The table models an exponential relationship, and the equation of the table is 
<h3>How to analyze the table of values?</h3>
The table of values is given as:
x 0 1 2 3 4
y 4 2 1 1/2 1/4
The above table shows an exponential model
An exponential model is represented as:
When x = 0 and y = 4, we have
Evaluate
a = 4
When x = 1 and y = 2, we have
Evaluate
Substitute 4 for a
4b = 2
Divide both sides by 4
b = 1/2
Substitute 4 for a and 1/2 for b in
Hence, the equation of the table is

Answer:
$507.30
Step-by-step explanation:
-Given the monthly deposits are $425 and the interest rate is 3.5% for 30 years.
-The amount of the investment after 30 years is calculated as;
-Assuming Saul started saving at age 20, his investment term will be 40 yrs.
-His investment amount is thus:
#We subtract to find how much more he would have if he started saving at 20;
Hence, Saul would have $507.30 more had he started saving 10 years earlier.
Answer:
The answer is A,C, and D
Step-by-step explanation:
Answer:
1 is 3 and 2 is y 2/1x
Step-by-step explanation:
if you do not understand 2 then here is a explanation you find slope so take any two point then go over then up the amount over is on the bottom and the amount up on top then simplify if needed
Answer: n = 600.25 ≈ 601 ( sample size)
the minimum sample size of the adults in United State who have sleep deprivation is 601
Step-by-step explanation:
Given that;
the confidence level = 95% = 0.05
the Margin of error E = 4% = 0.04
∴ level of significance ∝ = 1 - C.L
∝ = 1 - (95/100)
= 0.05
Z∝/2 = 0.05/2 = 0.025
Z-critical value at 95% confidence level is OR level of significance at 0.025 = 1.96 (z-table)
Now to calculate the sample size, we say
n = (Z(critical) / M.E )² P ( 1 - P)
now we substitute
n = (1.96 / 0.04)² × 0.5 ( 1 - 0.5)
n = 2401 × 0.5 × 0.5
n = 600.25 ≈ 601
Therefore the minimum sample size of the adults in United State who have sleep deprivation is 601
