Answer:

Step-by-step explanation:

We are asked for the AVERAGE rate of change over two different periods.

We can begin by first figuring out the rate of change between the first and second day by subtracting the amount of parts from day 1 from the amount of parts from day 2.

132 - 66 = 66

We have our first value.

Next, We do the same thing with days 2 and 3. Subtract the amount of parts from day 2 from the amount of parts from day 3.

240 - 132 = 108

Now we are told to find the average. Finding averages is a 2-part process. Add the amounts together, and then dividing. We find averages by adding our values and then dividing by the amount of addends.

66 + 108 = 174

We have our sum of values, now we divide by the amount of addends we had; two.

174/2 = 87

Our final answer is an average of 87.

The correct option is (A) x^6 + x^5 - 2x^4 - 2x^3 + 3x^2 + 6x - 9

Explanation:
The product of two polynomials:
(x^3 + x^2 -3)(x^3 - 2x + 3)

Row1: x^6 x^5 -3x^3
Row2: -2x^4 -2x^3 6x
Row3: 3x^3 3x^2 -9

Add all of the above rows:
x^6 + x^5 - 3x^3 -2x^4 - 2x^3 + 6x + 3x^3 + 3x^2 -9

x^6 + x^5 - 2x^4 - 2x^3 + 3x^2 + 6x - 9 (Option A)

O'Henry Elementary School has a chess club. Of the students in the sixth

kiruha [24]

Answer:

35% of the sixth grade is in the chess club

Step-by-step explanation:

if there are 100 students consider that as 100%

20 is a fifth of 100

20 x 5 =100

since 7/20 is a fraction you multiple the numerator (7) with the same number you multiplied to the denominator (20) which is 5.

7 x 5 = 35

35/100 = 35%

Find the indicated complement. A certain group of women has a 0.55% rate of red/green color blindness. If a woman is randomly

jenyasd209 [6]

Answer:

The probability that the woman selected does not have red/green color blindness is 0.9945.

Step-by-step explanation:

Let X = a woman has red/green color blindness.

It is provided that, in a certain group of women the rate of red/green color blindness is P (X) = 0.0055.

A complement of an event E, is defined as the event of not E.

The probability of complement of an event E is:

$P(E^{c})=1-P(E)$

Compute the probability that the woman selected does not have red/green color blindness as follows:

$P (X^{c})=1-P(X)\\=1-0.0055\\=0.9945$

Thus, the probability of the complement of the event of a woman having red/green color blindness is 0.9945.
