Answer: Kiron's mother earned 4 dollars an hour when she was Kiron's age.
Step-by-step explanation: Let k be Kiron's pay and m be her mother's pay.
From this, we can derive the equation k=3m+6, and since we know k=18 we get
3m+6=18
3m=12
m=4
Answer:

Answer:
x= -1
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
Mean 9.2898
Standard deviation 0.006
Step-by-step explanation:
Let m and s the mean and standard deviation of the non-logarithmized
distribution and , the mean and standard deviation of the logarithmized one.
m = 10,827
Since the CV=0.4, then
s/m=0.4 and
s = 10,827*0.4 = 4,330.8
The mean of the logarithmized distribution is
and the standard deviation is
Integers are like -4,-3,-2,-1,0,1,2,3,4 etc
√49=7, integer
-3⁰=-(3⁰)=-(1)=-1, integer
1.2 times 10⁻²=1.2/100=0.012, not an integer
18/3=6, integer
answer is 3rd one
