Answer:
P=0.54.
Step-by-step explanation:
We know that in a sample of 6500 automobiles found that 1560 of the automobiles were black, 3120 of the automobiles were sedans, and 1170 of the automobiles were black sedans.
We calculate the number of sedans that are not black:
3120-1170=1950
We calculate the number of black cars that are not sedans:
1560-1170=390
The number of automobiles which are black or a sedan is
1950+390+1170=3510.
The probability that the automobile is black or a sedan is:
P=3510/6500
P=0.54.
Answer:
Adam = 70 pounds
Ben = 40 pounds
C = 60 pounds
Step-by-step explanation:
We can work out some equations based on the given information:
We can call the boys A, B and C
so,
- when all three boys are standing on the scale, it reads 170 pounds.
- Eq(1)
- when Adam stepped off, the scale reads 100. This means that the combined weight of the remaining two boys is 100.
- Eq(2)
- when both Adam and Ben stepped off, the weight of the remaining boy is shown on the scale.

So we already knew the weight of boy C. (it was in the question all along)
pounds
<u>Now to find the individual weights of the remaining boys, we can work our way backwards</u><u> </u>
we can put this value back in Eq(2), to find the weight of boy B.


the
the weight of boy B (Ben) is
pounds
now we can put all of the known weights of the boys in Eq(1) to find the weight of Boy A.





the weight of boy A (Adam) is
pounds
The Answer:
Adam = 70 pounds
Ben = 40 pounds
C = 60 pounds

Answer:
Step-by-step explanation:
let the integers be x,x+1,x+2
x+x+1+x+2≤951
3x≤951-3
3x≤948
x≤316
greatest value of x=316
x+1=316+1=317
x+2=316+2=318
so integers are 316,317,318
Greatest inter=318
