Answer:
x=±sqrt (33)
Step-by-step explanation:
y=(x+2)(x-2)
29=x^2-4. x^2=33, x=±sqrt (33)
2/3x - 1/2y = 3 |multiply both sides by 6
4x - 3y = 18
1/2x + y = 5 |multiply both sides by 2
x + 2y = 10
Answer: 4x - 3y and x + 2y = 10.
Answer:
Probability = 0.15%
Step-by-step explanation:
The provided information is:
Let X be the scores of the IQ scores that is normally distributed with mean
and standard deviation
.
That is 

So, 58 is 3 standard deviation left to the mean.
As 99.7% of probability lies within the three standard deviation.
Thus, above three standard deviation is:

Thus, the required probability is 0.15%
