For a standard normal distribution, the expression that is always equal to 1 is P(z≤-a)+P(-a≤z≤a)+P(Z≥a). This expression represents all of the possible values in a curve, or in other words, the total area of a curve. According to standard normal distribution, the total area of a curve is always equal to 1.
Make the question more clear please and i think the stem and leaf plot is incorrect.
Answer:
(2x−1)(2x−3)
Step-by-step explanation:
4x² - 6x - 2x + 3
= 4x² - 8x + 3 (by factorization method, or choose any of your favorite methods)
= (2x−1)(2x−3)
The supplement of the angle is 16.
To find a supplement, you take the measure of the angle you know and subtract that from 180. So 180-164=16.
Hope this helps! :D
