Answer:

The required probability is 0.0855

Step-by-step explanation:

Consider the provided information.

The daily revenue has mean $7200 and standard deviation $1200.

\mu_{\bar x}=7200

\sigma=1200

The daily revenue totals for the next 30 days will be monitored.

\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}

\sigma_{\bar x}=\frac{1200}{\sqrt{30}}=219.089

As we know Z=\frac{\bar x-\mu_{\bar x}}{\sigma_{\bar x}}

Substitute \bar x=7500, \mu_{\bar x}=7200\ and\ \sigma_{\bar x}=219.089 in above formula.

Z=\frac{7500-7200}{219.089}=1.3693

From the standard normal table P( Z >1.3693) = 0.0855

Hence, the required probability is 0.0855

Is the square root of 42 rational or irrational? Explain
MA_775_DIABLO [31]

<em>☽------------❀-------------☾</em>

<em>Hi there!</em>

<em>~</em>

\sqrt{42}<em> ≈ </em>6.4807406984087...

<em>So </em>\sqrt{42}<em> is irrational (since the decimal portion doesn't terminate or repeat) </em>

<em>❀Hope this helped you!❀</em>

Please help me on this!

By evaluating, we will see that for x = 7 h(x) exceeds g(x).

<h3>For which value of x does h(x) first exceed g(x)?</h3>

We have:

h(x) = 2*(2)^x

g(x) = 22x - 4

Now we can evaluate both function in the different options:

h(5) = 2*(2)^5 = 64

g(5) = 22*5 - 4 = 106

We can see that for x = 5, h(x) does not exceed g(x), let's try the next one.

h(6) = 2*(2)^6 = 128

g(6) = 22*6 - 4 = 128

So, for x = 6 both functions have the same output, then for x = 7 we will see that h(x) exceeds g(x).

The correct option is B.

Answer:

Step-by-step explanation:

hello :

3x-2y=12

calculate y :   2y = 3x-12   so : y = (3/2)x -6

all coordinates pairs that represents a solutions to the equation are :
