Answer:
5 is your answer
Step-by-step explanation:
Yes, so first plug in 4 for x
2(4)-3
Then multiply 2x4 which is 8
8-3 is 5
Experimental probability that in a group of 4 students, at least one of them has hazel eyes is 85%.
The experimental probability of an event occurring is the number of times that it occurred when the experiment was conducted as a fraction of the total number of times the experiment was conducted.
According to the question
In a school, 30% of the students have hazel eyes.
The number of hazel eyes in data is 17
The total number of data sets are 20.
Experimental probability = × 100%
= 85%
Hence, experimental probability that in a group of 4 students, at least one of them has hazel eyes is 85%.

Answer:
90%
Step-by-step explanation:
Answer:
Hence, the possible fractions would be:
Step-by-step explanation:
" Mary made a small pan of ziti and a small pan of lasagna. she cut the ziti into 8 equal parts and the lasagna into 9 equal parts" .
Now her family ate 2/3 of the lasagna.
That means her family ate 6 lasanga. ( Since 2/3 of 9 parts is 6{ as (2\3)×9=6} ).
Now it is given that her family ate more lasagna than ziti.
i.e. her family would have eaten less than 6 ziti's.
I.e. they would have eaten either 1,2,3,4 or 5 ziti's.
Hence, the possible fractions would be:
