Answer:
a) $336
b) $1036
Step-by-step explanation:
a) The interest is computed using the formula ...
I = Prt
where P is the amount invested at rate r for t years.
I = $700·0.08·6 = $336
The interest earned is $336.
__
b) The balance of the account is the sum of the original amount and the interest earned:
balance = $700 +336 = $1036
The balance of the account is $1036.
I know it says instant mirror don't worry about that.
N and 8 in an algebraic expression would be N/8 hope this helps you.
Answer:
The number is either 2 or 1
Step-by-step explanation:
Where x is the unknown number, the square of may be interpreted as x², then the square of the number minus three times the number will be equivalent to
x² - 3x
If this is equal to 2 then
x² - 3x = -2
such that
x² - 3x + 2 = 0
This may be solved using factorization of quadratic equation
x² - 2x -x + 2 = 0
x(x - 2) -1(x- 2) = 0
(x -2)(x-1) = 0
x = 2 or 1

Step-by-step explanation:
Given that after a ham is cured it may be smoked to add flavor or to ensure it lasts longer.
Let X be the smoking time . Then X is N(mu, 8)
a) The sample is drawn at random
b) The sample represents the population
c) Sample size is sufficient to represent the population
b)For 99% conf interval z critical is taken since population std dev is given
Z critical = 2.58
Hence confi interval = 
c) As sample sizes are large and samples are randomly drawn, we can be 99% confident that sample mean falls within this interval
d) If margin of error is only 2, then we must have
