Answer:
2 wrongly solutions and 18 right solutions
Step-by-step explanation:
The computation is shown below:
= 20 (problems) × 10 (points)
= 200 points
And it received 176 points
So the difference is of
= 200 - 176
= 24
In the case of wrong solution, the points that are lost is
= 10 + 2
= 12
Now the solutions done wrongly is
= 24 ÷ 12
= 2
And, the solutions does rightly is
= 20 - 2
= 18
Amy:
8 + 5 + 6 + 11 + 4 + 6 +8 = 48
48 divide by 7 = 6.85
chelsea:
7 + 9 + 5 + 3 + 10 + 5 + 8 = 47
47 divide by 7 = 6.71
amy runs more on average.
both mean !
The number of way we can choose 2 males out of 8 is combinations of:
C(8,2)=7*8/2 =56/(1*2)=28
to choose 3 females out of 6
C(6,3)=6*5*4/(1*2*3)=120/6=20
the number of committees is= 28*20=560
9.74 because if you do 604 divided by 62 you will get 9.74 and if you do 9.74 and multiply it by 62 you will get 604<span />
Answer:
None of those
Step-by-step explanation:
3! = 3*2*1 = 6
4! = 4*3*2*1 = 24
24 * 6 = 144
144 is none of the choices
