The experimental probability is C. 17%.
17% is derived from the following solution.
14/84 = 0.1666
0.1666 * 100% = 16.66% or 17%
This is based on the result of the experiment conducted.
The theoretical probability of A is 20%.
1/5 = 0.20
0.20 x 100% = 20%
A is only one event out of 5 letters.
Answer:
solve simultaneously
start by labeling them equation 1 and 2 then choose whether you want to make x or y the subject from knew of the equations
Convert decimals to fractions
Multiply both sides by 10
Move expression to the left.
Remove zero.
Solve the quadratic equation.
Remove parenthesis and calculate.
Add the numbers
Separate the solutions
The final solution are
Answer:
x=2
y=1
Step-by-step explanation:
-6x+12=0
take 12 to the other side &it becomes negated then equate
-6x=-12
the negatives cancel out each other and therefore the answer is positive
x=2
4y+5=9
take 5 over to the other side &it becomes negated
4y=9-5
4y=4
y=1
