The probability that a dart hits one of the shaded areas is 1/6 when a dart is thrown at a regular hexagon dartboard with the design shown.

The area of mathematics known as probability studies potential outcomes of events as well as their relative probabilities and distributions.

Here,

angle of hexagon=360/6=60°

using trigonometric ratios,

area of triangle=bh/2

=(h*h√3/2)/2

=h²√3/4

area of hexagon=6*area of triangle

=6*(h²√3/4)

=3√3*h²/2

area of rectangle=bh

=h*h√3

=h²√3

area of shaded region,

=3√3*h²/2-h²√3

=h²√3/2

area of 1 shaded region=(h²√3/2)/2

=h²√3/4

Probability of hitting one shaded area,

=(h²√3/4)/(h²3√3/2)

=1/6

When a dart is thrown at a standard hexagonal dartboard with the pattern shown, the likelihood that it will land in one of the shaded areas is 1/6.

Drake needs 144 ft² (squared feet) of fabric to make the 8 ft long and 18 ft tall sail.

The area (square units) of two lengths is the product of the multiplication of the two lengths.

The area refers to the space occupied by a two-dimensional object or structure.

Areas are stated in square feet to show the squared units occupied by such objects.

The length of a sail = 8 feet

The height of the sail = 18 feet

The square area = 144 ft² (8 x 18)

Thus, Drakes requires a fabric measuring 144 ft² (squared feet) to make the sail.

Answer:

  B.) 4x^2 - 15x - 54

Step-by-step explanation:

You want the product f(x)·g(x) when f(x) = 4x+9 and g(x) = x-6.

The distributive property can be used to find the product. Each term of one binomial is multiplied by every term of the other, and like terms are combined.

  f(x)·g(x) = (4x +9)·(x -6)

  = 4x(x -6) +9(x -6)

  = 4x² -24x +9x -54 = 4x² +(-24 +9)x -54

  f(x)·g(x) = 4x² -15x -54 . . . . . . . . . . matches choice B

Additional comment

The product of two binomials is sometimes described using the mnemonic FOIL, for First, Outer, Inner, Last. These refer to the locations of the terms involved in the four products

These products are the same as the ones we show above.

The FOIL mnemonic is only helpful for two binomials. Any polynomials can be multiplied using the distributive property.

Answer:

slope = 10

Step-by-step explanation:

Solve the equation for "y". In other words, isolate "y":

y + 7 = 10(x - 4)

y = 10(x - 4) - 7

y = 10x - 40 - 7

y = 10x - 47

Above is a linear expression in slope-intercept form "y = mx + b", where "m=slope" and "b=y-intercept". "m=10", so 10 is the slope

Answer:Here's the basic equation

m(d) = 10d + 20(d - 2)  (the money total is the 10 dollar bills plus the 20 dollar bills (which are two less than the 10 dollars))

Step-by-step explanation:

To simplify it, start by distributing the 20:

m(d) = 10d + 20d - 40

add like terms

m(d) = 30d - 40

Answer:

Subtract 3 3/4 from 10 1/2.  Note that the LCD is 4, so 10 1/2 = 10 2/4.

Answer:

Bottom left

Step-by-step explanation:

Let's look at it as (1/3)^x first. This function would have a y-intercept of (0,1) (because (1/3)^0 is 1), and would then become (1/3) times smaller for every 1 unit increment of x. This would look like the top left graph in these options. However, we are given (1/3)^-x, which means, in terms of transformations, that the graph is flipped across the y-axis. Algebraically, this looks like (1/3)^(-x) which equals to  [tex]\frac{1}{(1/3)^x}[/tex], which simplifies down to 3^x, which would look like the bottom left graph.

Standard deviation for the given set of data { 6,7,8,9,10} is equal to √2.

As given in the question,

Given set of data is equal to :

{ 6,7,8,9,10}

[tex]x_{i}[/tex] = { 6,7,8,9,10}

Here total number of observation 'N' is equal to 5.

Mean [tex]\bar{x}[/tex] = ∑x / n

            = ( 6+ 7+ 8 + 9 + 10 ) / 5

            = 40 /5

            = 8

[tex]\sum (x_{i} -\bar{x})^{2}[/tex] = ( 6- 8)² + (7-8)² + (8 - 8)²+ ( 9 -8)² + (10 - 8)²

                 = 4 + 1+ 0 + 1+ 4

                 = 10

Standard deviation = [tex]\sqrt{ \frac{\sum (x_{i} -\bar{x})^{2}}{N}[/tex]

                                = √10/5

                                = √2

Therefore, standard deviation for the given set of data { 6,7,8,9,10} is equal to √2.

FALSE, there is no such thing as one sided in chi-square goodness of fit test.

b. The chi-square test statistic follows a Poisson null distribution.

FALSE, chi square is a distribution of its own more like normal distribution.

c. It compares an observed frequency distribution with an expected frequency distribution.

TRUE, because this is what is done in chi-square test.

d. The null hypothesis is that there is no difference between the observed and expected values.

TRUE

e. The degrees of freedom are k - 1, where k is the number of classes.

FALSE, because k is the number of parameters and not the number of classes.

The height of each of the two students is 64

The mean (aka the arithmetic mean, different from the geometric mean) of a dataset is the sum of all values divided by the total number of values. It’s the most commonly used measure of central tendency and is often referred to as the “average.”

Let the heights of each of the two students be x,

so that x, x, 68 and 62 are the heights of the four students

Average height which is 64.5 = [tex]\frac{x + x + 62 + 68}{4}[/tex]

[tex]\frac{x + x + 62 + 68}{4}[/tex] = 64.5

by cross multiplying,

x + x + 62 + 68 = 4 x 64.5

2x + 130 = 258

collecting like terms,

2x = 258 - 130

2x = 128

x = 128/2

x = 64 inches

In conclusion the height of each of the 2 students with equal height is 64 inches.

By using the concept of confidence interval, it is obtained that

We are 95% confident that the interval 15.75 < μ < 28.25 contains the population mean commute time in minutes using public transportation.

Second option is correct

What is Confidence interval?

Let the quantity which is to be estimated is [tex]\theta[/tex].  A confidence interval for the parameter θ, with confidence level [tex]\alpha[/tex] is the interval (a, b), where

P(a < [tex]\theta[/tex] < b) = [tex]\alpha[/tex], P is the probability

Here the  average commute time in minutes ([tex]\mu[/tex]) is to be calculated

95% confidence interval for the average commute time in minutes using public transit is (15.75, 28.25)

This means that it is 95% confident that the interval (15.75, 28.25) contains the population mean commute time in minutes using public transit

A population has a standard deviation of 10 and a mean of 75.

The sample mean has a standard deviation of 5 and an expectation of 100.The empirical rule states that there is a 68% probability of being between 95 and 105 (within one standard deviation of its expected value) if it is approximately normal.

What is meant by a standard deviation?

A measure of how dispersed the data are in relation to the mean is called the standard deviation (or ).Data with a low standard deviation are grouped around the mean, while data with a high standard deviation are more dispersed.

How can I determine the standard deviation?

Step 1: Locate the mean. Step 2: Find the square of the distance from the mean for each data point. Step 3: Sum the results of Step 2's values. Step 4: Divide by how many data points there are.
