Answer:
There are 25 possible schedules.
Step-by-step explanation:
The order in which they play soccer is not important(Monday and Tuesday is the same as Tuesday and Monday), and thus the combinations formula is used to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Monday but not Tuesday:
Monday(1) and 2 out of the remaining 7 - 2 = 5. So
Tuesday but not Monday:
Tuesday(1) and 2 out of the remaining 7 - 2 = 5. So
Monday and Tuesday:
Monday and Tuesday(1), plus one out of the remaing 5 days. So
Total:
10 + 10 + 5 = 25
There are 25 possible schedules.
Answer:
Number 4
Standard form - Not sure if right
y = − 0.2734375x^2 − 1.09375x +11.40625
Factored form - Not sure if right
y= 0.0390625 (−7x^2 −28x+292)
Number 5
Either form of the equation other than standard form
Vertex form : y = −(x +3)^2 + 25
Vertex of the parabola
(-3,25)
X and Y intercepts
x-intercept(s): (2,0) ,(−8,0)
y-intercept(s): (0,16)
Answer:this is 25 points but the answer is 240
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
When you add all the the angles of a triangle, they will end up to be exactly 180 degree. When you add the three numbers A, B, and C end up with 180 degree, but D end up with 130 degree, therefore, D is the triangle that cannot exist.
Hope it helps :D
