Average rate of change: r=[f(b)-f(a)]/(b-a)

r=-60→[f(b)-f(a)]/(b-a)=-60

b=5; f(b)=-213; a=1; f(a)=27
(-213-27)/(5-1)=(-240)/4=-60

Answer: The <span>two points in the table which create an interval with an average rate of change of -60 are:
x     f(x)
1      27
5   -213</span>

Answer:

1 and 5

Step-by-step explanation:

Since, the rate of change of function f(x) between a to b is \frac{f(b)-f(a)}{b-a} or \frac{f(a)-f(b)}{a-b}

Given,

f(1) = 27, f(2) = 21, f(3) = 3, f(4) = -51 and f(5) = -213,

Thus, the rate of change between 1 and 2 = \frac{f(2)-f(1)}{2-1}=\frac{21-27}{2}=\frac{-6}{2}=-3

Similarly,

The rate of change, between 1 and 3 = -12,

between  1 and 4 = -26,

between  1 and 5 = -60,

between  2 and 3 = -18,

between  2 and 4 = -36,

between 2 and 5 = 78,

between  3 and 4 = -54,

between  3 and 5 = -108,

between 4 and 5 = -162

Hence, the point in the table that create an interval with the rate of change -60 are,

1 and 5.

24 is 3 more than a number p
rewona [7]

Answer: 24 = 3 + P

Step-by-step explanation: 24 is 3 more than a number P can be represented in the equation form of 24 = 3 + P

To solve it:

3 + P = 24

3 - 3 + p = 24 -3

p = 21

A political polling agency predicts candidate A will win an election with 63% of the votes. Their poll has a margin of error of
scoray [572]

Answer:

56% ≤ p ≤ 70%

Step-by-step explanation:

Given the following :

Predicted % of votes to win for candidate A= 63%

Margin of Error in prediction = ±7%

Which inequality represents the predicted possible percent of votes, x, for candidate A?

Let the interval = p

Hence,

|p - prediction| = margin of error

|p - 63%| = ±7%

Hence,

Upper boundary : p = +7% + 63% = 70%

Lower boundary : p = - 7% + 63% = 56%

Hence,

Lower boundary ≤ p ≤ upper boundary

56% ≤ p ≤ 70%

now, if that value is less than 100, then the fellow is "undernourished", otherwise, is overfed.

1/3 (6x +12) - 2(x-7)=19
Morgarella [4.7K]

Answer:

no solution

Step-by-step explanation:

Given

\frac{1}{3}(6x + 12) - 2(x - 7) = 19 ← distribute parenthesis on left side

2x + 4 - 2x + 14 = 19 , that is

18 = 19 ← not possible

This indicates the equation has no solution
