Answer:

-3

Step-by-step explanation:

So, heres hopefully what you're looking for. I answered the last one for you, but i cant promise everything on this one lol. Looking at the table, you decrease on the Y from five to one. Thats moving four times. Then the next part, negative one to one. Thats 2 times, coming for a total of 6 movements. Now, to find average rate of change. 6/2. Thats positive 3, and something is wrong with it. Its missing its negative! Heres why, you are decreasing not only on Y, but on X. During decrease, it NEEDS that negative or the answer is completely incorrect. PLEASE do NOT forget... Rate Of Change does not stay consistant. Every single time your moving from something different than these numbers, you gotta be careful and recalculate it or its completely wrong.

I'm here to help. Give me a shout. Sorry if that wasnt too clear, I tried

Answer:

-3.

Step-by-step explanation:

In the table, the y value goes down by -4 and then -2, for a total of -6.

We did this over a period of two units (To go from -1 to 1, we add 2).

-6/2 = -3.

-3 is the average rate of change over the interval.

How to find the derivative of an integral with bounds.
Free_Kalibri [48]

Answer:

The statement of the fundamental theorem of calculus shows the upper limit of the integral as exactly the variable of differentiation. Using the chain rule in combination with the fundamental theorem of calculus we may find derivatives of integrals for which one or the other limit of integration is a function of the variable of differentiation.

Scores on a college entrance examination are normally distributed with a mean of 500 and a standard deviation of 100. What perce
Alla [95]

Answer:

The percentage is P(350 <  X  650 ) = 86.6\%

Step-by-step explanation:

From the question we are told that

   The population mean is  \mu  =  500

     The standard deviation is  \sigma  =  100

The  percent of people who write this exam obtain scores between 350 and 650    

    P(350 <  X  650 ) =  P(\frac{ 350 -  500}{ 100}

Generally  

               \frac{X -  \mu }{\sigma }  =  Z (The \  standardized \  value \ of  \  X )

   P(350 <  X  650 ) =  P(\frac{ 350 -  500}{ 100}

   P(350 <  X  650 ) =  P(-1.5

   P(350 <  X  650 ) =  P(Z < 1.5) -  P(Z <  -1.5)

From the z-table  P(Z <  -1.5 )  =  0.066807

   and P(Z < 1.5  ) =  0.93319

=>    P(350 <  X  650 ) =  0.93319 -  0.066807

=>  P(350 <  X  650 ) = 0.866

Therefore the percentage is  P(350 <  X  650 ) = 86.6\%
