Answer:
its could be 946-410= 536 and 410+536=946
Hello :
<span>x + 3y = 7....(1)
2x + 4y = 8....(2)
</span>by (1) : x= 7-3y
<span>Substitute in (2) : 2(7-3y)+4y =8
</span>14-6y +4y =8
-2y =-6
y =3
x =7-3(3)
x = -2
<span>Write the solution as an ordered pair:(-2 ,3 )

Answer:
The probability that a student is taking math or computer science is 0.37
Step-by-step explanation:
The probability that a student is taking math =P(M)=33% =0.33
The probability that a student is taking computer science =P(C)= 62%=0.62
The probability that a student is taking math and computer science =P(M∩C)= 58%=0.58
So, the probability that a student is taking math or computer science i.e.P(M∪C)
So, Formula:P(A∪B)=P(A)+P(B)-P(A∩B)
P(M∪C)=P(M)+P(C)-P(M∩C)
P(M∪C)=0.33+0.62-0.58
P(M∪C)=0.37
Hence the probability that a student is taking math or computer science is 0.37

Answer:
Choice B) No.
Step-by-step explanation:
When she starts , she does a sit-up every 222 seconds.
But as she gets tired, each sit-up takes longer and longer to do.
It means, each sit-up takes more time than she did at beginning.
So, it is NOT proportional to the time.
If it is proportional, she should take constant number of sit-ups even she get tired.
