Answer:

[tex]\frac{1}{8}[/tex]

Step-by-step explanation:

P(Black) = [tex]\frac{1}{2}[/tex]

[tex]\frac{1}{2}*\frac{1}{2}*\frac{1}{2}=\frac{1}{8}[/tex]

P(Black 3/3) = [tex]\frac{1}{8}[/tex]

The probability it will land on the black all three times out of three spins is 1/8.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given the probability of the spinner landing on black is 1/2. Therefore, the probability it will land on the black all three times out of three spins is,

Probability = (1/2) × (1/2) × (1/2) = 1/8

Hence,  the probability it will land on the black all three times out of three spins is 1/8.

Final answer:

To find the amount Carl and Linda Munson will have accumulated in 10 years, you can use the formula for compound interest. Plugging in the given values, their 401k retirement account will have approximately $3,639.48 after 10 years.

Explanation:

To find the amount Carl and Linda Munson will have accumulated in 10 years, we can use the formula for compound interest:

A = P(1+r)^n

Where:

A = amount accumulated after n years

P = principal amount

r = interest rate (in decimal form)

n = number of years

Using the given information, P = $2,100, r = 8% (or 0.08), and n = 10. Plugging these values into the formula:

A = $2,100(1+0.08)^10

Simplifying the expression:

A = $2,100(1.08)^10

Calculating the value:

A ≈ $3,639.48

Therefore, Carl and Linda Munson will have approximately $3,639.48 accumulated in their 401k retirement account after 10 years.

For this case we have that by definition, the total surface area of a right prism is given by:[tex]SA = ph + 2B[/tex]

The side across angle 18 is the opposite side. The perpendicular angle that touches the same line is adjacent. To figure out the length of JL, we need to use the measurement 34.6 mm (hypotenuse). So in this equation we will use hypotenuse to find opposite. Hypotenuse and opposite result in Sin on the calculator. So on the calculator, you would find the Sin of 18 and then multiply that number by 34.6. The answer would then be 10.7 (rounded).

Answer: 10.7 mm (rounded)

Answer:

JL ≈ 10.7 mm

Step-by-step explanation:

Using the sine ratio in the right triangle

sin18° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{JL}{34.6}[/tex]

Multiply both sides by 34.6

34.6 × sin18° = JL, hence

JL ≈ 10.7 ( to 1 dec. place )

both option (A) & (B) is description of given distribution.

Step-by-step explanation:

The outlier is a point which lies differently or far away from rest points in datasets or distribution.

Here we can self-time for one apple on the 10th day is outlier present in the distribution. Thus Option (A) is correct.

We divide the heterogeneous group into many homogeneous groups, these homogeneous group is known as Cluster. It can be seen naturally.

Also, here distribution is divided into many clusters and we can see given distribution has many clusters and one of them is from 4 to 6 days. Thus Option (B) is also a correct option here.

here are my analyses of the possible answer choices based on the image you sent:  The distribution clusters around 4-6 days and has a few potential outliers above 8 days.

here are my analyses of the possible answer choices based on the image you sent:

(A) The distribution has an outlier.

There are a few data points that are higher than the rest of the distribution, so in that sense, yes, there are outliers. However, it is important to consider what an outlier is in the context of the data. If the data is normally distributed, then outliers are data points that fall more than two standard deviations away from the mean. In this case, it is difficult to say for sure whether the data is normally distributed, so it is also difficult to say for sure whether there are outliers. However, there are a few data points that are higher than the rest of the distribution.

(B) The distribution has a cluster from 4 to 6 days.

There is a cluster of data points from 4 to 6 days, so yes, this statement is accurate.

In conclusion, the accurate descriptions of the distribution are:

Answer:

Step-by-step explanation:

The cosine of angle Ф is √(1 - sin²Ф), which is positive if our angle 81 degrees is in Quadrant I.

sin 81° = 0.9877, so (sin 81°)² = 0.9755, and

cos 81° = 1 - 0.9755 = 0.0245

To find the cosine of 81 degrees in terms of sine, we use the identity cos(Ф) = sin(90° - Ф), giving us cos(81°) = sin(9°).

To find the cosine of 81 degrees in terms of sine, we use the trigonometric identity that relates sine and cosine for complementary angles. The cosine of 81 degrees is the same as the sine of 9 degrees, because 81 and 9 add up to 90 degrees. The trigonometric identity is cos(Ф) = sin(90° - Ф).

Using this identity:

cos(81°) = sin(90° - 81°)

= sin(9°).

Therefore, the cosine of 81 degrees is equal to the sine of 9 degrees.

Answer: X = 2.4

Step-by-step explanation:

The first step should be to isolate x or get x alone. This means we should get rid of the divided by 2 on the left by multiplying both sides by 2. This would get us to 2 * X/2 = 1.2 * 2. The multiplying X/2 would simplify to just X, and the 1.2 * 2 = 2.4. Therefore the final equation would become X = 2.4.

To check, you would plug in 2.4 into where X is in X/2 = 1.2. Since 2.4/2 = 1.2, we know that X = 1.2 from checking.

x = 2.4

You want to get x by itself, so you need to get rid of the division on the left side of the equals sign. The way to undo division is to multiply. So, multiply both sides of the equation by 2. This gives you x = 2.4, so now you have your answer.

Now, since the problem wants us to check our answer, we just put 2.4 back into the equation as x. This gives us 2.4 / 2 = 1.2. Now, we just simplify to see if the equation is true. If it is true, the answer is correct. 2.4 divided by 2 is 1.2, so 1.2 = 1.2, which means our answer is correct.

