I think the reason why the normality of these two proportions is assumed because of n(3.13159) greater than or equal to 10 and n(1 - 3.13159) is greater than or equal to 10. Therefore, for each sample in this research, it must be taken separately.

On February 1, a seller paid $1,140 in annual property tax for the current calendar year. He sold the house with the closing set
tigry1 [53]

Answer:

$288

Explanation:

Since the total property taxes for the year are $1,140, to find the property tax per month we have to divide by 12 ⇒ $1,140 / 12 = $95 per month

The seller is responsible for paying the property taxes during 3 months and 1 day, to find out the amount for that 1 day we divide the monthly tax by 30 = $3.17 per day.

the total seller's credit = ($95 x 3) + $3 = $285 + $3 = $288

*The seller's credit includes all the expenses that must be paid by the seller, while the seller's debit includes all the money that he receives.

a bacteria population starts with 200 bacteriaa and grows at a rate of r(t) = (450.268)e 1.12567t bacteria per hour. How many ba
Virty [35]

Answer:

11,513

Explanation:

Data provided in the question:

Initial bacteria = 200

Growth rate r(t) = (450.268)e^{1.12567t}

Now,

Total growth after 3 hours = \int\limits^3_0 {(450.268)e^{1.12567t}} \, dt

or

Total growth after 3 hours = 450.268\int\limits^3_0 {e^{1.12567t}} \, dt

or

Total growth after 3 hours =450.268[\frac{e^{1.12567t}}{1.12567}]^3_0

[ ∵ \int{d(e^x)}{dt}=\frac{e^x}{\frac{dx}{dt}}]

Thus,

Total growth after 3 hours = 400 × [{e^{1.12567t}]^3_0

or

Total growth after 3 hours = 400 × [{e^{1.12567(3)}-e^{1.12567(0)}]

or

Total growth after 3 hours ≈ 11313

Hence,

Total bacteria after 3 hours = Initial bacteria + Total growth after 3 hours

= 200 + 11313

= 11,513

ser-zykov [4K]

Answer:

The answer is "$400"

Explanation:

The price value of the exercise:

= $127

The expiration date price value is:

= $135

Calculating the profit for Calls buyer:  

= $135-$127  

= $8

The value of 1 call = 100 shares  

calculating the total profit :

=$ 8 × 100  

= $ 800

One alternative purchase price:

= $12

Call option Total purchase price:

=  $12 × 100  

= $1200

The buyer's total loss:

= $1200 - $800

= $400

The Loss for the buyer:  \frac{\text{profit for the seller}}{\text{writer}}

Hence profit for the writer = $400
