Answer:
Tenley has to deposited any amount from $50 and above.
Step-by-step explanation:
From the above question, we can deduce that if your bank balance is below 0, = - , you would be charged $30
Hence,
First she has to pay the bank charges of $30, and to prevent the outstanding charge of $19.95 for generating about charge she has to deposit any amount above $19.95
The amount she has to deposit is
$30 + (x > $19.95)
Assuming x is $20 and above
= $30 + $20 = $50
Hence, Tenley has to deposited any amount from $50 and above.
Equation!!!!!!!!!!!!!!!!!
Answer and Step-by-step explanation:
None of the square roots shown, 75, 12, 18 are rational.
The answer is (4)- multiply 3 by 4.
The following is the correct order of steps to simplify an expression.
1.) Parenthesis
2.) Exponents
3.) Multiply and Divide left to right
4.) Add and Subtract left to right.
Since there are parenthesis in the expression, you must do whatever is inside before anything else.
Inside the parenthesis, there is a subtraction, multiplication, and addition. Since multiplication comes before addition and subtraction in the order of operations, you must do that first. Therefore, the correct answer is multiply 3 by 4.
Answer:
, option c
Step-by-step explanation:
We have the standard deviation for the sample, so we use the t-distribution to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 9 - 1 = 8
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 8 degrees of freedom(y-axis) and a confidence level of 
. So we have T = 2.306
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
Confidence interval:
The confidence interval is the sample mean plus/minus the margin of error. So
The correct answer is given by option c.
