Find the sum of the zeros in the following equation: (2x-1)(x+8)(2x-4)(x-1)

lara [203]

Answer:

$-9\frac{1}{2}$

Step-by-step explanation:

$2x+1=0$

$2x=-1$

$x=-\frac{1}{2}$

$x+8=0$

$x=-8$

$2x-4=0$

$2x=4$

$x=2$

$x-1=0$

$x=1$

$1+2-8-\frac{1}{2}$

$=-1-8\frac{1}{2}$

$=-9\frac{1}{2}$

Sum of fractions $=-9\frac{1}{2}$

What is 1 standard deviation on a

PilotLPTM [1.2K]

Answer:

D. The distance from the mean to an inflection point

Step-by-step explanation:

We rarely encounter the actual formula for the normal PDF. It is ...

$p(x)=\dfrac{1}{\sqrt{2\pi}}e^{-\dfrac{x^2}{2}}$

In fact, the inflection points are at x = ±1, where the curve changes from being concave downward to concave upward.

So, one standard deviation is the distance from the mean to an inflection point.

Miguel biked 14 km in the same amount of time that linda hiked 10 km. Miguel's rate was 4 km/h more than linda's. How fast did e

matrenka [14]

The first thing we must do is define a variable.

We have then:

x: Linda's speed.

Then, by definition, the time traveled is equal to the distance between the velocity.

We have then:

For Linda:

$t = \frac{10}{x}$

For Miguel:

$t = \frac{14}{x + 4}$

Then, since time is the same, then:

$\frac{10}{x} = \frac{14}{x + 4}$

Clearing Linda's speed we have:

$10 (x + 4) = 14x$

$10x + 40 = 14x$

$40 = 14x-10x$

$40 = 4x$

$x = \frac{40}{4}$

$x = 10$

Then, Miguel's speed is:

$x + 4 = 10 + 4 = 14$

Answer:

Linda's speed is 10 Km/h

Miguel's speed is 14 Km/h
