Part A: 12 times it was heads out of 20. So to find the experimental probability, you would take the number of times it landed heads and divide it by the number of times it was fliped. So the answer to Part A would be 12/20 = 3/5
Part B: Theoretical probability is when an event is completly random, the times something should happen out of so many times is the theoretical probability. For example, in a completly random world where everythin were to be random, a coin flipped would land exacfly 1/2 the time heads and 1/2 the time tails.
Hope this helps!
Answer:
42:49
Step-by-step explanation:
6x + 7x = 91
13x = 91
x = 7
6 x 7 = 42
7 x 7 = 49
then 42:49
Answer:
B. 72 cm by 108 cm
Step-by-step explanation:
We know scale is 4 cm:30 ft. So find how many time 30 ft goes into each measurement of playground and then multiply that by 4...
540/30=18
18×4=72
810/30=27
27x4=108
Answer:
first option
Step-by-step explanation:
Given
| x + 4 | = 2
The absolute value function always produces a positive value but the expression inside can be positive or negative, thus
x + 4 = 2 ( subtract 4 from both sides )
x = - 2
OR
- (x + 4) = 2, distribute left side
- x - 4 = 2 ( add 4 to both sides )
- x = 6 ( multiply both sides by - 1 )
x = - 6
Thus solutions are x = - 2, x = - 6
These are represented on the graph by solid blue circles at x = - 2, x = - 6
The first option represents the solution
