Hello!
You have to find what a and b are
3a + 4a = 14
b + 6b = 21
Lets do a first
3a + 4a = 14
Combine like terms
7a = 14
Divide both sides by 7
a = 2
Now lets do b
b + 6b = 21
Combine like terms
7b = 21
Divide both sides by 7
b = 3
Put a and b into the third equation
7( 2 + 3) =
Do what is in parenthesis first
7(5) =
Multiply
35
The answer is 35
Hope this helps!
Answer: F. The Theoretical Probability is Greater than the Experimental Probability.
Step-by-step explanation: Theoretical probability gives you the odds of every outcome. With flipping a coin, the outcome odds of tails would always be 1/2. Experimental probability is the actual outcome that results from trials. During trials, tails was flipped 8 times. We can simplify 8/20 flips to find that tails was flipped 2/5 flips. In decimal form, 1/2 simbolizes .5 or 50%. 2/5 simbolizes .4 or 40%. The theoretical probability is greater than the experimental probability.
