Answer:
Please check the explanation.
Step-by-step explanation:
Given
P(Z > 1.96)
To determine
What probability expression is equivalent to P(Z > 1.96)
Suppose Z is a standard normal variable.
Therefore,
P(Z > 1.96) = 1 - P(Z ≤ 1.96)
solving
= 1 - Ф(1.96)
= 1 - 0.9750
= 0.0250
Answer:
D) 3x + 15 ≥ 300
Step-by-step explanation:
The rectangle must have a area of AT LEAST 300 square ft, or 300 or greater. Use the greater than or equal sign: ≥ 300.
Note that your are solving for the area, and that this shape is a rectangle. To get the area of the rectangle, simply multiply length and width:
(3) * (x + 5) = Area of rectangle.
Distribute the 3 to all terms:
3(x + 5) = 3x + 15 = Area of rectangle.
Put the two parts together:
3x + 15 ≥ 300.

If you want to convert a fraction to a decimal, divide the top by the bottom. Fractions are basically glorified division.
1/2 = 0.5
And you can convert this to a percent by moving the decimal two places to the right. And change it to a % sign.
0.5 => 50%
