In 25 ways we can select 2-digit number from the given digits.

Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set. The symbol nPr is used to denote the number of permutations of n distinct objects, taken r at a time.

Given that, a two-digit number whose 1st digit it 0,1,2,3, or 4, and whose 2nd digit is 5,6,7,8, or 9.

Number of ways selecting 1st digit is

P(5, 1) = 5!/(5-1)!

= 5

Number of ways selecting 2nd digit is

P(5, 1) = 5!/(5-1)!

= 5

Now, 5×5=25

Therefore, in 25 ways we can select 2-digit number.

The percentage K 25 that is 25 t, can be found to be 1 % .

The relationship between K and t is such that 1 K has 100 t.

This means that K 25 in terms of t, would be:

= 25 x 100

= 2, 500 t

The percentage of K that is 25 t is therefore :

= 25 / 2, 500

= 1 / 100

= 0. 01

= 1 %

In conclusion, when given the values K 25 and 25 t, then 25 t would be  1 % of K 25.

The boat that will cost Stephanie less to buy and use is boat B, and the difference between the cost is $11.7.

Let's calculate first the cost of each boat:

Boat A

cost + repairs + gasoline for 3 years= total cost

2400 + 600 + gasoline cost

gasoline cost = 40 / 15 = 2.66 gallons per month x 36 = 95.76 X 3.89 = 372.5

2400 + 600 + 372.5 = 3,372.5

Boat B

cost + repairs + gasoline for 3 years= total cost

2800 + 250 + gasoline cost

gasoline cost = 40 / 18 = 2.22 gallons per month x 36 = 79.92 X 3.89 = 310.88

2800 + 250 + 310.88 = 3,360.88

Using the unitary method, we find that the store created approximately 37 bags with 15 random cards in each bag.

This problem can be solved using the unitary method. It is given that the

number of Anniversary cards is 163,

number of Birthday cards is 258,

number of Get Well cards is 98

and the number of Thank you cards is 47

So, the total number of cards will be equal to the sum of all these cards, that is,

163+258+98+47

= 566 cards

To create bags of 15 random cards, we have to divide the total number of cards by 15  which gives,

566/15 = 37.734

Thereby, we can say that the store created approximately 37 bags with 15 random cards in each bag.

The conversion factor should have gallons in the denominator and the equation will be 350 gallons = 92.3 L

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the amount of gallons of water be = 350 gallons

And , 1 gallon = 3.79 liters

So , the amount of 350 gallons = ( 350 ) x ( 1/3.79 ) L

Substituting the values in the equation , we get

The amount of 350 gallons = ( 350 / 3.79 ) L

On simplifying the equation , we get

The amount of 350 gallons = 92.3 L

Answer:

Step-by-step explanation:

The correct answer is C. Shading will be above the y=-2x+1 line but below the y= 3x-1 line.

The line y=-2x+1 is a line with a slope of -2 and a y-intercept of 1. It represents the solutions that are greater than -2x+1.

The line y=3x-1 is a line with a slope of 3 and a y-intercept of -1. It represents the solutions that are less than 3x-1.

So, when you graph both of these lines on the same coordinate plane, the solutions that satisfy both inequalities will be the region that is above the line y=-2x+1 but below the line y=3x-1, and this is the region that will be shaded.

The choice between using the standard deviation and standard error in the denominator of a z-score formula depends on the context of the problem and the type of data being analyzed.

To determine which z-score formula to use, consider the type of data and the context of the problem. If you have a sample with a known population standard deviation, use the first formula.  If the data represents a random sample of a larger population, the standard error is typically used to account for the variability in estimating the population mean. On the other hand, if the data represents the entire population, the standard deviation is used as the denominator. It's important to understand the distinction between a sample and a population and to choose the appropriate formula accordingly.

As we can see from graph for given linear inequality -0.25≥-0.5x, the graph will be a number line with a closed circle on 0.5 with an arrow shaded right.

What exactly are linear inequalities?

Inequality is a mathematical statement in which neither side is equal. In Math, an inequality occurs when a connection produces a non-equal comparison between two expressions or two integers. The equal sign "=" in the phrase is substituted by any of the inequality symbols, such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤), or not equal to symbol (≠). In mathematics, there are three types of inequalities: polynomial inequalities, rational inequalities, and absolute value inequalities.

The symbols "< and '>' represent severe inequalities, whereas  ‘≤’ and ‘≥’  represent slack inequalities. A linear inequality appears to be the same as a linear equation, however there is a difference.

Now,

Given linear inequality is -0.25≥-0.5x

0.25≤0.5x

1/4≤1/2x

x≥1/2

hence,

I now have a better understanding of how pollsters use this measure to determine the reliability of their results.

Additionally, the article highlighted the importance of understanding statistical significance, which refers to the likelihood that a particular result occurred by chance. This is an essential concept in statistics that helps to determine whether a particular result is reliable or not.
