The required probability for the 2 men's names are selected is 0.358.

Given that,
A doctor has 2 doses of flu protection vaccine left. He has 5 women and 8 men who want the medication.
The names of 2 of these people are selected at random, determining the probability that 2 men's names are selected is to be determined,

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,
The number of ways to select 2 men = 8C2 = 28
The number of ways to select 2 people from 13 = 13C2 = 78
The probability of the 2 men's names being selected = 28 / 78 = 0.358

Thus, the required probability for the 2 men's names are selected is 0.358.

the only criteria, really, to be a function is to assign exactly 1 y-value to every valid x-value. not 2 or 0 y-values.

we see here, x = 2 has one assigned y-value : y = 3.

x = 4 has y = 9.

x = 6 has y = 10.

x = 9 has y = 5.

there is no indication that there are more valid x-values.

each x-value used has exactly 1 y-value.

so, the criteria is fulfilled. it is a function.

The sales Jamie made for the week is $530

information from the problem

Jamie is a salesperson in a jewelry store and earns $150 per week, plus 15% of her weekly sales

Jamie makes $229.50 in one week, her sales for that week = ?

The question is a percentage problem, percentage deals with a fraction hundred and used as follows

15% = 15 percent

= 15 / 100

= 0.15

Let Jamie's sales for the week be x

total earning = 150 + 0.15x

229.50 = 150 + 0.15x

229.50 - 150 = 0.15x

0.15x = 79.5

x = 79.5 / 0.15

x = 530

Yaritza made 25% of her free throws over the season. If she shot 160 free throws, 40 many did she make. Using the concept of percentage.

When a fraction of a whole is represented as a number between 0 and 100, it is called a percentage. All of something is 100 percent, half of it is 50 percent, and none of it is 0%. To calculate a percentage, multiply the result by 100 after dividing the part of the whole by the entire.

When the denominator is 100, percentages are really just fractions. The percent sign (%) is placed next to a number to indicate that it is a percentage. For instance, you would have received a 75% on the examination if you correctly answered 75 out of 100 questions (75/100).

An easy way to solve this problem is by first finding 50%.

To find 50% of 160

= 160 × (50/100)

= 80

So, 160.0 becomes 80.

Then, because 25% is half of 50% to find the answer divide 80 by 2.

Therefore, Yaritza made 40 of her 160 free throws.

on the number line, 2.0 is to the right of 2, and multiplying 2.0 by 10 moves it 10 times as far to the right as 2.0 is from 2. This is why 2 is 10 times the value of 2.0.

What is the number line?

The number line is a visual representation of the set of all real numbers, which are the numbers that can represent any value on the continuous number scale, including fractions and decimals. On the number line, each point corresponds to a specific real number.

The number 2 is represented by a point on the number line, as is the number 2.0. These two numbers are different because 2.0 is a decimal number, while 2 is a whole number.

2 is 10 times the value of 2.0 if you multiply 2.0 by 10. This is because multiplying a number by 10 shifts its decimal point one place to the left, which increases its value by a factor of 10. For example, if you multiply 2.0 by 10, you get 20.0, which is 10 times the value of 2.0.

Hence, on the number line, 2.0 is to the right of 2, and multiplying 2.0 by 10 moves it 10 times as far to the right as 2.0 is from 2. This is why 2 is 10 times the value of 2.0.

Reason:

The leading coefficient is 6, which is the coefficient of the leading term (aka the first term). The constant is 5, which is the last term.

Here are some examples of what f(x) could be.

[tex]f(\text{x}) = 6\text{x}^2+\text{x}+5\\\\f(\text{x}) = 6\text{x}^3+2\text{x}^2-7\text{x}+5\\\\f(\text{x}) = 6\text{x}^5+4\text{x}^3-81\text{x}^2+5[/tex]

The middle terms don't matter and neither does the exponent on the leading term.

So this is what the general template would look like

[tex]f(\text{x}) = 6\text{x}^{n}+\ldots+5\\\\[/tex]

where n is a positive integer.

If we were to plug in x = 0, then all of the terms involving x go to zero. They cancel out. The only thing left standing would be the "5" at the very end.

So,

[tex]f(\text{x}) = 6\text{x}^{n}+\ldots+5\\\\f(0) = 6*0^{n}+\ldots+5\\\\f(0) = 0+0+\ldots+0+0+5\\\\f(0) = 5\\\\[/tex]

In short, the constant value is the y intercept of the polynomial curve. It allows us to quickly spot it without having to do much (or any) math.

This is why choice B is a false statement.

The other answer choices cannot be proven true or false since we don't have enough information about this particular function.

What do you mean by algebraic expression?

The concept of algebraic expressions is the use of letters or alphabets to represent numbers without providing their precise values. We learned how to express an unknown value using letters like x, y, and z in the fundamentals of algebra. Here, we refer to these letters as variables. Variables and constants can both be used in an algebraic expression. A coefficient is any value that is added before a variable and then multiplied by it.

Given expression:

4n - 5r

When n = -2 and r = 3

The value of the expression become,

4(-2) - 5(3)

= -8 - 15

= -23

Hence, option D is correct.

Now, it is given that the surface area for a rectangular prism with a square base is given by the expression 2s²+4sh, where s is the side length of the square h is the height of the prism.

The surface area in square feet rectangular prism when s=4 feet and h=6feet is

To determine the total cost of the DVD, you need to calculate the amount of sales tax and add it to the cost of the DVD.

The sales tax is equal to the cost of the DVD multiplied by the sales tax rate:

Sales tax = $18.99 * 6.5% = $1.23

To determine the total cost, you need to add the cost of the DVD to the sales tax:

Total cost = $18.99 + $1.23 = $20.22

So the total cost of the DVD is $20.22.

The amount the three-dimensional space that's also occupied is measured in volume. To define it quantitatively, a variety of imperial either Us or metric system, in addition to SI-derived units such as the cubic meter but instead liter), are widely utilized. A symbiotic relationship exists between volume and length (cubed).

Mathematics refers to volume as the measurement of internal space in a specific 3D object. A fish tank, for instance, is three feet long, one foot broad, and two feet high. Expanding the length, that width, and the height results in the volume, which is equal to six when 3x1x2 is used. Consequently, the fish tank can hold 6 cubic feet of water.

What is Inverse of a Function ?

A function takes in values, applies specific operations to them, and produces an output. The inverse function acts, agrees with the outcome, and returns to the initial function.

The output of a function is returned by the inverse function, which also returns the initial value.

If f and g are inverse functions, then f(g(x)) = g(f(x)) = x. The initial value is fetched via a function that is its inverse.

For instance, f(x) = 2x + 5 = y

Therefore, the inverse of f is g(y) = (y-5)/2 = x. (x).
