Mandy used the input and output in this table to write ratios. She concluded that because they are not all equivalent, this is n
ot a proportional relationship. Is she correct? Explain. A 2-column table with 4 rows. Column 1 is labeled x with entries 1, 2, 5, 10. Column 2 is labeled y with entries 5, 10, 25, 50. 5 over 1 = 10 over 2 = 25 over 5 = 10 over 50 =

Answer:
The correct option is (A) $304.47.
Step-by-step explanation:
The formula to compute the future value (<em>FV</em>) of an amount (A), compounded daily at an interest rate of <em>r</em>%, for a period of <em>n</em> years is:
The information provided is:
A = $300
r% = 1.48%
n = 1 year
Compute the future value as follows:
Thus, the balance after 1 year is $304.47.
The correct option is (A).
Answer:
a. 12
b. 7.200 and 2.683
Step-by-step explanation:
The computation is shown below:
Given that
P = 0.40 and n = 30
a)
The expected value of received e-mails is
= n × p
= 30 × 0.4
= 12
b)
The variance of emails received is
= n × p × (1 - p)
= 30 × 0.4 × 0.6
= 7.200
Now
The standard deviation of emails received is
= sqrt(variance)
= 2.683
We simply applied the above formula
