1 answer:

5 0

Answer: 3x10^-2

Explanation: Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10.
If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

A person invests 10000 dollars in a bank. The bank pays 6.75% interest compounded monthly. To the nearest tenth of a year, how l

Savatey [412]

Answer: it will take 20.6 years

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

A = $37900

P = $10000

r = 6.75% = 6.75/100 = 0.0675

n = 12 because it was compounded 12 times in a year.

Therefore,

37900 = 10000(1 + 0.065/12)^12 × t

37900/10000 = (1 + 0.00542)^12t

3.79 = (1.00542)^12t

Taking log of both sides, it becomes

Log 3.79 = 12t × log 1.00542

0.579 = 12t × 0.00234752004

0.579 = 0.02817t

t = 0.579/0.02817

t = 20.6 years

Hey there!!

Okay here are the steps you can follow!

9 11/12 ----> improper fraction ----> 119/12
2 8/11 ----> improper fraction ----> 30/11

119/12 - 30/11
(119/12 - 30/11) * 132
11(119) - 12(30)

Romashka-Z-Leto [24]

Answer:

Step-by-step explanation:

A 95% confidence level interval will have 0.52 (lower interval) & 0.68 (upper interval) which means that that if 90 individuals root for North HS then p value is 0.6 which will fall in the 95% confidence interval range.
For the option B the p value will also be same as in case A hence B is true as an alternative hypothesis.
We can calculate P value

Confidence Interval = p ± z $\sqrt{p(1-p)/n}$
