The probability of seeing the word "math" in a 10-letter string typed by a monkey is 0.0024 (or 0.24%).

To calculate this probability, we first need to determine the total number of possible 10-letter strings that the monkey can type. Since the monkey never repeats letters, the number of possible 10-letter strings is given by the permutation formula:

10P10 = 10!/(10-10)! = 3,628,800

Next, we need to determine the number of 10-letter strings that contain the word "math". We can do this by fixing the position of the "m" and the "a", and then allowing the monkey to freely choose the remaining 6 letters. The number of ways to do this is given by:

8P6 = 8!/(8-6)! = 56

Finally, we divide the number of 10-letter strings containing "math" by the total number of possible 10-letter strings to obtain the probability:

56/3,628,800 = 0.000024 = 0.0024 (or 0.24%)

The measure of the arc intercepted by the chord and tangent is 180° - 2x°.

What is the point of tangency?

The point of tangency is the point where a tangent line intersects a curve or surface. In geometry, a tangent line is a straight line that touches a curve or surface at a single point, without crossing it at that point. The point of tangency is the point where the tangent line touches the curve or surface.

If a chord and a tangent form an angle of x° at the point of tangency, then the angle between the chord and the tangent (which is formed by extending the chord) is also x°.

This is because the tangent is perpendicular to the radius at the point of tangency, and the chord intersects the radius at that same point.

The arc intercepted by the chord and tangent is the arc between the endpoints of the chord.

To find the measure of this arc, we need to know the angle at the center of the circle that subtends this arc.

Since the chord and tangent form an angle of x°, we know that the angle between the tangent and the radius that passes through the point of tangency is 90° - x° (since the angle between a tangent and a radius is always 90°).

We can use this fact to find the angle at the center of the circle that subtends the arc intercepted by the chord and tangent.

Let y° be the measure of the angle at the center of the circle that subtends the arc intercepted by the chord and tangent. Then we have:

y° = 2(90° - x°)

The factor of 2 comes from the fact that the chord and tangent divide the circle into two equal arcs, and we want the measure of the arc intercepted by just one of these arcs.

Simplifying this expression, we get:

y° = 180° - 2x°

Therefore, the measure of the arc intercepted by the chord and tangent is 180° - 2x°.

An equation of a line that is parallel to the line y=-5x-8 and passes through the point (7, -2) is y = -5x + 33.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical expression:

y - y₁ = m(x - x₁)

Where:

Since the line is parallel to y=-5x-8, the slope is equal to -5.

At data point (7, -2) and a slope of -5, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - (-2) = -5(x - 7)

The equation of the line that is parallel to y = -5x - 8 and passes through the point (7,-2) is y = -5x + 33, in slope intercept form.

To find an equation that is parallel to the line y = -5x - 8, we know that it must have the same slope. So the slope of the new line is -5.

Now we use the point-slope form of a linear equation to find the equation of the line passing through (7,-2) with slope -5:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is the given point.

Substituting the values we get:

y - (-2) = -5(x - 7)

Simplifying and solving for y, we get:

y + 2 = -5x + 35

y = -5x + 33

Therefore, the equation of the line that is parallel to y = -5x - 8 and passes through the point (7,-2) is y = -5x + 33, in slope intercept form.

Polynomials are expressions that have multiple terms.

Breaking Apart Polynomials

When multiplying by a polynomial, we can break apart one of the polynomials, and multiply by each term individually. This means to multiply 3x² + x - 1 by 4x + 5, we can break apart the binomial into its separate terms. Instead of trying to multiply everything at once, we can multiply the trinomial by 4x and then multiply the trinomial by 5. Finally, add together the 2 products for the final answer.

Multiplying Polynomials

First, let's multiply the trinomial by 4x.

To find the product, multiply each term of the trinomial by 4x, then add them back together.

So, the first product is 12x³ + 4x²- 4x. Next, let's multiply 5(3x² + x - 1) the same way.

This means that the second product is 15x² + 5x - 5. Finally, let's add the 2 products together.

Then, simplify the expression.

This gives us our final answer. The product of 3x² + x - 1 and 4x + 5 is 12x³ + 19x² + x - 5.

