a. The probability of exactly two thefts occurring in a minute is approximately 0.139.

b. The probability of no thefts occurring in a minute is approximately 0.026.

c. The probability of three or fewer thefts occurring in a minute is approximately 0.398.

a. The probability of exactly two thefts occurring in a minute can be calculated using the Poisson probability distribution. With an average rate of 3.6 thefts per minute, the probability is given by:

P(X = 2) = (e^(-λ) * λ^2) / 2!

where λ is the average rate of thefts per minute.

Plugging in the values, we have:

P(X = 2) = (e^(-3.6) * 3.6^2) / 2! ≈ 0.139

Therefore, the probability of exactly two thefts occurring in a minute is approximately 0.139.

b. The probability of no thefts occurring in a minute can be calculated using the Poisson probability distribution as well. The formula is:

P(X = 0) = e^(-λ)

Substituting the average rate of thefts per minute

P(X = 0) = e^(-3.6) ≈ 0.026

Thus, the probability of no thefts occurring in a minute is approximately 0.026.

c. The probability of three or fewer thefts occurring in a minute can be calculated by summing the probabilities of having 0, 1, 2, and 3 thefts. Using the Poisson probability distribution, we can calculate each individual probability and sum them up:

P(X ≤ 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)

Substituting the values, we get:

P(X ≤ 3) ≈ 0.026 + 0.094 + 0.139 + P(X = 3)

We can calculate P(X = 3) using the Poisson formula as before:

P(X = 3) = (e^(-3.6) * 3.6^3) / 3!

Substituting the value:

P(X = 3) ≈ 0.139

Therefore:

P(X ≤ 3) ≈ 0.026 + 0.094 + 0.139 + 0.139 ≈ 0.398

Hence, the probability of three or fewer thefts occurring in a minute is approximately 0.398.

The probability of the next elk caught being unmarked is 0.96 when the total number of elks is 5625 and the number of elks marked is 225.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Total number of elks = 5625

Number of elks marked = 225

We need to find the total number of elks not marked or  unmarked we can find it by,

= 5625 - 225

= 5500

Therefore, the total number of elks unmarked is 5500.

We can determine determined the likelihood of the next elk caught being unmarked by using probability. The probability is given by:

P.S. thanks to Piinoy for the awesome answer.

Answer:

x  −  y  =  − 3

Step-by-step explanation:

The standard form of a linear equation is Ax + By = C

It is most of the time also stated that A must be positive and A, B, and C should all be integers.

y = x + 3

you can subtract x from both sides, so you get:

y - x = x - x + 3

y - x = 3

This is sometimes regarded as the standard form, but most of the time, you need to make sure that A is positive, and it is currently -1. How can we change a negative number to a positive number: we multiply by -1. Also, whatever you do at the left part, you must also do at the right part:

-1 . (y - x) = -1 . 3

-y + x = -3

After some reordering you get:

x - y = -3

The requried solutions with the help of the quadratic formula have been shown.

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression.

Here,
1.
To solve the equation x² + 2x - 3 = 0 using the quadratic formula, we'll first identify the coefficients:

a = 1
b = 2
c = -3

Now we can plug these values into the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

x = (-2 ± √(2² - 4(1)(-3))) / 2(1)

x = (-2 ± √(16)) / 2

x = (-2 ± 4) / 2

This gives us two possible solutions:

x₁ = (-2 + 4) / 2 = 1

x₂ = (-2 - 4) / 2 = -3

Therefore, the solution set is {least: -3, greatest: 1}.

Similarly,
2. the solution set is {least: 3 - √(5), greatest: 3 + √(5)}.

Answer:

AC is greater than BC because segment AC is the hypotenuse of right triangle ABC, and the hypotenuse is the longest side of a right triangle.

The hypotenuse is the longest side of the triangle. Side AC of the triangle is its hypotenuse, thus greater than BC (segment and angle theorem of a triangle).

A triangle is a shape with three side and angles. Its longest side is referred to as hypotenuse. And this side is usually opposite to the greatest angle. Examples of triangle include: equilateral, isosceles, acute, right angles, obtuse angle etc.

The given question shows that triangle ACB is a right angled triangle. This is because <CBY = \(90^{o}\).

So that;

<CBY + <CBA = \(180^{o}\)

Now comparing side AC with BC:

The segment and angle theorem of a triangle states that: the longest side of a triangle is always opposite to the greatest angle.

Thus, since <CBA is the greatest of the angles here, then AC is the longest side.

Therefore, the side AC is the hypotenuse of the triangle and it is greater than BC.

Zeroes: x = 4, x = -6

The vertex is at ( -1 , 50 )

Step-by-step explanation:

I'll do the first one, you try the rest

All of these are written in y = a(x - x1)(x - x2) where x1 and x2 are given and x are the two different zeroes (or x-intercepts)

f(x) = -2(x-4)(x+6)

The zeroes are x - 4 = 0 and x + 6 = 0 if you solve, you get 4 and -6

Zeroes: x = 4, x = -6

The x value of the vertex can be found using -b/2a (in the form ax^2 + bx + c)

First expand f(x)

-2(x^2 + 2x - 24) => -2x^2 - 4x + 48

b = -4 and a = -2

-(-4)/2(-2) = 4/-4 = -1

the x-value of the vertex is -1

Now substitute -1 as x to find the y-value of the vertex

-2(-1-4)(-1+6) = -2(-5)(5) = 50 <= y-value of vertex

The vertex is at ( -1 , 50 )

the two lines are parallel, the angle they make should be equal and one angle is common so the triangles are similar by AAA.

Now the ratio of sides are \( \frac{20+8}{20}=\frac{x+18}{x}\)

use divideno, \(\frac8{20}=\frac{18}x\)

and then inverse the whole equation to get \(x=20\times\frac{18}{8} \implies x= 45\)

Answer:

\(\Large \boxed{\mathrm{B) \ 45}}\)

Step-by-step explanation:

We can solve the problem using ratios.

\(\displaystyle \frac{x}{20} =\frac{x+18}{20+8}\)

Cross multiply.

\(20(x+18)=x(20+8)\)

Expand brackets.

\(20x+360=28x\)

Subtract 20x from both sides.

\(360=8x\)

Divide both sides by 8.

\(45=x\)
