The number of shots required for the archer to hit the target with at least 80% probability is 7 shots.

1. Given data:

  Probability of hitting the target in a single shot (p) = 0.2

  Desired probability of hitting the target (P) = 0.8

2. We can use the binomial distribution to calculate the probability of hitting the target after a certain number of shots.

The probability of hitting the target exactly k times out of n shots is given by the binomial probability formula: P(X = k) = C(n, k) * p^k * (1-p)^(n-k), where C(n, k) is the binomial coefficient.

3. To find the number of shots required, we need to calculate the cumulative probability of hitting the target for increasing values of n until it reaches at least 80%.

4. Start with n = 1 and calculate the cumulative probability:

  P(X ≤ 0) = (1-p)^1 = 0.8

5. Increase the number of shots by 1 and calculate the cumulative probability:

  P(X ≤ 1) = P(X = 0) + P(X = 1) = (1-p)^1 + C(1, 1) * p^1 * (1-p)^0

6. Continue this process until the cumulative probability reaches at least 0.8.

7. By calculating the cumulative probabilities for increasing values of n, we find that the archer needs to take at least 7 shots to hit the target with at least 80% probability.

8. Interpretation:

  With at least 7 shots, the archer has an 80% or higher probability of hitting the target. This means that in the majority of cases, the archer will hit the target after 7 or more shots.

One of the areas of Statistical Methods is forecasting (making future predictions), which also includes computing regressions and determining the theoretical validity.

Naive forecasting, which repeats the present datum into future periods, is one of the statistical methods used in predicting. It can be used to generate sample predictions, after which one can compare other methods' results.

Methods-

Moving Average

Exponential Smoothing

Autoregressive Moving Average

Therefore, since it doesn't provide an exact model, this applies to time series where all that is required is some basic data.

Answer:

Solution,

Onions less than 60 grams = 2 --> Pickling

Onions greater than 120 grams = 5 + 3 = 8 --> Market

Onions between 60 and 120 = 13---> Processing

Total frequency = 2 + 8 + 13 = 23

Now,

\(x = \frac{13}{23} \times 360\)

\(x = 203.48\)

\(x = 203.5\)

Hope this helps ..

Good luck on your assignment...

Answer:

x=190°

Step-by-step explanation:

find the frequency of the given numbers dividing by their numbers

onions less than 60g=(2+2/2)=²/9

onions greater than 120g=(5+3/2)= 4 (4+3/2). =3.5/9

To convert into degrees so that they can fit in the bar graph multiply the frequencies by 360 that is:

picking=²/9×360=80°

market=3.5/9×360=90°

x=360°-90°-80°

x=190°

confirmation

pie chart° add up to 360°

picking=80°

market=90°

x=190°

190°+80°+90°=360°

The domain and range of the graph of a logarithmic function are;

The basic equation of a logarithmic function can be presented in the form;

\(y = log_{b}(x) \)

Where;

b > 0, and b ≠ 1, given that we have;

\(y = log_{1}(x)\)

\( {1}^{y} = 1\)

The inverse of the logarithmic function is the exponential function presented as follows;

\(x = {b}^{y} \)

Given that b > 0, we have;

\( {b}^{y} = x > 0\)

Therefore, the graph of a logarithmic function has only positive x-values

The graph of a logarithmic function is one with a domain and range defined as follows;

Domain; 0 < x < +∞

Range; -∞ < y < +∞, which is the set of real numbers.

The correct option therefore has a domain as x > 0 and range as the set of all real numbers.

The probability of receiving two heads and one tail is 3/8, or 0.375.

One of the areas of probability theory is the estimation of the chance of experiments occurring. Using a probability, we can calculate everything from the likelihood of getting heads or tails when flipping a coin to the likelihood of making a research error, for example. It is essential to appreciate the most basic definitions of this branch, such as the formula for computing probabilities in equiprobable sample spaces, the likelihood of two events joining together, the probability of the complementary event, etc., in order to properly understand it .Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. Mathematics has incorporated probability to forecast the likelihood of various events.

