To represent the change in points, you can think of it in two ways:

1.  You will go down 25 points for every wrong answer, so -25 + -25 + -25 would represent what is happening.  They are all negative, so you keeping moving down in value.  

2.  You can also think of this as 3 groups of -25. 

Both answers are -75.  The answer is negative because the change was down in points.

-75 is the integer that represents this situation.

A circle is divided into 10 equal parts what is the angle measure of four of those parts
AleksandrR [38]

<u>Answer</u>:

Four of those parts will have 144 degrees

<u>Explanation</u>:

                          A full circle will always have 360 degree

If the circle is divided into 10 equal parts,

The angle shall divide in 10 parts:

Each slice angle: \frac{360}{10} = 36 degrees.

1 parts has 36 degrees; so:

Four parts will have: 36 * 4 = 144 degrees.

A coin is flipped twice. What is the probability that it will come up once heads and once tails
Illusion [34]

1/2 or 50%, because there are two possibilities out of four.

If you think about flipping a coin twice, there are exactly four possible outcomes:

  Flip 1          Flip 2

1. tails            heads

2. tails            tails

3. heads        tails

4. heads        heads

In two of these possibilities (1 and 3) the coin flipped different sides.

That means 2/4 possibilities matched, and this can be reduced to 1/2

Use the shell method to find the volume of the solid generated by revolving the region bounded by the line y=x+2 and the parabol
Viktor [21]

Answer:

8 π or

25.13 unit^3 to the nearest hundredth.

Step-by-step explanation:

(A)

The height of the shell is (2 + x - x^2) and  the radius is (2 - x).

V = 2π ∫(2 - x)(x + 2 - x^2) dx  between the limits x = 0 and x = 2.

=  2π ∫ (2x + 4 - 2x^2 - x^2 - 2x + x^3) dx

 = 2π ∫ (x^3 - 3x^2 + 4 ) dx

= 2π [ x^4/4 - x^3 + 4x ]  between x = 0 and x = 2

= 2 π [4 - 8 + 8 )

= 2 π * 4

= 8π

= 25.13 unit^3 to the nearest hundredth.
