Answer:
a), y=62 b.) c=1 3/5 or 8/5
Step-by-step explanation:
Okay so these are fairly simple lets start with A
4y=248, all we have to do is divide 4 on both sides
4y/4=y
248/4=62
Pretty Simple
For b just subtract 2/5 from both sides
(c+2/5)-2/5=c
2-2/5=1 3/5 or 8/5
Answer:
option no D
Step-by-step explanation:
AS it given that it is a random generator
so it will generate random integers between 1 and 3
so
possible sample space = {1,2,3}
Total no of out comes = 3
Estimated probability that 3 will occur will be obtained by dividing total no of outcomes with total no of possible events to occur
as the occurrence of event is only 1
so
Estimated probability = 1 /3 = 0.33333
Now
The experiment is performed
total outcomes = 14
Total no of like able events that 3 occurred = 4
Actual probability = 4 / 14
= 0.2857
Difference between actual and estimated probability is = 0.3333-0.2857
=0.0421
≅0.04
which is option D
Answer:
one-sixth
multiply the numerator (2) by the number of kids (3) because you are accounting for the fraction of the whole pizza. By doing this you should get 3/6. divide the denominator by the number of kids (3/3) getting you to a value of 1, and replace the denominator, making the amount of pizza one-sixth.
-x+4y=8: Parallel
4x+y=-1: Perpendicular
y=-1/4x+6: neither
y=-4x-3: Perpendicular
