It would be 9x+15

g is right above h

If two lines are cut by a transversal and the consecutive exterior angles are supplementary, then the two lines are parallel. Keep in mind you do not need to check every one of these 12 supplementary angles. Just checking any one of them proves the two lines are parallel

Suppose 2' is a normally distributed random variable with ft = 10.3 and 0 = 3.8. For the following probability,draw an appropria

TiliK225 [7]

GIVEN

The following values are given:

$\begin{gathered} \mu=10.3 \\ \sigma=3.8 \end{gathered}$

SOLUTION

The z-score for the x values 9 and 14 can be calculated using the formula:

$z=\frac{x-\mu}{\sigma}$

For x = 9:

$\begin{gathered} z=\frac{9-10.3}{3.8} \\ z=-0.34 \end{gathered}$

For x = 14:

$\begin{gathered} z=\frac{14-10.3}{3.8} \\ z=0.97 \end{gathered}$

The probability can be calculated as follows:

$P(9\le x\le14)=Pr(-0.34The region that represents the solution is shown below:Therefore, the probability is given to be:[tex]P(9\le x\le14)=0.4671$

The probability is 0.4671.

The elevator at the state capital has a maximum weight capacity of 2000 pounds. If there are 3

Korolek [52]

Answer:

Step-by-step explanation:

Maximum capacity of the elevator = 2000 pounds

Combined weight of the elevator = 428 pounds

A). Let the possible weights that can be added to the elevator = w pounds

B). Therefore, inequality representing this situation will be,

428 + w < 2000

C). By solving the given inequality,

(428 + w) - 428 < 2000 - 428

w < 1572 pounds

Now we draw this inequality on a number line.

Find the area of a circle with a radius of \color{purple}{2}2start color purple, 2, end color purple.

liraira [26]

Answer:

Maybe 12.56

Step-by-step explanation:

Well, the question is a bit hard to read, but I assume the radius is equal to 2?

The formula for the area of a circle is п*r*r

The number п is equal to 3.14

so п*2*2 = 3.14*4 = 12.56

Though if the radius is not 2, try to use that formula and if you cant get it please let me know in the comments
