Answer:

-8x+10

Step-by-step explanation:

The expression is: -2(3x+x-5)

Step 1: Using order of operations, combine like terms

-2(4x-5)

Step 2: Distribute -2 to each term in the parentheses:

-8x+10

Hence, the simplified expression is:

-8x+10

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.

Answer:

C) $877.50

Step-by-step explanation:

Time t = 4 years

Principal, p = $750

rate, r = 4.25% = 0.0425

Amount that will be in her account in four years =

Simple interest (prt/100) + principal

750 * 4.25* 4 / 100 + 750

127.5 + 750

= $877.50
