It would be a 4 in 28 probability (or 1 in 7 if you simplify)
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
first you add up all the number of combs together which gives you 28 combs total
the there were 4 blue combs out of the 28
so the probability it 4 in 28 or 1 in 7
Answer:
t = .64sec and t = 1.56sec
Step-by-step explanation:
This is motion that is modeled by a parabola. The nature of a parabola is symmtrical about some vetical line. That means that if there is an x value where y = 3, for example, when the object is traveling upwards, it will come down after it reaches its max height and be at that same y = 3 height, just at a later time. By this, I mean that you will have 2 times where the height is 7. Besides that, this is a second degree polynomial, so we are expecting 2 values of t.
We are asked to find these 2 times when the height, h, is 7. So we will fill in a 7 for h and factor to solve for t:
To factor this quadratic, we need to get everything on one side of the equals sign and set it equal to 0:
Factor this however your teacher has instructed you to factor quadratics (my guess is that you're probably using the quadratic formula) to get t values of:
t = .64 sec and t = 1.56 sec
Answer:
C
Step-by-step explanation:
proportion can be used to show that the slope of AC is equal to the slope of CG
Slope of AC = (2-0)/(3-0) = 2/3
Slope of CG = (6-2)/(9 -3) = 2/3
So answer is :
C)
2 − 0 6 − 2
------------ = -----------
3 − 0 9 − 3
Answer:
There is 9 total combinations.
Step-by-step explanation:
The pattern goes +1; +2; +3; +4; +5; +6... Since it ends at +6, the next you need to do is +7. 24 + 7 is 31 and that will come next.
Numbers after 31:
