Answer:

\frac{9}{20}

Step-by-step explanation:

experimental probability is the probability of an event occuring when we perform an experiment.

It goes according to the results of the experiment, not the theory behind it.

<u>Probability of landing tails up, therefore, is the number of times it came tails up divided by the total number of times the coin was flipped.</u>

<u />

Hence

P (tails) = 36/80 = 9/20

Which equation describes the circle
deff fn [24]

Answer:

B. (x-5)²+(y+1)² = 49

Step-by-step explanation:

An equation of a circle with center (h, k) and radius r is

\large \boxed{ {(x - h)}^{2}  +  {(y - k)}^{2}  =  {r}^{2} }

We have all given information we need. Our h is 5 - Our k is -1 and our radius is 7

Substitute these values in

\large{ {(x - 5)}^{2}  +  {(y - ( - 1))}^{2}  =  {7}^{2} } \\  \large{ {(x - 5)}^{2}  +  {(y  + 1)}^{2}  =  {7}^{2} } \\  \large{ {(x - 5)}^{2}  +  {(y  + 1)}^{2}  = 49 }

So the answer is B choice.

Find the equivalent exponential expression.<br> (4^2)4
steposvetlana [31]

Answer:

4^8

Step-by-step explanation:

If the second 4 is an exponent, as in (4^2)^4, then multiply the exponents.

(4^2)^4 = 4^(2 * 4) = 4^8

Determine whether the integral is convergent or divergent. ∫[infinity] 2 e^−1/x / x^2 dx : O Convergent O divergent If it is con
monitta

Let f(x)=e^{-1/x}. Then f'(x)=\frac1{x^2}e^{-1/x}>0 for all x\ge2, so f is strictly increasing. As x\to\infty, e^{-1/x}\to e^0=1, so f is bounded above by 1. This is to say,

e^{-1/x}

and the integral of \frac1{x^2} converges over the same domain, so this integral must also converge by comparison.

We have, by setting y=-\frac1x,

\displaystyle\int_2^\infty\frac{e^{-1/x}}{x^2}\,\mathrm dx=\int_{-1/2}^0e^y\,\mathrm dy=e^0-e^{-1/2}=1-\frac1{\sqrt e}
