how do I graph and understand points on a graph like these
Answers
Option B has these points on the graph: (1, 100) and (2,50)
Explantion:
The given function:
\(f(x)=100(0.5)^{x-1}\)To determine which of the graph defines the function above, we will assign values for x based on the numbers given:
The values of x on the graph: 0, 1, 2, 3, 4, 5
Then we will insert the values of x in the function to see if we will get the same coordinates as any one of the graph.
let y = f(x)
when x = 1
\(\begin{gathered} y=100(0.5)^{1-1}=100(0.5)^0 \\ y\text{ = 100}\times1\text{ = 100} \\ (x,y)\text{ = (1, 100)} \end{gathered}\)Let's pick another x point: when x = 2
\(\begin{gathered} y=100(0.5)^{2-1}=100(0.5)^1 \\ y\text{ = 100(0.5) = 50} \\ (x,y)\text{ = (2, 50)} \end{gathered}\)We can continue with the points to be sure. But let's check which of the graph has this points.
From the above, option B has these points: (1, 100) and (2,50)

What is P(B)?
A) 0.1
B) 0.375
C) 0.25
D) 0.667
Answers
The calculated value of the probability of B is (c) 0.25
How to calculate the probability of BFrom the question, we have the following parameters that can be used in our computation:
P(A or B) = 0.3
P(A and B) = 0.2
P(A/B) =0.8
First, we have
P(A/B) = P(A and B)/P(B)
Substitute the known values in the above equation, so, we have the following representation
0.2/P(B) = 0.8
So, we have
P(B) = 0.2/0.8
Evaluate
P(B) = 0.25
Hence, the probability of B is 0.25

The distribution of values taken by a statistic in all possible samples of the same size from the same population is None of the above The population parameter The sampling distribution of the statistic The probability that the statistic is obtained The variance of the values
Answers
The sampling distribution of a statistic is the distribution of values taken by the statistic in all possible samples of the same size from the same population.
The population parameter is the true value of the statistic for the entire population. The probability that the statistic is obtained is the probability that it will be obtained in a single sample from the population. The variance of the values is the amount of variation among the values of the statistic in the sample. The formula for calculating the variance is the sum of the squared deviations from the mean, divided by the number of values in the sample. This can be written mathematically as: Variance = Σ (x - X)2/ n, where x is each value in the sample, X is the mean value, and n is the number of values in the sample.

a like that includes the points (s,-3) and (-8,-4) has a slope of 1/4.
Answers
The value of s in the point (s,-3) after using slope formula is -4.
What is slope?
Slope is a term used to define how steep a line is. The rise of a line over the run of a line, or the change in the vertical direction (y) over the change in the horizontal direction, is the definition of slope (x). The slope is the angle at which one is moving forward or backward when skiing down a hill or climbing a mountain. Depending on what it is, the slope may occasionally be fairly flat or extremely steep. The slope of an object indicates how steep it is. Slope knowledge is crucial for daily decision-making.
Using slope formula,
=> slope m = \(\frac{y_2-y_1}{x_2-x_1}\)
Now the given point is ,
\((x_1,y_1)=(s,-3) \\(x_2,y_2)=(-8,-4)\)
=> slope m= 1/4
=> \(\frac{1}{4}= \frac{-4+3}{-8-s}\)
=> \(\frac{1}{4} = \frac{-1}{-8-s}\)
=> -8-s=-4
=>-s=-4+8
=> -s=4
=> s =-4.
Hence the value of s is -4.

Roland has built a circuit, and is using a device called an
ammeter to measure how quickly electrical current is flowing
through the circuit. He calculates that the current should be
0.180 amps, but he measures the current as 0.173 amps. What
is Roland's percent error?
Answers
Roland's percent error is approximately 3.889%.
This means that his measured value differs from the actual value by 3.889% or 0.03889 in decimal form.
The positive sign indicates that Roland's measured value is slightly lower than the actual value.
To calculate Roland's percent error, we can use the formula:
Percent Error = (|Measured Value - Actual Value| / Actual Value) \(\times\) 100
Given that Roland measured a current of 0.173 amps while expecting a current of 0.180 amps, we can substitute these values into the formula:
Percent Error = (|0.173 - 0.180| / 0.180) \(\times\) 100
Simplifying the expression within the absolute value:
Percent Error = (|-0.007| / 0.180) \(\times\) 100
Since the absolute value of -0.007 is 0.007, we have:
Percent Error = (0.007 / 0.180) \(\times\) 100
Calculating the division:
Percent Error = 0.03889 \(\times\) 100
Percent Error = 3.889%.

