Answer:
1/12 or 0.0833...
Step-by-step explanation:
There are 36 different possible outcomes for rolling the number cubes. To get a sum of 4 you would need to roll a 1 and 3 (2 possibilities, each cube could roll a 1 or a 3) or a 2 and a 2 (1 possibility, each has to roll the same number). Since there is no 0 or negative numbers, these are your only possibilities. 3 out of 36 possibilities is also equivalent to a 1/12 chance.
Hope this helps
Answer:
A=discrete; B=continuous
Step-by-step explanation:
(a) The number of free dash throw attempts before the first shot is = discrete
(b) The time it takes for a light bulb to burn out.=continuous
Discrete variables are countable in a finite amount of time such as the case of free dash throw attempts
Continuous Variables are more difficult to count. In statistics, time is a Continuous Variable
Answer:
See below ~
Step-by-step explanation:
<u>Things to Find</u>
- Volume of Toy
- Difference of Volumes in Cube and Toy
- Total Surface of Toy
<u>Volume of Toy</u>
- Volume of Hemisphere + Volume (Cone)
- 2/3πr³ + 1/3πr²h
- 1/3πr² (2r + h)
- 1/3 x 3.14 x 16 (8 + 4)
- 1/3 x 50.24 x 12
- 50.24 x 4
- <u>200.96 cm³</u>
<u></u>
<u>Volume of Circumscribing Cube</u>
- Edge length is same as diameter
- V = (8)³
- V = 512 cm³
<u>Difference in Volume</u>
- 512 - 200.96
- <u>311.04 cm³</u>
<u></u>
<u>Slant height of cone</u>
- l² = 4² + 4²
- l² = 32
- l = 4√2 cm = 5.6 cm
<u />
<u>Surface Area of Toy</u>
- CSA (hemisphere) + CSA (Cone)
- 2πr² + πrl
- πr (2r + l)
- 3.14 x 4 (8 + 5.6)
- 12.56 x 13.6
- <u>170.8 cm²</u>
Answer:
1ml : 1m
Step-by-step explanation:
The scale factor of the drawing is the ratio of 1 milliliter and 1 meter; that is, 1ml : 1m.
Speed (S) = Distance (D) / time (t)
First stretch
45 = D / 2
D = 45*2
D = 90 mp
How is the same distance:
Second stretch
S = 90 / t
Average speed (AS):
AS = (S1+S2) / 2
60 = [45+(90/t)] / 2
120 = 45+90/t
120-45 = 90/t
75 = 90/t
t = 90/75
t = 1,2 h
________________________
And now:
S = 90 / t
S = 90 / 1,2
S = 75 mph
