9) Standard form: 83,023,007 expanded form: 80,000,000 + 3,000,000 + 20,000 + 3,000 + 7
The correct answer is that it will be generated correctly because of the commutative property
16 toy cars.
if 3/8 (6/16) cars are red, then the rest must be blue. so 16-6 = 10
10 cars are blue.
7-4x= 31
Bring over 7 to the other side
Positive 7 changes into negative 7
7-7-4x= 31-7
-4x= 24
Divide by -4 for -4x and 24
-4x/-4= 24/-4
x= -6
Check answer by using substitution method
7-4x= 31
7-4(-6)= 31
7+24= 31
31= 31
Answer : C. x= -6
There are only two possible outcomes in the table that satisfy <em>x</em> ≤ -3; either <em>x</em> = -5 or <em>x</em> = -3. Then
P(<em>x</em> ≤ -3) = P(<em>x</em> = -5) + P(<em>x</em> = -3) = 0.17 + 0.13 = 0.3
