When solving multi-step equations we do them in what order? A reorderable list of 4 items is on the screen. Arrange items so that First step is at the top and Last step is at the bottom. Tab to the listbox, and press the Up and Down
no links to download Arrow keys to move, and the Spacebar to select or unselect an item.
FIRST STEP
Parenthesis
Addition and Subtraction
Exponents
Multiplication and Division
LAST STEP

Solution:

P(x₁ ≥ 70)

Z= (x-µ)/σ

µ = np

σ = √np(1-p)

P(x₁ ≥ 70) = p(x₁-np₁/√np₁ (1-p₁) > 70 – (150*0.51)/√150*0.51*0.49)

= p( z₁ ≥ -1.1433)

= 1-p (z₁ ≤ -1.1433)

= 1- 0.1265

= 0.8735
