If Professor Wilson found that the test scores of his students had a variance of 4.4, what is the standard deviation? Type a numerical answer in the space provided. Round your answer to the nearest tenth.
Answers
Answer:
The standard deviation will be: 2.1
Step-by-step explanation:
We know that standard deviation is basically the square root of variance.
Using the formula to calculate the standard deviation
[tex]s=\sqrt{s^2}[/tex]
As
The variance = s² = 4.4so the standard deviation can be calculated as:
standard deviation [tex]=\sqrt{s^2}[/tex]
[tex]=\sqrt{\left(4.4\right)^}[/tex]
[tex]=2.1[/tex]
Therefore, the standard deviation will be: 2.1

Lorena compró en una tienda una remera, un pantalón y una cartera. Se sabe que el pantalón cuesta $400 más que la remera, y la cartera cuesta 5 veces el valor de la remera. Si por los tres objetos pagó, en total, $2850, ¿cuál es precio de cada uno?
Answers
Responder:
Costo de la camisa = $ 350
Pantalón = $ 750
Billetera = $ 1750
Explicación paso a paso:
Artículos comprados :
Camiseta (t); pantalones (p); y billetera (w)
El pantalón cuesta 400 más que la camisa
La billetera cuesta 5 veces el valor de la camisa
Importe total pagado = 2850
Sea el costo de la camiseta = x
Costo del pantalón = x + 400
Costo de la billetera = 5x
La suma del costo debe dar el monto total pagado:
x + x + 400 + 5x = 2850
7x + 400 = 2850
7x = 2850 - 400
7x = 2450
x = 350
Por lo tanto,
Costo de la camisa = $ 350
Pantalón = x + 400 = 350 + 400 = $ 750
Billetera = 5x = 350 * 5 = $ 1750

Five different awards are to be given to three students. Each student will receive at least one award. In how many different ways can the awards be distributed?
Answers
Answer:
Two ways
Step-by-step explanation:
Blue is students and Yellow is the trophies.
Total number of different ways that the awards can be distributed is; 150 ways.
It is clear from the question that the awards and the students are different. Now, each student will receive at least one award.This means that the five different awards could be separated into;
3 + 1 + 1 awards or 2 + 2 + 1 awards.
Now, for one person to get 3 awards and the other 2 people to get one award each, the number of ways is calculated as;⁵C₃ × 3! = 60 ways
Now, for the case where one person is to get 1 award and the other 2 people to get two awards each, the number of ways is calculated as;((⁵C₂ × ³C₂)/2) × 3! = 90 ways
Thus; total number of ways the awards can be distributed = 60 + 90 = 150 ways.Read more at; https://brainly.com/question/20373683

Step-by-step explanation:
Answer:
234 mints
Step-by-step explanation:
if you represent small as s, medium as m, and large as l, you can write the equations as 3s=m 5m=l and 3510=l. We can then substitute 3510 for l and get 5m=3510 divide by 5 and get m=702 put that in the other equation and get 3s=702 divide by 3 and get s=234

2.) Find the vertex only for the following function:
y = -3x^2 + 12x - 5
Answers
Answer:
(2, 7)
Step-by-step explanation:
hope this helps :)
( 1 ) Find by using a formula of (-b/2a, (4ac-b²)/4a)
[tex](\frac{-b}{2a},\frac{4ac-b^2}{4a})\\(\frac{-12}{2(-3)}),(\frac{4(-3)(-5)-(12)^2}{4(-3)})\\(\frac{-12}{-6}),(\frac{60-144}{-12})\\(2,\frac{-84}{-12})\\(2,7)[/tex]
The vertex is at (2,7)
( 2 ) Find by using a derivative (Calculus)
You can also find a vertex by using a calculus. Using a derivative
[tex]y'=-3x^2+12x-5\\y'=-6x+12\\\\[/tex]
Then substitute y' = 0 to get a vertex.
[tex]y'=-6x+12\\0=-6x+12\\-12=-6x\\2=x[/tex]
Then substitute x = 2 in the equation of y = -3x²+12x-5
[tex]y=-3x^2+12x-5\\y=-3(2)^2+12(2)-5\\y=-3(4)+24-5\\y=-12+24-5\\y=-17+24\\y=7[/tex]
x = 2 and y = 7, therefore. The vertex is (2,7)
find the explicit formula for the following sequence.
15, 29, 49, 75, 107,....
Answers
Answer:
Step-by-step explanation:
We are given the sequence
[tex]15, 29, 49, 75, 107\\15->29 = 14\\29 -> 49 = 20\\49->75 = 26\\75 -> 107 = 32\\14, 20, 26, 32\\14 -> 20= 6\\20 -> 26 = 6\\26 -> 32 = 6\\\\6, 6, 6\\6->6 = 0[/tex]
Since we had to find the differences twice, it is a second degree polynomial
[tex]y = an^2 + bn + c\\plugging \: in \: n = 1, 2, 3...\\the \: sequence \: is \\a+b+c, 4a + 2b + c, 9a + 3b + c...\\the \: diff \: under \: is \\3a + b, 5a + b, 7a + b...\\the \: diff \: under \: is \\2a, 2a, 2a...\\so, \\2a = 6\\a = 3\\3(3) + b = 14\\b = 5\\\\a +b + c = 15\\3 + 5 + c = 15\\c = 7\\[/tex]
so,
[tex]y = 3n^2 + 5n + 7[/tex]

The three roots are going to give - 18 so only A and D can be correct. Why minus? because at some point 3 and 2 and - 3 will all be multiplied together. When they are, the result is - 18
So why did I write x + 2 rather than x - 2? Because the roots turn an equation into 0. You are looking for a way to make x + 2 = 0. It will do that when x = - 2
which is what you were given.
Now to get the answer
(x - 3)(x + 3) = x^2 - 9
(x^2 - 9)(x + 2) = x^3 + 2x^2 - 9x - 18 = f(x)
