Answer:

1

Step-by-step explanation:

Given the following :

Rate of arrival = 40 ( poisson distribution)

Average copying time = 40 seconds (according to an exponential distribution)

Number of machines available = 1

Percentage of time machine is used is Hence ;

Rate of arrival / (Average copying time × number of machines)

40 / (40 × 1)

= 40 / 40

= 1

Find the equation of the exponential function represented by the table below
Gennadij [26K]

Answer:

y = 3^(1 + x)

Step-by-step explanation:

Notice that each time x increases by 1, y increases by a factor of 3.

Thus, the required equation  has the form y = 3^x.

Check:  If x = 0, do we get 3?  No.  Therefore we must modify the exponent:

y = 3^(1 + x)

Check:  If x = 0, do we get 3?  3^(1 + 0) = 3 (correct)

If x = 2, do we get 27?  3(1 + 2) = 3^3 + 27 (correct)

Answer:

.40 x = 35  equation

x = 87.5

Step-by-step explanation:

Of means multiply and is means equals

40% * x = 35

Change percent to decimal form

.40 x = 35

Divide each side by .40

.40x/.40 = 35/.40

x = 35/.40

x =87.5

(3x^4)-5=43<br><br>How?? <br><br>It's supposed to be - 2?​
Sergeeva-Olga [200]

Answer:

I got 2 as an answer

Step-by-step explanation:

( {3x}^{4} ) - 5 = 43 \\ ( {3x}^{4} ) = 43 + 5 \\ ( {3x}^{4} ) = 48 \\  \frac{ {3x}^{4} }{3}  =  \frac{48}{3}

{x}^{4}  = 16 \\  \sqrt[4]{ {x}^{4} }  =  \sqrt[4]{16}  \\ x = 2
