√(1 + √(1 - x²)) - √(1 - √(1 - x²))
√(1 + 1 - x) - √(1 - 1 - x)
√(2 - x) - √(0 - x)
(1.414 - x^1/2) - (0 - x^1/2)
1.414 - 0 - x^1/2 + x^1/2
1.414
Answer:
since the bases (X) are the same only the exponents will be subtracted and b is greater than a to get a negative exponent
Step-by-step explanation:
Find the critical value or test statistic.
![z = \frac{m - \mu}{\sigma/\sqrt{n}} = \frac{404.5 - 400}{24/\sqrt{144}} = \frac{4.5}{2} = 2.25](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7Bm%20-%20%5Cmu%7D%7B%5Csigma%2F%5Csqrt%7Bn%7D%7D%20%3D%20%5Cfrac%7B404.5%20-%20400%7D%7B24%2F%5Csqrt%7B144%7D%7D%20%3D%20%5Cfrac%7B4.5%7D%7B2%7D%20%3D%202.25)
Find P(z > 2.25) using a normal distribution table
P(z > 2.25) = 0.0122
Yes it is true
Hope this helps
