duane spins a fair spinner what is the probability it will land on 4 write your answer as a decimal

In statistics, the t-distribution is a probability distribution that is used to make inferences about the population mean when the sample size is small and/or when the population standard deviation is unknown.

To determine the t-critical value that will capture the desired t-curve area, we need to consider the degrees of freedom (df) and the type of area (central, upper-tail, or lower-tail) we are interested in.

It is important to note that as the degrees of freedom increase, the t-critical values approach the corresponding z-values from the standard normal distribution. This means that for large sample sizes, we can use the standard normal distribution instead of the t-distribution.

Step-by-step explanation:

It appears that I know the answer to this question.

Taner will only need to run 3 km this week to complete his 6 km running goal.

If we require a definition, we may start by saying that fractional numbers are numbers that symbolize one or possibly more portions of a unit that has been subdivided into equal parts.

Given that, Taner's overall running goal is 6 km (including last week and this week)

So,

Taner's 2-week goal is 6 kilometres.

Now,

Taner's goal for the week is 3 kilometres = (6/2).

As the Taner completed 3 km of running last week. Taner can achieve his objective this week by running just 3 miles.

Answer:

w = 10

Step-by-step explanation:

First we take the two values for the breadth of the rectangle

So:

5x - 9 = 3x + 7

now we solve this equation as follows:

5x - 3x = 9 + 7

2x = 16

x = 8

now that we have found the value for x, we can substitute it in the equation, 5x - 9,or in the equation, 3x + 7.

when we substitute x in any of these equations, we get

5(8) - 9 = 31

3(8) + 7 = 31

now that we have the value for the breadth we can form the following equation:

31 × w = 310

31w = 310

w = 310/31 = 10

Answer:

10

Step-by-step explanation:

Firstly, we find the value of X

since 5X-9 and 3X+7 are lenghts

5X-9= 3X+7

5X-3X= 7+9

2X = 16

dividing bothsides by 2

2X/2= 16/2

X = 8

Hence,

5X-9= 5(8)-9= 40-9 = 31

3X+7=3(8)+7= 24+7= 31

To find the width

Area= lenght×width

310= 31×w

31w= 310

w= 310/31

W= 10

Answer:

I believe number 9 is the middle answer

Step-by-step explanation:

please correct me if I'm wrong

(a) a = 9, 3, b = -2, 6 are orthogonal

(b) a = 4, 7, -2, b = 3, -1, 7 are neither parallel nor orthogonal

(c) a = -6i + 9j + 3k, b = 4i - 6j - 2k are neither parallel nor orthogonal

(d) a = 3i - j + 3k, b = 3i + 3j - 2k are orthogonal

(a) To determine if vectors a = (9, 3) and b = (-2, 6) are orthogonal, parallel, or neither, first check if their dot product is 0. If it is, they are orthogonal.

a · b = (9 * -2) + (3 * 6) = -18 + 18 = 0, so a and b are orthogonal.

(b) For vectors a = (4, 7, -2) and b = (3, -1, 7), calculate the dot product.

a · b = (4 * 3) + (7 * -1) + (-2 * 7) = 12 - 7 - 14 = -9, which is not 0, so they are not orthogonal. Since the vectors are not scalar multiples of each other, they are neither parallel nor orthogonal.

(c) For vectors a = (-6i + 9j + 3k) and b = (4i - 6j - 2k), check the dot product:

a · b = (-6 * 4) + (9 * -6) + (3 * -2) = -24 - 54 - 6 = -84, which is not 0, so they are not orthogonal. Since the vectors are not scalar multiples of each other, they are neither parallel nor orthogonal.

(d) For vectors a = (3i - j + 3k) and b = (3i + 3j - 2k), calculate the dot product:

a · b = (3 * 3) + (-1 * 3) + (3 * -2) = 9 - 3 - 6 = 0, so a and b are orthogonal.

Answer:

15 Dollars

Step-by-step explanation:

If you take the shipping price (3 dollars) off you get 15 per shirt

If Greg paid $33 for 2 shirts and $48 for 3 shirts including a fixed shipping fee then one shirt costs $15 before the shipping fee.

Two or more expressions with an Equal sign is called as Equation.

Given that Greg paid $33 for 2 shirts and $48 for 3 shirts including a fixed shipping fee.

We have to find the cost of one shirt before the shipping fee.

Let x be the cost of one shirt before the shipping fee.

Then, we can set up two equations based on the given information:

2x + shipping fee = 33

3x + shipping fee = 48

We can solve for the shipping fee by subtracting the first equation from the second:

3x + shipping fee - (2x + shipping fee) =48 - 33

x= 48 - 33

x = 15

So one shirt costs $15 before the shipping fee.

