Answer:
the rate of interest be 5%
Step-by-step explanation:
The computation of the interest rate is shown below:
As we know that
Amount = Principal × (1 + rate of interest)^time period
₹32,560 = ₹22,000 × (1 + rate of interest)^8
₹32,560 ÷ ₹22,000 = (1 + rate of interest)^8
1.48 = (1 + rate of interest)^8
After solving this, the rate of interest be 5%
If you go with Blackburn, you have to pay 25 bucks right off, for the web services hosting setup, that's for them to add your account, and allocate resources on their end for you.
After that, for every passing month, you have to pay 5.69 bucks for the service they provide on daily basis.
if you with Randall, they also charge for setup fee, just cheaper, $6 at once, and then for every month is $9.49.
Blackburn for
1 month 5.69(1) + 25
2 months 5.69(2) + 25
3 months 5.69(3) + 25
x months 5.69(x) + 25, or 5.69x + 25
Randall for
1 month 9.49(1) + 6
2 months 9.49(2) + 6
3 months 9.49(3) + 6
x months 9.49(x) + 6, or 9.49x + 6
------------------------------------------------------------------------------------
y = 5.69x + 25
y = 9.49x + 6
If we apply the distributive law to right side of the third choice we get:-
-12x - 9 = -9 - 12x
right side = left side so infinite solutions
Answer:
B. The width of the confidence interval would be smaller.
Step-by-step explanation:
By reducing the confidence level from 99% to 95%, the student assumes that there is more uncertainty about the new confidence interval than the previous one. That, being said, since the results aren't as certain, the confidence interval is widened towards a central average point because the new interval isn't as accurate.
Therefore, the answer is B. The width of the confidence interval would be smaller.
