The probability distribution with:

Narrowest /tallest : t-distribution with 25 degrees of freedom.

Widest/shortest :z distribution , t-distribution with both 106 and 1052 degrees of freedom

The possibility of something is how probable it is to happen. When we don't know how an event will turn out, we can talk about the probabilities of many outcomes—how likely they are. Statistics is the study of events with a probability component.

Tallest/narrowest: 25 degree of freedom t-distribution.

maximum/ minimum: z distribution, t-distribution with 106 and 1052 degrees of freedom.

The t-distribution and standard normal distribution are roughly equal and resemble each other in shape when the degrees of freedom reach 30 or more. As the degrees of freedom increase in the t-distribution, the area in the tails decreases as the area at the center decreases.

Given,

\( - 2.75p = - 19.25\)

\(p = \frac{19.25}{2.75} \)

\(p = 7\)

Answer:

A,D,E

Step-by-step explanation:

A:

14/4 = 3.5

D:

7/2 = 3.5

E: 14/4 = 3.5

The constant of proportionality for the table is 3.5. Any other table that satisfies the equations x/y = 3.5 will have the same constant of proportionality.

To find the constant of proportionality, we can divide the y-values by the corresponding x-values and see if they are the same for all given points. In this case, if we divide 24.5 by 7, we get approximately 3.5. If we divide 31.5 by 9, we also get approximately 3.5. Therefore, the constant of proportionality is 3.5 for this table.

Now, we need to find the relationships that have the same constant of proportionality.

For example, if we have a table with the following values:

x1 y1

x2 y2

x3 y3

and the constant of proportionality is k, then we have the following equations:

x1/ y1 = k

x2/ y2 = k

x3/ y3 = k

So, any other table that satisfies these equations will have the same constant of proportionality as the given table.

By expressing the odd numbers as 2a + 1 and 2b + 1, we can substitute them into the equation and simplify it to show that z is divisible by 2, proving that z will be even.

To prove that z will be even given x1 + x2 = z, where x1 and x2 are positive odd numbers:

1. Assume x1 = 2a + 1 and x2 = 2b + 1, where a and b are non-negative integers.

2. Substitute the values of x1 and x2 into the equation:

(2a + 1) + (2b + 1) = z.

3. Simplify the equation: 2(a + b + 1) = z.

4. Since a + b + 1 is an integer, let's denote it as c, where c = a + b + 1.

5. The equation becomes 2c = z, which implies z is divisible by 2.

6. By definition, an even number is divisible by 2. Thus, z is an even number.

Therefore, we have proven that if x1 and x2 are positive odd numbers, their sum z will always be an even number.

So, the volume of the can in cubic centimeters is 61.99 cm^3. If we round to the nearest tenth, the volume of the can is 62 cm^3.

A can of soda can be modeled as a right cylinder, which is a three-dimensional geometric shape with two circular bases that are connected by a curved surface. The volume of a cylinder can be calculated using the formula:

V = πr^2h

Where V is the volume, π is a constant (approximately equal to 3.14), r is the radius of the base and h is the height of the cylinder.

Given that the radius of the can is 2.6 cm and the height is 9.2 cm, we can substitute these values into the formula:

V = π (2.6 cm)^2 (9.2 cm)

To get the area of the base we need to square the radius and multiply by π, and then multiply it by the height to get the volume.

V = π * 6.76 * 9.2 = 61.99 cm^3

So the volume of the can in cubic centimeters is 61.99 cm^3. If we round to the nearest tenth, the volume of the can is 62 cm^3. This means that the can can hold 62 cubic centimeters of liquid.

It's worth noting that this is an approximation and the real value of π is not 3.14. Also, this answer is based on the assumption that the can is a perfect cylinder with no other gaps or spaces.

Answer:

Step-by-step explanation:

The perimeter of a triangle with sides l=m/3, n=l+m-15, and m is 65 feet. You want to know the lengths of the sides.

The perimeter is the sum of the side lengths.

  P = l +m +n

  P = (1/3)m +m +(l +m -15) = (1/3)m +m +(1/3)m +m -15

  65 = 8/3m -15 . . . . . simplify, use P=65

  80 = 8/3m . . . . . . . . add 15

  30 = m . . . . . . . . . . . multiply by 3/8

Then the other sides are ...

  l = 1/3m = 1/3(30) = 10

  n = l +m -15 = 10 +30 -15 = 25

The lengths of the sides are l = 10 ft, n = 25 ft, m = 30 ft.

Answer:

the answer is a y=1/2x-4

Answer:

\(\frac{3}{10} , 0.48 , 0.73\)

Step-by-step explanation:

In order to put this number in order from least to greatest, we have to turn them into fractions with the same denominator, so firstly we write down all of the decimals as fractions, and we will get...

\(0.48 = \frac{48}{100} \\\\0.73 = \frac{73}{100}\)

Now, we need to find the smallest number that is divisible by 100 and by 10, and this number will be the least common denominator. The smallest number that is divisible by 100 and by 10 is 100, therefore 100 is the least common denominator. Now we have to make all of the fractions have the denominator of 100 and we do that in the following way...

\(\frac{48}{100}= \frac{48}{100}\\\\\frac{73}{100} = \frac{73}{100}\\\\\frac{3}{10} = \frac{(3)(10)}{(10)(10)} = \frac{30}{100}\)

By looking at this we need to understand that...

\(\frac{30}{100}<\frac{48}{100}<\frac{73}{100}\)

Therefore...

\(\frac{3}{10} < 0.48 < 0.73\)

The truck is on pace.

Step-by-step explanation:

To find which truck will arrive first, you need to find each vehicle's mph. To get the mph of each vehicle you just need to divide the distance by time.

Bus: 110 (miles) ÷ 2 (hours) = 55 (miles per hour)

Truck: 180 (miles) ÷ 3 (hours) = 60 (miles per hour)

When you do this you can see the mph of the bus is < the mph of the truck.

Answer:

A. 5y = 45.00; y = 9.00

Step-by-step explanation:

Step 1:

There are 5 friends in total and since we don't know how much money each of them contributed to the total amount ($45.00), we will substitute it with the variable y.

So, the amount of money the friends contributed is 5y.

The total amount of all the friends' money put together is given; $45.00.

So 5y = 45.00

______________

Step 2:

Divide 45.00 by 5 to find out how much each of the five friends contributed individually;

45.00 ÷ 5 = 9.00

So the amount of money the each friend contributes individually/ have to spend to buy a present for her individually is $9.00.

y = 9.00

Combining like terms is commonly used to solve algebraic expressions. Like terms are those species or variables that are the same in any algebraic representation.

  Different mathematical operations can be performed on like species. We can add, divide, multiply, subtract, factorize, etc those terms.

Take for example;

COS <AB = OA/OB = 4/10 = 2/5 =

COS< COB = OC/OB = 4/10 = 2/5

=> <AOC = <AOB + <COB

=> <AOC = Cos-¹(2/5) + Cos-¹(2/5)

=> <AOC = 2 Cos-¹(2/5)

=> <AOC = 2 * 66.42

=> <AOC = 132.84°

if D is in minor arc then length of arc ADC. = ( 132.84°/360°) 2π = 9.274 cm
