So, the probability that you see at least one shooting star in the period of an hour is 59.04%.

The probability of seeing at least one shooting star in a 15-minute interval is 20%, so the probability of not seeing a shooting star in that interval is 80%. The probability of not seeing a shooting star in an hour-long period is the product of the probability of not seeing a shooting star in each of the four 15-minute intervals, which is 0.8 * 0.8 * 0.8 * 0.8 = 0.4096 or 40.96%. Therefore, the probability of seeing at least one shooting star in an hour-long period is 1 - 0.4096 = 59.04%.

To find the first employee who commutes by bus, you would need to sample at least 5 employees (since 20% of employees commute by bus, and 1/5 is equal to 20%).

However, if you wanted to increase the likelihood of finding the first employee who commutes by bus, you may need to sample more employees. To find the first employee who commutes by bus, you can use the concept of probability.

Since 20% of the business's employees commute by bus, there's a 1 in 5 chance that a randomly selected employee will be a bus commuter. On average, you would need to sample 5 employees in order to find the first employee who commutes by bus.

Question:

Sue is thinking of a number 3/8 of 88 = 1/3 of her number

what number is she thinking of

Answer:

\(x = 99\)

Step-by-step explanation:

Represent the number with x.

So, we have:

\(\frac{3}{8} * 88 = \frac{1}{3} *x\)

Multiply through by 3

\(3 * \frac{3}{8} * 88 = \frac{1}{3} *x * 3\)

\(3 * \frac{3}{8} * 88 = x\)

\(3 * 3 * 11 = x\)

\(99= x\)

\(x = 99\)

Hence, she is thinking of 99

The probability that the gambler will win her bet is approximately 0.00476, or 0.476%.

To calculate the probability of the gambler winning her bet, we need to determine the total number of possible outcomes and the number of favorable outcomes.

In this case, there are seven horses, and the gambler must pick the top three finishers in the correct order. The total number of possible outcomes can be calculated using the concept of permutations.

The first-place finisher can be any one of the seven horses. Once the first horse is chosen, the second-place finisher can be any one of the remaining six horses. Finally, the third-place finisher can be any one of the remaining five horses.

Therefore, the total number of possible outcomes is: 7 * 6 * 5 = 210

Now, let's consider the favorable outcomes. The gambler must correctly pick the top three finishers in the correct order. There is only one correct order for the top three finishers.

Therefore, the number of favorable outcomes is: 1

The probability of the gambler winning her bet is given by the number of favorable outcomes divided by the total number of possible outcomes:

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = 1 / 210

Simplifying the fraction, the probability is:

Probability = 1/210 ≈ 0.00476

Therefore, the probability that the gambler will win her bet is approximately 0.00476, or 0.476%.

Answer: 24

Step-by-step explanation: first we can rewrite the expression as 170%*x=40.8 (x is your answer). By solving and simplifying it, you should get 24.

The first terms are a_1=  -4  a_2= -8/3  a_3= -16/9  a_4= -32/27

The series converges as a result  the series' sum, if it exists, is equal to -12.

What exactly are geometric series?

A geometric sequence is a set of numbers where each phrase following the first is obtained by multiplying the previous term by the common ratio , a constant. Consider the order 2, 4, 8, 16, 32, etc. as an example. Given that each term after the first is derived by multiplying the previous term by 2, this geometric series has a common ratio of 2.

The following is the formula for determining the nth term in a geometric sequence:

a n = arⁿ⁻¹

where "a" denotes the initial word and "r" denotes the common ratio 2.

