Answer:
a) Lower limit range = 119.7 ≈ 120
b) Upper limit range = 136.8 ≈ 137
Step-by-step explanation:
Given:
a) Lower limit range = 
Therefore,
For the given person of age 43 years old
substituting the value of age in the above equation, we get
Lower limit range = 
or
Lower limit range = 119.7 ≈ 120 beats per minute
b) The upper limit range = 
Therefore,
For the given person of age 43 years old
substituting the value of age in the above equation, we get
Upper limit range = 
or
Upper limit range =
or
Upper limit range = 136.8 ≈ 137 beats per minute
Problem One
Find AM
AM = 71.5 - 22 = 49.5
Step Two
State the Givens.
AM = 49.5
MN = 71.5
MB = x
MP = 97.5
Step Three
Set up the Proportion
AM : NM :: x : PM
49.5 : 71.5 :: x : 97.5
Substitute and solve
49.5 / 71.5 = x / 97.5 Cross Multiply
49.5 * 97.5 = 71.5 * x Combine the numbers on the left.
4860.375 = 71.5 * x Divide by 71.5
4860.375 / 71.5 = x
x = 67.98
Problem Two
Remark
This is just a straight application of the Pythagorean Theorem
a^2 + b^2 = c^2
a = 10
b = 24
c = ??
10^2 + 24^2 = c^2
100 + 576 = c^2
676 = c^2
sqrt(c^2) = sqrt(676)
c = 26 <<<< answer
Answer:
B) A market equilibrium price less than $30
Step-by-step explanation:
When the supply curve increases, it shifts to the right, making the market equilibrium price lower because the oversupply of the quantity causes demand to drive down.
the x s are the independent variable so any direct change to them is changing the independent. like the second one has -5 on the x
