This morning, the temperature was 80 ⁰F. It dropped 5 degrees per hour. In how many (h) hours did the temperature drop to at mos

t 40 ⁰F? Using the inequality 80 - 5h ≤ 40, which solution makes sense?
a. h ≥ 8 (The temperature dropped for more than 8 hours.)

Selected:b. h ≤ 8 (The temperature dropped for 8 hours or less.)This answer is incorrect.

c. h ≥ 8 (The temperature dropped for 8 hours or more.)

d. h ≤ 8 (The temperature dropped for less than 8 hours.)

SSSSS [86.1K]

Answer:

The large sample n = 190.44≅190

The  large  sample would be required in order to estimate the fraction of people who black out at 6 or more Gs at the 85% confidence level with an error of at most 0.04 is n = 190.44

<u>Step-by-step explanation</u>:

Given  population proportion was estimated to be 0.3

p = 0.3

Given maximum of error E = 0.04

we know that maximum error

M.E = \frac{Z_{\alpha } \sqrt{p(1-p)} }{\sqrt{n} }

The 85% confidence level z_{\alpha } = 1.44

\sqrt{n} = \frac{Z_{\alpha } \sqrt{p(1-p)} }{m.E}

\sqrt{n} = \frac{1.44X\sqrt{0.3(1-0.3} }{0.04}

now calculation , we get

√n=13.80

now squaring on both sides n = 190.44

large sample n = 190.44≅190

<u>Conclusion</u>:-

Hence The  large  sample would be required in order to estimate the fraction of people who black out at 6 or more Gs at the 85% confidence level with an error of at most 0.04 is n = 190.44

A music company offers a loan to buy a drum set for $1500. The simple interest is 11.8% and the loan will be paid in equal month
Mrrafil [7]
Simple interest<span> is determined by multiplying the daily </span>interest<span> rate by the principal by the number of days that elapse between payments. It is expressed as:

I = Prt

I = 1500(.118)(2) = 354

Total amount to pay = $1854
Monthly payment = $77.25

Hope this answers the question. Have a nice day.</span>