A geometric sequence of infinite nature is the sum of an infinite geometric series. ¹. The following formula is used to calculate the sum of an infinite geometric series:

sum = a/ (1-r)

where "r" is the common ratio and "a" is the first term.

n=1, 2, 3, and 4 can be added to the formula for the nth term of a geometric sequence to find the first four terms of the series:

a n = arⁿ⁻¹

where r is the common ratio and an is the first term. As a result, we have:

n= 1

= -4(2/3)⁽¹⁻¹⁾   =  -4

n= 2

= -4(2/3)⁽²⁻¹⁾   = -8/3

n=3

= -4(2/3)⁽³⁻¹⁾  =   -16/9

n=4

= -4(2/3)⁽⁴⁻¹⁾  = -32/27

b) b) We must locate the common ratio "r" in order to establish whether the series converges or diverges. In this instance, r=2/3, satisfying |r|<1 ⁵ The series converges as a result.

c) The formula for the sum of an infinite geometric series can be used to determine whether the series has a sum.

sum = a/ (1-r) (1-r)

where "r" is the common ratio and "a" is the first term. In this formula, substituting a=-4 and r=2/3 results in:

sum = -4 / (1-2/3)

= -12

Answer:

y = 65 when x = 13

Step-by-step explanation:

Here we have a proportion problem.

Y varies directly as x means that y equals the product of x and a constant

Let’s say our constant is k

Thus;

y = kx

now, k = y/x

Using the initial values;

k = 25/5 = 5

Now we want to get y when x = 13

Recall; y = kx

Thus using the value of k earlier calculated;

y = 13 * 5

y = 65

6 miles away

-Chetan K

The actual distance between the two trails is 6 miles.

Given the scale of the map is 2 inches to 1.5 miles, we can set up a proportion to find the actual distance between the two trails.

Let x represent the actual distance between the trails in miles. The proportion would be:

(2 inches / 1.5 miles) = (8 inches / x miles)

Now, solving for x:

2/1.5 = 8/x

Cross-multiplying:

2x = 1.5 × 8

2x = 12

Divide by 2:

x = 6

So, the actual distance between the two trails is 6 miles.

The smallest positive solution to the equation sin(6x) cos(10x) - cos(6x) sin(10x) = 0.8 is x ≈ 0.53.

To solve the equation, we can use the trigonometric identity for the difference of angles: sin(A - B) = sin(A) cos(B) - cos(A) sin(B). Comparing it with the given equation, we can see that A = 6x and B = 10x.

Applying the identity, we have sin(6x - 10x) = 0.8. Simplifying further, we get sin(-4x) = 0.8.

To find the value of x, we need to find the angle whose sine is 0.8. Using inverse sine (arcsin) or a calculator, we find that the angle whose sine is 0.8 is approximately 53.13 degrees or 0.9273 radians.

Since we want the smallest positive solution, we take x ≈ 0.9273/4 ≈ 0.232. However, we need to express the answer accurately to two decimal places, so the final solution is x ≈ 0.23 (rounded to two decimal places).

Answer:

A) 15

B) 20

C) 40

Step-by-step explanation:

If you complete each square then divide your answer for the new completed side by 2 then add it to the whole then you should get your answer.

For example square one. Make a new line going down the right side the same as the left and now you have 1 square and 2 triangles.

Then close off each side triangle to make it a square which would look like a triangle was sandwiched on top of it to make it a square.

Now your base of 7 on the bottom is actually 2+3+2=7 because the segment on top breaks up the 7 into 3 in the middle and 2 on each other side.

So essentially you now have a 2 by 3 next to a 3 by 3 next to a 2 by 3 again.

Solve for the sides and divide those by two to get your area for those 2 sides.

which gives us 3 because 2x3=6 6/2=3

For each side added you get 3+3=6 So now all you need is the middle square which is 3x3=9

This gives us 6+9=15

This is how you would do the other 2 squares. Finish the triangle to make it a square to get the area for that. Then divide by 2.

The expected value is $ 110

One of two possible outcomes will follow a decision. one outcome yields a $75 payoff and has a probability of 0.3;

the other outcome has a $125 payoff and has a probability of 0.7.

expected value = probability of a outcome x the outcome

= 75 (0.3) + 125(0.7)

= 22.5 + 87.5

= 110

the expected value is $ 110

Therefore, if one outcome yields a $75 payoff and has a probability of 0.3; the other outcome has a $125 payoff and has a probability of 0.7. in this case the expected value is $ 110

The graph of y=6(0.5)x is a decreasing exponential function.

