Answer:
Step-by-step explanation:
For example divison and adding 7/6 or 7+6 = 13 But thats not the divison tho...7/6 is 1 so it will be One Hour if they work togther
Answer: Todd used 27 black tiles.
Step-by-step explanation:
Let x represent the number of black tiles that Todd used.
Todd uses 21 white tiles & some black tiles to make a mosaic. This means that the total number of white and black tiles that Todd used is 21 + x
Each tile has an area of 3 square centimeters. This means that the total area covered by the white tiles is
21 × 3 = 63 square centimeters
Also, the total area covered by the black tiles is
3 × x = 3x square centimeters
The mosaic has a total area of 144 square centimeters. This means that
3x + 63 = 144
3x = 144 - 63
3x = 81
x = 81/3 = 27
<u>Answer:</u>
2. The correct answer option is 25%.
3. The experimental probability is 3% greater than the theoretical probability.
<u>Step-by-step explanation:</u>
2. We are given that a number cube is rolled 20 times out of which 5 times it lands on the number 2.
We are to find the experimental probability of getting the number 2.
P (2) = 
= 25%
3. The theoretical Outcomes are: HH HT TH TT
So theoretical probability of getting HH = 
= 25%
Total number of outcomes = 
= 100
So experimental probability of getting HH = 
= 28%
Therefore, the experimental probability is 3% greater than the theoretical probability.
Answer:
24
Step-by-step explanation:
Using the definition of factorial
n! = n(n - 1)(n - 2) ....... × 3 × 2 × 1, hence
4! = 4 × 3 × 2 × 1 = 24
