Plug in 5 for y, and 3 for x

(3(5) - 3) + (3)

First, multiply

5 x 3 = 15

Next, subtract

15 - 3 = 12

Finally, add

12 + 3 = 15

15 is your answer

hope this helps

The answer is 15. It’s important to remember PEMDAS like always, remember that. So you’re going to just plug in your Y and your X, so you’ll have (3x5 - 3) + 3
Remembering to do multiplication in the parentheses first, you’ll get (15-3) + 3. Then you finish the parenthesis and get 12+3, and then you finish the problem getting 15.

*** Sorry instead of writing 170 I wrote 270 for the big angle.. other than that it's correct

or another way to solve this is....

we know that a straight line is 180 degrees and the angle APD is 170 all we need to do is subtract 170 from 180 to get the answer of DPB

In a recent awards ceremony, the age of the winner for best actor was 35 and the age of the winner for best actress was 54. For

Arada [10]

Answer:

The actress has the more extreme age because

Step-by-step explanation:

Given

Male Athletes:

$x = 35$

$\=x = 42.1$

$SD = 6.6$

Female Athletes

$x = 54$

$\=x = 34.3$

$SD = 10.1$

Required

Determine which athlete had more extreme age

To do this, we simply calculate the standard z score using

$z = \frac{x - \=x}{SD}$

For the actor:

$z = \frac{35 - 42.1}{6.6}$

$z = \frac{-7.1}{6.6}$

$z = 1.0758$

For the actress:

$z = \frac{54 - 34.3}{10.1}$

$z = \frac{19.7}{10.1}$

$z = 1.950$

Comparing both z values;

The actress has the more extreme age because

<em>It has a positive z value</em>
<em>Its z value is greater than that of the actor</em>

<em></em>
