Answer:
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely.
Step-by-step explanation:
I hope this is right
X2 + 14X = -49
+49
x2 + 14X + 49
(x2 + 14X + 7) + 49 - 7 = 0
(X+7)2 + 42 = 0
- 42
(x+7)2 = 42
*square root of both sides)
X + 7 = square root of 42
-7
X = -7 +/- square root of 42
x = -13.48
x = -0.52
and for b, without doing any work my guess is because there is a 0 under the radical, which gives you only one real solution
Step-by-step explanation:
Let the no. be x




Therefore , the no. is 390
