Answer:

Slope =-1/2

P1 (0,4)

P2(-2,5)

Step-by-step explanation:

Slope:

m=(y2-y1)/(x2-x1)

=(3-6)/(2+4)

=-3/6

m=-1/2 = -0.5

Now finding the equation of the line passing through the 2 points:

3 = -1/2 * 2 +q

3 = - 1 +q

q=4

eq. y= -(1/2)x + 4

Let's find 2 other points

x=0

y= - 1/2 *0 +4 =4

(0,4)

x= -2

y= - (1/2)*(-2) +4 = 1+4 = 5

(-2,5)

Answer:

Option C

Step-by-step explanation:

f(1) = -8

f(2) = -5/2×-8 = -20

f(3) = -5/2×-20 = -125

)The following data show the height, in inches, of 11 different plants in a garden: 9 4 10 9 5 2 22 10 3 3 5 After removing the

vaieri [72.5K]

Ur outlier is 22....so we will remove it.

now we find the mean (average) of the data set...
(9+4+10+9+5+2+10+3+3+5) / 10 = 60/10 = 6...this is ur mean

now we subtract the mean from every data value...and find its absolute value
9 - 6 = 3....| 3| = 3
4 - 6 = -2...|-2| = 2
10 - 6 = 4..|4| = 4
9 - 6 = 3....|3| = 3
5 - 6 = -1..|-1| = 1
2 - 6 = -4...|-4| = 4
10 - 6 = 4..|4| = 4
3 - 6 = -3...|-3| = 3
3 - 6 = -3...|-3| = 3
5 - 6 = -1...|-1| = 1

now we find the mean (average) of these numbers...that is ur MAD
(3+2+4+3+1+4+4+3+3+1) / 10 = 28/10 = 2.8

ur answer : on average, the height of the plant varies 2.8 inches from the mean of 6 inches

The amount of time it takes Isabella to wait for the bus is continuous and uniformly distributed between 3 minutes and 15 minute

madam [21]

Answer:

33.33% probability that it takes Isabella more than 11 minutes to wait for the bus

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 that we find a value X lower than x is given by the following formula.

$P(X \leq x) = \frac{x - a}{b-a}$

For this problem, we have that:

Uniformly distributed between 3 minutes and 15 minutes:

So $a = 3, b = 15$

What is the probability that it takes Isabella more than 11 minutes to wait for the bus?

Either she has to wait 11 or less minutes for the bus, or she has to wait more than 11 minutes. The sum of these probabilities is 1. So

$P(X \leq 11) + P(X > 11) = 1$

We want P(X > 11). So

$P(X > 11) = 1 - P(X \leq 11) = 1 - \frac{11 - 3}{15 - 3} = 0.3333$

33.33% probability that it takes Isabella more than 11 minutes to wait for the bus

En cuál de los siguientes procedimientos se resuelven sin error las siguiente operaciones?

myrzilka [38]

D. $\frac{(8)\cdot (-7)\cdot (6)}{(-4)\cdot (-2)\cdot (-3)} = \frac{-336}{-24} = 14$

Por álgebra, recordamos los siguientes dos teoremas llamados teorema del signo para productos:

$(-x)\cdot y = x\cdot (-y) = -x\cdot y$ , $\forall \,x,y\in \mathbb{R}$ (1)

$(-x)\cdot (-y) = x\cdot y$ , $\forall \,x,y\in \mathbb{R}$ (2)

Basados en la información dada en la imagen y los teoremas descritos arriba, el producto del numerador debe ser negativo y el producto del numerador debe ser también negativo, más el resultado de la división debe ser positiva.

Por tanto, la opción D representa a la operación libre de errores.
