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.
Answer:
Jen has X cats.
Sister has 3x-2 cats.
3x-2 = 4
X = 2
Step-by-step explanation:
We Need To Use Order Of Operations.
5-2 = 3.
32+3 * 4 - 6

Perimeter is the sum of all sides of a shape. For a rectangle, it is the sum of the two lengths and two width measurements. We set up the equations as follows:
l = 2w - 3
P = 8l - 12
P = 2w + 2l
8l -12 = l - 3 + 2l
5l = 9
l = 9/5
9/5 = 2w - 3
w = 12/5
