Answer:
for A plug in those numbers on the right and on the left start with 1 and move up(for example 1,2,3,4,5...)
For b the answer is 2.5x²−4.5x+1.
Step-by-step explanation:
10,000 + 1,000 + 400 + 20 +8
2.36=2 36/100 turn into a fraction
2 36/100= 2 9/25 simplify (I divided by 4)
check if you can simplify again, if you can then do it, if you cant then thats your answer
So, the answer is 2 9/25
Answer:
(a)Yellow=10
Green=38
Relative Frequency of Blue =0.32
Relative Frequency of Red =0.2
Relative Frequency of Green =0.38
(b)50 Red balls
Step-by-step explanation:
In 100 trials, the following were recorded.
- Frequency of Blue Balls = 32
- Frequency of Red Balls = 20
- Relative Frequency of Yellow Balls =0.1
Now, Relative Frequency =Number of Outcome of an Event ÷ Total Number of Trials in the Experiment
Total Number of Trials =100
Therefore:
Therefore, Number of Outcomes of Green balls=100-(32+20+10)
=100-62
Number of Outcomes of Green balls=38
(b)If the Number of Trials is Increased to 250
Expected Outcome of Red Balls =Relative Frequency of Red Balls X 250
She should expect 50 red balls.
