Answer:
8.42
Step-by-step explanation:
* means multiply
31.65/5.45 = x/1.45
5.45x = 31.65 * 1.45
5.45x = 45.8925
x = 45.8925/5.45
x = 8.42064220183
Answer:
a = 105 in²
Step-by-step explanation:
Front and back, triangles
a = 2 * (1/2)(5 * 6)
a = 30
Sides, squares
a = 3 * (5 * 5)
a = 75
Total
a = 30 + 75
a = 105 in²

The missing options that makes up the distance formula between two coordinates are; (x₂ - x₁)² and d²
How to find the distance between two coordinates?
The formula for distance between two coordinates is;
d = √[(y₂ - y₁)² + (x₂ - x₁)²]
where;
(x₁, y₁) is the coordinate of the first point
(x₂, y₂) is the coordinate of the second point
Now, this distance formula can also be rewritten when we square both sides to get;
(y₂ - y₁)² + (x₂ - x₁)² = d²
Thus, the missing options that makes up the distance formula between two coordinates are; (x₂ - x₁)² and d²

Answer:
Levers of the factor are High dosage , Low dosage and Placebo.
Step-by-step explanation:
Levels of the factor refer to the number of variations of factor that are used in the experiment. The effect of the factor can be evaluated by these levels.
Here the factor is the experimental drug.
The first group received a low dosage of an experimental drug,
The second group received a high dosage of the drug,
The third group received a placebo.
It can be observed from above three statements that there are 3 levels of factor. These three levels can be used to assess the effect of the experimental drug on 780 participants suffering from high blood pressure.
The factor experimental drug has three levels that are:
High dosage
Low dosage
Placebo
