There are 10 seniors in the class, from which 4 should be chosen by the teacher. The order of the chosen students does not matter. This means that we speak of combinations. THe equation for calculating the number of possible combinations is:
C=N!/R!(N-R), where N is the total number of objects and R is the number of objects we select from the N
In our case, N=10, R=4.
C= 10!/4!*6!=10*9*8*7*6!/6!*4*3*2*1=<span>10*9*8*7/24=5040/24=210
There are 210 different ways for the teacher to choose 4 seniors in no particular order.</span>
Answer:
I believe she did 4.5 miles each day
Step-by-step explanation: all I did was divide 52 by 12
Tell me if im wrong
N and n+2 because if n=1 then you do 1+2 and that equals 3. So then you have 1,3
Answer- KG⎯∥JH⎯
the given figure is a trapezium in which CF||DE
Reflection of figure CDEF and shifting it by 3 units does not change the shape of the figure but changes only its position in the x-y plane.
so, the shape of the figure GHJK will be same as that of CDEF.
so sides, KG⎯∥JH⎯
Answer:
See explanation
Step-by-step explanation:
Since 12 is 3 times greater than 4, you simply need to divide all of the ingredients by 3.
Cactus chunks: 4 1/2 divided by 3 is 3/2 or 1 1/2
Crushed Tumbleweed: 8/3 is just 8/3 or 2 2/3
Cactus Juice: 10/4 or 2 1/2
Lizard eggs: 4
Crumbled Flower Petals: 7/4 or 1 3/4
Water: 10/3 or 3 1/3
Hope this helps!
