all students = 150
M = 60
S = 45
M and S = 25
(a) At least one of the two requirements:
M or S = M + S - (M and S) = 60 + 45 - 25 = 80
(b) Exactly one of the two requirements:
(M or S) - (M and S) = 80 - 25 = 55
(c) Neither requirement:
(all students) - (M or S) = 150 - 80 = 70
This is pretty much asking "what squared it 0.09". The answer is 0.3, as 0.3 to the power of 2 is 0.09
Answer:
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
Answer:
33.1%
Step-by-step explanation:
First, calculate the dollar amount of the increase. Subtract $32,500 from $43,250. We get $10,750.
Next, divide this $10,750 by the original salary, $32,500, to determine what fraction of $32,500 is represented by $10,750:
fraction = $10,750/$32.500 = 0.331
Convert this to a percentage by multiplication by 100%: 33.1%
The rate of increase of the saleperson's salary was 33.1%.
Answer:
x=8
Step-by-step explanation:
2x-6+4=14
Combine like terms
2x-2=14
Add 2
2x=16
Divide
x=8
Checking work)
2(8)-2=14
16-2=14
14=14