Answer:

If the number of miles is 6

Step-by-step explanation:

Since they vary with different rates ($/mile in our case), such equality can only be true for a specific amount of miles.  Less miles and the left part ($2.50...) would be higher, more miles and the right part ($1.00...) would be higher because it grows faster.

So, that's the number of miles for which the equation is true?

2.50 + 0.50m = 1.00 + 0.75m

Let's regroup similar terms:

1.50 = 0.25m

the isolate m

m = 6

So, if the ride covers 6 miles, the equation is true:

2.5 + 0.5 (6) = 1.00 + 0.75 (6)

2.5 + 3 = 1 + 4.50

5.5 = 5.5

Answer:

One cab charges an initial fee of $2.50 and then $0.50 for every mile. The other cab company charges an initial fee of $1.00 and then $0.75 for every mile.

Answer:

Potential roots:  [tex]\frac{9}{4},\frac{9}{2},9,\frac{3}{4},\frac{3}{2},3, \frac{1}{4},\frac{1}{2},1[/tex]

Step-by-step explanation:

Simply put, the rational roots theorem tells us that if there are any rational roots of a polynomial function, they must be in the form

±  [tex]\frac{FactorsOfa_{0}}{FactorsOfa_n}[/tex]

Where

a_n is the number before the highest power of the polynomial, and

a_0 is the constant in the polynomial

From the polynomial shown, we have a_n = 9 and a_0 = 4

The factors of 9 are 9, 3, 1

and

The factors of 4 are 4,2,1

So, if there are any rational roots, they would be:

±  [tex]\frac{FactorsOfa_{0}}{FactorsOfa_n}[/tex]

±  [tex]\frac{9,3,1}{4,2,1}[/tex]

Which is  ±   9/4, 9/2, 9/1, 3/4, 3/2, 3/1, 1/4, 1/2, 1/1

or

[tex]\frac{9}{4},\frac{9}{2},9,\frac{3}{4},\frac{3}{2},3, \frac{1}{4},\frac{1}{2},1[/tex]

Using the Rational Root Theorem, the polynomial f(x) = 9x^4 - 2x^2 - 3x + 4 has potential rational roots which are ±4, ±2, ±1, and their counterparts divided by 3. In the complex number system, every nth-order polynomial can be factored into n roots, including imaginary roots for equations that lack real solutions.

Rational Root Theorem and Potential Roots

The Rational Root Theorem is a useful tool for identifying all potential rational roots of a polynomial equation. When applying this theorem to the given polynomial f(x) = 9x^4 - 2x^2 - 3x + 4, we note that the potential rational roots are the divisors of the constant term (in this case, 4) divided by the divisors of the leading coefficient (in this case, 9). Therefore, the potential roots are ±4, ±2, ±1, and their counterparts divided by 3, which are ±4/3, ±2/3, and ±1/3. To determine which of these are actual roots, each must be tested in the polynomial equation.

The concept of complex number system further elaborates on polynomials by stating that every nth-order polynomial can have up to n roots, factored into linear factors in accordance with the fundamental theorem of algebra. In the case of second-order polynomials, the real number system may not yield roots for equations like x² + 1, but in the complex number system, such polynomials do have roots and can be factored as (x - i)(x + i), for instance.

The only trinomial among the four expressions is x^6 −x+ √6 .

A trinomial is an algebraic expression with three terms, each containing a power of the variable raised to a non-negative integer and multiplied by a coefficient.

Let's analyze each expression:

x^3 + x^2 - √x: This has three terms (x^3, x^2, and -√x), but √x contains a fractional exponent, which is not allowed in a polynomial (and therefore, a trinomial). So, it's not a trinomial.

2x^3 - x^2: This has two terms (2x^3 and -x^2), not three. Therefore, it's not a trinomial.

4x^3 + x^2 - 1/x: This has three terms (4x^3, x^2, and -1/x), but 1/x is equivalent to x^-1, which is a negative exponent.

Similarly to option 1, this violates the non-negative integer exponent requirement for polynomials. So, it's not a trinomial.

x^6 - x + √6: This has three terms (x^6, -x, and √6). Note that √6 does not contain a variable and can be considered a constant, satisfying the polynomial and trinomial requirements. Therefore, this is a trinomial.

In, the only trinomial among the given options is: 4. x^6 - x + √6 .

A trinomial is an algebraic expression consisting of three terms. Let's examine each option:

Step-by-step explanation:

The measure of arc CB is 236°.

find the measure of the indicated arc in circle O.

Given information:

-[tex]\(m\angle DOC = 44°\)[/tex]

- [tex]\(m\angle COB = 80°\)[/tex]

We want to find the measure of arc CB.

1. Calculate the central angle containing arc CB:

  - The sum of the central angles [tex]\(m\angle DOC\) and \(m\angle COB\)[/tex]gives the measure of the entire circle.

  - Total degrees in a circle = 360°

  - Central angle containing arc CB = [tex]\(m\angle DOC + m\angle COB\)[/tex]

   [tex]\[m\angle DOC + m\angle COB = 44° + 80° = 124°\][/tex]

2. Find the measure of arc CB:

  - Subtract the central angle from 360° to get the measure of arc CB.

[tex]\[m\text{ arc CB} = 360° - 124° = 236°\][/tex]

Therefore, the measure of arc CB is 236°.
