Answer:
2⁸
When dividing a number by another with the same base, you can simply subtract the denominator's exponent from the numerator's. That gives you
2⁴ ⁻ ⁽⁻⁴⁾ = 2⁽⁴ ⁺ ⁴⁾ = 2⁸
Answer:
x = 15p
-75
Explanation:
remove brackets:
4px + 4 = 64
solving for x --> 4px = 64 - 4 then--> 4px = 60
then diving both sides by 4p --> x = 60\4p --> x = 15p
now solving for x when p is -5
we will substitute the -5 in the equation we got --> x= 15 (-5)
which will give us --> x = -75
Answer:
172
Step-by-step explanation:
42+1= 43
43 x 4= 172
Answer:
<h3>20</h3>
Step-by-step explanation:
Standard deviation of the mean is expressed as:
SM = s/√n
s is the standard deviation of all invoices
n is the sample size of the invoiced
Given
s = $200
n = 100
Required
Standard deviation of the mean
Substitute the given parameters into the given equation
SM = 200/√100
SM = 200/10
SM = 20
Hence the standard deviation of xbar is 20
