Answer:
Average of the draws equals 420
Standard Error = 11.88
Step-by-step explanation:
Given
Solving (a): The average of the draws
This implies that we calculate the sample mean
This is calculated as:
--- Sample Mean = Population Mean
So, we have:
Solving (b): The standard error
This is calculated as:
So, we have:
Using the calculator, we have:
She didnt have enough
she would have 48 dollars in her jar
she she had 2 dollars to little
Answer:
The third answer option is correct. sqrt(x) = x^(1/2). So sqrt(121) = 121^(1/2)
Translating this sentence into symbols: 2(x+3) = x - 5
So 2x + 6 = x - 5 and x = -11
Check: Is 2(-11+3) = -11 -5? Is -16 = -16? YES. x =-11 is right.
