Data with a mean that is over 94% (or 90 depending on the grading scale).
each grade you get is a point of data that when added together and getting the mean is over the threshold of "A"

Solve equation (n-1)(n+6)(n+5)=0
Vika [28.1K]
Answer:
1, -6 and -5 

Explanation:
To solve the equation means to get the values of n which satisfy the given equation.
The equation given is:
(n-1) (n+6) (n+5) = 0
This equation will be true if any of the terms (brackets) is equal to zero.
This means that:
either n-1 = 0 .............> n = 1
or n + 6 = 0 ................> n = -6
or n + 5 = 0 ................> n = -5

Hope this helps :)

3x/2y=11 x+y/2=7 igualacion<br> Alguien me puede ayudar
bearhunter [10]

La solución del sistema de ecuaciones es igual a (x, y) = (308/47, 42/47).

<h3>¿Cómo resolver un sistema de ecuaciones linear por igualación?</h3>

Los sistemas de ecuaciones basadas en entidades algebraicas se resuelven mediante procedimientos algebraicos. Grosso modo, el método de resolución por igualación consiste en despejar una variable en dos ecuaciones del sistema para eliminarla y reducir el número de ecuaciones <em>lineales</em> y el número de variables.

A continuación, presentamos una aplicación del método de eliminación:

\frac{3\cdot x}{2\cdot y} = 11

x = \frac{22\cdot y}{3}

x + \frac{y}{2} = 7

x = 7 - \frac{y}{2}

\frac{22\cdot y}{3} = 7 - \frac{y}{2}

\frac{47\cdot y}{6} = 7

y = 42/47

x = 7 - \frac{y}{2}

x = 308/47

La solución del sistema de ecuaciones es igual a (x, y) = (308/47, 42/47).

A random variable follows the continuous uniform distribution between 160 and 340. Calculate the following quantities for the di
Firlakuza [10]

Answer:

a) 0.3889

b) 0.5

c) 0.8333

d) The mean is 250 and the standard deviation is 51.96.

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability of finding a value of X higher than x is:

P(X > x) = 1 - \frac{x - a}{b-a}

The probability of finding a value of X between c and d is:

P(c \leq X \leq d) = \frac{d - c}{b - a}

The mean and the standard deviation are, respectively:

M = \frac{a+b}{2}

S = \sqrt{\frac{b-a}^{2}{12}}

A random variable follows the continuous uniform distribution between 160 and 340.

This means that a = 160, b = 340

a)

P(220 \leq X \leq 290) = \frac{290 - 220}{340 - 160} = 0.3889

b)

P(160 \leq X \leq 250) = \frac{250 - 160}{340 - 160} = 0.5

c)

P(X > 190) = 1 - \frac{190 - 160}{340 - 160} = 0.8333

d)

M = \frac{160 + 340}{2} = 250

S = \sqrt{\frac{340 - 160}^{2}{12}} = 51.96

The mean is 250 and the standard deviation is 51.96.
