Answer:
B
Step-by-step explanation:
they are similar and 7 / 5 = 21 / 15
So on one die has six numbers, the probability of rolling a 3 on one die is 1/6. So for two die, it would be 1/6 times 1/6= 1/36...
Answer:
and 
Step-by-step explanation:
The first system is
and
We substitute x=-3 and y=-3
and 
Both equations are not satisfied
The next system is
and
We substitute x=-3 and y=-3
and 
Both equations are satisfied
The next system is
and 
We substitute x=-3 and y=-3
and
Both equations are not satisfied
The next system is
and
We substitute x=-3 and y=-3
and
Both equations are not satisfied
Answer:
Step-by-step explanation:
because -3 is a zero, so x=-3
(k-1)(-3)²+k(-3)+1=0
9(k-1)-3k+1=0
9k-9-3k+1=0
6k=8
3k=4
k=4/3
(B)
∵ x=-1 is a zero of p(x)=kx²-4x+k
so k(-1)²-4(-1)+(-1)=0
k+4-1=0
k=-3
7/27 is already in the lowest form it can go.
You can change it into a decimal though. Divide 7 by 27 to receive the decimal of 0.2592. That process usually needs to be done with a pen and paper. You can find the decimal form of any fraction by dividing the numerator and denominator which is also long division.
