Answer:
2;4;3
Step-by-step explanation:
y=2x²+4x+3
Answer:
2
Step-by-step explanation:
As per the interval, x = 1 and y = 5/2
<u>Substitute x into the expression:</u>
3 - 1 = 2
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.
