The answer is 11 because you add all the numbers then divide by the number of terms which would be 44/4=11

Answer:

85% level of the confidence interval is

(26.337, 26.662)

Step-by-step explanation:

Explanation:-

Given the size of the sample 'n' = 295

Mean of the sample x⁻ = 26.5

The Standard deviation of the Population = 2.7

85% level of the confidence interval is determined by

$(x^{-} - Z_{0.15} \frac{S.D}{\sqrt{n} } , x^{-} + Z_{0.15} \frac{S.D}{\sqrt{n} })$

Critical value Z₀.₁₅ = 1.036

85% level of the confidence interval is determined by

$(x^{-} - Z_{0.15} \frac{S.D}{\sqrt{n} } , x^{-} + Z_{0.15} \frac{S.D}{\sqrt{n} })$

$(26.9 -1.036 \frac{2.7}{\sqrt{295} } , 26.5 + 1.036 \frac{2.7}{\sqrt{295} })$

( 26.5 - 0.1628 , 26.5+0.1628)

(26.3372,26.6628)

A culture started with 2000 bacteria. After 4 hours, it grew to 2,200 bacteria. Predict how many bacteria will represent after 9

S_A_V [24]

Y=2000* $e^{k*t}$

2200=2000* $e^{k*4}$

$e^{k}= ( \frac{22}{20} )^{(1/4)}$ 

so,
y at t=8 is 2000*( $( \frac{22}{20} )^{(1/4)}$ )^8
y = 2000(22/20)^2=2000*1.21=2420 thats the answer i hope.

The weather report stated there was a 2/3 chance of rain on Friday, but it was more likely to rain on Saturday than Friday. What

Juliette [100K]

You don't have any choices here, so we can just find the range of the answer. Then, you can select the correct answer.

The probability must be greater than 66.67%: P > 66.67% (or 2/3).

The chance of rain on Friday is 2/3. If it is more likely on Saturday, then it must be more than 2/3. 2/3 is about 66.67% percent.

Answer

A₁ - Journal entry at the time of issue of installment note for cash:

Bank A/c Dr $85,000

To Notes Payable Cr $85,000

A₂– Journal entry at the time of first annual payment:

Notes Payable A/c Dr $9,822

Interest Expense A/c Dr $5,950

To Bank A/c Cr $15,772

Notes payable to be reported in balance sheet at the end of fiscal year:

Notes payable end balance = $85,000 - $9,822 = $75,178

Interest for 2nd year = $75,178 * 7% = $5,262

Installment amount for 2nd year = $15,772

Principal repayment for 2nd year = $15,772 - $5,262 = $10,510

Therefore out of $75,178 notes payable, $10,510 is payable within 1 year.

There $10510 will be shown in balance sheet as current liabilities and

remaining $64,668 will be shown in balance sheet as long term liability.
