We are given with the equation <span>f(x) = ax3 + bx2 + cx + d

Substituting, (3,11)

</span><span>10 = 64 a + 16 b + 4c + d

@inflection point, second derivative is equal to zero
</span><span>f'(x) = 3ax2 + 2bx + c 
</span>f''(x) = 6ax + 2b = 0

when x is 4, 24 a + 2b = 0 or 12a + b = 0. 

There are 4 equations, 4 unknowns: answer is

Find the slope of the line through (–9, –10) and (–2, –5). A. –five-sevenths B. seven-fifths C. five-sevenths D. –negative seven
vredina [299]

Answer:

C 5/7

Step-by-step explanation:

We can find the slope of a line using

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

   = (-5 - -10) /(-2 - -9)

   = (-5 +10)/(-2+9)

   5/7

Please answer number 4 and 5
Anestetic [448]

Answer: 4=G 5=A

Step-by-step explanation:

4: since he has only 1 dime 2 nickels and 1 quarter he cant pull out 2 dimes since he doesn't have them, meaning G is not possible.

5: To solve you have to multiply 2 1/2 and 3 1/4, one way is by creating improper fractions and multiply that way. So you will get 5/2 x 13/4 which will give you 65/8. Simply to get 8 and 1/8

A sales analyst listed the probabilities of profits and losses in dollars for a certain company. Find the mean for the probabili
kakasveta [241]

Answer: The mean for the probability distribution will be 69.25.

Explanation:

Since we given that

At\ x_1= -500 ,P(x) = 0.076\\

At\ x_2= -250,P(x)= 0.191\\

At\ x_3=0, P(x)= 0.265\\

At\ x_4=250 , P(x)= 0.316\\

At\ x_5=500 , P(x)= 0.152\\

As we know the formula for expectation of x i.e. known as mean for the probability distribution,

E(x)=x\sum_{1}^{5} P(x)

So, we  apply this formula in our case,

-500\times 0.076+(-250)\times 0.191+0\times 0.265+250\times 0.316+500\times 0.512=69.25

\mu = 69.25

Hence, the mean for the probability distribution will be 69.25.
