Answer:
infinite solution
Step-by-step explanation:
no matter what you have for x, 3x still equals 3x, so it is infinite
Answer:
There appears to be a difference between the pulse rates from samples of adult males and females. The average pulse rate of males is 63.75 while that of females is 75.875.
Coefficient of Variation (male) = 33.44%
Coefficient of variation (female) = 28.35%
Step-by-step explanation:
Mean (male) = 
Mean (female) = 
Standard Deviation (male) = 
Standard Deviation (female) = 
Coefficient of Variation = 
For male, CV = 
%
For female, CV = 
%
Comparison : Pulse rates of males has more variability than that of females since it has a greater coefficient of variation.

Answer:
The value of x is 11
Step-by-step explanation:
<em>Two angles are complementary if the sum of their measures is 90°</em>
Let us use this rule to solve our question
∵ The angle of measure (3x)° and the angle of measure (5x + 2)°
are complementary angles
→ That means their sum equals 90°
∴ 3x + 5x + 2 = 90
→ Add the like terms in the left side
∵ (3x + 5x) + 2 = 90
∴ 8x + 2 = 90
→ Subtract 2 from both sides to move 2 from the left side to the right side
∵ 8x + 2 - 2 = 90 - 2
∴ 8x = 88
→ Divide both sides by 8 to find x
∵ 8x/8 = 88/8
∴ x = 11
∴ The value of x is 11
