Answer: Proportional is two varying quantities are said to be in a relation of proportionality, if they are multiplicatively connected to a constant, that is, when either their ratio or their product yields a constant. The value of this constant is called the coefficient of proportionality or proportionality constant.
Answer: 36.32
Step-by-step explanation:
Area of circle is π(r^2)
r is d/2
= 3.14*((6.8/2)^2)
=36.32
The probability that a bone density test score greater than 0.49 calculated using the Zscore formula is 0.312
Given the Parameters :
- Mean, μ = 0
- Standard deviation, σ = 1
- Score, X = 0.49
<u>Recall, the Z score formula</u> :
- Zscore = (X - mean) / standard deviation
Zscore = (0.49 - 0) / 1 = 0.49
<u>The Probability can be expressed thus</u> :
P(Z > 0.49) = 1 - P(Z < 0.49)
Using a probability calculator or normal distribution table ;
P(Z < 0.49) = 0.68793
P(Z > 0.49) = 1 - 0.68793
P(Z > 0.49) = 0.31207
Therefore, the P(Z > 0.49) will be 0.312

Answer:
Part A. (2.5×4)+(21.25×3)=32
Part B. 3.5+(22.75×2)+58
Part C. (2.5x4)+(21.25×3)+32+3.5+(22.75×2)+58
Part D. Perimeter is 212.75ft
Part E. The Sum of 105.75ft and 107ft is 212.75ft. The Commutative Property allows me to add numbers in any order. This is why the answers in parts D and E match.
