.....Yep.
Or is there a second part to this problem?
Answer:
5 and -3
Step-by-step explanation:
x+y =2
X-Y=-8
BY USING SIMULTANEOUS EQUATION
SUBTRACT SUCH THAT
2Y=10
SO Y = 5
X= -3
Answer:
80
Step-by-step explanation:
1/3 of 120 is 40
If 40 leave
People left in party=120-40=80
When b=0
f(x)=ax^2+c
test each
A. with x^2-1, A is false
B. with -x^2-1, B is false
C. cannot find contradiction
D. the axis is actually x=0, 0 is nithere positive nor negative, false
answer is C

Since approximately 68% of a (roughly) normal distribution falls within one standard deviation of the mean, that leaves 32% that falls outside, and by symmetry 16% should lie above one standard deviation of the mean.