Hence,  if Greg paid $33 for 2 shirts and $48 for 3 shirts including a fixed shipping fee then one shirt costs $15 before the shipping fee.

It's important to note that this calculation assumes that the items in each category are distinct and that Soo Jin can select any item from each category without any restrictions or dependencies.

To determine the number of different possible characters Soo Jin can create for the video game, we need to consider the combinations of items from each category.

Let's assume there are n1 items in Category 1, n2 items in Category 2, n3 items in Category 3, and n4 items in Category 4. To find the total number of possible characters, we multiply the number of options in each category:

Total number of characters = n1 * n2 * n3 * n4

For example, if Category 1 has 5 items, Category 2 has 3 items, Category 3 has 2 items, and Category 4 has 4 items, the total number of possible characters would be:

Total number of characters = 5 * 3 * 2 * 4 = 120

So Soo Jin can create 120 different characters by selecting one item from each of the four categories.

Answer:

x = 85

y = 65

Step-by-step explanation:

By interior angle sum property of a triangle.

y° + 25° + 90° = 180°

y° + 115° = 180°

y° = 180° - 115°

y° = 65°

y = 65

By remote interior angle theorem of a triangle:

x° = y° + 20°

x° = 65° + 20° (since y = 65)

x° = 85°

x = 85

Excessive punishment or negative reinforcement can harm a child's math achievement by creating fear, undermining confidence, and discouraging engagement with the subject. Positive discipline techniques and a supportive environment are crucial for fostering math success.

Excessive punishment or negative reinforcement as a discipline technique can have detrimental effects on a child's math achievement. When a child makes mistakes or struggles with math concepts, responding with punishment, criticism, or harsh consequences can create a negative association with math. This can lead to anxiety, fear, and a lack of motivation to engage with the subject.

Mathematics requires a growth mindset, where mistakes are seen as opportunities for learning and improvement. By punishing or negatively reinforcing a child's math mistakes, we discourage them from taking risks, trying new strategies, and seeking help when needed. It hampers their ability to develop problem-solving skills and critical thinking abilities.

Furthermore, negative discipline approaches can damage a child's self-esteem and confidence in their mathematical abilities. They may develop a belief that they are "bad at math" or incapable of improving, leading to a self-fulfilling prophecy where their performance suffers.

To support a child's math achievement, it is essential to employ positive discipline techniques. This includes providing constructive feedback, offering assistance and guidance, creating a safe and supportive learning environment, and promoting a growth mindset. Encouraging effort, perseverance, and celebrating small successes can foster a positive attitude towards math and enhance a child's mathematical abilities.

Answer:

\(\mathbf{ f(x+1)=7x-1}\)

Step-by-step explanation:

We need to find f(x+1)

We are given:

\(g(x) - f(x) = -2x + 5\:and\:g(x) = 5x -3\)

First we need to find f(x)

By putting value of g(x) into g(x)-f(x)

\(g(x) - f(x) = -2x + 5\\\Put\:value\:of\:g(x) = 5x -3\\5x-3-f(x)=-2x+5\\-f(x)=-2x+5-5x+3\\-f(x)=-2x-5x+5+3\\-f(x)=-7x+8\\f(x)=-(-7x+8)\\f(x)=7x-8\\\)

We have, \(f(x)=7x-8\)

Now finding f(x+1) by putting x=x+1

\(f(x)=7x-8\\Put\:x=x+1\\f(x+1)=7(x+1)-8\\f(x+1)=7x+7-8\\f(x+1)=7x-1\)

So, \(\mathbf{ f(x+1)=7x-1}\)

The domain is the x value and the range is the y value.

Because x is a variable it can be any real number so the domain would be negative infinity to infinity.

Because the domain is negative infinity to infinity, then the range is also negative infinity to infinity.

The triangle C is reduced by a scale factor of 0.36 to form triangle D.

Given,

There are two triangles are C and D.

All sides of C are 35 in, 25 in, 45 in and all sides of D are 7 in, 9 in,5 in.

To find the scale factor by which triangle C is dilated or reduced to form triangle D, we need to compare the corresponding sides of both triangles.

The corresponding sides of triangle C and D are:

35 in : 7 in (longest sides of each triangle)

25 in : 9 in

45 in : 5 in

To find the scale factor, we can choose any pair of corresponding sides and divide the length of the side in triangle D by the length of the corresponding side in triangle C.

Let's choose the second pair of corresponding sides, which are 25 in and 9 in.

scale factor = length of corresponding side in triangle D / length of corresponding side in triangle C

scale factor = \( \frac{9 \: in}{25 \: in} \)

scale factor = 0.36

Therefore, triangle C is reduced by a scale factor of 0.36 to form triangle D.