Find the dimensions of the box with volume 8000 cm3 that has minimal surface area. (Let x, y, and z be the dimensions of the box.)
Answers
Answer:
\(x = y = z = 20\)
Step-by-step explanation:
Given
\(Volume = 8000cm^3\)
Required
Determine the dimensions that minimizes the surface area.
Surface area of a box is;
\(S = 2(xy + xz + yz)\)
Volume of a box is:
\(V = xyz\)
Make z the subject
\(z = \frac{V}{xy}\)
Substitute 8000 for V
\(z = \frac{8000}{xy}\)
Substitute 1000/xy for z in \(S = 2(xy + xz + yz)\)
\(S = 2(xy + x\frac{8000}{xy}+y\frac{8000}{xy})\)
\(S = 2(xy + \frac{8000}{y}+\frac{8000}{x})\)
Expand:
\(S = 2xy + \frac{16000}{y}+\frac{16000}{x}\)
\(S = 2xy + 16000(\frac{1}{y}+\frac{1}{x})\)
Differentiate S w.r.t x
\(\frac{dS}{dx} = 2y - \frac{16000}{x^2}\)
Differentiate S w.r.t y
\(\frac{dS}{dy} = 2x - \frac{16000}{y^2}\)
Equate both differentiation to 0
\(2x - \frac{16000}{y^2} = 0\)
Multiply through by \(y^2\)
\(2xy^2 - 16000 = 0\)
\(2xy^2 = 16000\)
Divide through by 2
\(xy^2 = 8000\) -- (1)
\(2y - \frac{16000}{x^2} = 0\)
Multiply through by x^2
\(2x^2y - 16000 = 0\)
\(2x^2y = 16000\)
Divide through by 2
\(x^2y = 8000\) --- (2)
Divide (1) by (2)
\(\frac{x^2y = 8000}{xy^2 = 8000}\)
\(\frac{x}{y} = 1\)
\(x = y\)
Substitute y for x in (1)
\(x^2y = 8000\)
\(x^2 * x = 8000\)
\(x^3 = 8000\)
Take cube roots
\(x =20\)
Hence;
\(x = y = 20\)
Recall that:
\(z = \frac{8000}{xy}\)
\(z = \frac{8000}{20 * 20}\)
\(z = 20\)
Hence, the dimension of the box that minimizes the surface area of the box is:
\(x = y = z = 20\)

Consider the given function,

The area covered by weed after 110 days is calculated as follows,

Length = \(18.5cm\)Area = \(259cm^{2}\) = l * b
Therefore, breadth = area / length
Breath = 259 / 185 = 1.4 * 10 = 14 cm
Perimeter = 2 * (l + b)Perimeter = 2 (18.5 + 14)
Perimeter = 2 (32.5)

The given values into the equation AE = 2a + 10. Therefore, The value of AE is 3 - x.
To find the value of AE, we can substitute the given values into the equation AE = 2a + 10.
Given:
AB = 10
AE = 2a + 10
ED = x + 3
CD = 4
Since AB is a segment on the line, it can be divided into AE and ED. Therefore, AB = AE + ED.
We know that AB = 10 and CD = 4. So, if we subtract CD from AB, we get AE + ED = 10 - 4.
AE + ED = 6.
Now, we can substitute the value of ED, which is x + 3, into the equation: AE + x + 3 = 6.
To find the value of AE, we need to isolate it on one side of the equation. Let's subtract x and 3 from both sides:
AE = 6 - x - 3.
Simplifying further, we get;
AE = 3 - x.
Therefore, the value of AE is 3 - x.
