Answer:
The probability of winning the bet is 1/336
Step-by-step explanation:
We should understand that there is only one possible arrangement of the winning selection
Now, the horse that comes first can be selected in 8 ways given that all the horses have equal chances
The horse that comes second can be selected in 7 ways given that all the horses have equal chances
The horse that comes third can be selected in 6 ways given that all the horses have equal chances
Now the total number of ways of selection would be;
8 * 7 * 6 = 336
Since there is only one of the selections that is correct, the probability of making the correct choice is thus 1/336
Answer:
600
Step-by-step explanation:
concert=x
orchestra= 800-x
5x+10(800-x)=7000
5x+8000-10x=7000
-5x=-1000
x=200
800-x=600
Check
200*5=1000
600*10=6000
Answer:
A
Step-by-step explanation:
hope this helps!
Answer:
length :16cm
wide :20cm
We have
Area of inner frame :16*20=320cm²
For
Total area =464cm²
(20+2x)(16+2x)=464cm²
320+32x+40x+4x²=464cm²
4x²+72x+320-464=0
4x²+72x-144=0
4(x²+18x-36)=0
x²+2.9.x+9²=9²+36
(x+9)²=117
x+9=√117
x=10.81-9
x=1.82[approximately]
So
<u>width of frame;20cm+1.82+1.82=23.64cm</u>
<u>length: 16+1.82+1.82=19.64cm</u>
Here length is smaller than breadth.