Answer:

The hour marks on a clock face are evenly spaced, 30° apart. To find the angle a line from the four o'clock mark to the twelve o'clock mark makes with a horizontal line, we need to count the number of hour marks between the two positions and multiply by 30°.

Starting from the four o'clock mark and moving clockwise to the twelve o'clock mark, we count 8 hour marks, including the one at the twelve o'clock mark. Multiplying 8 by 30°, we get:

8 x 30° = 240°

Therefore, the angle between the line from the four o'clock mark to the twelve o'clock mark and a horizontal line is 240°.

Approximately 0.357 or 35.7% of customers require more than 12 minutes to check out.

Since the checkout times are exponentially distributed with a mean of 5.5 minutes, we can use the exponential distribution formula to find the probability that a customer will take more than 12 minutes to check out:

P(X > 12) = 1 - P(X ≤ 12)

where X is the checkout time.

To find P(X ≤ 12), we can use the cumulative distribution function (CDF) of the exponential distribution, which is:

F(x) = 1 - e^(-λx)

where λ is the rate parameter of the distribution. For an exponential distribution with mean μ, the rate parameter λ is equal to 1/μ.

So, in our case, λ = 1/5.5 = 0.1818, and we can calculate P(X ≤ 12) as:

P(X ≤ 12) = F(12) = 1 - e^(-0.1818 × 12) ≈ 0.643

Therefore, the probability that a customer will take more than 12 minutes to check out is:

P(X > 12) = 1 - P(X ≤ 12) ≈ 1 - 0.643 ≈ 0.357

A measurable quantity that may vary, is subject to change, and can be controlled is known as a variable.

Variables play an essential role in scientific experiments, mathematical expressions, and real-life scenarios. They can be classified into two main categories: independent and dependent variables.
Independent Variable:

This type of variable is the one that is manipulated or controlled by the experimenter.

It is often the cause or the factor being tested in an experiment, and its effects on other factors are observed. For example, in a plant growth experiment, the amount of sunlight a plant receives could be an independent variable.
Dependent Variable:

The dependent variable is the outcome or result that is being measured in response to changes in the independent variable. It is dependent on the independent variable and shows the effect of the manipulation.

In the plant growth example, the height of the plant would be the dependent variable.
To summarize, a variable is a measurable quantity that may vary or change and can be controlled.

Variables are essential for understanding and analyzing relationships between different factors in experiments, mathematics, and everyday life.

By manipulating independent variables and observing their effects on dependent variables, we can explore cause-and-effect relationships and make predictions about various phenomena.

Answer: 39°

Step-by-step explanation:

In an isosceles triangle, two sides are of equal length, and the angles opposite these equal sides are also equal. Let's call these two equal angles x. Given that one angle measures 102°, we can find the possible measures for the other two angles.

The sum of the interior angles of a triangle is always 180°. So, we have:

x + x + 102° = 180°

2x = 180° - 102°

2x = 78°

x = 39°

Therefore, the other two angles in the isosceles triangle are both 39°.

The value of AC to the nearest tenth is 29.5

The sine rule states that if a, b and c are the lengths of the sides of a triangle, and A, B and C are the angles in the triangle; with A opposite a, etc., then a/sinA=b/sinB=c/sinC.

Angle B = 180-(33+58)

= 180-91 = 89°

represent AC by x

x/ sin89 = 25/sin 58

xsin58 = 25sin89

0.848x = 0.9998×25

0.848x = 24.995

the measure of the smallest angle of ΔDEF is approximately 41.41°.

How to solve the question?

In ΔDEF, DM is a median and M is on EF. Additionally, DM = EF, and DL is an angle bisector of ∠EDF, L is on EF, and m∠DLF = 64°. We need to find the measure of the smallest angle of ΔDEF.

Since DM is a median, it divides EF into two equal parts, EM and MF. Thus, EM = MF = DM/2 = EF/2.

Let x be the measure of ∠EDF. Then, we know that ∠EDM = ∠FDM = 90° because DM is a median.

