When working with probability questions, the first step is to determine the total possible
outcomes. A chart can be a great visual strategy to assure thoroughness.
Once the probability chart is ready, we find that there are a total of 36 possible
outcomes when rolling two dice. Next, we determine the probability of the following
instances:
a) P = | Dice 1 - Dice 2 | = 3
6/36 = There is a 16% chance that the absolute difference of Dice 1 and Dice 2 will be
3.
b) P = Dice 1 > Dice 2 and P = Second Roll if Dice 1 > Dice 2
15/36 = There is a 41% chance that Dice 1 will be larger than Dice 2.
15/36 = ½ * ½ = ¼ = There is also a 25% chance that you'll get a second roll because
Dice 1 will be larger than Dice 2.
c) P = Dice 1 + Dice 2 = even #
18/36 = There is a 50% chance that the sum of Dice 1 and Dice 2 will be an even
number.
Converting these probabilities to percentages make

"If the average number of cars sold in the first 5 months was 56, and the mean for the
first 6 months was 63, how many cars did they sell in the 6th month?" - ANSWER-A) 98
CARS
16.Renewable energy, what starts as kinetic energy then goes to electric energy? -
ANSWER-A: Windmill (same wording as test) (movement-related = Windmills moving)
3 yellow paper clips, 4 green paper clips, and 7 blue paperclips. What are the chances
that you will randomly get a yellow or green paperclip? - ANSWER-Answer 50%
¾ + ⅖ but they want the numerator in simplest form. - ANSWER-*They want simplest
form*
I got ¾ + 2/5 = 23/20...Which can be reduced to simplest form of 1 & 3/20 & that's why
a= 3
b= 20
answer is 3 for a
A calculator shows 4.21e-18. What does this represent? That it's a scientific notation? -
ANSWER-4.21 x 10−18
A chart about Kayaks and how much shipping you need to charge. The main thing to
know is that 1 foot = 12 inches. Super simple question. You add the shipping charge
, (once you find it on the chart) and the price of the kayak.*Look at both charts**** the 1st
chart tells you about a 9 foot kayak, then the weight of it...***2nd graph how much for
the weight - ANSWER-I got the answer of $524 to ship the kayak in the mail. You must
add the shipping cost of the kayak with the price of the kayak.
A hot spot in the ocean can cause: - ANSWER-new volcanic islands
A rough drawing of what I remember but know what the red lines are half way between
two lines - ANSWER-For me, the number line had the letter "A" close to the number 3.
The question asked which of the numbers below was the letter "A"...(Something like
that) I chose the square root of 8 as the answer.

b) 13/8 = 1.62
A student put a rose under blue light and the rose appears black. Student places rose
under red light and it appeared red. Explain this student's conclusion using the laws of
physics and color. - ANSWER-You think the red rose is red because when white light
falls over the rose it absorbs all other colors other than red and emits red light. When
blue light falls over the rose it absorbs the blue light, but there is nothing to emit so it
appears black. When white light shines on a red object, all of the colors that form the
white light are absorbed except red, which is reflected. This is why the object appears
red. A filter is a transparent material that absorbs some colors and allows others to pass
through. Light is the only source of color. Color pigments (paints, dyes, or inks) show
color by absorbing certain parts of the light spectrum and reflecting the parts that
remain. Color filters work the same way, absorbing certain wavelengths of color and
transmitting the other wavelengths. When blue light is allowed through a blue filter onto
a blue object, the object will still reflect blue and therefore appear blue. But when blue
light from a blue filter hits a red object, the blue will be absorbed and no light will be
reflected, giving the object an appearance of being black.
Another possible response:
-Evaluate the student's validity
This student's conclusion may not be valid because the student never looked at the rose
under white light. The student's explanation also showed misconceptions about the
physics of color.
-Evaluate the student's scientific procedure
Since the student only used two colors of light, the student cannot accurately conclude
the color of the rose. Most objects reflect a spectrum of colors. When white light shines
upon them, they appear to be the color that is reflected the most by the object. The
student should look at the rose under white light to determine its color.
-List another reason using physics to determine why the rose changes color under
certain lights: The colors we see are the color
