Which of the following is the solution to the system of equations?

drek231 [11]

Answer:

B (3/4,5/4)

Step-by-step explanation:

y = 2- x

$\frac{5}{4} = 2 - \frac{3}{4}$

y = 3x - 1

$\frac{5}{4} = 3 \times \frac{3}{4} - 1$

$\frac{5}{4} = \frac{9}{4} - \frac{4}{4}$

Hope this helps ^-^

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

The Calm Spa charges annual fee of $125 plus $10 per hour of use. The Relax Spa charges annual dues of $230 plus $7 per hour of

Oksi-84 [34.3K]

Answer:

The total number of hours = 35 hours.

Step-by-step explanation:

The annual fee of Calm Spa = $125

Per hour charge of Calm Spa = $10

Annual fee of Relax Spa = $230

Per hour charge of Relax Spa = $7

Now we have to find the number of hours for which both have same cost.

Let the number of hours = x

Thus, 125 + 10x = 230 + 7x

10x-7x = 230 – 125

3x = 105

x = 35

The total number of hours = 35 hours.

Zarrin [17]

101 minutes

Let’s have x represent minutes.

8+0.06x=14.06

Subtract the 8 over

0.06x=6.06

Divide by 0.06 on both sides

X=101
