)\) .
c. The Binomial distribution with \(\(n = 10\)\) and \(\(p = 0.5\)\) is given by the same formula as in part (a):
\(\[P(X=k) = \binom{n}{k} \cdot p^k \cdot (1-p)^{n-k}\]\)
d. The Poisson distribution with \(\(\lambda = 5.0\)\) is given by the same formula as in part (b):
\(\[P(X=k) = \frac{{e^{-\lambda} \cdot \lambda^k}}{{k!}}\]\)
These formulas allow us to calculate the probabilities for different values of \(\(k\)\) in each distribution, where \(\(k\)\) represents the specific outcome or number of events of interest.

Compare the data from the experiment to the public opinion poll. How does the data collected compare to the media source? Describe the trends in the data and compare the theoretical probability to the empirical probability.
Answers
Comparing experiment data to public opinion polls helps evaluate media accuracy, detect biases, and understand the influence on public opinion, while describing data trends and comparing theoretical and empirical probabilities aids in making informed decisions.
Data from an experiment and a public opinion poll have distinct characteristics. Experiment data is obtained through controlled studies, measuring the effects of a variable on another variable. Public opinion polls, however, rely on subjective input from individuals to gauge public sentiment. While both types of data have their significance, comparing the collected data to media sources helps assess accuracy, detect biases, and understand the media's influence on public opinion. Describing trends in the data involves identifying patterns or movements over time, while comparing theoretical probability (calculated mathematically) to empirical probability (based on observed data) aids in understanding likelihoods. These evaluations contribute to obtaining reliable and unbiased data for informed decision-making.In conclusion, comparing the data collected from experiments to public opinion polls allows for the assessment of media accuracy and biases, while analyzing data trends and comparing theoretical and empirical probabilities provides valuable insights for decision-making.

if the numerator of a fraction is increased by 4, the value of the resulting fraction is 3/4. if the denominator of the original fraction is increased by 2, the value of the resulting fraction is 1/2. find the original fraction
Answers
The original fraction is -5. Note that this is a negative fraction, which may not be meaningful in certain contexts.
Let's call the original fraction "x".
From the first condition, we have:
x + 4 / x's denominator = 3/4
From the second condition, we have:
x / (x's denominator + 2) = 1/2
We can substitute x's denominator in the first equation with (x's denominator + 2) from the second equation:
x + 4 / (x's denominator + 2) = 3/4
Next, we can cross-multiply and solve for x:
4x + 16 = 3x's denominator + 6
x's denominator = 4x + 10
Substituting back into the second equation:
x / (4x + 10) = 1/2
Multiplying both sides by (4x + 10) to isolate x:
2x = 4x + 10
Solving for x:
-2x = 10
x = -5

. Solve for x in the equation log (7x+5) -log(x - 1) = 1(with full working
Answers
Answer:
Step-by-step explanation:
To solve this equation, we can start by using the logarithm property that states: log(a) - log(b) = log(a/b).
Then, we can apply this property to the left side of the equation:
log (7x+5) - log(x - 1) = log((7x+5)/(x - 1)) = 1
Next, we can rewrite the right side of the equation as:
log((7x+5)/(x - 1)) = log(7x+5) - log(x - 1) = 1
Now, we can use the inverse property of logarithms, which states: log(a) = b, then a = 10^b, to solve for x.
This gives us: (7x+5)/(x - 1) = 10
We can then cross-multiply and simplify to get: 7x+5 = 10x - 10
This equation simplifies to: 3x = -5
Dividing both sides by 3 gives us: x = -5/3
Therefore, the solution to the equation is x = -5/3.

Work out the area of the triangle in cm”.
B x W x = 2
Total marke: 4
Answers
Answer:
\(A=384\ cm^2\)
Step-by-step explanation:
Let the sides of a triangle be 6x,8x and 10x.
Perimeter of the triangle, P = 96 cm
We need to find the area of the triangle.
P = sum of all sides
6x+8x+10x = 96
24x = 96
x = 4
Sides are :
6x = 6(4) = 24 cm
8x = 8(4) = 32 cm
10x = 10(4) = 40 cm
Area,
\(A=\dfrac{1}{2}\times b\times h\\\\A=\dfrac{1}{2}\times 24\times 32\\A=384\ cm^2\)
So, the area of the triangle be \(384\ cm^2\).
