Answer:

The probability that they are the three youngest students is 0.002197.

Step-by-step explanation:

If 3 students are randomly selected from 15 available students, the probability that they are the three youngest students = 1 / 15C3

15C3=\frac{15!}{3!12!}

= 455

= \frac{1}{455}

= 0.002197

The input of a function (w) is height (in centimeters). The output is weight (in pounds). What does W (183) = 212 mean?
inysia [295]

This equation means that you mustfind the height which in this case is W. ok in order to find w you must do the opposite equation to the output so divide 183 by 212 and the answer is W so W=.9 ( im only in 9th grade so this may or may not be correct)

Ahat [919]

Answer:

3,000 miles

Step-by-step explanation:

Calculation for the distance, in miles, between Mora's house and her cousin's house

Distance in miles =(2centimeters÷20centimeters) *300 miles

Distance in miles=10*300 miles

Distance in miles= 3,000 miles

Therefore the distance, in miles, between Mora's house and her cousin's house will be 3,000 miles

What is 8 21/40 I don't understand how to do it
yaroslaw [1]
Hey, there !

If you want to know it as a "improper fraction" , you can

Multiply the denominator from the front number
Whatever the denominator and front number is , you add it to the numerator

So, for this problem we first have the multiply the front number from the denominator

Like: 8 (40)
That gives us the answer of: 320

Now we have to add 320 to 21

Like: 320 + 21

That gives us the answer of:341

We keep our denominator (which is "40" )

Your improper fraction would be:

341 / 40

Good luck on your assignment and enjoy your day!

Can anybody help me pleasee I don't understandd
o-na [289]
Hello there.

6(8 - 2y) = 4y

To solve for this, we need to apply the Distributive Property to the left side of the equation. This property allows us to multiply the number outside of the parenthesis by all numbers inside of the parenthesis.

6(8 - 2y)
6(8) + 6(-2y)
48 - 12y

Now, let’s take a look at our equation.

-12y + 48 = 4y

To make things more simple, we’ll add 12y to both sides of the equation. This will cancel out -12y on the left side of the equation and will turn 4y on the right side of the equation into 16y.

Our new equation is:

16y = 48

Now all we need to do is divide both sides by 16 to solve for y.

16y / 16 = y
48 / 16 = 3

Our final answer and solution is:

Y = 3

I hope this helps!

Simplify the following expression. (2x-3)(5x^4-7x^3+6c^2-9)
jasenka [17]

The simplification of the expression (2x - 3)(5x⁴ - 7x³ + 6x² - 9) is 10x^5 - 29x⁴ + 33x³ - 18x² - 18x + 27

<h3>Simplification</h3>

(2x - 3)(5x⁴ - 7x³ + 6x² - 9)

= 10x^5 - 14x⁴ + 12x³ - 18x - 15x⁴ + 21x³ - 18x² + 27

= 10x^5 - 14x⁴ - 15x⁴ + 12x³ + 21x³ - 18x² - 18x + 27

= 10x^5 - 29x⁴ + 33x³ - 18x² - 18x + 27

The simplified expression is 10x^5 - 29x⁴ + 33x³ - 18x² - 18x + 27