Graph is a data structure that consists of nodes and edges. Nodes are the points which are connected by edges. Graphs are used to represent relationships between different objects, and can be used to represent real-world scenarios such as social networks, road networks, and other types of networks. Graphs are widely used in data science, machine learning, AI, and many other fields. Graphs are powerful because they can show complex relationships between data points that would otherwise be difficult to understand. With graphs, it is easier to analyze and visualize data, allowing for better decision-making.

This is because the exponent, 0.5, is a fraction less than 1, meaning that the value of y decreases at a faster rate with increasing x. This is why the graph is not a straight line, because the slope decreases with increasing x. Furthermore, the y-intercept is (0,6), meaning that the graph starts at 6 on the y-axis and decreases from there. Additionally, the x-intercept is (0.5,0), meaning that the graph crosses the x-axis at 0.5 and decreases from there. Finally, the equation of the asymptote is x=0, indicating that the graph approaches x=0 asymptotically as x approaches infinity. Thus, the graph of y=6(0.5)x is a decreasing exponential function.

Therefore, the transition matrix from b to b' is:

[ -2 -3 4 2 ]

[ 3 3 -4 -2 ]

[ -1 -1 2 1 ]

[ -2 -2 5 3 ]

To find the transition matrix from basis b to b', we need to express each vector in b' as a linear combination of the vectors in b, and put the coefficients as columns in the matrix.

We have:

(-2, 3, -1, -2) = a1(1, 0, 0, 0) + a2(0, 1, 0, 0) + a3(0, 0, 1, 0) + a4(0, 0, 0, 1)

= a1(1, 0, 0, 0) + a2(0, 1, 0, 0) + a3(0, 0, 1, 0) + a4(0, 0, 0, 1)

Solving this system, we get a1 = -2, a2 = 3, a3 = -1, and a4 = -2.

Similarly, we can express the other three vectors in b' as linear combinations of the vectors in b:

(-3, 3, -1, -2) = -3(1, 0, 0, 0) + 3(0, 1, 0, 0) - (1, 0, 0, 0) - 2(0, 0, 0, 1)

(2, -2, 1, 2) = 4(1, 0, 0, 0) - 4(0, 1, 0, 0) + 2(0, 0, 1, 0) + 5(0, 0, 0, 1)

(4, -4, 2, 5) = 2(1, 0, 0, 0) - 2(0, 1, 0, 0) + 1(0, 0, 1, 0) + 3(0, 0, 0, 1)

The residual for this observation is 31.05.

As per given data in question ,

Starting price of a used game with one wheel = 0.99

Total observed price = 37.04

We have to calculate the residual, we need to first calculate the predicted value using the linear regression equation, then subtract the predicted value from the observed value.

Linear regression equation: `

y = mx + b`

Here, `y` is the dependent variable, which is the total price of the sale. `x` is the independent variable, which is the starting price of the used game. `m` is the slope of the regression line, which can be calculated as:

`m = (y2 - y1) / (x2 - x1)

`Where `(x1, y1)` and `(x2, y2)` are any two points on the line.

Let's use the following two points:

`(0.99, 5.99)` and `(40.00, 44.00)`.

Therefore, `m = (44.00 - 5.99) / (40.00 - 0.99) = 0.9303`

Now, to find `b`, we need to substitute the slope and one of the points in the equation `y = mx + b`.

Let's use the point `(0.99, 5.99)`.

Therefore, `5.99 = 0.9303(0.99) + b`,

which gives `b = 5.10`.

Thus, the linear regression equation is `y = 0.9303x + 5.10`.

Now, to calculate the predicted value, we need to substitute the starting price in the equation.

Here, the starting price is 0.99. Therefore, `y = 0.9303(0.99) + 5.10 = 5.99`.

Hence, the predicted value is $5.99.

To calculate the residual, we need to subtract the predicted value from the observed value.

Therefore,

`residual = observed value - predicted value = 37.04 - 5.99 = 31.05`.
