The Triangle Sum Theorem states that the sum of the angles of a triangle equal 180°.
Therefore,
45° + 62° + k = 180
107° + k = 180
k = 73°
The value of k is 73°

Step-by-step explanation:
From the question we are told that:
Sample size 157
Sample mean



Generally the equation for Standard deviation is mathematically given by



Therefore



N=8. All you have to do is count the amount of numbers after the 2 in 200,000,000. There are 8 numbers after the number 2 which makes n=8.
