The anwser for NO.4 is (2X+5)(2X-5)
Answer:
equation is y=20(3)^x
Step-by-step explanation:
example:
Solve for x over the integers:
20 (3)^x = 4860
Divide both sides by 20:
3^x = 243
243 = 3^5:
3^x = 3^5
Equate exponents of 3 on both sides:
Answer:
x = 5 hours open with 4860 guest
I believe the answer would be: x=30
SOLUTION:
Step 1 :
In this question, we are told that a marketing research company needs to estimate the average total compensation of CEOs in the service industry.
We also have that: Data were randomly collected from 38 CEOs and the 98% confidence interval was calculated to be ($2,181,260, $5,836,180).
Then, we are asked to find the margin error for the confidence interval.
Step 2:
We need to recall that:
It means that:
where,
putting the values into the equation for the margin of error, we have that:
CONCLUSION:
The margin error for the confidence interval is 1, 827, 460
Probably it's all wrong
4.5 = 10 %If is the same then 4.5*20+45=135
If not then
FV=P(1+r)n45* (1+0.1)20 = 45*6.727=302.737