The distance travelled before developing a flat tire illustrates multiplication of fractions

Horace rode a distance of \(\frac {9}{16} mile\) before having a flat tire

The parameters are given as:

\(Length=\frac 34\ mile\) ----- The length of the path

\(d=\frac 34\) ---- fraction of distance traveled before having a flat tire

So, the actual distance (D) travelled is:

\(D=d \times Length\)

Substitute values for d and Length

\(D= \frac 34 \times \frac 34\ mile\)

Multiply fractions

\(D= \frac {3 \times 3}{4 \times 4} mile\)

\(D= \frac {9}{16} mile\)

To find the derivative of y using logarithmic differentiation.

The formula to be used is given below,

\(dy/dx = y * (ln(dy/dx))\) ........(1)

Take natural logarithms of both sides of the given equation to get the following equation,

\(ln(y) = ln(3√x(x − 2)) + ln(x^2) + ln(1 + ln(x))\)

Differentiate with respect to x on both sides of the above equation and simplify,

\(1/y * dy/dx = 1/3√x(x − 2) * 3/2 (x-2) * (1/x) + 2/x + 1/x (1/1 + ln(x))\)

\(dy/dx = y * (1/y * dy/dx)\)

\(dy/dx = 3√x(x − 2) * x^2 * (1 + ln(x)) * (1/3√x(x − 2) * 3/2 (x-2) * (1/x) + 2/x + 1/x (1/1 + ln(x)))\)

Step-by-step explanation:

Answer:

a) \(\mathbf{ f(g(x))=x+2\sqrt{x} +1}\)

b) \(\mathbf{f(g(9))=16}\)

Step-by-step explanation:

We are given:

\(f(x)=(x-2)^2\\g(x)=\sqrt{x} +3\)

We need to find  \(a) f(g(x))\\b) f(g(9))\)

a) First finding: \(f(g(x))\)

It can be found by putting the value of g(x) into f(x)

We are given:

\(f(x)=(x-2)^2\\Put\:x=g(x)\:i.e. \: x= \sqrt{x} +3\\f(g(x))=(\sqrt{x} +3-2)^2\\Now\: solving:\\f(g(x))=(\sqrt{x} +1)^2\\Using\:formula\:\mathbf{(a+b)^2=a^2+2ab+b^2}\\f(g(x))=(\sqrt{x})^2+2(\sqrt{x} )(1)+(1)^2\\ f(g(x))=x+2\sqrt{x} +1\)

SO, we get: \(\mathbf{ f(g(x))=x+2\sqrt{x} +1}\)

b) Now finding: \(f(g(9))\)

It can be found by putting x=9 in f(g(x))

We have:

\(f(g(x))=x+2\sqrt{x} +1\\Put\:x=9\\f(g(9))=9+2\sqrt{9}+1\\We\:know\: \sqrt{9}=3\\ f(g(9))=9+2(3)+1\\f(g(9))=9+6+1\\f(g(9))=16\)

So, we get: \(\mathbf{f(g(9))=16}\)

Actaul Area of a parallelogram (A) = Actual Base(b)× actual heigth(h)

A = bh.......................... Equation 1

From the question,

If each 6 in on the scale drawing equals 3 feet

Given:

base on the scale drawing = 8 in.

Actual base(b) = (8×3)/6 = 4 feet.

Height on the scale drawing = 16 in

Actual height(h) = (16×3)/6 = 8 feet.

Substitute these values into equation 1

Thee factory is able to provide 94.38 boxes per hour to the warehouse.

Rate = (2000 - 1245) / 8 = 94.38 boxes per hour

Therefore, the factory is able to provide 94.38 boxes per hour to the warehouse.

Boxes added in 40 hours = rate * time = 94.38 * 40 = 3,775.2

Therefore, the inventory at the end of a 40-hour work week would be:

1245 + 3775.2 = 5020.2 boxes

rate = (50000 - 1245) / time

Simplifying this equation, we get:

time = (50000 - 1245) / rate = 511.64 hours (rounded to two decimal places).

Therefore, it will take approximately 511.64 hours to fill the warehouse to its 50,000 box capacity,
