experimental
I want to buy more rulers. The tax rate is 6%. How much will I pay if the pack of rulers costs $25?
$26.50
What does the "r" stand for in the formula for a cylinder: 2πr2+2πrh
the radius
When answering a Volume question, should the units be squared (2) or cubed (3)?
*bonus if you can correctly explain why!*
cubed! (3)
because we are multiplying length, width, and height or because it is 3-dimensions

Find the surface area of a rectangular prism with the following attributes:
length = 12 ft
width = 3.4 ft
height = 2 ft
143.2 feet2
Solve for the volume of a rectangular prism that has the following measurements:
length is two and a half meters,
width is one-third of a meter
height is four-fifths of a meter
2/3 or 0.66 meters3
What is the difference between the experimental probability of flipping a tails and the theoretical probability of flipping a tails? (written as a percent)
experimental data:
coin was flipped 12 times
landed on heads 8 times
landed on tails 4 times
1/2 - 4/12 = 0.166666666
16% difference
Triangle TSR, with coordinates T (–3, –2), S (6, 5), and R (6, –2), is reflected over the y-axis. What will be the coordinates of the new figure?
T'(3,-2) S'(-6,5) R'(-6,-2)
Find the surface area of a cylinder with the following attributes:
diameter = 13cm
height = 6.8cm
use the pi key and round your answer to the nearest whole number!
674 cm2
What is the volume of a cylinder that has a radius of seven miles and a height of 22 miles?
use the pi key and round your answer to the nearest whole number.
3387 miles3
The faces of a dice are numbered 1 through 6. The dice is rolled 25 times. It lands on a "2" eight times.
What is the difference between the experimental probability and the theoretical probability? (written as a percent)
8/25 - 1/6 = 0.153333
about 15%
When reflecting over the y-axis, how will the coordinates change?
the x will become opposite, the y will stay the same
I have a box that has the dimensions:
l=10
w=2
h=5
Which attribute should I double to cover the most surface area?
the length!
Doubling the length will increase the surface area from 160 to 300.
Which would hold more cereal? A box with a length of 3in, height of 7in, and a width of 5in. OR a cylinder shaped container with a radius of 3in and a height of 7in?
answer must include the numbers to prove it!
The cylinder holds more (198in3) than the box (105in3)
Luther has a bag of marbles. The bag contains:
3 red marbles
5 black marbles
4 blue marbles
8 yellow marbles
6 green marbles
4 white marbles
What is the probability of pulling a red or yellow marble? (answer as a fraction AND percent)
11/30 = 0.366 = 36%