Using the angle bisector theorem, we know that DL/EL = DF/EF. Since DL is an angle bisector, we also know that ∠DLE = ∠ELF = x/2. Therefore, we have:

DL/EL = DF/EF

DL/(EF/2) = DF/EF

DL = DF/2

Now, we can use the Law of Cosines in ΔDEF to find DF in terms of x:

DF² = DE² + EF² - 2(DE)(EF)cos(x)

DF² = DM² + MF² - 2(DM)(MF)cos(x)

DF² = (EF)²/4 + (EF)²/4 - (EF)²cos(x)

DF² = (EF)²/2 - (EF)²cos(x)

Since DL = DF/2, we have:

DL² = (EF)²/8 - (EF)²cos(x)/4

Using the angle bisector theorem again, we know that EL/FL = DE/DF. Since DL = DF/2, we also know that FL = EF - DL = EF/2. Therefore, we have:

EL/EF - EL/2 = DE/DF

EL/EF - EL/(2DL) = DE/DF

EL/EF - EL/(EF/4) = DE/DF

EL = EF(DE/DF)/3

Now, we can use the Law of Cosines again in ΔDEL to find DE in terms of x:

DE² = DL²+ EL² - 2(DL)(EL)cos(x/2)

DE² = (EF)²/8 - (EF)^2cos(x)/4 + [EF(DE/DF)/3]² - 2(DL)(EF(DE/DF)/3)cos(x/2)

DE² = (EF)²/8 - (EF)^2cos(x)/4 + (EF)²(DE/DF)^2/9 - (EF)(DE/DF)(EF/6)cos(x/2)

Since DM = EF, we have DE = DM - EM = EF/2 - EF/4 = EF/4. Thus, we can substitute this into the equation above and simplify:

(EF/4)²= (EF)²/8 - (EF)^2cos(x)/4 + (EF)^2(DE/DF)²/9 - (EF)(DE/DF)(EF/6)cos(x/2)

(EF)²/16 = (EF)²/8 - (EF)²cos(x)/4 + (EF)²(DE/DF)²/9 - (EF)(DE/DF)(EF/6)cos(x/2)

0 = (EF)²/72 - (EF)²cos(x)/4 + (EF)²(DE/DF)²/9 - (EF)(DE/DF)(EF/6)cos(x/2)

Now, we can substitute DL = DF/2 = (EF/4)/2 = EF/8 and EL = EF(DE/DF)/3 = EF(DE)/(3EF/4) = 4DE/3 into the equation above and simplify:

0 = (EF)²/72 - (EF)²cos(x)/4 + (EF)²(DE/DF)²/9 - (EF)(DE/DF)(EF/6)cos(x/2)

0 = (EF)²/72 - (EF)²cos(x)/4 + (EF)^2(DE/DF)²/9 - (EF/8)(4DE/3)(EF/6)cos(x/2)

0 = (EF)²/72 - (EF)²cos(x)/4 + (EF)²(DE/DF)²/9 - (EF²/72)cos(x/2)

0 = (EF)²/72 - (EF)²cos(x)/4 + (EF)²(DE/DF)²/9 - (EF)²cos(x/2)/18

Simplifying this equation, we get:

cos(x)/4 - cos(x/2)/18 = (EF)²/72 - (EF)²(DE/DF)²/9

Now, we can substitute DE = EF/4 and DF = EF/2 into the equation above and simplify:

cos(x)/4 - cos(x/2)/18 = (EF)²/72 - (EF)²/144

cos(x)/4 - cos(x/2)/18 = (EF)²/144

We know that cos(x) is negative because x is the measure of the smallest angle of ΔDEF, so we can take the absolute value of both sides of the equation:

|cos(x)/4 - cos(x/2)/18| = (EF)²/144

Since 0° < x < 180°, we know that cos(x/2) > cos(x), so we can simplify further:

cos(x/2)/18 - cos(x)/4 = (EF)²/144

Now, we can substitute the given value of ∠DLF = 64° into the equation above and solve for EF:

cos(32°)/18 - cos(128°)/4 = (EF)^2/144

0.0289 - (-0.2113) = (EF)²/144

0.2402 = (EF)²/144

EF = √(0.2402*144)

EF ≈ 4.8044

Finally, we can use the Law of Cosines in ΔDEF to find x:

cos(x) = (DE² + EF² - DF²)/(2(DE)(EF))

cos(x) = (EF²/16 + EF² - EF²/4)/(2(EF/4)(EF))

cos(x) = 3/4

x = arccos(3/4)

x ≈ 41.41°

Therefore, the measure of the smallest angle of ΔDEF is approximately 41.41°.
