The expected number of adults that believe ufos are watching earth is 4

<h3>How to determine the number of adults?</h3>

The given parameters are:

p = 48%

Sample size, n = 8

The expected number of adults that believe ufos are watching earth is calculated as:

E(x) = np

This gives

E(x) = 8 * 48%

Evaluate

E(x) = 3.84

Approximate

E(x) = 4

Hence, the expected number of adults that believe ufos are watching earth is 4

stiks02 [169]
For this case, what you should see is which lines contain point O.
 We have then that the lines that contain this point are:
 EC
 AD
 BO
 We note that three lines contain point O.
 Therefore, three lines intersect at the same point.

You spent $85,489 on your arcade. If you make $10,153 per week on the video games, how many weeks will it take you to make twice
cluponka [151]
To make twice you spend on arcade, you will need to make:
$85,489 x 2  = $<span>170 978
</span>
You make <span>$10,153 a week
Number of weeks needed =  </span>$170 978 ÷ $10,153 
Number of weeks needed = 16.84 ≈ 17 weeks

You will need 17 weeks to make twice as much as you spent in arcade.

Find the solution to dy/dt = 7 y<br><br> satisfying<br> y(9) = 5
AVprozaik [17]
\rm \dfrac{dy}{dt}=7y,\qquad\qquad\qquad y(9)=5

I'm not sure what methods you've learned up to this point but one option is to apply separation of variables:

\rm \dfrac{dy}{y}=7dt

and then integrate from there,

\rm ln|y|=7t+c

exponentiate to isolate y,

\rm |y|=e^{7t+c}

Apply exponent rule,

\rm |y|=e^c e^{7t}

rename this e^c as some new constant, perhaps A,

\rm \pm y=A e^{7t}\qquad\qquad A>0

This A can only be positive, non-zero, but absorbing the plus/minus fixes that restriction,

\rm y=A e^{7t}\qquad\qquad A\ne0

Use your initial information to solve for this unknown value A,

\rm y(9)=A e^{7\cdot9}=5

solving for A, dividing by the exponential,

\rm A=5e^{-63}

So we get a final result of

\rm y(t)=5e^{-63}e^{7t}

apply exponent rule again to get a better looking answer, and factor,

\rm y(t)=5e^{7(t-9)}

Lemme know if too confusing.
