Answer:
Value of 8x -5y + 7 is 4.
Step-by-step explanation:
Given that:
8x-5y = -3 Eqn 1
It is a true equation.
Now we have to find the value of the given expression
8x -5y + 7
Putting value of 8x-5y from Eqn 1 in the given expression
8x - 5y + 7
-3 + 7
4
Therefore,
8x - 5y + 7 = 4
Hence,
Value of 8x -5y + 7 is 4.
Answer:
Significant difference of 0.20
Step-by-step explanation:
No of student = 20
No of fruits available =4
EAch student is independent of the other.
Hence theoretical probability that a student will choose a banana is=1/4=0.25.
But actual experiments showed that only 1 student selected banana out of 20
Experimental probability that a student will choose a banana is.=1/20 =0.05
The difference between the two = 0.25-0.05 = 0.20
Thus there is a significant difference between Experimental probability that a student will choose a banana and theorical probability that a student will choose a banana
