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
Answer:
in first question, answer is 12
in second question, answer is -12
Answer:
Shortest Side = 20 feet
Second Side = 23 feets
Third Side = 37 feets
Step-by-step explanation:
Let the shortest side of the desk be x. Hence,
Second side = (x + 3) feets
Third side = (2x - 3) feets
Perimeter = 80ft
x + (x + 3) + (2x - 3) = 80
4x = 80
x = 20
Hence, Second side = (20 + 3) feets
= 23 feets
Third side = (40 - 3) feets
= 37 feets
Hence<u>,</u><u> shortest side is 20 feets, Second side is 23 feets, Third side is 37 feets.</u>
v(-2) = 11, v(0) = 7, v(5) = -3.
hope this helps! :)
