Answer:
C. 64
Step-by-step explanation:
x° = 1/2[(360° - 2*58°) -2*58°]
x° = 1/2[(360° - 116°)- 116°]
x° = 1/2[244°- 116°]
x° = 1/2[128°]
x° = 64°
x = 64

Answer:
The calcium level that is the borderline between low calcium levels and those not considered low is 
Step-by-step explanation:
From the question we are told that
The mean is 
The standard deviation 
The proportion of the population with low calcium level is
5% = 0.05
Let X be a X random calcium level
Now the P(X < c) = 0.05
Here P denotes probability
c is population with calcium level at the borderline
Since the calcium level is normally distributed the z-value is evaluated as

The critical value for 0.05 from the standard normal distribution table is

=> 
substituting values

=> 
=> 
First off you need to make a equation with 310/5 = 177/3
you then divided 310 by 5 and 177 by 3
310 divided by 5 = 62
177 divided by 3 = 59
the answer you get represents how many miles they traveled per hour.
